Description
DI-9103 Digital Dual Heat Detector is a new
addressable fire alarm device cooperating with GST
intelligent fire alarm control panels(FACP) to build a
fire detection system. The detector shows fire alarm
by the LED indicator and transmits the signal to the
FACP.
Connection and Wiring

There are four terminals with numbers on the base.

2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Wiring
1.0mm2or above fire cable is recommended but
subject to local codes.
Note: It’s recommended to use cables of different
colors to avoid incorrect wiring.
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 A on the
detector with B on the base, rotate the detector to align
mark A with mark C (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the
base.
Fig. 3 shows the schematic for mounting the detector.

Application
The detector is especially applicable to places where
fire occurs with sharp rise of temperature. Used
together with smoke detectors, it can detect fire with
more reliability to reduce losses.
The detector can be addressed in field by using
P-9910B programmer. Please refer to P-9910B Hand
Held Programmer Installation and Operation Manual
for details.
The default class of the detector is A1R, which can be
modified using the 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 the class is programmed.
Pressing “Clear”can clear the “P”, and entering
locking password followed by “Clear”will exit.
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 the commission tool to the testing area of
DI-9103
Digital Dual Heat Detector

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.

(3) After testing, disconnect the power to the detector
for over 5 seconds to reset it. Notify the proper
authorities that the system is back to normal
operation.
(4) If a detector fails in testing, clean it by the steps in
“Maintenance”, and retest it. If it still fails, return it
for repair.
Maintenance
1. The detector should be installed just before
commission and kept well before installation, taken
correspondingmeasures for dust-proof, damp-proof
and corrosion-proof.
2. The dust cover should not be removed until the
project has been plunged into usage. Otherwise it
may not report alarm normally.
3. The detector should be cleaned at least every year
to ensure normal operation of the system.
4. Before cleaning, notify the proper authorities that
the system is under maintenance and will
temporarily be out of service. Disable the automatic
controls relating to the zone or system under
maintenance to avoid unwanted actions.
5. The detector should be tested after cleaned and
re-installed to ensure normal operation.
6. Protect the conductive metal element on the
detector base from humidity or rigid distortion.
7. Fire simulation test should be done to the detector
at least every 6 months.
