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 classification
A1R
Installation position Ceiling
mounting
IP rating (in accordance with EN 60529)
IP20, only for dry areas
Ambient temperature
-5°C to 50°C
Detector test
Alarm actuation
- using test magnet near the magnetic sensor (GEZE logo)
- with 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.

Wireless ceiling-mounted thermal
detector GC 173
2.1 Use
The GC 173 is a wireless ceiling-mounted thermal 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 thermal detector GC 172.
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 fire gases spread quickly when a fire
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 or operationally caused 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 system doors
on escape routes.
Heed the document for the hold-open system FA GC 150
or FA GC 160 - Instructions for the installation, commis-
sioning, operation and maintenance, see www.geze.com.
