918W WIRING
See Fig. 3 for an example of a basic door installation.
The 918W is mounted adjacent to the door. An electric
door strike is mounted in the door jamb to release the
door lock. A magnetic switch is mounted on top of the
door jamb for detecting when the door is open. The
access host controller is located at a maximum distance
of 300ft of the keypad reader, depending on the reader
voltage provided.
Refer to the Fig. 4 or Fig. 5 for wiring details.
To avoid damage to the unit from static discharges,
mount the faceplate to a good earth grounding point.
Suggested wiring size is 18 AWG for earth ground.
