2 Wireless ceiling-mounted smoke
detector GC 172
2.1 Use
The GC 172 is a wireless ceiling-mounted smoke detector for
use in the GEZE hold-open system FA GC 150 or FA GC 160.
Signal transfer from the detector takes place wirelessly. .
A wireless module GC 171 is essential for use of the wire-
less ceiling-mounted smoke detector GC 172.
Smoke detectors detect smoke. They work using the light
scatter principle. A light transmitter and a light receiver
are arranged in the measuring chamber in such a way that
no light meets the receiver in the normal case. If there are
suspended particles (smoke) in the measuring chamber,
these scatter part of the light onto the receiver, which

converts this into an electric signal.
In other words, a smoke detector not only detects smoke
but all other suspended particles and responds sensitively
to soiling.
2.2 Protection of the smoke detector from
soiling
àDo not remove the dust protection cap from the smoke
detector until commissioning is about to take place.
àAfter the smoke detector has been installed and the
dust protection removed, make sure no dust gets into
the measuring chamber. This leads to increased soiling
and can signicantly shorten the service life of the
smoke detector.
àThe measuring chamber of a smoke detector must not
be opened.

X7. Remove the protective lm 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 ash green
twice rst, then light up yellow for one second and then ash red four
times. As soon as the LED goes out after that, the connection can be
set up.
X8. 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
ash green for a few seconds. The corresponding wireless device LED1x
of the wireless module GC 171 lights up green permanently.
X9. 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.
X10. Fit the wireless ceiling-mounted detector to the base.
X11. Slide the wireless device switch SW1x of the wireless module GC
171 to the OFF position again. The colour the corresponding wireless
device LED1x ashes 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.

X12. The connection of the wireless module GC 171 to the new wireless
detector has been set up.
XNote the set-up connection (the number of the assigned wireless de-
vice switch) onto the identication plate of the new wireless detector.
XTo set up further wireless connections, continue with step 6.
X13. Press the PB1 push button on the wireless module GC 171 briey
to change to the “operating” mode. The status LED2 of the wireless

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-
cient. 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.
X1. Take the wireless detector from the base.
X2. Use a small screwdriver to remove the battery compartment cover.
X3. Remove the main battery.
X4. Use a small screwdriver to carefully remove the slave battery.
Ensure that the PCB does not become damaged.
X5. Slide the new slave battery (type CR2032A) into place – the positive pole faces upwards.
X6. Insert the new main battery (type CR123A) – make sure polarity is correct.
X7. Replace the battery compartment cover.
X8. Insert the wireless detector into the base.
X9. 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:
X1. All the wireless device switches of the wireless module GC 171 are in
the OFF position. SW1x
X2. The set-up switch of the new wireless detector is set to the ON position.
X3. The protective lm is on the battery compartment of the new wire-
less detector and the main battery for the new wireless detector has
not been tted
X4. Switch the supply voltage for the wireless module GC 171 on. The
wireless module is in “operating” mode.
X5. Press the PB1 push button on the wireless module GC 171 briey to
change to the “set up wireless connection” mode. The status LED2 of
the wireless module GC 171 is now permanently lit red.

X6. Slide a free wireless device switch SW1x of the wireless module GC
171 to the ON position. The corresponding wireless device LED1x starts
to ash 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 briey, then slide it back into the ON position.
The corresponding wireless device LED1x now ashes green again for 2
minutes.
