A two-point locking system for providing controlled access through a doorway is described comprising a controlled deadlatch assembly and a magnetic lock assembly. The controlled deadlatch assembly comprises (i) a deadlatch for selectively latching and unlatching a door, (ii) an input control device for selectively controlling the deadlatch, and (iii) a first wireless transmitter for transmitting a magnetic lock control signal. The magnetic lock assembly comprises (i) a metal housing unit, (ii) an armature plate, (iii) an electromagnetic element coupled to the housing unit and aligned to magnetically engage with the armature plate when selectively electrically energized, and (iv) a wireless receiver capable of receiving the magnetic lock control signal from the wireless transmitter. The magnetic lock control signal will typically disengage the magnetic lock assembly when the controlled deadlatch assembly is unlatched (thus unlocking the door and allowing access) and engage the magnetic lock assembly when the controlled deadlatch assembly is latched (thus locking the door and not allowing access). A second wireless transmitter can also be added to the magnetic lock assembly to communicate to a second wireless receiver at the controlled deadlatch assembly to provide two-way wireless communication between the two locking points.
