The ‘Faulty display Led’ is illuminated on my Yale HSA6400 Alarm system and it beeps every 30 seconds. I assumed that there must be a low battery condition in one of the 5 PIRs or 2 door sensors. The only other devices on the system were two keyfobs but have removed them from the system. However none of the PIRs flash when walking across the front of them. Neither of the Door alarms flash on opening the door.
The instruction book states that setting the Alarm or Home alarm will display the device at fault but I tried setting both of them and there was no fault display.
I have checked that the power supply is OK (14v). None of the devices have been tampered with.
How do I determine what the fault is?
Thanks, Peter Scott
