Ajax HomeSiren
HomeSiren Jeweller is a compact indoor siren that delivers a clear alarm sound and also works as a handy everyday indicator. It’s suitable for homes, offices, shops, clinics, schools and other indoor environments where you want local notification for alarms or events.
Adjustable alarm volume
The siren offers adjustable volume from 80 to 100 dB measured at 1 m. That lets you set the sound level to match the building size, location and needs. Lower volume may be appropriate for smaller homes, while larger spaces often require a louder setting.
Adjustable alarm duration
The alarm duration can be set from 3 seconds to 3 minutes in the Ajax app. On some firmware versions, the duration can be up to 15 minutes. This allows you to tailor the siren to the installation requirements and the customer’s preferences.
Built-in LED indicator
HomeSiren has a built-in LED indicator that can show different events and system statuses. It can indicate alarm, arm/disarm, delays and after-alarm, among other things.
Support for external LED indicator
The siren includes a connection for an external LED indicator. Use this if you want a clear visual signal somewhere other than the siren itself, for example by an entrance door.
Chime function for door opening
HomeSiren can be used with a chime function so the siren emits a short sound when a door opens. This requires a compatible door/contact detector in the system. The feature is useful in shops, receptions or homes where you want to be notified when someone enters.
Delay indication
The siren can indicate entry and exit delays. This gives the user a clear audible or visual cue when it’s time to leave the building or to disarm the system at the entrance.
After-alarm indication
HomeSiren can indicate that an alarm has occurred even after the alarm has stopped. This helps users quickly see that the system detected an event before the alarm was reset.
Reliable wireless communication
HomeSiren communicates wirelessly with the Ajax hub using Jeweller technology. The system continuously monitors the connection and notifies you of signal issues, connection loss or tampering attempts.
Long wireless range
The siren offers a wireless range of up to 2,000 meters in open space, making it suitable for both small and larger installations. If needed, the range can be extended with Ajax range extenders.
Up to 5 years of battery life
HomeSiren is powered by two CR123A batteries and can run for up to 5 years under normal use. Battery level is monitored in the Ajax app, so you’ll be notified well before replacement is required.
Tamper protection
The siren has a built-in tamper function that detects if someone tries to remove the device from the wall or detach it from the mounting bracket. If this happens, the system is notified immediately.
Accessories
Ajax HomeSiren Jeweller is supplied with the SmartBracket mounting plate, installation materials, preinstalled batteries and a connector for an external LED indicator. External LED indicator and the door/contact detector for the chime function are selected according to the installation needs.
