Alarm Siren - indoor

Simply safe: The Homematic IP indoor alarm siren effectively deters burglars with a sound pressure of up to 90 decibels.

  • Effective alarm system: With a 90 dB piezo speaker, the alarm siren provides not only an acoustic alarm, but also a visual alarm by means of LED.
  • Customizable alarm: Set beeps, alarm duration, and alarm activation and deactivation individually.
  • Sabotage protection: The alarm siren is equipped with a sabotage contact that detects tampering attempts.
  • Easy installation: Thanks to radio communication and battery operation, flexible mounting on ceilings and walls is possible.

The Homematic IP alarm siren scares off burglars with a sound pressure of up to 90 decibels. In addition to the powerful siren, two bright LEDs provide additional attention during the alarm and let thieves quickly run off.

Thanks to wireless radio communication, the indoor siren is independent of cables and gives you the opportunity to freely choose the installation location. Thanks to its unobtrusive design, which resembles a smoke detector, the Homematic IP siren can be discreetly mounted on the ceiling - out of reach of potential burglars. Should a burglar nevertheless gain access to the siren, the integrated tamper contact ensures reliable tamper detection and immediately triggers the alarm.
