Approximately 3% of all returns (RMAs) are caused by
water damage. prox.pad plus units that are mounted
outdoors require certain preventive steps to avoid be-
ing damaged by water. This section discusses the rea-
sons water can accumulate in keypads and the steps

Use silicone to seal wire runs and mounting holes.
2.
Do NOT seal the cover and base together.
Keypads are designed to direct any water that
enters the two constituent pieces, base and cover,
towards the bottom and out a drain or weep hole.

drip loop. Often water follows the wires to the con-
nection point of the circuit board and shorts out the
terminals to which the wires are connected.
