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.

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.

2 Design Reference
When designing, select the specifications of the linear cable heat detector
according to the ambient mounting environment. Generally, select the rated action
temperature, if the highest temperature is above 30 in mounting place.℃The
interface with the first end of the heat cable enclosed should be located where the
detector is. Wiring of the heat cables should be referred to the characters of the
protected subject to make it in best condition. And the terminal should be far from
the electromagnetic field.

(1) The address number of the interface should be programmed by hand held
programmer by project’s request before it is used to the system. The interface
is defaulted two loop, so it has two address numbers-- ×× and ×× +1. If the
address number is required to change, modify the address number of Loop I ，
and that of Loop II will be added to 1 automatically.
(2) When there only needs one heat cable, change the device type of the interface
from 8 to 18. See Hand Held Programmer Installation and Operation Manual
for details.
(3) After wiring and installation, power on the fire alarm control panel and enter
system commission state. First check whether all the interfaces registered and
write unregistered interface down to find faults. As for the registered interfaces,
they are defined as linear heat cable with device type 8 through fire alarm
control panel. See Fire Alarm Control Panel Installation and Operation Manual
for the specific definitions.
(4) All the interfaces, other detectors, modules are registered, power on the
system and make it in normal condition. At the time, the interface should not
report fault or alarm.
(5) The detector is made up of the interface, the terminal and heat cable. Fig. 14
shows its system composition.
VII Testing
Instructions: After installation and commission, register the devices through the fire
alarm control panel then check whether all the interfaces registered and write
unregistered interface down to find faults. As for the registered interfaces, make
simulation and manual fire test. When short condition occurs to the heat cable, the
address number of related interface will transmit such a status to the fire alarm control
panel which generates fire alarms.
1. Before testing, notify the proper authorities that the system is going to be
maintenance and out of service temporarily. Disable the zone or system
undergoing maintenance to avoid unwanted alarms.
2. Manual Fire Test: Remove the commission tool, put its Commission Zone close to
Fire Test position on the upper part of the terminal. Check whether the red LED is lit.
Remove the commission tool to clear fire condition, the system goes back in normal
monitoring state. Fig. 15 shows the fire test.

40s. Before testing, 3m～5m lengthened heat cable should be reserved for test.
4. Cut the cable which is put in the water and connect the terminal again, the system
will reset to the normal monitoring state
5. Check its wiring again when an interface fails to the test, then test it once more. If it
still fails, please return it for repair.
VIII Troubleshooting
1 Registration Fault: When registering the detector on fire alarm control panel, if
some interfaces cannot be registered, repair according to the following steps.
（1） Read the code by hand held programmer. Check the address number,
device type, to see whether they meet the design requirement or the code is
repeated. If the programmer fails to read codes, so it’s certain that there are
problems with the interface. If there is no problem with the address number and
device type, check the loop voltage and impedance, see if there is circuit fault.
（2） For the interface with fault, please contact local office of GST or GST
Company.
2 The interface gives fault: When the FACP is in normal monitoring state, if the fault
occurs on the interface, repair by the following steps.
（1） When the FACP is on, check the yellow Fault LED, if lit, there is fault on
the heat cable or its testing circuit and the terminal. If the Fault LED is not on,
press “Clear” on the FACP to see if the Red LED flashes when polling, if the Red
LED stops flashing, there is fault on the interface.
（2） Turn off the FACP. As for the interface with fault on the heat cable and the
terminal, check if circuit of the heat cable is open and check the resistor
between two connection poles. If it is 10KΩ, it is normal; if infinite, the terminal is
damaged.
（3） If there is not open circuit on the heat cable and the terminal after
checking, the interface is in trouble, please return it for repair.
3 The interface gives false alarm: When the FACP is in normal monitoring state, if the
interface of the detector alarms falsely, repair by the following steps.
（1） Turn off the FACP: First separate the heat cable and the terminal. Check if
their circuits are shorted separately. If the short circuit occurs to the terminal,
check the internal components; if the short circuit occurs to the heat cable,
please repair the heat cable.
（2） If short circuit is found on neither heat cable nor the terminal, please
return the interface for repair.
IX Maintenance
Measure the insulating resistor with 500VMΩmeter between the two-core cables every
half year. The resistance should be over 500MΩ( turn off the power and disconnect the
two ends of the heat cable when testing). If the value is below 500MΩ, replace the heat
cable.

1 Each loop should be tested once every year for manual fire alarm or simulation fire
alarm.
2 Every five years, each time should be made bulge test without breakage. If there is
breakage, replace the heat cable.
3 Check damage of the heat cable irregularly and take measures for those with
damaged outer sheathing.
X Cautions
1 The interface is defaulted double loop (device type is 8), which can be connected
with two heat cables. When one heat cable is required, the interface should be set
single one（device type is 18）. The cable heat can connect with any loop of terminals.
2 The enclosure of the fire alarm control panel should be grounded. When the
interface and the terminal are mounted indoors, fix them on the wall or metal bracket in
field. When mounted in open air, add rain-proof enclosure.
3 The heat cable mustn‘t be curved forcedly or twisted when mounting. Curve radius
of the heat cable should be over 15cm. Protect the sheathing against damage. And
package it properly to avoid squeeze.
4 The detector should be stored in the ventilation rooms where ambient temperature
is 0℃～45℃, with relative humidity 75%.
5 The interface should be mounted far away from strong electromagnetic zone. If the
loops are not galvanized, they must adopt shielded cable, with its shielded layer
connected with ground through earth terminal inside the interface. The interface has two
pairs of terminals for loops inside so that the loops can be divided inside the interface.
Connect with ground at dividing point to make sure Uniformity and continuity.
6 The terminal should be mounted away from strong electromagnetic field.
