Description

DI-M9103 Intelligent Rate of Rise and Fixed Temperature Heat
Detector (the 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 condition by
LED indicator and transmits alarm signals to the FACP.

Connection and Wiring

The detector bottom is shown in Fig. 1 and the base in Fig. 2.
Fig. 1
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.

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. 3.

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 rate of rise and fixed temperature
(7) and polling LED is normal. The parameter 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.
