Why do all of my alarms chime and my security lights come on once a day at exactly the same time? It sounds like 5 high tone followed by 5 low tones. Not loud but very annoying. This happens when my alarm system is not activated.
What system do you have?
Do you have AHP and CM15A?
If you unplug the console prior to the expected alarm, do the chimes and lights still go off?
