Description
DC-M9103 Conventional Rate of Rise and Fixed
Temperature Heat Detector is a new generation
product of GST. With built-in microprocessor, it works
stably by being fixed with highly reliable fire judging
program.
On detecting a fire signal, it can change its own
current to transmit the signal to fire alarm control panel
(FACP) or addressable zone monitor unit. The
detector keeps illuminating fire LED until it is reset by
power-down.
Connection and Wiring
The detector connects with UL-certified products such
as modules and control panels. The detector bottom is
shown in Fig. 1 and the base in Fig. 2.
Fig. 1 Fig. 2
Please install the base according to following steps:
1) Locate mounting holes on the rubber layer of the
base according to the holes on the back box, and
punch the holes with a screwdriver.
2) Count the number of cables needed and punch
correct quantity of holes with a screwdriver on
the rubber layer. Thread the cables through the
cable entry holes.
3) Install the base onto the back box with screws.
Warning: Do not punch mounting holes and cable
entry holes bigger than needed. Do not punch
more holes than needed.
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
It connects a 4.7k/1w resistor between number 2
and 3 at the end of the base. The system
connection is shown in Fig. 3.

Recommended Wiring
1.0mm2or above fire cable for all terminals laid through
metal conduit or flameretardant conduit, subject to local
codes.
I-M9300 modules connect with 15 conventional devices
at most.
Note: It’s recommended to use cables of different
colors to avoid incorrect wiring.
Installation
Refer to D Series Detector Application Bulletin for
additional installation instructions.
First fix the orientation base with two tapping screws.
Then align A(Fig. 1) on the bottom of the detector to B
(Fig. 2) of the base, and rotate the detector clockwise
to mark C.
Mounting of the detector is shown in Fig. 4.

Application
Warning: The alarm current depends on the
current limit of the control panel. 24VDC cannot
power the detector directly. Otherwise the detector
will be blown up for lack of current limit resistor.
The default class of the detector is rate of rise and
fixed temperature, which can be modified using GST
handheld programmer.
When the programmer is in standby state, entering
unlock password and pressing “Clear”, it will be
unlocked. Pressing Function followed by 4, there will
be a “-”at the last digit. Entering different number
corresponding to the classes (“7”for rate of rise and
fixed temperature, “8”for fixed temperature) followed
by “Program”, there will be a “P”shown on the screen,
indicating its class is programmed. Pressing “Clear”
can clear the “P”, and entering locking password
followed by “Clear”will exit.
Read Heat Detector Class: When the programmer is
in standby state, pressing “Test”, it will display address
of the detector. Pressing “Up”, it will display sensitivity
level, device type and heat detector class in turn.
Testing
Note: Before testing, make sure the detector is
properly installed and powered up. Testing can
only begin after the detector is powered up for 10
seconds.
Before testing, notify the proper authorities that the
system is undergoing maintenance and will
temporarily be out of service. Disable the zone or
system undergoing maintenance to avoid unwanted
alarms
The detector must be tested after installation and
regular maintenance. The methods should meet the
requirements from local authority. The detector should
meet NFPA72. The testing methods are as follows:

(1) Reed switch testing
The testing area of the detector is shown in Fig. 5.
Approach the commission tool to the testing area of
the detector and hold for several seconds until the
detector alarms.

(2) Temperature test
Approach a heater (such as a hair drier of
1000w-1500w) to the thermistor of the detector until it
alarms. It is 12 inches between the hair drier and the
thermistor to avoid damaging on the plastic enclosure
of the detector
After testing, disconnect power of the detector for over
10 seconds and then reset it. Notify the proper
authorities that the system is back to normal
operation.
Maintenance
The detector should be installed just before
commission and kept well before installation, taken
corresponding measures for dust-proof,
damp-proof and corrosion-proof.
The dust cover cannot be removed until the project
has been plunged into usage.
Do fire simulation test at least once every 6
months.
Before fire simulation test, notify the proper
authorities that the system is undergoing
maintenance and will temporarily be out of service.
Disable the zone or system undergoing
maintenance to avoid unwanted alarms.
Protect the metal component on the PCB against
damp and improper distortion.
Cautions
1. Detector should be firmly installed and the wire
be reliable.
2. LED on the detector should face the main
entrance for people to see it.
3. Be careful not to damage the detector in
maintenance.
4. Heat detector is not suitable for detecting
smoldering fire.
