2.5 Battery replacement
The wireless detector signals "Low battery charge" to the wireless module GC 171 if the charge state of the batteries is no longer suf-
ficient. Both batteries (main battery and slave battery) always have to be replaced together. The set-up switch for the wireless detector
must not be activated.
X 1. Take the wireless detector from the base.
X 2. Use a small screwdriver to remove the battery compartment cover.
X 3. Remove the main battery.
X 4. Use a small screwdriver to carefully remove the slave battery.
Ensure that the PCB does not become damaged.
X 5. Slide the new slave battery (type CR2032A) into place – the positive pole faces upwards.
X 6. Insert the new main battery (type CR123A) – make sure polarity is correct.
X 7. Replace the battery compartment cover.
X 8. Insert the wireless detector into the base.
X
9. Test the wireless detector. It can take up to a minute for the wireless detector to be
ready for operation after battery replacement.
2.6 Connect the wireless ceiling-mounted smoke detector GC 172 to wireless module GC 171
Set up a new wireless connection
A maximum of 6 wireless connections can be set up at one wireless module GC 171:
X
1. All the wireless device switches of the wireless module GC 171 are in
the OFF position.
X
2. The set-up switch of the new wireless detector is set to the ON position.
X
3. The protective film is on the battery compartment of the new wire-
less detector and the main battery for the new wireless detector has
not been fitted
X
4. Switch the supply voltage for the wireless module GC 171 on. The
wireless module is in "operating" mode.
X
5. Press the PB1 push button on the wireless module GC 171 briefly to
change to the "set up wireless connection" mode. The status LED2 of
the wireless module GC 171 is now permanently lit red.
X
6. Slide a free wireless device switch SW1x of the wireless module GC
171 to the ON position. The corresponding wireless device LED1x starts
to flash green. If a connection has already been set up for the wireless
device switch selected, this is overwritten by the following process.
The wireless module GC 171 waits for the connection query for a new
wireless device. If a new wireless device does not respond within 2
minutes, the wireless module GC 171 cancels the connection attempt,
the corresponding wireless device LED1x lights up red. To start the con-
nection attempt again, slide the corresponding wireless device switch
SW1x to the OFF position briefly, then slide it back into the ON position.
The corresponding wireless device LED1x now flashes green again for 2
minutes.
X
7. Remove the protective film from the battery compartment of the new
wireless detector and install the main battery in the new wireless detec-
tor. Make sure of correct polarity.
The LEDs of the new wireless ceiling-mounted detector flash green
twice first, then light up yellow for one second and then flash
times. As soon as the LED goes out after that, the connection can be
set up.
X
8. Now slide the set-up switch on the new wireless detector to the OFF
position. After a short time, the LED of the new wireless detector will
flash green for a few seconds. The corresponding wireless device LED1x
of the wireless module GC 171 lights up green permanently.

X
9. If the LED on the new wireless detector lights up red permanently, no
connection has been made. In this case, remove the main battery from
the new wireless detector, slide the set-up switch on the new wireless
detector back and forward 6 times and start again with step 7.
X
10. Fit the wireless ceiling-mounted detector to the base.
X
11. Slide the wireless device switch SW1x of the wireless module GC
171 to the OFF position again. The colour the corresponding wireless
device LED1x flashes indicates the quality of the wireless connection
(see connection quality). Optimise the quality of the wireless connec-
tion if necessary by changing the position of the wireless detector.
X
12. The connection of the wireless module GC 171 to the new wireless
detector has been set up.
X
Note the set-up connection (the number of the assigned wireless de-
vice switch) onto the identification plate of the new wireless detector.
X
To set up further wireless connections, continue with step 6.
X 13. Press the PB1 push button on the wireless module GC 171 briefly
PB1
to change to the "operating" mode. The status LED2 of the wireless
module GC 171 goes off.
