Ajax HomeSiren – Wireless indoor siren (beeping noise)

The Ajax mobile app triggers a siren noise on mobile devices by default to notify of alarm and panic activations. However there are times when mobile devices are turned off or silenced and these alarm and panic activations may go by unnoticed. For this reason it is advisable to install one of the two wireless sirens:

  • Home Siren – Beeping noise to alert residents of alarm / panic activations
  • StreetSiren – Loud outdoor siren to alert residents and neighbours and to scare off intruders

The Siren Volume and Actuation Time can be adusted within the Ajax mobile app


Installation and set up

Ready to operate straight out the box: pre-installed battery so there’s do not need to disassemble it. The device can be connected to the hub with one click in the mobile application and can be mounted on the SmartBracket in just a few minutes.



The HomeSiren includes a connector that can be used for an alarm status LED.
