Hello to All,
I am suddenly unable to disarm my Ademco 50P system. Any and all help appreciated.
Details:
- system was working fine for months.
- worker with key entered building unaware the alarm had been activated. When the alarm went off, he pushed the OFF (#1) button on the keypad. There are seven active model 6150 keypads installed.
- awakened by alarm, I entered my code then the OFF button on a different keypad. I do not know whether the worker and I were punching buttons at the same time.
- the alarm continued rather than going into DISARMED. After several attempts to disarm, I successfull experimented in changing the armed state from AWAY to STAY and back again. Again I do not know whether the worker was still pressing the OFF key.
- I answered Central Station's question that all humans were okay, I had them put my system into test.
- I then turned the system off for varying periods of time by throwing the ac current switch and pulling battery connections. I hoped this would somehow reset the system. That was yesterday.
- After leaving the system unpowered overnight, I just (09:30 EST) turned it on... then off. The system continues to stay armed.
Any thoughts?
TIA
Don Davis
