AJAX StreetSiren manual

The AJAX StreetSiren is a wireless street siren with the capacity up to 113 dB. It can be quickly installed and set up, is furnished with bright LEDs, and can operate from a power unit or up to 5 years from batteries.


StreetSiren operates within the Ajax security system, by connecting via the protected Jeweller protocol to the hub. The communication range is up to 1,500 meters if there are no obstacles.


The siren is set up via a mobile application for iOS and Android-based smartphones or a web application. The user is notified of all events through push notifications, SMS messages and calls (if activated).

Operates only with AJAX hubs.

StreetSiren Operating Principle

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


The device is furnished with a powerful buzzer and bright LEDs – StreetSiren can be seen and heard from far. Subject to correct installation, it would be hard to dismount and deactivate the actuated siren: the body is firm, the buzzer is protected by a metal net, there is an autonomous power supply and even the on/off button is locked in case of alarm.


StreetSiren has no tamper to detect removal or tearing-off from the attachment, an accelerometer (motion detector) is used instead. If the accelerometer is switched on, the alarm will be actuated, if the siren is dismounted.

Connecting the StreetSiren to the AJAX Security System

Connecting the StreetSiren to the Hub

Before starting connection:


1. 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.

2. Go to the AJAX application.

3. Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).

4. 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 StreetSiren 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.

AJAX StreetSiren manual

The on/off button is recessed in the body and is rather stiff, you may use a thin solid object to press it

The StreetSiren siren operates only with the AJAX security system. Up to 10 sirens may be connected to the hub.

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. To retry the connection, you do not need to turn off the device.


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

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.

Attenuation Test

Location of the StreetSiren

Location of the StreetSiren 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.

The communication range is up to 1,500 meters if there are no obstacles,  please consider it when choosing an installation place for StreetSiren.


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 siren body has the dust/moisture protection class IP54 – the device may be placed outdoors. Recommended installation height – 2.5 meters and more. This will complicate the access to the device for intruders in case of entering.


In installing and operating the StreetSiren, follow the general electrical safety regulations for using electrical appliances, as well as the requirements of regulatory legal acts on electrical safety.

Installation of the StreetSiren
