An exit bar has an elongated body for mounting on an exit door. The exit bar incorporates a pair of independent sensors. An infrared beam is generated along the front of the bar. An infrared detector produces a first signal when the beam is interrupted. The first signal results in release of a lock securing the door. If the beam is interrupted for longer than a pre-set time limit, a first alarm sounds. A capacitance sensor produces a second signal when the sensor detects changes of capacitance in the bar as a result of contact or near contact with foreign objects. The second signal also results in release of the lock securing the door. If the capacitance sensor detects a capacitance change for longer than a pre-set time limit, a second alarm sounds.
