Stable and reliable pressure sense technology. Building codes essentially state that egress through access-controlled doors must not require prior knowledge of operational requirements. Meeting this criteria, 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 SDC SureExit® is the only tri-failsafe exit bar providing unequaled safety and reliability.

Unlike touch sensors, activation may be accomplished while wearing heavy gloves, by the hip through a coat, or using a briefcase. Superior egress safety is provided for frail, disabled or wheelchair confined persons unable to touch the bar and is easily activated by a cane or bump from a walker or wheelchair.

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.
