SDC MSB550-2Y Request-to-Exit Switch Bar, Non-Latching, 2 SPDT Contacts, Black Anodized, 36" Doors

The SDC MSDB550-2Y 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 MSB550-2Y 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 MSB5500-2Y is an economical alternative to sensor activated bars.

The MSB550-2Y 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 MSB550-2Y 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 a black anodized finish and is designed for a 36" door.
