GST C-9103 User manual
30301837 Issue 1.05
Features
Built-in microprocessor samples and collects
data in real time.
Rate of rise and fixed temperature alarm mode.
Standard: UL 521.
Description
C-9103(UL) Conventional Rate of Rise and Fixed
Temperature Heat Detector (the detector) is
non-addressable. With built-in microprocessor, it is
fixed with highly reliable fire judging program and
works stably.
When the detector checks fire signal, it can change its
own current to transmit fire signal to control panel or
interface module. The detector keeps illuminating fire
LED to indicate fire status until resetting. Used
together with P-9907 Active End of Line Unit (AEOL),
it can connect with compatible fire alarm control panel
to conduct the processing of detector signals.

The bottom and orientation base of the detector are
shown in Fig.1 and 2. There are four terminals with
numbers on the base, “1” connects with the anode of
the output end of compatible controller, “2” connects
with the power anode of the next detector as output
(terminal No. “1”), “3” connects with the power
cathode of the next detector (terminal No. “3”) and the
cathode of the output end of compatible controller, “4”
doesn’t connect to any wires but is used to fix the
detector accessorily.
Recommended Wiring:
1.0mm2 or above fire cable for all terminals, laid
through metal conduit or flame-proof conduit, subject
to local codes.
Installation
There are location elements on the detector and the
orientation base to ensure there is only one installing
position. There are twomarks on pointA and B of the
orientation base, and a mark on point C of the side
face of bottom of the detector. When installing,
aligning the mark C of the detector to point A of the
orientation base, rotate the detector clockwise to point
B, then the detector is installed.
Mounting of the detector is shown in Fig. 3.

Application
Warning: The detector should be connected with
fire alarm control panel or other devices with
current limit function. Otherwise the detector may
be destroyed by too heavy alarm current.
A 4.7k/1w terminal resistor can be connected
between terminal “2” and “3” of the last base in a loop.
System connection is shown in Fig. 4.

Maintenance
1. Before installation, the detector should be kept well
and adopted the corresponding measures for
dust-proof, damp-proof and corrosion-proof.
2. The dust cover cannot be removed until the project
has been plunged into usage.
3. The detector should be cleaned at least once each
year.
4. Before cleaning, notify relative departments that
the system is undergoing maintenance and will be out

of service. Disable the zone or system in
maintenance to avoid unwanted alarms.
5. After cleaning, install the detector back and test
again. Notify relative departments that the system is
back into operation.
6. Do fire simulation test every half a year to make
sure the detector works normally.
