How a beam sensor works?

The primary objective behind using a beam sensor is to detect the differential movement and rotation in architectural constructions. There are mainly two types of beam sensors available in the market – horizontal for monitoring settlement or heave and vertical for monitoring lateral displacement and convergence. The beam sensor contains an infrared beam set that can be used for several applications, most commonly pedestrian doors. The beams fit comfortably into a pre-drilled ½” hole and are a snap fit. Wiring is by a quick disconnect cable that can be daisy-chained up to 30’ (in 15’ increments). The beams offer an LED indication at their back side for ease of alignment and troubleshooting.

Below is the installation description of a beam sensor. First you have to drill a ½” hole at the desired mounting location. When using more than one set of beams, alternate the beam orientation as shown at right. Route the cable from its end point to the desired beam mounting location. Then plug the beam cable in via the snap together connector. Install the beam into the ½” hole and press the beam until it clicks into the opening. Generally, the wall thickness of the drilled material should not go beyond 1/8”.

Now comes to wiring which is the most important part of bean sensor installation. If using a LO-Linx lockout module, plug each beam into the connection point at the module. Connection points are identified on the LO-Linx. If using Sensor Beams directly, be sure the NPN/Light Operate output works with the door controller.

The most common application where beam sensors are used is the home security system as a beam sensor emerged as an effective way shield their home and family from burglars and thieves that may cause harm to them. There are different types of beam sensors available in the market that aim to protect your homes but most of them cannot guarantee the effectiveness of the product. This is the reason why a comprehensive research in necessary before finalizing the beam sensor from a particular company. . The motion sensor is the latest one and it is also costly but it was said to be effective because of the active infrared it contain. It is not just being used by most home owners but also by various companies. A lot of people are hesitant to invest their money on such product because they are not conscious about the benefits it contains.
