SDC MSB550-2V-42 Request-to-Exit Switch Bar, Non-Latching, 2 SPDT Contacts, Aluminum, 42" Doors

The SDC MSDB550-2V-42 is a mechanical switch bar with two SPDT contacts. Building codes essentially state that egress through access controlled doors must not require prior knowledge of operational requirements. Meeting this criteria, the MSB550-2V-42 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 MSB5500-2V-42 is an economical alternative to sensor activated bars.

The MSB550-2V-42 has a maximum movement of only .125" (3.2 mm). Trigger activation to release the electromagnetic lock is quick and quiet. The unit 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.

The MSB550-2V-42 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. The unit features an aluminum finish and is designed for a 42" door.
