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 specications.
úOnly appropriately qualied people may carry
out installation, commissioning and maintenance.
Unauthorised modications 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-specic regulations.
úProtect the components of the GC173 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 GC172 ID 195522
úWireless ceiling-mounted thermal detector GC173 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 Technical data
Wireless ceiling-mounted thermal
detector GC173 comprising: ID 195523
úBase GC170 B
úWireless thermal detector GC003 F
úTwo batteries
Battery type CR 123A (3 V DC)
Colour White, RAL 9016
Dimensions (with base, Ø × H) 110 mm × 65 mm
Functional principle Alarm if the ambient temperature exceeds the alarm temperature or if the ambient temperature
increases very quickly, no alarm saving (self-resetting as soon as the ambient temperature has
dropped again)
Alarm temperature 57°C
EN 54-5 classication A1R
Installation position Ceiling mounting
IP rating (in accordance with EN
60529) IP20, only for dry areas
Relative humidity 95% (non-condensing)
Ambient temperature -10 °C to 55 °C
Detector test To activate test mode:
XMove the test magnet near to the magnetic sensor (GEZE logo).
The LED ashes green.
Alarm triggering:
XMove the test magnet near to the magnetic sensor (GEZE logo) again.
XTrigger the alarm using the heat detector testing device.
The detector test using a test magnet tests the electrical components. The detector test which
forms part of the regular testing of the hold-open system must be carried out using a heat
detector testing device.

3 Wireless ceiling-mounted thermal
detector GC173
3.1 Use
The GC173 is a wireless ceiling-mounted thermal detector for
use in the GEZE hold-open system FA GC150 or FAGC160.
Signal transfer from the detector takes place wirelessly.
A wireless module GC171 is essential for use of the
wireless ceiling-mounted thermal detector GC173.
Thermal detectors measure the ambient temperature and
respond if the temperature exceeds a certain maximum
value or increases quickly within a certain time.
Usually, smoke and re gases spread quickly when a re
breaks out. It is only later that the temperature increases.
As far as possible, smoke detectors should generally be
used for hold-open systems. In areas where disruption such
as steam, dust, condensation or operation-related smoke
development (workshops, kitchens) occurs, it may, however,
be sensible to use thermal detectors rather than smoke
detectors.

Smoke detectors must be used for hold-
open systems for closers on rescue routes.

operation and maintenance - see www.geze.com.
