Operating Principle

StreetSiren signi cantly 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.
StreetSiren 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:

  1. Following the hub user guide, install the Ajax app. Create an account, add the hub, and create at least one room.
  2. Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
  3. 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:

  1. Select Add Device in the Ajax app.
  2. Name the device, scan or type the QR code (located on the detector body and packaging), and select the location room.

  3. Tap Add — the countdown will start.
  4. Switch on the device by holding the power button for 3 seconds.
    AJAX 7661 StreetSiren Wireless Outdoor Siren - Pairing the device with the hub 2

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 brie y: at the moment of switching on the device.
StreetSiren 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

Setting up the processing of detector alarms

Through the Ajax app, you can cone which detector alarms can activate the siren. This can help to avoid situations when the security system noti
LeaksProtect detector alarm or any other device alarm. The parameter is adjusted in the detector or device settings:

  1. Sign in to the Ajax app.
  2. Go to the Devices  menu.
  3. Select the detector or device.
  4. Go to its settings and set the necessary parameters for activating the siren.

Setting the tamper alarm response

The siren can respond to the tamper alarm of devices and detectors. The option is disabled by default. Note that the tamper reacts to the opening and closing of the body even if the system is not armed!

What is a tamper
For the siren to respond to tamper triggering, in Ajax app:

  1. Go to the Devices menu.
  2. Select the hub and go to its settings 
  3. Select the Service menu.
  4. Go to Siren Settings.
  5. Enable the Alert with a siren if the hub or detector lid is open option.

Setting the response to pressing the panic button in the Ajax app

The siren can respond to pressing the panic button in Ajax apps. Note that the panic button can be pressed even if the system is disarmed!
For the siren to respond to pressing the panic button:

  1. Go to the Devices menu.
  2. Select the hub and go to its settings 
  3. Select the Service menu.
  4. Go to Siren Settings.
  5. Enable the Alert with a siren if in-app panic button is pressed option.

Setting the siren after-alarm indication

AJAX 7661 StreetSiren Wireless Outdoor Siren - Setting the siren after-alarm indication

The siren can inform about triggerings in armed system by means of LED indication.

The option functions as follows:

  1. The system registers the alarm.
  2. The siren plays an alarm (duration and volume depend on settings).
  3. The lower right corner of the siren LED frame blinks twice (about once every 3 seconds) until the system is disarmed.

Thanks to this feature, system users and security companies patrols can understand that the alarm has occurred.
The siren after-alarm indication does not work for always active detectors, if the detector was triggered when the system was disarmed.

To enable the siren after-alarm indication, in Ajax PRO app:

  1. Go to siren settings:
    • Hub → Settings  → Service → Siren Settings
  2. Specify what events the sirens will inform about by double blinking before the security system is disarmed:
    • Confirmed alarm
    • Unconfirmed alarm
    • Lid opening
  3. Select the sirens needed. Go back to Siren Settings. The set parameters will be saved.
  4. Click Back. All values will be applied.
    StreetSiren with e version 3.72 and later supports this function.

unauthorized opening

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, ge 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 signiove the quality of signal reception.
If the detector has low or unstable signal strength even after moving, use a ReX radio signal range extender
StreetSiren 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!

AJAX 7661 StreetSiren Wireless Outdoor Siren - Mounting

Installation process

  1. 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.
  2. 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.

  3. 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
    dio remove the device quickly.

Do not install the siren:

  1. near metal objects and mirrors (they can interfere with the RF signal and cause it to fade);
  2. in the places were its sound can be mu
  3. 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.
StreetSiren 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 noti 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.
