Why is Ampac NZ 100 heat detector not signaling fire?
If your Ampac Fire Alarms heat detector (opening contacts) is not signaling a fire, it could be due to too many smoke or electronic heat detectors on the detector line, or because a smoke-only link is fitted. Reduce the number of detectors on the line to the limits specified in Appendix A. Remove the smoke-only link (K1).
What to do if Ampac Fire Alarms system signals fire but zone is not in alarm?
If your Ampac Fire Alarms system signals a fire, the fire LED is on, but the zone is not in alarm, it could be due to the battery voltage being below 9.6V. If the mains are off, refer to the solutions for that problem. If the mains are on, disconnect the battery. If the voltage rises after disconnecting the battery, replace the batteries.
How to fix Ampac Fire Alarms zone always in defect when smoke only link is fitted?
If an Ampac Fire Alarms zone is always in defect and the smoke only link is fitted, it may be due to a shorted line, an open line, or a missing end-of-line resistor. Check the line for shorts and remove them. Inspect the line and correct any issues. Ensure a 6K8 resistor is fitted to the end of the line.
How to fix Ampac NZ 100 bell circuits in defect?
If the bell circuits in your Ampac Fire Alarms system are showing a defect, the possible causes are: * Diodes not fitted in series with the bell. * End-of-line resistor not fitted. * Fuse blown. To resolve this, fit diodes to the bells, ensure the end-of-line resistor is fitted as stated in table 4.2, and check fuse F2 on the PCB, replacing it if necessary.
What to do if Ampac NZ 100 zone is always in fire with smoke only link not fitted?
If an Ampac Fire Alarms zone is always in a fire state and the smoke only link is not fitted, it is likely due to an open circuit in the line or a missing end-of-line resistor. Ensure the line is correctly connected and fit a 6K8 end-of-line resistor.
Why is Ampac Fire Alarms manual call point not signaling fire?
If a manual call point in your Ampac Fire Alarms system is not signaling a fire, it may be because there are too many smoke or electronic heat detectors on the detector line, or a smoke-only link is fitted. Reduce the number of detectors on the line to the limits specified in table Appendix A. Remove the smoke-only link (K1).
How to fix Ampac NZ 100 Fire Alarms when mains LED is off?
If the Mains LED is off on your Ampac Fire Alarms system, it indicates that the mains supply is not operational or the AC Fuse on API 665 is blown. Check the mains supply. Also, check and replace F4 on API665 if necessary.
