FREQUENTLY ASKED QUESTIONS

Q: Panel does not power up when connected to mains

Solution:

1. Check that there is a fuse in the mains fuse holder on the transformer
2. Check that the mains fuse has not blown
3. Check the large fuses on all boards in the panel
4. Check that all power cables are connected, and not loose
5. Check that the mains is actually being supplied

Q: Panel does not power up on batteries

Solution:

1. Check that both batteries are connected correctly
2. Check that the polarity of the batteries is correct
3. On larger panels, check the power supply has not cut out by pressing the button on the power supply board (under main board)
4. Check the large fuses on all boards in the panel

Q: When turned on the panel does nothing, except the buzzer, which constantly sounds

Solution:

1. Check there is a processor in the main socket on the board
2. Check that this chip is correctly inserted into the socket

Q: The buttons on the panel do not work

Reason: Keypad not enabled
Solution: To enable the keypad you need to use the enable key switch.

Q: A zone indicator is showing, with no corresponding system fault

Reason: That zone is currently isolated
Solution: Follow isolation instructions to take zone out of isolation

Q: A Zone fault indicator is pulsing, together with the Zone Indicator

Reason: There is a problem with the zone (open circuit)
Solution:

1. Check that there is an end of line resistor installed on the zone
2. Check that the end of line resistor is a 4k3 Resistor
3. Measure the zone voltage (a 23V zone indicates open circuit, 20V is normal, 12V in fire)

Q: A Zone indicator is showing (constant), together with the Zone Indicator

Reason: There is a problem with the zone (short circuit)
Solution:

1. Check to see if there is a short on the zone
2. Measure the zone voltage (a 0V zone indicates a short, 20V is normal, 12V in fire)

Q: Everything is fine until a call point is operated, then the panel shows a short circuit on that zone

Reason: There is no inline resistor with the call point


Q: A Zone indicator is showing, together with the Detector Indicator

Reason: There is a problem with one of the detectors on the zone
Solution:

•  Check to see if all detectors on that zone are correctly installed.

•  If the problem continues take the following steps. Bring the end of line resistor back to the panel, if there is a problem here then you have a faulty panel, if there is no problem then continue to move the eol resistor along the zone, to each detector on that zone, one at a time. As soon as the panel starts to indicate a fault you know the detector you have connected the eol to has a fault.

Alternatively you can measure zone voltages. There will be a 0.2V drop in voltage (from the zone voltage at the panel) on the line before the faulty detector.

Q: A Zone fault indicator is pulsing, together with the Sounder Indicator

Reason: There is a problem with the sounder circuit (open circuit)
Solution:

1. Check to see if all sounders on that circuit are correctly installed
2. Check that there is an end of line resistor installed on the circuit
3. Check that the end of line resistor is a 4k3 Resistor
4. Measure the line voltage (normally 15V, 20V when open circuit)

Q: A Zone indicator is showing (constant), together with the Sounder Indicator

Reason: There is a short on the sounder line
Solution:

•  Check to see if all sounders on that circuit are correctly installed, a sounder connected in reverse will give a short circuit fault
•  Check to see if there is a short on the zone
•  Measure the line voltage (0V indicated a short)

Q: The power indicator is flashing

Reason: There might be a problem with the mains supply
Solution:

•  Check that the mains fuse has not blown

•  Check the large fuses on all boards in the panel

•  Check that all power cables are connected, and not loose

•  Check that the mains is actually being supplied

•  Disconnect the batteries, is the panel still working? If it is, then the psu-main board wiring may be incorrect, this can happen when the main board is disconnected. Check that the sequence of cables coming from the psu is the same sequence as goes into the bottom of the main board.

Q: The power indicator is on constantly

Reason: There is a problem with the batteries
Solution:

1. Check that both batteries are connected correctly
2. Check that the polarity of the batteries is correct
3. Check the large fuses on all boards in the panel
