The relay-based system connects two door-position contacts to a local control assembly and coordinates the corresponding locks. Request contacts initiate access, while relay changeover contacts provide the switching paths for locking and indication. The package is intended for a simple vestibule with two entrances. Its hardwired arrangement keeps the operating sequence local and allows the control enclosure and peripheral devices to be positioned around the actual door layout.
