ABSTRACT:
The present invention is directed towards a security system for a multi-unit facility such as a hotel wherein access to each unit or room is accomplished through a door structure or like closure which incorporates a separate locking assembly. The locking facility is of the keyless entry type wherein a preset code is fed into an electronically controlled lock through a plurality of finger operated switches (fingerboard) for authorized entry. Each of the actuating facilities associated with each closure is capable of having a stored preset code changed through operation of a microprocessor. Telephone lines interconnect the activating and locking facilities associated with each room to a central control facility, for example, in the office of a hotel.
