Alarm Siren

If someone tries to enter your home without permission, our smart alarm siren will signal this loudly and immediately.

The secure solution for indoor protection.

At night, in bed, you can hear strange noises coming from the windows. Is it the neighbour’s cat or is it a burglar? Homematic IP helps you prevent a burglar from entering your home unnoticed. If someone is detected trying to gain unauthorised entry, the alarm siren sounds loudly and clearly.

A secure home

For the best possible protection, combine the alarm siren with window and door contacts or motion detectors.

If an intrusion is detected, the siren sounds the alarm with a loud acoustic signal and two very bright LED signal lights.

Everything in view

The app informs you immediately via push message if something is wrong in your home.

The Homematic IP app always gives you an up-to-date overview of your smart home – so you can feel secure even when you’re out and about.

Individual choice of alarm signals

Choose the type of alarm signal – acoustic and visual – and alarm duration you want.

You set all the functions in the Homematic IP app. And connect the alarm siren to a Homematic IP smoke detector, too. That way, in the event of a fire, you will not only be informed by the alarm on the smoke detector but also by the alarm siren – and be twice as safe!

Reliable and fail-safe

The alarm siren remains active even if the Access Point is destroyed, for example by a burglar.

The alarm is triggered even if the internet or cloud connection is inactive. With Homematic IP, this is ensured by direct communication between the devices.

No wiring means flexible installation

Install the alarm siren inconspicuously wherever you choose, ideally out of reach of a burglar.

Its battery operation means that it can be installed in any indoor location. In an emergency, the integrated tamper contact reports any tampering or disassembly, further increasing security.
