Section 3: Mounting3.1 ADT-LCD40 Series Preparation
The ADT-LCD40 Series Annunciators can be surface mounted in a
three-gang electrical box such as the P/N SBB-3 (2.75" depth) or semi-
flush mounted in a three-gang elec trical box, P/N 10103 or equivalent,
with a minimum depth of 2 3/16". The ADT-LCD40 Series Annuncia-
tors cannot be mounted in three gangable electrical switch boxes con-
nected together. Select and remove the appropriate knockout(s), pull the
necessary wires through the knockouts and mount the three-gang box in
or on the wall depending on the type of installation desired. Be certain
that power is not applied to the wiring during the installation procedure.
Note: To ensure static protection, all enclosures, including the
ADT-LCD40 Series electrical box, must be connected to earth ground!
Never use the shield for grounding purposes.
To mount the ADT-LCD40 Series Annunciators in an electrical box, the
trim ring must first be removed. The trim ring is held in place by two
screws inserted through the top and bottom edge as illustrated in Figure
3-1. Removal of the trim ring will expose a metal flange with mounting
holes. Refer to “Hardware and Backboxes” on page18.
