confirmation.

Q26. Isolator module does not work?
A: Isolator connects to panel via IN terminal and connects to loop device via OUT terminal. When isolator detects short circuit or overload on OUT terminal, it will cut-off the IN terminal. First assume that isolator module is normal, connect  loop device one by one to check if any of them is faulty to cause the isolator cut-off. When isolator is cut-off, the S+/S- will also shut-off and all connected devices will become faulty.

AH-03312 Trouble Shooting 

(1) Examine Indicators: This system is composed of several devices and it will be affected by defective and improper use of detectors, wirng, bells, and manual call points.
a. Use a multi-meter to test the voltage at the AC input contacts.
b. Check that the Power Normal indicator shines.
c. See whether any fuses are burned out.
d. Check that the extemal devices and wiring are nomal.

(2) Fuse Function: The fuses in the panel have a special protective function, so do not use unspecified or poor quality products. Faulty external wiring and poor quality products will make fuses burn out.
a. AC: Normal power 220V AC fuse (2A).
b. BATT: Backup battery fuse (2A).
c. SND1 and SND2: Bell fuse (Auto-reset).
d. AUX: Output fuse (Auto-reset).
e. 24 V DC: DC power output fuse (Auto-reset).

(3) Reasons for Burned Out Fuses and Inspection Notes:
a. AC power fuse burn out: Check whether the applied power is over the specified value and if the specification is correct. (Using a fuse lower than specified will make the fuse burn out)
b. Backup battery fuse burn out: Check whether the polarity of the contacts is right.

(4) False Bell Alarm: The improper wiring can make the bell sound when no alarm signal is given. Please remove the extemal wiring and then use a multi-meter to test the bell's contacts which shouldn't give 24V DC reading. If it meets the mentioned requirement, please check the extemal wiring.

(5) Zone Abnormal Status ( Zone FaultDisable Indicator ON ): According to the statistic, most zone faults are due to incorrect wiring. Some other reasons for fault are improper use and misconnection to contacts.
Inspection Notes are as below:
a. Check the unused zones to see if the end of line resistors have fallen off.
b. Disconnect the zone wiring and connect a 4.7K ohms resistor across the contacts.
The fault signal should disappear.
c. If above conditions are met, the control panel is in normal condition. The fault signal is being caused by an external wiring fault. After repairing the external wiring, you may connect the wiring to the control panel again.
d. Check whether the extemal wiring is short circuited or disconnected, detectors have fallen off or loosened or are detective, and the end of line resistor in detectors have fallen off or was not installed.
e. Use a multi-meter to check that the resistance across the L(Z+) and LC(Z-) contacts is about 4.7K ohms.
f. Disconnect the wires leading to the contacts L and LC. Check the voltage across the two wire is 0 volts. 

(6) Zone Alarm and Alarm Indicators ON : Inspection notes:
a. Disconnect the faulty zone and check the resistance across the L and LC wires is about 4.7K ohms.
b. Disconnect the faulty zone, the Zone Alarm indicator will go out and the Zone Fault/Disable indicator will light up. If you would like to make the Zone Faulty indicator go off, you should install the end of line resistor across the L(Z+) and LC(Z-) contacts of the Zone. After repairing the wiring, please reconnect the extemal wiring.
 
 

PERMANENT MAINS / BATTERY FAULT

1. Check the MAINS ON light is lit. If not, check the mains supply and fuse (adjacent the transformer).
2. Check the battery supply (RED lead to BT+ terminal, BLACK lead to BT- terminal). If the battery leads have been connected the wrong way round the battery fuse (F3) will blow, however a permanent power fault may have been caused and CANNOT be reset.
3. Check 24 Volt batteries of the relevant size are connected in series.
4. Check the wiring is connected properly to 11112-1-J4.
5. Check the transformer leads are pushed on to the tags on the transformer properly.
6. if the MAINS ON & FAULT /AC/DC lights are still lit, the batteries are either over
discharged or have failed - try a new pair, even new batteries can fail.

If the batteries are completely discharged or if they are inferior but still working, the battery fault circuit will still show a fault - check this using new batteries. Please note that a fully charged 24 Volt battery will measure 25 to 28 Volts.

A battery measuring less than 21 Volts that has been charged from the panel for more than 10 minutes is unlikely to recharge properly and should be replaced. The battery monitoring circuit will show a FAULT /AC/DC, which, if it does not cease, means that the batteries are faulty.

If good but completely discharged cells are used the FAULT /AC/DC light may stay on for several minutes until the battery obtains sufficient charge.

MANUAL CALL POINTS, HEAT DETECTORS, OR SMOKE DETECTORS TRIGGER, BUT DON'T CAUSE A FIRE CONDITION. Either the wrong value call point resistor has been fitted in series at the call point or detector or a resistor is already fitted inside . If you have fitted a resistor try shorting it out and re-testing the device. Check the panel is OK, by removing the detector wiring and then re-inserting the End of Line Resistor into the terminals to give a normal condition.Then simulate a fire condition on the zone with a 470 to 680 Ohm resistor. If the zone goes into fire the device under test may be out of specification.

RESET BUTTON DOESN'T RESET THE PANEL FROM FIRE CONDITION Press SILENCE first.

RESET BUTTON STILL DOESN'T RESET THE PANEL (PERMANENT FIRE CONDITION) 
Either a call point is triggered in which case replace the glass or if an older bi-metal heat detector has triggered, wait for it to cool down and reset itself. Alternatively a smoke detector may be faulty and will not unlatch, in which case the LED on the detector may not be lit, or a call point may have failed in the triggered state. If you suspect a faulty device then you can only find it by following logical tests. Start by removing the wiring at the panel and refitting the End of Line Device (EOLD) to prove the panel is OK. Reconnect the wiring and replace the EOLD on the last device. Then starting at the end of the line, remove each detector in turn, then press Silence then Reset. When you reach the faulty device the panel will remain reset.

PERMANENT ZONE FAULT
Disconnect the zone completely and refit the End of Line Device (EOLD) at the panel. If the fault condition clears then there is a wiring fault. Double check and refit the wiring and EOLD on the zone and trace the fault with consideration for the type of fault indicated by the internal Fault leds (11112-1-D32,11112-1-D33).
A common fault is a detector badly seated in a base, which has not properly made connection. This will show as an open circuit Fault.

PERMANENT SOUNDER FAULT
Check the Sounder fuses (11112-1-F2) on the pcb have not blown and replace if necessary. If either fuse is blown a sounder fault will show. Check the correct End of Line Resistors have been fitted. Disconnect the relevant zone from the terminal block refit the end of line resistor only. If the fault condition clears there is a wiring fault.
Note that the sounders must be polarised.

BUTTONS DON'T WORK
Turn the keyswitch to ON controls and press SILENCE and then RESET. If the fault persists, check the connection from the keyswitch is seated correctly on pcb plug (11112-1-J3).

PERMANENT MAINS / BATTERY FAULT

1. Check the Power Fault light. If the LED steady ON, check the mains supply AC power switch (11212- 1-SW1/11412-1-SW1) and fuse (1112-2-F1 : adjacent the ON-OFF Switch).
2. Check the Power Fault light is lit. If the light is flash, check the battery power switch (11212-1-SW10/1 1412-1-SW10) and battery supply (RED lead to BT +terminal, BLACK lead to BT - terminal). If the battery leads have been connected the wrong way round the battery fuse (11212 -1- F3/11412- 1-F5) will blow, however a permanent power fault may have been caused and CAN NOT be reset.
3. Check 24 Volt batteries of the relevant size are connected in series.
4. Check the wiring is connected properly to 11212-1-JP18/11412-1-T6.
5. Check the transformer leads are pushed on to the tags on the transformer properly. 
6. if the Fault & Power FAULT lights are still lit and flash, the batteries are either over discharged or have failed - try a new pair, even new batteries can fail.

If the batteries are completely discharged or if they are inferior but will still working, the battery fault circuit will still show a fault - check this using new batteries. Please note that a fully charged 24 Volt battery will measure 25 to 28 Volts.

A battery measuring less than 21 Volts that has been charged from the panel for more than 10 minutes is unlikely to recharge properly and should be replaced. The battery monitoring circuit will show a Power Fault, which, if it does not cease, means that the batteries are faulty.

If good but completely discharged cells are used, the Power Fault light will still flash for several minutes until the battery obtains sufficient charge. 

MANUAL CALL POINTS, DETECTORS TRIGGER, BUT DON'T CAUSE A FIRE CONDITION.
Either the wrong value call point resistor has been fitted in series at the call point or detector or a resistor is already fitted inside. If you have fitted a resistor try shorting it out and re-testing the device. Check the panel is OK, by removing the detector wiring and then re-inserting the End of Line Resistor into the terminals to give a normal condition. Then simulate a fire condition on the zone with a 470 to 680 Ohm resistor. If the zone goes into fire the device under test may be out of specification.

RESET BUTTON STILL DOESN'T RESET THE PANEL (PERMANENT FIRE CONDITION)
Either a call point is triggered in which case replace the glass or if an older bi-metal heat detector has triggered, wait for it to cool down and reset itself. Alternatively a smoke detector may be faulty and will not unlatch, in which case the LED on the detector may not be lit, or a call point may have failed in the triggered state.

When you reach the faulty device the panel will remain reset.
 

PERMANENT ZONE FAULT
Disconnect the zone completely and refit the End of Line Device (EOLD) at the panel. A common fault is a detector has not properly connected with base. 

GROUND FAULT
Check the PCB 11412-D18 light. If the LED steady ON, Check the input and the output contact line occurs with the cabinet or the earth has the short cut condition.

PERMANENT SOUNDER FAULT
Check the Sounder Fault light is lit. If the LED steady ON, check the correct End of Line Resistors have been fitted. Disconnect the relevant zone from the terminal block and refit the end of line resistor only. If the fault condition clears there is a wiring fault.
Note that the sounders must be polarised.

BUTTONS DON'T WORK
Turn the keyswitch to ON controls and press any switch. If the fault persists, check the connection from the keyswitch is seated correctly on pcb plug 11212-SW12/11412-SW25.
