do you have prints oer do you need them? /On the relay logic units, the electric strike was activated by both the door zone rely The electric strike was activated by the electric timer , the door zone relay (via the door zone limit) and the floor zone relay (Z1. Z2. Z3 ) (via the landing limit) These units were pretty bullet proff, so I'd measure for voltage at the stike , but i'd bet a bad strike.
