Fire Safety & Security Systems
With the radio gateway it is possible to monitor signals emitted by radio detectors
and to send them to a fire control panel via the FDnet.
The radio gateway is operated on the FDnet. The term "Radio detectors"
comprises all devices that can be monitored by the radio gateway.
The radio gateway FDCW221 may communicate with the following radio detectors:
Radio smoke detector DOW1171
Manual call point with radio base SMF6120
A radio cell is made up of a radio gateway and the radio detectors registered on it.
The following figure shows how the radio gateway is integrated into the fire
