Overview
What it is
ProBeam is a two-beam through-beam light barrier set from BBC Bircher Smart Access. The kit contains two transmitter sensors, two receiver sensors, a control box and the wiring needed to connect them. When either infrared beam is interrupted, the control box switches its relay contact.
What it is used for
The instruction manual describes ProBeam as a sensor that detects an intrusion so that an alarm, a door controller or a similar device can react. A typical use is a second safety beam pair across an automatic door or gate opening, wired to the door controller.
Key features
- Two independent beams (L1 and L2) evaluated by one control box
- Working distance from 15 cm up to 10 m between transmitter and receiver
- Relay contact output selectable as NO (normally open, default) or NC (normally closed)
- Sensitivity set with a distance adjustment potentiometer on the control box
- Power and operation LEDs plus an LED code for beam alignment
- Compact sensors that fit a 12 mm drilled hole, each with a 5 m cable
Buying considerations
ProBeam runs on 12 to 24 V AC or DC without polarity, so it can usually share the supply of a door or gate controller. The contact is rated 24 V at 1 A. The manual does not state an ingress protection (IP) rating, so confirm suitability before outdoor use.
Installation considerations
Mount each transmitter and receiver at the same height. The beam installation guide shows the lower beam pair at least 500 mm above the floor and the two pairs crossed (transmitter opposite receiver). Do not apply power while wiring.
Compatibility
The dry relay contact connects to any door controller, gate controller or alarm input that accepts a potential-free NO or NC contact.
