zINTRODUCTION
In line with technological advanced. Fire alarm systems have become more sophisticated, especially in
developed countries. Likewise, our knowledge and expertise in Fire Alarm Control Panel is also
second-to-none as compared to those produced by developed countries. We have since designed an
Accumulation-type Control Panel that is easy to maintain, aesthetic in outlook and complete with
functions that meet most end-users requirements.
zCHARACTERISTICS
* Up-to-date Designs
(1) Accumulative Capability:
We focus on pulsative waves and interfering signals, which are the most common causes of
false alarm during operation, especially for panels with smoke detector loops. Our panels can
eliminate such phenomenon, minimize the possibilities on false alarm to a very low degree, or
even can completely preventing it from occurring.
(2) Automatic Reset Capability:
When the auto reset button is depressed, it will automatically reset after performs a Detector
Test, in addition to the normal reset function.
(3) Fuse Fault LEDs:
Any failures due to faulty wiring or other causes will be indicated on the panel.
(4) External Indicators:
Our product provides an option for ‘light-on’ or ‘light-off’ in the event of power failures.
Because Fire Indicating Lamp will light up during a power failure, it will easily drain-off the
battery supply and cause the control panel to be in-operative. In the ‘light-off’ mode Fire
Indicating Lamp will remain ‘off’ all the time and only blink during an outbreak of fire, thus
prolonging surveillance capabilities. For ‘light-on’ switch to position (I) and for ‘light-off’
switch to position (O).
(5) Reserve slot for relay output (Optional).
* The Zone Testing Button is located at the Zone Indicator of the control panel. It is self-returning
and can be use to perform test for individual zone.
* Voltage Stabilizer is verified with an applied sudden voltage load. It must pass this test before
leaving the factory for delivery.
* The control panel is made of steel-plate and coated with an attractive oven-baked paint.
* Every zone indicator is made up of two LEDs connected in series and covered with a delicate
glossy light bulb shield (removable plates are included for labeling of different areas).
* Each group of Circuits is detachable for easy maintenance. It also has a one-piece maintenance
Bracket which not only makes the structure of the control panel stronger, but also helps prevent
breakdowns during wiring.
* Zone Testing Button and Relay are tightly sealed from dust, preventing bad connection due to
accumulation of dust.

hand.
(2) Priority should be given to those faulty devices in the area.
(3) Maintenance should be scheduled at least twice a year and must include both physical and
functional inspections.

- 10 -
3. Overall Maintenance
A yearly overall inspection should be carried out by a professional institution, or the Original
Equipment Manufacturer. Inspection records must be tabulated and kept by a responsible person or
the department concerned, to safeguard the public.
(1) Power Supply
Check whether the external wiring of the panel its power consumption are within the safety
regulation, whether the standby power conforms to specifications and whether the duration of
power supply is within the safety regulation.
(2) Control Panel
(A) Fire Test: to check whether the fire alarm system is functioning properly.
(B) Circuit Break Test: to check the whether the “Zone Test” button is functioning properly.
(3) Detectors
To perform a site test for the detectors in order to check whether they are functioning properly and
also to check the condition of detector’s indicating LED (on the detector’s base).
(4) Manual Call Point
To check for integrity of plastic plate, press-down button and condition of wiring inside the MCP.
(5) Insulation Test
The insulation between power terminal of control panel and earth shall have a value of 250V
20MΩand above.
zTROUBLE-SHOOTING
The control panel is produced with an advanced technology and delicate design that is easy to assemble.
It requires no special skills to trouble-shoot a malfunction, thus avoiding any teething problems that might
be encountered during maintenance.
1. Malfunction of Zone Indicator and PBL Combination Panel
The system devices are assembled with many single units (refer page2). Either the ‘Detectors’,
‘Wiring’ or ‘PBL Combination Panel’ is used incorrect, it will affect the function of control panel.
(1) Measure AC power with a Multi-meter for any (AC) voltage. It should read 220V, according to the
specifications of the panel.
(2) Check whether the “Normal Power” Switch inside the control panel is set to “ON” position and the
green color LED Power Light on the power board is lighted up.
(3) Check whether the “AC Power” Indicator and Voltmeter on the panel board are functioning
properly. The system should specify 24VDC.
(4) Check whether fuses are in good condition (or the “AC Power Failure” LED on the Display Board
is lighted up).
(5) Check whether the external devices and wiring conform to specifications, as sated in this
handbook.
2. Functions of Fuse
The panel has six fuses (F1~F6), each with individual protection function. It must not be replaced
with fuses that do not conform to specifications or low quality, otherwise we will not be liable for any
damage. Burnt fuses are probably caused by external wiring error, short circuit or faulty external
devices.

- 11 -
(1) F1: Fuse for alternate power source 24VDC.
(2) F2: Fuse for AC power source 220VAC.
(3) F3: fuse for Stand-by power source.
(4) F4: Extra power source when the need arises.
(5) F5: Fuse for Area Bell.
(6) F6: Fuse for Indicating Lamp in the combination PBL box.
3. Stand-by Power Source In Reverse Order
If the stand-by power polarity is in a reverser order, F3 fuse will be burnt. The polarity should be
immediately corrected.
4. PBL Combination Panel Indicating Lamp and Area Bell Malfunction.
(1) Remove the external wiring of the Indicating Lamp and Area Bell inside the panel.
(2) Measure the (+) outlet of Indicating Lamp with a multi-meter and check whether it reads DC24V.
Then perform a fire test to check for any intermittent power supply. Reset after the test is
completed.
(3) Measure the (+) outlet of the Area Bell with multi-meter. It should not have any voltage supply.
Then perform a fire test and a 24VDC voltage should be recorded. Reset after the test.
(4) When the test results conform to (2) and (3), it indicates that the panel is functioning properly.
The wires should only be connected after the external wiring have been repaired.
5. Zone Indicator Malfunction
Based on our experience, about 90% of the zone indicators’ malfunction is due to incorrect external
wiring. Other factors are mainly due to incorrect handling or incorrect wire joints inside the panel.
6. Blinking of Zone Indicators and “Disconnection” Indicating LED.
When one or several zone indicators and “Disconnection” Indicating LED blink simultaneously, it
should be regarded as a signal of circuit break. In this instance, inspection and repairs should be
carried out in the following manner.
(1) Check for any zones in the control panel are not in use, if yes, check whether the Dip Switch on
the Terminal is in the “ON” position.
(2) Remove the trouble circuit; the disconnection signal should immediately go off.
(3) If test results conform to (2), it indicates that the control panel is functioning properly. The wire
shall only be connected after the external wiring has been repaired.
(4) Inspect the external circuit to check whether last detector has been installed one End of Line
Resistor or improperly installed.
(5) Check for any break in the external wiring as well as any dislocation of Detectors.
(6) Set the multi-meter to Ωmode and measure the malfunction circuit resistance value. The
resistance value between the circuit line and circuit common-line should be 10KΩ.
(7) After removal of the circuit line, there should not be any voltage between the circuit line and
common line. The wire shall only be connected after the external wiring has been repaired.
7. Zone Indicator and “Fire” Alarm Indicator lights Up
When one or many of the zone indicators and “fire” Indicator lights up simultaneously, it should be
regarded as a fire alarm signal. The inspection and repair guidelines are as follows:

- 12 -
(1) Remove the trouble circuit. Measure between the circuit line and common line to check for short
circuit or any resistance value lower than 2KΩ(normal value=10kΩ).
(2) After removal of the trouble circuit line, the panel must be reset. At this moment, the zone indicator
should carry a disconnection signal. To cut off the signal, set the Dip Switch on the Terminal to “ON”
position. After repairing the circuit lines, re-activate the Dip Switch on the Terminal and then
re-connect the external circuit line.
(3) Check for presence of any short circuit of the external wiring, or any defective detectors.
