Operating Principle
The siren signiQcantly improves the eUciency 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 suUcient 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 eactivate the actuated siren: the body is Qrm, 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.
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 siren 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 (by pressing on/off button for 3 seconds).

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). If the device was already assigned to another hub, switch off HomeSiren and then perform the standard adding procedure.
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, the siren will switch off after 6 seconds. You may repeat the connection attempt then. To retry the connection, you do not need to turn off the device.
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 devices scanning period (the paragraph on “Jeweller” settings in hub settings).
Jeweller Signal Strenghth 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 joors, largesize objects located within the room.
The device developed only for indoor use.
Check the signal level at the installation location.
The communication r ange is up to 2000 meters if there are noobstacles. Please consider it when choosing an installation place for HomeSiren.
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 signiQcantly improve the quality of reception.
If after moving the device still has a low or unstable signal strength,
use a radio signal range extender.
Recommended installation height — 2.5 meters and more. This will complicate the access to the device for intruders in case of intrusion.
Installation process
- Fix the SmartBracket panel on the surface 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 siren. The tape will run dry in course of time, which may result in the falling and damage of the device. - 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 tamper mode in the Ajax Security System application and then the Qxing tightness of the device on the panel.
In case of any attempt to dismount the siren, you will receive the notiQcation.
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
- closer than 1 m from the hub.
External LED connection
The outside-mount ed 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. Black terminal wire — “+” contact.
Outlet power supply: 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.
Do not use for cleaning the siren any substances containing alcohol, acetone, gasoline and other active solvents.
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 light up and goes out when the armed mode is activated.
