I General
I-9106 Intelligent Linear Cable Heat Detector （the detector）consists of I-9106
Intelligent Linear Cable Heat Detector Interface（the interface）, P-9106 Intelligent
Linear Cable Heat Detector Terminal (the terminal) and series linear heat cables. It is a
fixed temperature detector well designed and developed by GST, with the features of
easy mounting and stable operating.
The detector is linear heat detector, especially used to predict an early fire occurring to
power cable and control cable in tunnels. It is applicable to power plants, transformer
substations, steel mills, chemical factories and ancient buildings.
II Features
1. Stable structure, strong stretching resistance and vibration resistance.
2. It has the privilege in the adverse conditions such as damp, dust, oil and corrosive
gas exist while other type of detectors cannot be applied.
3. With good anti-interference ability, grounding measures, isolation test and software
anti-interference techniques , the detector can be used to the place where affected
by the strong electromagnetic field.
4. The detector can work normally when its loop is extended up to 1km. The heat
cable can be lengthened to 400m and work normally, which is applicable to indoors,
outdoors, acid-proof and explosion-proof places.
5. The fire and fault conditions can be transmitted to the fire alarm control panel
through non-polarized two loop.
6. Optional Single/Double Loop: The interface can connect with two heat cables. If
only one heat cable is needed in the field, the single loop can be set by hand held
programmer.

2 Operation Principle
The interface has a built-in microprocessor and be programmed electronically. It can
connect the detector to fire alarm system through signal two loops. Each interface can
connect with two heat cables, with the first end of the heat cable connected with the
interface and the last end connected with the terminal. Each loop of the heat cable
occupies one address point.
The linear heat cable is a part of sensor component in a field fire alarm system. The heat
cable is made up of two twisted flexible steel wires. Each wire is coated with isolation
material. In normal monitoring state, the resistance of each steel wire is indefinite, and
the heat cable has a tiny standby current because of the terminal resistance. When the
ambient temperature rise up to rated action temperature, the isolation material between
the steel wires melted, which make the two twisted wires shorted on a certain point. At
the time, the standby current in the heat cable will be increased, the interface will check
such a change and transmit it to the fire alarm control panel.
The terminal is a special accessory, connected to the end of the heat cable without
connecting with fire alarm control panel. The terminal has fire test device, convenient for
simulation fire test on the detector.
V Mounting and Wiring
Wiring: Please disconnect the power of the loop before installing the devices.
1 The Interface
(1) There are ways to mount the interface. One is wall-mounted, the other is
rack-mounted.
a. Fix the interface to the wall with two M6×60 expansion bolts. Top view of the
mounting is shown in Fig. 3.

The wiring procedure of the interface:
Before wiring, take off the six bolts and remove the cover.
Put the heat cable in the cable socket, and connect to the corresponding
terminals.
Put on the cover.
Screw the cover securely.
There are two cable sockets on the top and bottom of the interface. These two

cable sockets on the top are to connect with loops, those ones on the bottom with
heat cable. When the interface connects with incomings and outgoings, remove the
waterproof plug, replaced with spare cable socket to connect with another pair of
loops.
Z1, Z2, Z3 and Z4 adopts copper core cable thread with cross section not less
than 1.0mm2 andexternal diameter ∅8mm～∅10mm. The product needs the cable
with ∅8mm～∅10mm to meet the requirement of water-proof. We advise not to
use twisted pair or solid wire. It they have to be used, please enwind those part
which is to go through the interface to ∅8mm～∅10mm rude material belt.
2 The terminal
The terminal can be fixed to the cable support rack with ∅6 plastic expansion bolts
（See Fig. 6）. Mounting hole spacing is 95mm.

3 Linear Heat Cable
There are three methods for cable heat wiring: Line type, cycle type and similar sine
wave type.
（1） Mounting below the ceiling
When the heat cable is mounted Indoors, its distance from the ceiling or side
wall should not be more than 0.5m ( 0.2m～0.3m is acceptable), shown in
Fig. 8.

（2） Mounting on the cable tray or support rack
When the heat cable is mounted on the cable tray or support rack, it should be
mounted on the protection cover of monitored power cable and control cable,
adopting contact mounting as much as possible. Fig. 10 shows the specific
mounting.

should be made according to Table 1).

When the heat cable is mounted on the power cable in sane wave type, the
number of retaining clip can be calculated by the formula:
The number of retaining clip＝The number of half sine wave×2＋1
（3） Mounting on the conveyer
There are two designs.
If the conveyer’s width is not over 3m, it can be protected by a heat cable as long
as the conveyer. The heat cable should be fixed to the appurtenance where
locates 2.25m over the conveyer center. The appurtenance can be a supporting
wire or any existing fixings. The supporting wire can provide a strutting piece and
it can be tightened by a screw every 75m. In order to prevent the heat cable falling,
firmly clip the supporting wire and heat cable every 4m～5m with a fastener. It’s
recommended that the supporting wire be aφ2 stainless steel rope, each not be
over 150m long (galvanized steel ropes can be used as a replacement ). The
mounting method is shown in Fig. 11.

The heat cable can be mounted on the two sides of the conveyer. Connect the
heat cable through heat-conductive board and roller bearing to detect over-heat
because of bearing friction and coal powder accumulating. Please install it
according to the field situation but do not affect operation and maintenance.
Mounting is shown in Fig. 12.

（4） Mounting on the Power Control Equipment
Take the heat cable mounting on the dynamo panel as an example. The whole
devices can be secured by reliable string prick. In case the ambient temperature
is suitable for the heat cable, transformer, switch, and main power distribution
device resistors can be mounted by the same method. See Fig. 13.

municipal facilities and high warehouse. Its mounting method can be the same
as mounting under the ceiling. When mounting near or contacting the protected
device, refer to mounting in cable tray.
