30305302 Issue 3.02
Features
Twin LED for 360°view.
Built-in microprocessor selects and processes
data in real time.
Rate of rise and fixed temperature alarm modes.
Remote indicator output available.
Designed to comply with EN 54-5 standard.
Description
C-9103(Ex) Explosion Proof Rate of Rise and Fixed
Temperature Heat Detector is non-addressable.
Built-in microprocessor, it works stably with reliable
fixed fire judging program, applicable to Zone I and
Zone II in petrol and chemistry industries. Used
together with I-9332 interface, it can be connected
with compatible FACP (fire alarm control panel) to
process fire alarm signals. When checking the fire
signal, the detector transmits it to the interface by
changing its own current and shows fire alarm
condition by lighting indicator until it’s reset.

There are four terminals with numbers on the base.
1: Detection zone positive IN
2: Detection zone positive OUT
3. Detection zone negative IN and OUT
2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Cabling
1.0mm2 or above fire cable, the capacitance
distributed among cables should not be over 0.04μF,
and the inductance distributed should not be over
4.3mH. Subject to local codes.
Installation
A fixed installation direction is ensured by the location
elements on the detector and the base. Fix the base
with two tapping screws, and then align mark C on the
detector with Aon the base, rotate the detector to align
mark C with mark B (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the
base.
Fig. 3 shows the installation of the detector.
Note: The detector shall be horizontally installed. If
it has to be installed on an inclined plane, the
inclination angle shall not be over 45º.

Application
Warning: The detector should be connected with
fire alarm control panel or other devices with
current limit function. Otherwise the detector may
be damaged by too heavy alarm current.
The intrinsically safe fire system is made up of C-9103
(Ex) detector, FACP, I-9332 Interface, C-9101(Ex)
Explosion Proof Combination Heat/Photoelectric
Smoke Detector, C-9201 (Ex) Manual call point and
4.7kΩ end-of-line resistor. Fig. 4 shows the system
connection.

NOTES:
1. The interface can connect up to 10 explosion
proof products.
2. During maintenance, products passing the
explosion-proof test should not be replaced and
parts and structure affecting explosion-proof
functions should not be modified.
