Function
The wireless module GC 171 makes wireless communication possible
between the lintel-mounted smoke switch GC 151 and various wireless
devices (wireless smoke detector GC 172, wireless thermal detector GC
173 and wireless input module GC 175).
The wireless module GC 171 forwards wireless signals to the lintel-
mounted smoke switch GC 151 as changes in resistance. These changes
in resistance correspond to those of the ceiling-mounted detectors GC
152 and GC 153 and the manual trigger switch.
An alarm triggered at a wireless module is indicated without delay (in less
than 10 s) at the lintel-mounted smoke switch GC 151.
Interference with a wireless device or a problem with communication
is indicated in less than 100 s on the lintel-mounted smoke switch GC 151.
Number of wireless participants
The wireless module GC 171 can communicate with a maximum of 6
wireless devices (GC 172, GC 173 or GC 175).
