1.0 Overview Description The DS484Q and DS486Q are photoelectric quad beam detectors that use four pulsed infrared beams to activate an alarm relay upon detection of an intruder. Both models contain a transmitter that emits an invisible infrared beam, and a receiver. If the beam is broken, the receiver signals an alarm. Multiple channel operation provides increased system flexibility by allowing multiple devices to be used near each other without cross-talk or other interference.

1.3.5 Selectable Beams The beams in the DS484Q and DS486Q are configurable into eight different combinations (two groups by four channels). These combinations can eliminate false alarms that can occur from cross-talk when multiple beams are stacked, or when the transmitter and receiver are separated by a long distance.
