WebMar 7, 2024 · A motion sensor (or motion detector) is the linchpin of your security system because it detects when someone is in your home when they shouldn’t be. A motion sensor uses one or multiple technologies to detect movement in an area. When a sensor detects motion, it sends a signal to your security system’s control panel, which connects to your …
WebSystem Sensor BEAM1224S consists of a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector, the smoke causes a reduction in the signal. When the smoke level reaches the predetermined threshold, an alarm is activate.
