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.

2. Wire Connection Box
In order to facilitate inspection, maintenance and repair, every floor or appropriate area shall install a
Wire Connection Box in which connecting joints are provided. The Box’s casing shall be water-proof
and the wording “Fire Fighting Only” should labeled on an aluminum plate.
3. Wire-Point Labels And Joint Clips
Inside the control panel and every Wire Connection Box, the wire points are to be attached to Label
Covers or Label Stickers and then connected to the Y-clip.
4. Wiring Method
Please refer to page 4 ~6
5. Terminal Resistor Connecting Method
Every end of Circuit line shall be fitted with a Resistor (not more then one). If any zone in the control
panel are not in use should set Dip Switch on the Terminal to the “ON” position, please refer to page 5
for details.
6. Zone Labeling
Once the wiring is completed, label the ‘Zone Labeling Card’ provided. For easy identification, type
or print the labeling cards.
7. Wiring Record
Once the external wires are laid a record of the detailed external wiring diagram shall be kept for
future inspection and repair.
zOPERATING INSTRUCTIONS
1. Fire Surveillance
After installing system devices to the panel, connect to an 220VAC 50/60HZ supply source, set all
switches on the display board to ready position. At this stage, the “AC Power” indicating LED will be
on, Voltmeter should indicate 24V (the allowable voltage is 20V-28V). Indicating Lamp in the
combination PBL box light up and surveillance begins.
2. Fire Alarm
When any detector has activated or manual call point has pressed, it is an indication of fire. At this
moment, the “Fire” Indicator (red) and the concerned zone indicator will light up simultaneously. The
Main Bell and Area Bell will also sound and the Indicating Lamp on the Combination PBL box will
switch from still to blinking. These activities indicate that the fire alarm is valid.
(1) Disable Main Bell
To stop the Main Bell from sounding, set the Main Bell Switch to ‘off’ position. The alarm will
stop immediately.
(2) Disable Area Bell
To stop the Area Bell, set the Area Bell Switch to ‘off’ position.
3. Reset
Once the fire alarm is activated, the “Fire” Indicator and the Related Zone Indicator will remain
lighted. If the control panel is required to start the surveillance again after the previous fire situation
has been resolve, just depress the ‘Revert’ button. However, if detectors have been burnt or the manual
call point press-down not recovered, reset cannot be activated. In this instance, repair should be
completed first, then depress the ‘Revert’ button to reset the system.

4. Disconnection Alarm
The panel is equipped with a ‘Zone Disconnection Auto Indication’ function. Should there be a
Circuit Break in certain areas, or detachment of the terminal resistor, the “Disconnection” LED and
the related zone indicator will blink simultaneously. The Disconnection Beeper will also sound. Upon
repair of the circuit, the above mentioned will cease.
(1) Stopping Disconnection Sound
To stop the disconnection sound, move the ‘Disconnection Sound’ switch to ‘OFF’ position.
5. Fire Alarm Test
To Perform Fire Alarm Simulation Test or test the functions of the fire alarm.
(1) “Auto Revert” switch “Accumulation” Switch. “Signal Transfer” Switch.
To perform one-men fire alarm test, first set “Auto Revert” switch to down position; set
“Accumulation” Switch to down “off” position; set “Signal Transfer” Switch to down “off”
position and then test the Circuit. For every Circuit tested, the signal will automatically reset itself.
(2) Field Fire Alarm Test
(A) Detector Test Method: use a Tester, place it near detector for a few seconds. As soon as
detector has back to normal condition, the fire alarm signal on the control panel will
automatically reset itself.
(B) Manual Call Point Test Method: depress the manual call point to activate the alarm. Pull up
the button and the fire alarm signal on the control panel will automatically reset itself.
(3) Control Panel Self Testing
After repeat test (1), set “Test” Switch to ‘Test’ position, “Fire Test” Switch to ‘Test’ position, and
then depress Zone Test button (on the Zone Indicator). It will automatically reset after the test.
Once completed, set all switches to up position.
6. Disconnection Test
(1) Set “Test” Switch to ‘Test’ position, set “Disconnection Test” Switch to ‘Test’ position, and then
depress Zone Test button (on the Zone Indicator). It will automatically reset after the test. Once
completed, set all switches to ‘up’ position.
(2) Disconnection Site Test: remove the Detector.
7. Standby Power
The panel is equipped with automatic rechargeable batteries the stand-by power source (24VDC) shall
be installed during operation. When the Main power source has been terminated, the “AC Power”
Indicating LED will light off and the “Battery” Indicating LED will light up. The Voltmeter reading
will indicate 24V.
(1) Stand-by Power Test
The control panel should be powered by the main source under normal condition. To test the
function of the stand-by power source, depress “Battery Test” Switch and the control panel should
response same as power-off situation.
