Need your advice. I got the situation accurately constrained (i.e., not a wide open SNAFU...)
Problem Statement ================= On Zone 1 only... Keypad indicates OPEN even though all doors and windows are closed. Doors (say A and B) fail to chime when repeatedly opened/closed. Other doors and windows chime, but pad stills says OPEN. Usually problem exists for a couple days then heals itself. Then problem returns.
Generally speaking, this problem is relatively recent with years of reliable prior service.
Experimental Results ==================== I took a strong magnet and tried to trigger sensors A and B.
Opened door A (no chime), put magnet on sensor, but no chime. Closed door A. (...obviously, no chime, pad still says open)
Open door B (no chime), put magnet on sensor, CHIME!! Remove magnet, CHIME! Close and open door A. CHIME! CHIME! Close and open door B. CHIME! CHIME! Keypad accurately depicts open/close.
....then (within minutes/hours) keypad stuck on open again.
Magnet trick fixes the problem again (temporarily).
Possible Root Causes ==================== Door B (the front door) does not close tightly. It moves easily 3/8 inch in-out when "closed". Damn kids slam door, so it likely vibrates 5 times before settling. Door jam sensor and door magnet poorly aligned. They overlap less than 50% when closed. Vibration would cause the overlap to decrease.
Per past thread, a vibrating door might confuse the controller.
Possible Correct Actions ======================== A] Lock the kids outside. B] Replace the sensor. C] Move the door magnet to increase overlap with sensor. D] Replace old weather stipping to try to reduce door vibration.
Or, some other advice...
Thanks in advance!!
