Use
The GC 163 RWA is a heat detector for use in GEZE RWA systems.
Heat detectors measure the ambient temperature and
respond if the temperature exceeds a certain maximum
value or increases quickly within a certain time. These ther-
mal detectors work according to the principle of current
increase. In the event of an alarm, the current consumption
of the detector changes.
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 RWA systems. In areas where disruption such as
steam, dust or operation-related smoke development
(workshops, kitchens) occurs, it may, however, be sensible
to use heat detectors rather than smoke detectors.
Terminating resistor for line monitoring
There must be a 10 kΩ terminating resistor built into the
base GC 160 B of the last smoke detector in a line.
tor is included with the control unit.

Test
Use heat detector testing device from a recognised manufacturer for testing in accordance with the manufacturer's instructions.
à The red LED on the detector must change to the alarm state.
à An alarm must be activated on the RWA control unit.
à After the test has been completed, reset the alarm on the control unit and carry out a detector line reset.
