[Fulltiming]

I will have to check to see where is trigger is but if I open the bay door that contains the alarm, and the alarm is armed, it does set the alarm off. So in addition to the panic switch in the bedroom and the entry door, opening the bay door that houses the alarm circuit will set the alarm off. That prevents someone opening that bay and disconnecting power to the alarm, thus disabling the alarm. I am not sure if it uses the same tilt switch that turns on the light in that bay or a separate switch. I will try to remember to check tomorrow for you. Your first photo is the tilt switch used to turn the light in that bay off and on. I will also look at my relays to see if mine are similar.
