International Door Closers MSB550 Mechanical Switch Bar
Non-Latching Push Bar for:
Building codes essentially state that egress through access controlled doors must not require prior knowledge of operational requirements. Meeting this criteria, IDC's MSB550 is designed to release electromagnetic door locks for uninhibited egress. When slight pressure is applied a microswitch is actuated, immediately releasing the electromagnetic door lock.
The MSB5500 is an economical alternative to sensor activated bars.
