Bosch DS453Q Photoelectric Detector

The DS453Q from Bosch is a detector with separate transmitter and receiver. The transmitter emits an invisible infrared beam to the receiver. If the beam is broken, the receiver signals an alarm. The DS453Q use four pulsed infrared beams that are designed to activate an alarm only when all four beams are simultaneously blocked. The DS453Q also feature interlocked upper and lower beams, signal voltage LED, and selectable environmental discrimination circuitry.
