Wired

It connects to the installation system with a cable and is powered through it.

The number of beams indicates the quantity of infrared rays connecting the transmitter to the receiver. More beams mean greater coverage height and fewer false alarms, as all beams must be interrupted simultaneously to trigger the system.

The range indicates the maximum distance (in meters) that the transmitter can be from the receiver in order to operate reliably.

It refers to wired beam detectors and indicates how much voltage (in Volts) the detector needs to operate.
