• All wiring between the bell and panel must be run in conduit. Remaining wires do not need to be run in conduit.
• All wiring that is not run in conduit must exit from the knockout openings on the bottom or back of the cabinet.
• All unused knockouts must be plugged using the disc plugs and carriage bolts (supplied), as indicated in the
diagram below.
• Fasten the cabinet door to the cabinet backbox using the 18 one-inch-long Phillips-head screws (supplied) after all
wiring, programming, and checkout procedures have been completed.

Mercantile Safe and Vault Listing Guidelines
• Follow the guidelines given above for Mercantile Premises listing.
• Mount a shock sensor such as the System Sensor ASC-SS1 to the control's backbox. Follow the manufacturer's
instructions for proper sensor mounting. This sensor also must be wired to a hardwire zone.
•
For safe and vault applications, a UL Listed contact must be used inside the cabinet through one of the knockouts
for pry-off tamper purposes. This sensor also must be wired to a hardwire zone.
Installing the Control's Circuit Board
To install the circuit board in the cabinet, perform the following steps:
Step Action
1
Hang the three mounting clips on the raised cabinet tabs. Refer to Figure 3-3 (Detail B).
Make sure the clip orientation is exactly as shown in the diagram to avoid damage. This will also avoid
problems with insertion and removal of the PC board.
2
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 (Detail A).
3
Swing the base of the board into the mounting clips and secure the board to the cabinet with the
accompanying screws.
NOTES:
• Make certain that the mounting screws are tight. This ensures that there is a good ground connection between the
PC board and the cabinet.
• Dress field wiring away from the microprocessor (center) section of the PC board. Use the loops on the left and right
sidewalls of the cabinet for anchoring field wiring using tie wraps (Detail C). These steps are important to minimize
the risk of panel RF interference with television reception.
