Installing The Control; Mounting The Cabinet; Installing The Circuit Board; Installing The Lock - ADEMCO VISTA-120 Installation And Setup Manual

This section provides installation instructions for the following:

Mounting the Cabinet

• Mount the control cabinet to a sturdy wall using fasteners or anchors (not supplied) in a
clean, dry area which is not readily accessible to the general public. The back of the
control cabinet has 4 holes for this purpose.
• Before mounting the circuit board, remove the metal knockouts for the wiring entry that
you will be using. DO NOT ATTEMPT TO REMOVE THE KNOCKOUTS AFTER THE
CIRCUIT BOARD HAS BEEN INSTALLED.
Installing The Cabinet Lock
1. Remove the lock knockout on the
control cabinet cover. Insert the key
into the lock. Position the lock in the
hole making certain that the latch
will make contact with the latch
bracket when the door is closed.
2. While holding the lock steady, insert
the retainer clip into the retainer
slots.
Use an Ademco No. N6277 Cam Lock
and No. N6277-1 Push-On Retainer Clip
(supplied).
Installing the Control's Circuit Board
Refer to the Mounting the PC Board diagram.
• Hang the three mounting clips on the raised cabinet tabs. Make sure the clip orientation
is exactly as shown in the diagram to avoid damage to the clip when mounting screws are
tightened. This will also avoid problems with insertion and removal of the PC board.
• Insert the top of the circuit board into the slots at the top of the cabinet. Make certain that
the board rests in the slots as indicated in step 2 detail.
• Swing the base of the board into the mounting clips and secure the board to the cabinet
with the accompanying screws (as illustrated in the diagram).
