How to connect photobeam detector to alarm system ?
Photo Beam Detectors also called Infrared (IR) beam detectors that are widely used in perimeter intrusion detection. Photo beam detector consist of transmitter and receiver. The transmitter emit the infrared beam, you only need to connect it with the power supply (DC voltage among 12V - 18V). The receiver part is receiving the infrared beam from transmitter with the signal processing components inside. The receiver with inputs of power supply and relay outputs, you need to connect power supply also, the relay output need to connect with wired zones of alarm system. Please note that every hardwired alarm systems with EOL resistor design to provide protection of cable cut and cable short circuit. You need to connect the EOL resistor between the hardwired zones and IR beam detector.
If you are using our all-in-one alarm kits with hardwired zones, before use the hardwired zones, you need to set the zones are not belong to Bypass Zone.
If you purchased the Wireless Infrared Beam Detector from us, then you only need to connect the power supply for them, not need to connect any other wires. Simply trigger the beam detector, the beam detector will send wireless signal out to wireless alarm control panel.
1, 2 are power inputs for photobeam detector, 3,4 are Relay outputs (Normally Closed). Red is +, Black is -, Blue and Yellow are for wired zone.
Notice for connection:
- Photobeam detector work under DC voltage of 12V-18V, do not connect to AC voltage. Transmitter and receiver can share the same power supply.
- In this diagram, we are showing Normally Closed (N.C.) connection method.
- In this diagram, we don't use the tamper protection features.
- If you don't use the zones, then you need to put the EOL resistor on the wired zones.
- When testing photobeam, you need to put transmitter and receiver in the detection range, then trigger the photobeam.
