The SCHWAIGER® indoor siren is an easy-to-install Z-Wave Plus device that increases home security in the twinkling of an eye. The siren is simply plugged into a socket and integrated into the Z-Wave network. It becomes part of the security system and can be triggered by various alarm scenes such as intrusion, fire and water alarms. The siren alarms with a three-stage adjustable volume and LEDs as a visual signal. A special feature is the integrated backup battery, with which the siren is active even if the power fails.
