Wireless module GC 171
2.1 Use
The wireless module GC 171 is connected to the lintel-mounted smoke switch. An alarm triggered at a wireless module is indicated
immediately at the lintel-mounted smoke switch. Interference with a wireless device or a problem with communication is indicated on
the lintel-mounted smoke switch in less than 100 ms.
The wireless module GC 171 forwards wireless signals to the lintel-mounted smoke switch as changes in resistance.

and maintenance, see www.geze.com.

2.5 “Operating” mode
After the supply voltage has been switched on, the wireless module GC 171 is in “operating” mode.
In “operating” mode the wireless module 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 wireless module. The following
table shows the states for the different events:
à
of the wireless device LEDs of the wireless module,
à
of the status LED of the wireless module,
à
of the LED of the lintel-mounted smoke switch,
à
of the hold-open output of the lintel-mounted smoke switch.
The wireless module indicates an event until the cause has been eliminated. If the cause of an event is no longer present, the wireless
module changes back to normal mode (the displays are deleted and 24 V is applied to the hold-open output of the lintel-mounted
smoke switch again).

1) If the LED flashes red 5 x on the lintel-mounted smoke switch GC 161, the 6.8 kΩ resistor has not been connected properly.
Connection quality
If the wireless device switch is in the OFF position during “operating” mode, the corresponding wireless device LED indicates the
connection quality to the corresponding wireless device:
à
LED is off
g
no wireless connection set up
à
LED flashes green every 2 s
g
good connection quality
à
LED flashes yellow every 2 s
g
sufficient connection quality
à
LED flashes red every 2 s
g
still connected but poor connection quality
Connection interference is possible, the quality of the wireless connection should be optimised by changing the position of the
wireless device.
If the wireless device switch is in the OFF position in “operating” mode and the wireless device signals an event (a warning, a fault or an
alarm), the wireless device LED indicates this event in compliance with the table above instead of the connection quality.
General fault
The wireless module signals “general fault” if
à
no wireless connection is set up,
à
the wireless module is in the “set up wireless connection” mode,
à
the set-up switch is in the ON position with GC 172, GC 173 or GC 175,
à
an internal fault has occurred during smoke detection with GC 172
à
the connection between the wireless input module and termination resistor is interrupted with GC 175.
Sabotage
The wireless module signals “sabotage” if a wireless detector GC 172 or GC 173 has been removed from its base.
