Operating Principle
Street Siren significantly improves the efficiency of the security system.With a high probability, its loud alarm signal and light indication is suffIcient to attract the attention of neighbors and deter intruders. The siren can be seen and heard from far away due to the powerful buzzer and bright LED. When installed properly, it is hard to dismount and switch off the actuated siren: its body is sturdy, the metal net protects the buzzer, the power supply is autonomous, and the on/off button is locked during the alarm. Street Siren is equipped with a tamper button and an accelerometer. The tamper button is triggered when the device body is opened, and the accelerometer is activated when someone’s try to move or dismount the device.
Connecting
Before starting the connection:
- Following the hub user guide, install the Ajax app. Create an account, add the hub, and create at least one room.
- Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
- Make sure that the hub is disarmed and does not update by checking its status in the Ajax app.
Only users with administrator rights can pair the device with the hub.
Pairing the device with the hub:
- Select Add Device in the Ajax app.
- Name the device, scan or type the QR Code (located on the detector body and packaging), and select the location room.

- Tap Add — the countdown will start.
- Switch on the device by holding the power button for 3 seconds.

The on/off button is recessed into the body of the siren and quite tight, you can use a thin solid object to press it.
For detecting and pairing to occur, the device should be located within the coverage of the wireless network of the hub (at the same protected object). The connection request is transmitted brieay: at the moment of switching on the device. Street Siren switches off automatically after failing to connect to the hub. To retry the connection, you do not need to switch it off. If the device has already been assigned to another hub, switch it off and follow the standard pairing procedure. The device connected to the hub appears in the list of devices in the app. The update of the detector statuses in the list depends on the device ping interval set in the hub settings (the default value is 36 seconds).
Please note that only 10 sirens can be connected to one hub

Indication
Event | Indication |
| Alarm | Emits an acoustic signal (the duration depends on the settings) and the LED frame blinks red |
| Switching on | The LED frame blinks once |
| Switching off | The LED frame lights up for 1 second, then blinks three times |
| Registration failed | The LED frame blinks 6 times in the corner then full frame blinks 3 times and the siren switches off |
| Security system is armed (if indication activated) | The LED frame blinks one time and the siren emits a short sound signal |
| Security system is disarmed (if the indication is activated) | The LED frame blinks two times and the siren emits two short sound signals |
|
Siren in the armed mode (if the indication is activated) | The LED frame corner lights up every 2 seconds When StreetSiren is powered externally, its LED frame glows permanently in the corner (for firmware version 3.41.0 and higher) |
|

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 polling period (the Jeweller menu settings in hub settings).
Volume Level Test
Jeweller Signal Strength Test
Attenuation Test
Installing
The location of the siren depends on its remoteness from the hub, and obstacles hindering the radio signal transmission: walls, aoors, large objects.
Check the Jeweller signal strength at the installation location
If the signal level is low (one bar), we cannot guarantee stable operation of the detector. Take all possible measures to improve the quality of the signal. At least, move the detector: even a 20 cm shift can signifIcantly improve the quality of signal reception.
If the detector has low or unstable signal strength even after https://support.ajax.systems/en/manuals/streetsiren/
Street Siren is protected from dust/moisture (IP54 class), which means it can be placed outdoors. The recommended installation height is 2.5 meters and higher. Such a height hinders access to the device for intruders. When installing and using the device, follow the general electrical safety rules for electrical appliances, as well as the requirements of regulatory legal acts on electrical safety.
It is strictly prohibited to disassemble the device under voltage! Do not use the device with a damaged power cord.
Mounting
Before mounting StreetSiren, make sure that you have selected the optimal location and it is in compliance with the guidelines of this manual!

Installation process
- If you are going to use an external power supply (12 V), drill a hole for the wire in SmartBracket. Before installation, make sure that there the wire insulation is not damaged!
You need to drill a hole in the mounting panel to lead out the external power supply wire. - Fix SmartBracket to the surface with bundled screws. If using any other attaching hardware, make sure that they do not damage or deform the panel.
Using the double-sided adhesive tape is not recommended either for a temporary nor permanent fixing. - Put StreetSiren on the SmartBracket panel and turn it clockwise. Fix the device with a screw. Fixing the siren to the panel with a screw makes it difficult for intruders to remove the device quickly.
Do not install the siren:
- Near metal objects and mirrors (they can interfere with the RF signal and cause it to fade);
- In the places were its sound can be muffed;
- Closer than 1 m from the hub.
Maintenance
Check the operational capability of StreetSiren regularly. Clean the siren body from dust, spider web, and other contaminants as they appear. Use a soft dry napkin suitable for tech equipment. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the detector. Street Siren can operate up to 5 years from pre-installed batteries (with the detector ping interval of 1 minute) or approximately 5 hours of constant signaling with buzzer. When the battery is low, the security system notiPes the user, and the LED frame corner smoothly lights up and goes out when arming/disarming or when the alarm goes off, including dismounting or unauthorized opening.
