Abstract
A multiple electromagnetic barrier lock system employs a plurality of electromagnetic lock assemblies for locking the barrier to the barrier frame. An armature assembly electromagnetically bonds to the electromagnet when the barrier is closed. Each armature/electromagnet assembly has an armature plate with an attractive face oriented toward the electromagnet and an oppositely positioned rear face oriented toward the barrier face. A mounting assembly is configured to mount the armature plate to the barrier face so that the armature plate is positionable in a first position closer to the barrier face and a second position away from the barrier face. A spring biases the armature plate to the first position.
