πŸ“˜ HomeSiren User Manual

HomeSiren is a wireless home siren with the capacity up to 105 dB. It can be quickly installed and set up, is furnished with a LED (plus allows connecting an external LED), and can operate up to 5 years from a battery.

HomeSiren operates within the Ajax security system, by connecting via the protected Jeweller protocol to the Hub. The communication range is up to 2,000 meters if there are no obstacles.

The siren 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 detector only operates with Hub. Connection to ocBridge and uartBridge integration modules is not provided

The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

Functional elements

  1. Light indicator
  2. Siren buzzer covered with a fabric
  3. SmartBracket attachment panel (perforated part is required for actuating the tamper in case of any attempt to tear off the siren from the surface)
  4. QR code
  5. Tamper button
  6. Socket for connecting an outside-mounted light indicator
  7. On/off button

HomeSiren Operating Principle

The siren significantly improves the efficiency of the security system, being the most operational means of response to the intrusion into a room. With a high probability, its alarm signal will be sufficient to frighten away the intruders.

The device is furnished with a loud buzzer - the sound of the siren can be heard from far. Subject to correct installation, it would be hard to dismount and deactivate the actuated siren: the body is firm, the power supply is autonomous, and the on/off button will be blocked when the security system is set in the guard mode.

Connecting the Siren to the Hub

The HomeSiren siren operates only with the Ajax security system. Up to 10 sirens may be connected to the Ajax Hub.Β 

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 in armed mode 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:

  1. Select the Add Device option in the Ajax application.
  2. Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.

  3. Select Add β€” the countdown will begin.
  4. Switch on the device

For the detection and interfacing to occur, the siren should be located within the coverage area of the wireless network of the hub (at a single protected object).Β 

Request for connection to the Hub is transmitted for a short time at the time of switching on the device.Β 

If the device was already assigned to another hub, switch off HomeSiren and then perform the standard adding procedure.

If the connection to the Ajax Hub failed, the siren will switch off after 6 seconds. You may repeat the connection attempt then.Β 

The siren connected to the hub will appear in the list of devices of the hub in the application. Update of the siren statuses in the list depends on the device inquiry time set in the hub settings, with the default value - 36 seconds.

Performance testing

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 β€œJeweller” settings in Hub settings).

  • Volume Test
  • Signal Strength Test
  • Signal Fade Test

Installing the Siren

Location of the HomeSiren 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.

Recommended installation height - 2.5 meters and more. This will complicate the access to the device for intruders in case of entering. Β 

Siren Installation

Before installing the siren, make sure that you have selected the optimal location and it is in compliance with the conditions contained in this manual!

  1. Fix the SmartBracket panel on the surface using factory-made 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 siren. The tape will run dry in course of time, which may result in the falling and damage of the device.
  2. Put the siren on the SmartBracket panel and turn it clockwise. When installing in the attachment panel, the tamper will switch and the siren will blink with a LED.
    If the light indicator of the siren is not actuated after installation in SmartBracket, 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 any attempt to dismount the siren, you will receive the notification.

Do not install the siren:

  • outside the premises (outdoors)
  • in places where the acoustic signal will be attenuated (inside furniture, behind thick curtains, etc.)
  • nearby any metal objects or mirrors causing attenuation and screening of the signal
  • within any premises with the temperature and humidity beyond the range of permissible limits

The outside-mounted LED connected to the HomeSiren is paralleled with the built-in LED of the device and completely repeats its indication.

For connection, use the contact on the rear side of the siren body and observe the polarity during the connection.Β 

Black terminal wire β€” "+" contact.Β 

Outlet power supply:Β 3 V, 10 mA.

Siren Maintenance and Battery Replacement

Check the operational capability of the HomeSiren on a regular basis.

Clean the siren body from dust, spider web and other contaminations as they appear. Use soft dry napkin suitable for equipment maintenance.Β 

Do not use for cleaning the siren any substances containing alcohol, acetone, gasoline and other active solvents.Β 

The batteries installed in the siren ensure up to 5 years of autonomous operation (with the inquiry frequency by the hub of 1 minute) or at least 6 hours of the buzzer sound. If the battery is discharged, the security system will send respective notices and the LED will smoothly go up and down when the guard mode is activated.Β
