Make an alarm heard indoors. Without a bulky sounder.

HomeSiren U brings a clear audible warning and LED indication into a room. Its compact enclosure fits discreetly into an interior, with adjustable volume for the installation.

The right warning for the event.

Set the indoor alarm volume from 81 to 105 dB at one metre and configure which system events activate it. Entry/exit sounds and supported Chime behaviour can help people understand what the alarm is doing.

HomeSiren U needs a compatible hub. It is a sounder, not an intrusion sensor or a substitute for smoke or heat detection.

No cable across the room.

Two included CR123A batteries provide up to five years of operation. Jeweller carries events and commands between the siren and hub, with supervision and low-battery reporting in the app.

Complete the installation. Compatible equipment.

Ajax Hub 2 Plus Alarm Hub

What you need. Fitting and setup.

You need a compatible Ajax hub and the detectors or events that will activate the siren. Fit it indoors on a secure surface, check Jeweller reception and configure the alarm volume and indications. No mains, CAT6 or cable back to the hub is required; the batteries are supplied. Only an optional external LED needs a local wire. Test audibility as part of the complete system without prolonged close exposure to the sounder. Use an outdoor-rated siren for an exposed exterior position.

Secure SmartBracket and the holding screw to a sound surface. Ajax recommends a position at least 2.5 metres high, with good radio reception and a location that is difficult to interfere with.
