7. Features and functions
The ‘RM 100-2 Uni-S’ smoke detector registers smoke emissions (smouldering fires and open
fires with smoke emissions) optically using the scattered light principle.
When the smoke concentration reaches a specific level, the smoke detector activates the
integrated signal transmitter. A red warning LED is also activated as well as a white LED, which
serves as an emergency light.
A smoke alarm is simultaneously transmitted to an existing ‘HMS 100 Z’ central unit belonging
to the ‘HMS 100’ hazard detection system or the ‘FHZ 1000’ home radio central unit.
This ensures that a fire, which is some distance away (on another floor of the
house, for example), can be responded to in good time.
Furthermore, several smoke detectors in the ‘RM 100’ series can be connected by cable,
allowing the smoke alarm to be relayed by cable.
This allows rooms to be monitored whose current conditions make radio
monitoring technically difficult.
In order to avoid crossovers with other radio services operating on the 868 MHz frequency
band, the system can be coded using a house code. This protects the system from false alarms
caused by other radio transmitters operating in the same frequency range.
