Description
DC-9103 Innovation Dual 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 bottom is shown in Fig. 1 and the base in Fig. 2.

Fig. 1 Fig. 2
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 Wiring
1.0mm2 or above fire cable for all terminals laid through metal
conduit or flame retardant conduit, subject to local codes.
Note: It’s recommended to use cables of different colors to
avoid incorrect wiring.
Installation
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. 3.

Application
Warning: The alarm current depends on the current limit of
the FACP. 24VDC power cannot be applied to the detector
directly. Otherwise the detector may be damaged for lack of
current- limit resistor.
The default class of the detector is A1R, 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 (“2”for A1R, “3”for
A2S) 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.
The detector is especially applicable to places where fire occurs
with a sharp rise of temperature. Used together with smoke
detectors, it can help to increase the reliability of fire detection
thus reducing losses.
When the detector is connected with compatible FACP or
addressable zone monitor unit in series, if DP-9907 Active
End of Line Unit (AEOL) is connected to the end of output loop,
a DB-01D base should be used.
If the AEOL is used as the detector base, a conventional
detector can be installed on it. The system composition is
shown in Fig. 4.
Fig. 4
When the AEOL is not used as the detector base, a cover
should be put on it. The system composition is shown in
Fig. 5.

When the detector is connected with conventional FACP or
addressable zone monitor unit, if a 4.7kΩend of line resistor is
connected to the end of output loop, DB-01 base is used. The
system composition is shown in Fig. 6.

When multiple detectors are connected with a remote
indicator, a diode 1N5819 should be connected to Terminal 4
of the orientation base in series before going to the positive
of the remote indicator. System composition is shown in Fig.
8.
Fig. 7
Maximum 15 detectors can be connected to the output of zone
monitor unit. In case of broken circuit or removal of any detector,
the unit will transmit a fault message to the FACP. If and AEOL is
connected, normal operation of other device in the system will not
be affected.
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.
The detector must be tested
after installation and regular
maintenance. The methods are
as follows:
(1)Reed switch testing
The testing area of the detector
is shown in Fig. 4.
Approach thecommission 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) to the thermistor of the
detector until it alarms.
After testing, disconnect power to the detector for over 5 seconds
to reset it. Notify the proper authorities that the system is back to
normal operation.
If adetector fails in testing, clean it by the steps in “Maintenance”,
and retest it. If it still fails, return it for repair.
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.
Clean the detector at least once a year to ensure normal
operation of the system.
Before cleaning, 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 should be tested again after cleaning and
re-installing.
Protect the metal component on the PCB against damp and
improper distortion.
Do fire simulation test at least once every 6 months.
