Keypad Back Cover and Wall Tamper Installation
1. Rectangular Conduit (Trunking)
2. Knock outs for rectangular conduit using additional keypad base.
3. To use the keypad tamper spring (see Keypad Front and Back and
Terminal Block Wiring , item 4) as a wall tamper:
a. Break out this plastic cylinder inside the back cover.
b. Screw it to the wall, keeping it in the same hole as it was
attached, so the back cover fits over it. The plastic cylinder
prevents the tamper spring from being affected by flat objects
wedged in behind the keypad. The additional keypad base is
optional. For installations using it there is a similar, shorter,
washer style, plastic break out.
c. Place it behind the plastic cylinder and screw them down
together.
d. Then, place the holes in the base and keypad backing over top of
them.
e. Fit the spring inside the plastic cylinder part and secure the
keypad front to the keypad back. The spring compressing should
reset the keypad tamper condition.
