Grade A Mercantile Safe and Vault Listing

•
Follow the instructions given above for Mercantile Premises listing.
•
The back of the panel's box must have pry-off tamper supervision. Mount an ADEMCO
No. 112 Tamper Switch (not supplied with the VISTA-ULKT enclosure kit) into the hole
provided in the back of the panel box. This switch must be wired to zone 6. This switch
has contacts that are closed while the switch is depressed

Installing the Control's Circuit Board

Refer to Figure 4-3 when mounting the PC board.
•
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 the 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.
•
Swing the base of the board into the mounting clips and secure the board to the cabinet
with the accompanying screws.
Make certain that the mounting screws are tight. This ensures that there is a good ground
connection between the PC board and the cabinet. Also, dress field wiring away from the
microprocessor (center) section of the PC board. Use the two loops on the left and right-side walls
of the cabinet for anchoring field wiring using tie wraps. These steps are important to minimize the
risk of panel RF interference with television reception.
