FireProtect (FireProtect Plus) is a wireless indoor inflammation detector furnished with a buzzer. It can detect smoke generation and temperature increase and function up to 4 years from a battery and can operate autonomously.
FireProtect (FireProtect Plus) operates within the Ajax security system, by connecting via the protected Jeweller protocol to the hub. The communication range is up to 1,300 meters if there are no obstacles. In addition, the detector can be used as part of third-party security central units due to the Ajax uartBridge or Ajax ocBridge Plus integration module.
The detector is set up via a mobile application for iOS and Android-based smartphones. The user is notified of all events through push notifications, SMS messages and calls (if activated).
The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

FireProtect Operating Principle
FireProtect operates even without connecting to a security system, determining the smoke contamination level of the room and temperature increase (In addition, FireProtect Plus registers a dangerous CO level), including a sharp one - in the autonomous mode and supplied from batteries.
If any fire (smoke) is detected, the detector will switch on a buzzer - the fire siren can be heard from far, and the logo will light red. When connected to a security system, the detector will also send an alarm signal to the hub - the user and private security company will receive the respective notifications.
The detector detects smoke using an optical coupler consisting of an infrared emitter and photoelectric receiver located in a smoke chamber. If smoke penetrates into the chamber, the photoelectric receiver detects it based on the distortion of the infrared ray.
As some materials burn without smoke emission, the detector also records temperature variation. When the function is enabled, the alarm will be actuated, if the room temperature rises up to 60°С and if the temperature rises by 30° during 30 minutes (even if it is below 60°С).
Additionally, the FireProtectPlus detector model has a function to detect a dangerous CO level in the room. If a certain concentration of CO in the air is exceeded, the detector generates an alarm.
The detector activates:
- within 60–90 min at carbon oxide concentration 50 ppm / 0.005%
- within 10–40 min at CO concentration 100 ppm / 0.01%
- within 3 min at carbon oxide concentration 300 ppm / 0.03%.
You can deactivate the siren in case of smoke/inflammation detection by pressing the touch-sensitive button in the center of the detector's logo and via the Ajax Security System application. If the smoke level and temperature do not return to normal, then FireProtect will activate the siren again after 10 minutes.
Connecting the Detector to the Ajax Security System
Connecting to the hub
Before starting connection:
- Following the hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the hub to the application, and create at least one room.
- Go to the Ajax application.
- Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
- Ensure that the hub is disarmed and does not start updates by checking its status in the mobile application.
⚠️ Only users with administrative privileges can add the device to the hub.
How to connect the detector to the hub:
- Select the Add Device option in the Ajax application.
- Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.
- Select Add — the countdown will begin.
- Switch on the device
To make sure that the detector is on, press the on/off button - the logo will light up red for a second.
For the detection and interfacing to occur, the detector should be located within the coverage area of the wireless network of the hub (at a single protected object). Request for connection to the hub is transmitted for a short time at the time of switching on the device.
If the connection to the Ajax hub failed, sensor will work autonomously; switch off the detector for 5 seconds and repeat the attempt.
The detector connected to the hub will appear in the list of devices of the hub in the application. Update of the detector statuses in the list depends on the device inquiry time set in the hub settings, with the default value - 36 seconds.
Connecting the Detector to Third Party Security Systems
To connect the detector to a third party security central unit using the Ajax uartBridge or Ajax ocBridge Plus integration module, follow the recommendations in the manual of the respective device.
The smoke detector always operates in the active mode. When connecting FireProtect to third-party security systems, it is appropriate to place it in a permanently active protection zone.

The Ajax security system allows conducting tests for checking the functionality of connected devices.
The tests do not start straight away but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph on “Jeweller” settings in hub settings).
Pursuant to the requirements of the standard EN50131, the level of the radio signal sent by wireless devices is decreased during the test mode.
Prior to installing FireProtect, check the smoke detector. To test, switch on the device and press the touch-sensitive button in the logo center for 10 seconds - the detector will test the smoke chamber with the electronic simulation of smoke generation and then will switch on the siren for 8 seconds.
You will receive the corresponding notification in the application regarding the test result and detector status.
Installing of the device
Selection of the Detector Location
The performance efficiency of the detector depends on its location.
Location of FireProtect as a security system element determines its remoteness from the hub and presence of any obstacles between the devices, hindering the radio signal and sound transmission: walls, inserted floors, large-size objects located within the room.
Check the signal level at the installation location
If the signal level is one division, we cannot guarantee stable operation of the security system. Take possible measures to improve the quality of the signal! As a minimum, move the device - even 20 cm shift can significantly improve the quality of reception.
If, after moving, the device still has a low or unstable signal strength, use a radio signal range extender ReX.
The detector should be installed at the ceiling in the highest point where hot air and smoke are concentrated.
If there are any beams at the ceiling, protruding by 30 or more centimeters from the ceiling level, then the detector should be installed between every two beams.
Detector installation process
Before installing the detector, make sure that you have selected the optimal location and it is in compliance with the guidelines contained in this manual!
- Fix the SmartBracket panel on the ceiling using bundled screws. After selecting other attachment hardware, make sure that they do not damage or deform the panel.
The double-sided adhesive tape may be only used for temporary attachment of the detector. The tape will run dry in course of time, which may result in the falling and damage of the detector.
- Put the detector on the panel - the detector will blink with the logo, confirming the tamper switching. Turn the detector clockwise to fix it on SmartBracket.
If the LED in the detector logo is not actuated after installation, check the status of the tamper in the Ajax Security System application and then the fixing tightness of the device on the panel.
In case of opening the SmartBracket panel (removing the detector from the ceiling), you will receive the notification.
Do not install the detector:
- outside the premises (outdoors)
- in places with fast air circulation (near a ceiling fan, air conditioner, air exhaust, open doors and windows)
- nearer than a meter from the vertical projection of the cooking surface
- nearby any metal objects or mirrors causing attenuation and screening of the signal
- in a room with the humidity exceeding
Autonomous Use of the Detector
The FireProtect detector can be used autonomously, without connecting to a security system.
- Switch on the detector by pressing the on/off button for 3 seconds (the logo will light up green for 1 second) and conduct testing.
- Determine the optimal location of the detector following the recommendations in the second part of the section "Selection of the Detector Location" of this manual.
- Install the FireProtect detector as described in the section "Installation of the Detector".
In case of the autonomous use, the detector will notify of the detected fire/smoke with a sound signal and light of the logo. To switch off the siren sound, press on the logo (there is a touch-sensitive button under it) or eliminate the cause of the actuated alarm.
Detector Maintenance and Battery Replacement
Check the operational capability of the FireProtect detector on a regular basis.
Clean the detector body from dust, spider web and other contaminations as they appear with a soft dry napkin suitable for equipment maintenance.
Do not use for cleaning any substances containing alcohol, acetone, gasoline and other active solvents.
Any dust that penetrated into the smoke chamber is perceived by the detector as smoke. The dust content of the chamber is compensated up to some level, and then cleaning will be required - the detector will send the respective notification. The detector also signals about the contaminated smoke chamber or a failure using a long sound signal once every minute and a half.
Batteries installed in the detector ensure up to 4 years of autonomous operation. If the batteries are discharged, the security system will send the respective notifications and the detector will activate a sound signal once every 90 seconds.
- if the main batteries are low - a single short signal;
- if the backup battery is low - two short signals;
- if all the batteries are low - three short signals.
