Technical data
4.5.1 “Operating” mode
After the supply voltage has been switched on, the wireless module GC 171 is in “operating” mode.
LED displays
In “operating” mode the GC 171 monitors the set-up wireless connections and signals faults and alarms to the
lintel-mounted smoke switch. Faults and alarms are also indicated on the status LED and the wireless device LEDs
of the GC 171. The following table shows the states for various events which are signalled via the set-up wireless
connections:
ú
of the wireless device LEDs of the GC 171
ú
of the status LED of the GC 171
ú
of the LED of the lintel-mounted smoke switch GC 151
ú
of the alarm output and the hold-open output of the lintel-mounted smoke switch GC 151
The wireless module GC 171 indicates an event until the cause has been eliminated. If the cause of an event is no
longer present, the wireless module GC 171 changes back to normal operation (the displays are deleted and 24 V is
applied to the hold-open output of the lintel-mounted smoke switch again).
