1 Safety instructions
To ensure personal safety, it is important to follow these
safety instructions. These instructions must be kept.
úBefore installation, read and observe the safety notes
for these components and the drive. Warranty claims
require proper mounting, installation and maintenance in
accordance with the manufacturer's specications.
úOnly appropriately qualied people may carry
out installation, commissioning and maintenance.
Unauthorised modications to the system release GEZE
from liability for any resulting damages.
úOnly use GEZE original parts for repair and service work.
úObserve the latest versions of guidelines, standards and
country-specic regulations.
úProtect the components of the GC172 from construction
dirt and water.
2 Brief description of wireless kit
The wireless kit is part of the GEZE hold-open system FA
GC150 or FA GC160.
The wireless module GC 171, ID 163051, makes wireless com-
munication possible between the lintel-mounted smoke
switch and the various wireless devices:
úWireless ceiling-mounted smoke detector GC172 ID 195522
úWireless ceiling-mounted thermal detector GC173 ID 195523
úWireless input module GC175, ID 163068 (for the connection of
manual trigger switches or contacts for the re alarm system)
3.2 Protection of the smoke detector from contamination
úDo not remove the dust protection cap from the smoke detector until commissioning is about to take place.
úAfter the smoke detector has been installed and the dust protection removed, make sure no dust gets into the measuring chamber.
This leads to increased contamination and can signicantly shorten the service life of the smoke detector.
úThe measuring chamber of a smoke detector must not be opened.
Heed the document for the hold-open system FA GC150 or FA GC160 - Instructions for the installation, commissioning, operation and
maintenance, see www.geze.com.

3.1 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
wireless ceiling-mounted smoke detector GC172.
Smoke detectors detect smoke. They work using the scat-
tered light principle. A light transmitter and a light interface
are arranged in the measuring chamber in such a way that
no light reaches the interface in the normal case. If there are
suspended particles (smoke) in the measuring chamber, these
scatter part of the light onto the interface, 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 contamination.

Set up wireless connection
XSlide 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 pro-
cess. 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.
XTo start the connection 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.

Install batteries
XRemove the protective lms from the battery compartment (4) of the new wireless detec-
tor and install the batteries (5) in the new wireless detector. Make sure of correct polarity.


The LED (2) on the new wireless ceiling-mounted detector ashes green twice rst, then
lights up orange for one second and then ashes red four times.
As soon as the LED (2) goes out after that, the connection can be set up.

XSlide the set-up switch (6) on the new wireless detector to the 1 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.

If the LED (2) on the new wireless detector lights up red permanently, no connection has
been made.
XIn this case, remove the batteries from the new wireless detector, slide the set-up
switch (6) on the new wireless detector back and forward six times and install the bat-
teries (5) again. Continue as described above.
XFit the wireless ceiling-mounted smoke detector to the base (8).
XSlide 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).
XOptimise the quality of the wireless connection if necessary by changing the
position of the wireless detector.

SW1x
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 device switch)
onto the identication plate of the new wireless detector.
XTo set up further wireless connections, continue with step “Set up wireless connection”.
XPress the PB1 push button on the wireless module GC171 briey to change to the
“operating” mode.
The status LED2 of the wireless module GC171 goes o.

3.5 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
sucient. Both batteries (5) always have to be replaced together. The set-up switch (6) for the wireless detector must not be activated.
XTake the wireless detector out of the base (8).
XRemove the battery compartment cover (3).
XRemove both batteries (5).
XInsert new batteries (type CR123A) – make sure polarity is correct.
XReplace the battery compartment cover (3).
XInsert the wireless detector into the base (8).
XTest the wireless detector. It can take up to a minute for the wireless detector to be ready for operation after battery replacement.
3.6 Connecting the wireless ceiling-mounted smoke detector GC172 to wireless module GC171
A maximum of 6 wireless connections can be set up at one wireless module GC171.
