Homematic IP Alarmsirene außen an Hauswand

Alarm Siren – outdoor

Get a loud acoustic signal when someone tries to enter your home without permission. Install the smart outdoor alarm siren, and you’ll be able to keep an eye on everything via the app.

The secure solution for outdoor protection.

No matter what happens, you can retreat into your home and feel at ease. But sometimes we fear for this place – if we find ourselves at night, or there is a spate of burglaries in our area. So that you can still sleep easy, Homematic IP reduces to a minimum the risk of a burglary going unnoticed. The siren frightens off burglars by giving a visual and acoustic alarm. This will alert not only you but the entire neighbourhood, including any passers-by.

Haus mit Schutzschild

A secure home

For even greater security, combine the alarm siren with window and door contacts or motion detectors.


If an intrusion is detected, the siren sounds the alarm with a 100 dB acoustic signal and a very bright LED signal light.

Handy mit Auge

Everything in view

At the same time, the app informs you via push message if something is wrong at 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.

Haken mit Funkwellen

No wiring means flexible installation

Install the alarm siren wherever you choose, for instance in a spot that’s clearly visible from the street and out of reach of a burglar.


Solar cell operation and a weatherproof housing (IP44) mean you can install it in any outdoor location. In an emergency, the integrated tamper contact reports any tampering or disassembly, further increasing security.

zwei Zahnräder

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.

Solarplatte mit Sonne

Sustainable power supply

The siren is particularly low maintenance and independent of mains power, as it is supplied with power autonomously and sustainably via a powerful solar cell.


Enough energy is stored in three NiMH rechargeable batteries for reliable operation even at night or on cloudy days. If necessary, you can recharge the battery pack via the micro USB port.
