SDC’s patented SureExit® PSB560 series pressure sense bars are designed to release electromagnetic door locks for uninhibited egress. When slight pressure is applied to the non-latching bar, either of the two redundant solid state pressure sensors are actuated causing the electronics to immediately release the electromagnetic door locks.
 
A third redundant micro switch is automatically activated to release the door if both sensors or the electronics fail. This automatic emergency release switch does not require prior knowledge to find or use. Door operation will continue without the inconvenience of emergency service. 
 
The PSB560 series uses heavy duty aluminum extrusion and metal caps. The mounting assembly is all metal, and no plastic. The rigid construction prevents any malfunction due to sagging or warped doors or tweaked glass door stiles. With no moving parts the pressure sense technology does not suffer wear and provides quick and quiet operation.
