Keypad Lightning/Surge Suppressor

This is a lightning and surge suppressor for keypad wiring at a gate or door. It goes between the keypad wiring and the gate operator or door control and needs an earth ground to work. It protects the operator or door circuitry from surges that come in on the keypad wires. It does not protect the keypad itself. A standard standalone keypad needs two: one on the power wires and one on the relay output wires. Features Protects gate operator or door circuitry For keypad power or relay wiring Requires earth ground Before You Order Order two for a standard standalone keypad: one for power, one for relay wires. Drive a ground rod or bond to a proper earth ground. Better grounding gives better protection. This does not protect the keypad. Protect the keypad itself separately if needed.
