Ajax HomeSiren Jeweller User Manual

Introduction

HomeSiren is a wireless home siren with a capacity of up to 100 dB. It is developed for indoor use only. The device can be quickly installed and set up, is furnished with an LED (and allows connecting an external LED), and can operate for up to 5 years on a battery.

HomeSiren operates within the Ajax system, 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).

⚠️ Operates only with Ajax hubs. Connection to ocBridge Plus and uartBridge integration modules is not provided.

Functional elements

Description of the HomeSiren device's functional elements:

1. Light indicator: A visual indicator, typically an LED.

Connecting the Siren to the hub

ℹ️ The HomeSiren siren operates only with the Ajax system. Up to 10 sirens or keypads with a built-in siren 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 the on/off button for 3 seconds).

For 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.

The 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 of 36 seconds.

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.

⚠️ The device developed only for indoor use.

ℹ️ Check the signal level at the installation location.

The communication range is up to 2000 meters if there are no obstacles. 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 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.

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

Installation process

1. 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.

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 tamper mode 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
closer than 1 m from the hub.

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.
