This is a pair of automatic door safety sensors, it should be connected to the door motor operator, once the infrared ray is blocked when the door closes, the gate will stop or reverse automatically to open.

It is compatible with different brands of garage and automatic gates, as long as it supports normal open contact / normal dry closure. Also works for security alarm system for access control. Please check the output terminal of the controller board and the wiring diagram before purchasing, please.

Note: It will not replace photocells such as Blue BUS or photocells whose receiving part only has 2 cable terminals. The receiver part of my photocell needs 4 cables.
