Description from Gira Shop
Battery-operated combined smoke alarm device heat detector for home use with VdS (Association of German Property Insurers) recognition and interface for acceptance of a radio or relay module.
The smoke detection operates based on the photo-electric scattered light principal without radioactive particles. The smoke alarm device detects smoke or heat accumulation early and emits a warning signal before the concentration of smoke becomes hazardous to people.
Alarm signalling occurs via a loud pulsing alarm tone and a flashing ring indicator.
Up to 40 smoke alarm devices can be interconnected (wired or per radio module). When interconnected, all smoke alarm devices emit an alarm signal if one detects smoke or heat.
The interface enables the fitting of a radio or relay module with simultaneous use of the networking terminal.
With the optional 230 V base for smoke alarm device 2331 02, power supply with mains voltage (230 V) is possible.
- Integrated test button for function test
- Automatic self-test
- Battery replacement indicator
- Soiling/fault display
- Daylight detection for prevention of fault messages by night (e.g. battery replacement message)
In rooms in which strong water vapour, dust or smoke arise under normal conditions, alarms may be triggered due to the scattered-light principle because of unfavourable environmental factors, e.g. dust, condensed water or draught air. It is possible in these rooms to switch off smoke detection of the smoke alarm device. The smoke alarm device then only operates as a heat detector.
