212R & 212SE Wiring Diagrams
TECHNICAL NOTES
●To avoid ESD (Electro-Static Discharge) interfering with the
operation of the keypad, ground the housing to earth ground.
●The bi-color LED provided with the SE keypad illuminates red when
the Lock-Release relay is de-energized and green when the relay is
de-energized.
●When mounting this unit outside, apply silicone to the area where
the wires enter the case. This helps prevent water from entering
the case and condensing on the circuit board. Do not silicone the
cover plate because the unit will not seal properly.
●Do not seal the drain holes at the bottom of the keypad housing.
This allows air to circulate and a place for condensation to drain.
●For use in extreme weather conditions, consult the factory for
additional methods of protecting your keypad.
●To speed installation of the SE keypad, holes have been spotted on
the inside the back housing for mounting to a wall or a single-gang
electrical box.
●On SE keypad, holes have also been spotted inside the front
housing for additional LEDs (LEDs not included).
