Compatible hubs and range extenders

The detector is compatible only with Ajax hubs with the firmware OS Malevich 2.18 and higher.

The detector also can work without a hub.

Operating principle

FireProtect 2 AC (Heat/Smoke) Jeweller is a wireless fire detector designed for indoor installation. It can operate from a 110-240 V~, 50/60 Hz power supply, and has a built-in backup battery.

The Battery Life Optimization feature must be enabled to ensure such a lifetime for a built-in backup battery.

The detector is equipped with a siren (piezoelectric buzzer) for audible notification of alarms and events with a volume of up to 85 dB (at a distance of 3 m from the detector). The detector is always active and reacts to a fire 24/7, regardless of the system’s security mode.

FireProtect 2 is protected by two tamper buttons. The first tamper informs if someone tries to remove the detector from the SmartBracket mounting panel. The detector responds with LED indication. The users receive notifications via Ajax apps while the monitoring station processes the alarm. The second tamper notifies on the removal of the smoke chamber lid, which is located under the front panel of the detector.

Ajax automation devices respond to FireProtect 2 alarms and perform user-defined actions using automation scenarios. For example, the WallSwitch relay can turn off the ventilation system and turn on emergency lighting when an alarm occurs.

Smoke sensor

FireProtect 2 detects smoke with a bispectral optical sensor. Inside the smoke chamber, the sensor has blue and infrared LEDs which emit light at different wavelengths. This technology allows the detector to determine the size of the volatile particles inside the chamber and respond to smoke.

The smoke chamber in FireProtect 2 is protected from dust, dirt, and insects. Even if dust gets inside and settles, this does not threaten or impair fire detection. The optical system is designed to prevent non-volatile particles from simultaneously getting within the field of blue and infrared LEDs. So that situation does not cause a false alarm.

The HazeFlow 2 software algorithm also protects against false alarms. When an alarm is detected, the algorithm additionally processes the data received from the detector and confirms the alarm.

Heat sensor

Two built-in class A1R thermistors detect a rapid rise and exceeding the temperature threshold in FireProtect 2. Such thermistors notify of alarms when a rapid temperature rise or static temperature is detected in the range of +54°C to +65°C.

FireProtect 2 reports that the temperature threshold has been exceeded as soon as its value exceeds +64°C. The detector reports a rapid temperature rise if the indicator increases by 10°C within one minute. If the temperature indicator rises sharply by 20°C or more, the detector alerts immediately.

Test/Mute button

Тo activate the Test/Mute button, press lightly on the centre of the front panel with your hand. Use a suitable item (mop handle) if you can’t reach up the detector with your hand. Test/Mute is a mechanical button placed under the front panel of the detector.

The button performs several functions:

• In normal mode, it starts the detector self-test.
• When operating in a network of fire detectors that propagate an interconnected fire alarm without a hub, it starts a network coverage area testing.
• In case of an alarm, it mutes the detector alarm or Interconnected Alarm of all fire detectors in the system for 10 minutes.
• In case of a fault or low battery level, it mutes the sound and LED indication for 12 hours.

To run the self-test or network coverage area testing, wait at least 3 minutes after turning on the detector.

Interconnected Fire Detectors Alarm*

All FireProtect 2 AC detectors in the system can synchronously notify about the fire alarm. There are two ways: primary and fallback (both work in parallel).

In case of danger, the initiating detector sends a fire alarm to the hub. The hub initiates the primary interconnect: all fire detectors will activate the built-in sirens in 20 seconds. Meanwhile, the initiating detector activates the fallback interconnection, directly sending the alarm to other fire detectors. Even if the connection with the hub is lost, raising the interconnected fire alarm takes a minute.

The fallback interconnection functionality is available for hubs with OS Malevich 2.19 and higher.

The FireProtect 2 detectors have different sound and LED indications of alarm types to make it easier for users to distinguish between them. In the case of interconnected alarm, all FireProtect 2 detectors indicate exactly the alarm type detected by the initiating detector.

*To comply with AS3786:2014, EN 14604, and EN 50291 standards, enable the fallback interconnection in the hub settings.

Sending events to the monitoring station

An Ajax system can transmit alarms to both PRO Desktop monitoring app and the CMS in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.

FireProtect 2 AC (Heat/Smoke) can transmit the following events:

1. Smoke alarm/restoration.
2. Alarm caused by a rapid rise in temperature. Restoration.
3. Alarm caused by exceeding the threshold temperature. Restoration.
4. Tamper alarm and restoration.
5. Loss/restoration of connection with the hub.
6. Permanent deactivation/activation of the detector.

When an alarm is received, the operator at the security company’s CMS knows what happened and precisely where to dispatch a rapid response team. The addressability of Ajax devices allows sending events to PRO Desktop or the CMS, including the device type, its name, security group, and virtual room. Note that the list of transmitted parameters may vary depending on the CMS type and its communication protocol.

Check the device ID and the loop (zone) number in the device States via the app.

Adding to the system

Before adding a device

1. Install the Ajax app.
2. Log in to your account or create a new one.
3. Select a space or create a new one.
   What is a space
   How to create a space
   

   The space functionality is available for apps of such versions or later:

   • Ajax Security System 3.0 for iOS;
   • Ajax Security System 3.0 for Android;
   • Ajax PRO: Tool for Engineers 2.0 for iOS;
   • Ajax PRO: Tool for Engineers 2.0 for Android;
   • Ajax PRO Desktop 4.0 for macOS;
   • Ajax PRO Desktop 4.0 for Windows.
4. Add at least one virtual room.
5. Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
6. Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.

Only a PRO or a space admin with the rights to configure the system can add a device to the hub.

The detector must be within the coverage area of the hub radio network. To operate via the radio signal range extender, first pair the detector with the hub and then with the range extender. You can do this in the range extender settings in the Ajax app.

How to pair FireProtect 2 with a hub

1. Open the Ajax app and select the hub to add the detector.
2. Go to the Devices   tab and click Add device.
3. Name the detector, then scan or manually input the QR code (located on the detector and the package box). Next, select a room and a group (if Group Mode is enabled).

   

4. Click Add.
   

   If you’ve reached the maximum number of devices the hub can support (depending on the hub model), you’ll receive a notification when attempting to add another device.

5. Turn on the detector by holding the power button for 3 seconds. The hub connection request is sent only if the detector is enabled. If the detector fails to pair with the hub, try again in 5 seconds.
   

   The hub and the device operating at different radio frequencies are incompatible. The device frequency range may vary by region. We recommend purchasing and using Ajax devices in the same region. You can verify the range of operating radio frequencies with the technical support service.

Once added, FireProtect 2 appears in the hub device list in the Ajax app. Device status update depends on the ping interval set in the Jeweller or Jeweller/Fibra settings. The default value is 36 seconds.

FireProtect 2 works with one hub. When connected to a new hub, the device stops sending events to the previous one. Adding the detector to a new hub does not automatically remove it from the device list of the previous hub. This must be done through the Ajax app.

Autonomous operation mode

FireProtect 2 detectors can be used autonomously without connecting to an Ajax hub. In this case, the detector notifies of fire or smoke with only a built-in siren and LED indication. Users don’t receive notifications on any Ajax apps, including Ajax Translator, or PRO Desktop.

Indication

LEDs and the built-in siren of the detector can report alarms as well as certain states of the detector.

Detector testing

Functionality testing

The test allows you to check the status of the detector’s sensors. You can run it in two ways: by pressing the Test/Mute button of the detector and in Ajax apps.

To run the self-test, wait at least 3 minutes after turning on the detector.

If the detector is in an alarm state, the self-test is not available.

To run the test using the Test/Mute button, press the center of the front panel and hold it for 1.5 seconds.

To run the test in the Ajax app:

1. Open the Ajax app.
2. Select the hub if you have several of them or if you are using the Ajax PRO app.
3. Go to the Devices tab.
4. Select FireProtect 2 (Heat/Smoke).
5. Go to the settings by clicking on the gear icon .
6. Click on the Self-test field.

After starting the test, the detector’s red LED flashes 5 times in a row. The detector’s siren activated simultaneously with an LED indication. When the test is over, users receive a notification about the detector state in Ajax apps.

The detector also notifies about the test result with sound and LED indications. If the test is failed and a malfunction is detected, the detector starts to indicate a malfunction 3 seconds after the test is begun: the yellow LED flashes twice, and the siren beeps simultaneously with the LED indication.

The self-test does not start immediately, but no later than 30 seconds after pressing the Test/Mute button or running from the Ajax app.

To stop a self-test, press the Test/Mute button again.

We do not recommend using the detector if no sound and LED indications occur during the self-test. Contact our Technical Support.

Testing at the installation spot

An Ajax system provides several tests to select the correct installation place of devices. Jeweller Signal Strength Test is available for FireProtect 2. The test determines the strength and stability of the signal at the intended location of the device.

To run the test in the Ajax app:

1. Select the hub if you have several of them or if you are using the Ajax PRO app.
2. Go to the Devices tab.
3. Select FireProtect 2 (Heat/Smoke).
4. Go to the settings by clicking on the gear icon .
5. Select Jeweller Signal Strength Test.
6. Perform the test following the tips in the app.

The test does not start immediately, but the waiting time does not exceed the duration of one detector ping interval. The default value is 36 seconds. You can change the detector ping interval in the Jeweller (or Jeweller/Fibra) menu in the hub settings.

Selecting an installation place

The detector is designed for indoor installation only.

The coverage area of one FireProtect 2 AC (Heat/Smoke) is 50 to 60 m², depending on the type of premises.

The detector should be installed in every room. The detector is placed in the center of the ceiling at a distance of 30 cm from light fixtures, chandeliers, or any other decorative objects that may interfere with alarm detection.

If there are beams on the ceiling protruding 30 cm or more, the detector must be installed between every two beams. If the beams protrude by less than 30 cm, installation on a beam in the central part of the ceiling is allowed.

In halls or narrow corridors, detectors should be installed at a distance of no more than 7.5 m from each other.

If the ceiling is sloping, the detector is installed at a distance of 60 cm from the top point of the ceiling. To select an installation place, draw a straight line down from the top of the ceiling. Then, draw a perpendicular from this line to the sloping part of the ceiling. The detector is installed at this point.

We do not recommend mounting the detector on a wall. This installation is acceptable if closely spaced beams or other obstacles interfere with the installation of the detector. Wall mounting is possible only if the detector is placed at a distance of 15–30 cm below the ceiling but above the doorways.

When installing on the wall, ensure the LEDs are visible to the user. It means FireProtect 2 must be installed upside down.

When choosing the location of the detector, consider the parameters that affect its operation:

• Jeweller signal strength.
• Distance between the detector and the hub.
• Obstacles that affect the radio signal: walls, interfloor ceilings, big objects in the room.

Consider the placement recommendations when designing your Ajax system for the object. The security system must be designed and installed by specialists. The list of recommended Ajax partners is available here.

Signal strength

The Jeweller signal strength is determined by the ratio of the number of undelivered/corrupted data packets that are exchanged between the hub and the detector to expected ones within a certain period of time. Signal strength is indicated by the icon on the Devices tab:

• Three bars — excellent signal strength.
• Two bars — good signal strength.
• One bar — low signal strength; stable operation is not guaranteed.
• Crossed out icon — no signal; stable operation is not guaranteed.

Check the Jeweller signal strength at the installation site. If the signal strength is as low as one or zero bars, we cannot guarantee stable operation of the device. In this case, move the device. Repositioning even by 20 cm can significantly improve the signal reception.

If, after relocation, the detector still has a low or unstable signal strength, use a radio signal range extender.

How not to install the detector

• Outdoors. This can lead to the detector failure.
• In places with low or unstable Jeweller signal strength. This can result in connection loss.
• Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.
• In places with fast air circulation. For example, near fans, vents, open windows, or doors. This may interfere with Smoke/Heat detection.
• Opposite any objects with rapidly changing temperature. For example, electric and gas heaters. This can lead to false alarms.
• In the corners of the room. This may interfere with fire detection.
• In bathrooms, showers, or other areas where the temperature changes rapidly. This can lead to false alarms.
• In rooms where the generation of gases/vapors/smoke is part of the operating process. For example, in a garage, where the possibility of a detector’s alarm due to vehicle exhaust gases exists. For such premises we recommend using a detector without a smoke sensor: FireProtect 2 (Heat/CO).
• In very dusty places or areas with a lot of insects. Insects, dust, and other contaminants can settle on the smoke chamber lid and prevent fire detection.
• Near lighting fixtures, decorations, and other interior items that may interfere with the circulation of air in the room. This may interfere with fire detection.
• On surfaces that are usually warmer or colder than the rest of the room. For example, roof traps. Temperature fluctuations can interfere with fire detection.
• In high or inconvenient places. Access to the Test/Mute button is required to mute the alarm and test the detector if it’s used without connection to a hub.

Installation

Make sure that you have selected the optimal installation place and it complies with the requirements of this manual.

Don’t remove the smoke chamber lid during installation. The smoke chamber lid can be removed when the enclosure is disassembled completely. The system identifies this event as a malfunction and the detector reacts with an audible signal. Users and the security company receive a malfunction notification.

During installation and operation of the Ajax security system, adhere to the rules and requirements of regulatory legal acts on electrical safety. Do not disassemble the device while it is energized or use it with a damaged power cable.

Only a competent specialist should install this device.

FireProtect 2 AC detectors do not require an additional surface mount pattress for installation. The detector’s mounting panel is designed for installation on any surface and includes the WAGO terminals for connecting the power cables.

The detector can be installed directly on the surface or using an accessory CableTrunk. Use CableTrunk when it is impossible to route the power cable from the back of the detector and hide it inside walls or ceiling.

CableTrunk is not included in the detector’s complete set and should be purchased separately.

To install the detector:

1. Remove the SmartBracket mounting panel from the detector. To remove the panel, insert a screwdriver into the appropriate hole and turn SmartBracket counterclockwise.
2. Fix the SmartBracket panel to a surface using temporary fasteners. Secure the detector on the SmartBracket mounting panel. To do this, turn the detector clockwise.
3. Run the Jeweller Signal Strength Test. The recommended value is two or three bars.
   

   If the signal strength is a single bar or lower, we cannot guarantee the stable operation of the detector. Consider relocating the device as repositioning even by 20 cm can significantly improve the signal strength. If there is still low or unstable signal after the relocation, use a radio signal range extender.

4. Remove the detector from the mounting panel. Remove SmartBracket from the surface.
5. Remove the protective cover from the mounting panel. To do this, turn the protective cover counterclockwise as shown below.

   

6. Power off the cable that you will connect to the detector. Route the external power supply cable through the hole in the attachment panel.
7. Remove the WAGO terminals from the mounting panel.
8. Connect the wires to the appropriate WAGO terminals: power phase — to L, neutral — to N.
9. Secure the WAGO terminals in the mounting panel. Organize the wires and secure the protective cover.

   

10. Attach the SmartBracket panel with the bundled screws using all fixation points. When using other fasteners, make sure they do not damage or deform the mounting panel.
11. Place the detector on the SmartBracket mounting panel.

    

12. Adjust the position of the detector if necessary.
13. Turn on the external power supply.

It is necessary to perform a self-test after the installation is finished.

Actions to take in case of a fire alarm (Smoke/Heat)

NEVER IGNORE THE ALARM! Always assume the alarm is real, and evacuate from the premises immediately, even if you have doubts about the cause of the alarm signal.

1. Don’t open doors if you feel heat or smoke behind them. Check other exits and use an alternative escape route. Always close doors behind you when leaving.
   

   If heavy smoke enters a room, stay close to the floor and crawl out. If possible, breathe through a wet cloth or try to hold your breath. Be aware that smoke inhalation causes more death than fire.

2. Evacuate as quickly as you can, don’t panic. Save time, don’t pack your things. Arrange a meeting place outside for everyone in the building. Ensure everyone has evacuated safely.
3. Call the fire department immediately, or ask someone nearby. Remember, even small fires can spread rapidly; call the fire department even if the alarm is automatically transmitted to a monitoring station.

NEVER come back to the house on fire.

Malfunctions

When a malfunction is detected, the Ajax app displays a malfunction counter on the device icon. All malfunctions are indicated in the device’s states. Fields with malfunctions will be highlighted in red.

A malfunction is displayed if:

• no connection with the hub or radio signal range extender;
• the detector’s enclosure is open;
• low backup battery charge level;
• hardware malfunction (failure of one or more sensors of the detector).

Maintenance

The detector has a self-test system and does not require the user or installer intervention. The smoke chamber is protected from dust and insects, so there is no need to clean it. We recommend periodically running a self-test to familiarize people with the alarm sound and LED indication.

FireProtect 2 devices connected to the Ajax hubs generally do not require routine testing. All connected devices are constantly monitored for possible faults, low backup battery, and EOL signals.

However, we encourage all users to test FireProtect 2 devices periodically (monthly)* to allow residents of the building to become familiar with the fire alarm signals of the system.

*Please be aware that your local regulation might require more frequent testing (e.g., weekly).

Clean the detector enclosure of dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, gasoline, and other active solvents to clean the device.

The service life of the detector is 10 years. After this period, the sensitivity of the sensors decreases. We recommend replacing the detector with a new one to ensure uninterrupted fire protection at the premises.

The detector must be changed to a new one after the backup battery is discharged.
