Ajax HomeSiren – Wireless indoor siren (beeping noise)

The Ajax mobile app triggers a siren noise by default on mobile devices to notify of alarm and panic activations. However there are times when mobile devices are silenced or turned off 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

Both sirens have adjustable soudnduration and volume settings in the mobile app
