DS415i Photoelectric Intrusion Detector

The DS415i is a Photoelectric Intrusion Detector which consist of a 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 surface mount DS415i Photoelectric Detector provides AC/ DC operation and battery backup.

DS433i Single Beam Indoor Flush Mount Photoelectric Detector

The DS433i is a single-beam, indoor, flush mount photoelectric detector that is designed to mount in a standard single gang box. Its flush mount enclosure makes it an ideal choice where aesthetics are a concern. Internally pointable optics and the ability to mount in a standard single gang electrical box make it easy to install, especially for pre-wired applications.

DS453Q Quad Beam Indoor / Outdoor Photoelectric Detector

The DS453Q is a quad beam photoelectric detector that consists of separate transmitter and receiver. This detector operates both indoors and outdoors. The transmitter emits an invisible infrared beam to the receiver. If the beam is broken, the receiver signals an alarm. This detector uses four pulsed infrared beams that are designed to activate an alarm only when all four beams are simultaneously blocked. The DS453Q also features interlocked upper and lower beams, signal voltage LED, and selectable environmental discrimination circuitry.
