Building codes essentially state that egress through access controlled doors must not require prior knowledge of operational requirements. Meeting this criteria, SDC'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.

Only 1/8" Total Bar Movement

The MSB550 has a maximum movement of only .125" (3.2 mm). Trigger activation to release the electromagnetic lock is quick and quiet

Heavy Duty Construction

The MSB550 utilizes heavy-duty aluminum extrusion and rugged end caps. The mounting assembly is all metal. The rigid construction prevents any malfunction due to sagging or warped doors or tweaked-glass door stiles

Narrow Low Profile

The MSB550 has a narrow profile with minimum projection from the door of only 1.875" (47 mm). The unobtrusive design is ideally suited for aesthetically superior glass openings.
