2 Short Information
The RF fire detection system consists of 1 FK 100 RF Interface Module and up to 30 RF smoke
detectors (DOW 1171 RF Smoke Detector and/or SMF121 RF Manual Call Point). As an LSN
element, FK 100 RF Interface Module is switched in a loop or stub line and forms the interface
between the RF smoke detectors and the fire panel.
Transfer of information between detector and interface module is bi-directional. If a base
channel is occupied by an external system, the system immediately switches to a secondary
channel to guarantee alarm transmission.
The RF fire detection system works in a frequency range of 868 to 870 MHz. Within this range,
a few channels are exclusively defined for radio applications in security systems. This
guarantees an extremely high level of operational stability.
