AH-02412 FAMILY

Due to the creativity and progress of fire fighting technology among

highly developed countries, we never give up any chance to upgrade

our new generation fire alarm control panel. We are not only pursuing

higher technology level, but also compact design to meet national

quality standard.

..

This digital control panel primary uses processor to handle relevant

signal, which improve most weak points of traditional control panel.

See below for more details.

(1)The use of microprocessor has improved the unit's correctness

that used to be affected by bad characteristic of traditional devices.

(2)Uses digital mode to transmit and control signal process, which

highly increase the precision of signal.

(3)Internal control voltage uses 5V that prevent burning circuit caused

by traditional high voltage.

(4)Module type design simplified entire system, function up-grade just

has to change related module and no need big work to complete it.

Thus, users are able to save big bucks on up-grade or repair cost.

(5)Microprocessor can be revised according to user's request, its

expand ability has much greater than traditional ones.

(6)Shortage of terminal has not seen on this unit, up to four sets of

signal transfer contacts (relay outputs) are added for new design.

(7)Zone isolating button and control board switches are electronic-type

and used digital 0 and 1 signals for switch control signal. Also they

will not damaged by abnormal high voltage because of undirected

control high voltage and interfered by dust, this phenomenon

usually happened on mechanical-type switch.

Trouble 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 & Combination PBL Box

The system devices are assembled with many single units (refer

page 2), either the 'Detectors', 'Circuits' or 'Combination PBL Box '

become defective, it will affect the functionality of the Control Panel.

(1)Measure terminal "AC" with a Multi-meter for any voltage.

(2)Check whether the "System Normal" indicator is functioning

properly. The system should specify 24V DC.

(3)Check whether fuses are in good condition.

(4)Check whether the external devices and wiring conform to

specifications, as stated in this handbook.

2.Function of Fuses

The Control Panel has fuses, each fuse with individual protection

function. It must not be replaced with fuses that do not conform to

specifications or are of bad 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.

(1)AC: Fuse for power source AC.

(2)BATT: Fuse for standby power source.

(3)SND1,SND2: Fuse for alarm bell. (Resettable type)

(4)AUX: Fuse for Combination PBL Fire Indicating Lamp.

(Resettable type)

(5)DC24V: Fuse for direct current source 24VDC. (Resettable type)

3.Causes of Burnt Fuses & Inspection Guidelines

(1)AC Fuse Burnt

a.It could be due to excessive voltage supply that causes the AC

Fuse to be burnt.

b.Conformance of Specification (lower-rated fuse may be burnt

by a surge of current).

(2)BATT Fuse Burnt

a.Check whether the standby power polarity '+' and '-' have been

in reversed position.

b.Similar to inspection guidelines for AC Fuse, the standby power

supply will pass through BATT Fuse when power supply from

the Main Source has been cut-off.

4.Combination PBL Fire Indicating Lamp & Alarm Bell Malfunction

(1)Remove the external wiring of the Fire Indicating Lamp and

Alarm Bell.

(2)Measure the ( '+' and '-' ) outlet of Fire Indicating Lamp with a

multi-meter and Check whether it is read DC24V. Then perform

a fire test. Reset after it is completed.

(3)Measure the ( '+' and '-' ) outlet of the Alarm Bell with multi-meter.

It should not have any voltage supplied. Then perform a fire test

and a DC24V voltage should be recorded. Reset after the test.

(4)When the test results conform to (2) and (3), it indicates that the

control panel is functioning properly. The wires should only be

connected after the external wiring have been repaired.

5.Zone "Fault" Indicator & "Fault/Disable" Indicator light up

When one or several "Fault/Disable" Indicator and "Fault" Indicator

light up 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 loops in the control panel not use End-of-line

resistor.

(2)Remove the circuit that in trouble; 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 mode and measure the malfunction

circuit resistance value. The resistance value between the zone

line and common line should 4.7k .

(7)After removal of the circuit line, there should not be any voltage

between the zone line and zone common line. The wire shall only

be connected after the external wiring has been repaired.
