Abstract: An exit sensor bar for securing a door has an elongated housing and a mounting pad for mounting to a door. A circuit board assembly is disposed within the elongated housing in proximity to a blade of the mounting pad. The circuit board assembly includes at least an electro-optical source and an electro-optical detector coupled to a lock. The electro-optical detector selectively energizing and de-energizing the lock in response to the detection of light emitted from the electro-optical source. When a push force is applied to the elongated housing, the housing is displaced toward the mounting pad such that the blade obstructs light emitted from the electro-optical source. In response to the non-detection of the emitted light, the electro-optical detector de-energizes the lock freeing the door for egress.
