Hi Rocky,

Not totally crazy!!  Just last week I had to disassemble an exterior
gate controller that had spider webs and stink bugs on the circuit
board and was causing the "Fire Input" terminals to short and locked
the gate open.

As for this Ademco unit, that is something that is doubtful since
it is inside the house.  However, you are right it should be looked
at just to verify.

Thanks,

Les
