Used as an automatic Garage door closer with a "LiftMaster". Lower priced than commercial door closers such as the "SkyLink". This uses no external power and only uses door power when the door is not completely closed. Set to mode No. 36. It ever needs batteries. Simple on off switch acts as a bypass. The door sensing is a tab type microswitch that opens when the door is at the bottom. A bent metal tab attached to the top of the door actuates the microswitch.

It says 5v on the incoming product so I hope he can check 12v. when buying 5/12/24v I thought it was suitable for all.
