Grade A Mercantile Safe and Vault Listing
For a Grade A Mercantile Safe and Vault listing, perform the following steps:
Step
Action
1
Follow the instructions given above for Mercantile Premises listing.
2
Mount a shock sensor such as Sentrol No. 5402 to the control's backbox. Follow
the manufacturer's instructions for proper sensor mounting. This sensor also
must be wired to a hardwire zone.
3
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 control’s circuit board, perform the following steps:
Step
Action
1
Hang the three mounting clips on the raised cabinet tabs. Make sure the clip
orientation is exactly as shown in figure 4-3 to avoid damage to the clip when
mounting screws are tightened. 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.
3
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 2 loops on the left and right sidewalls
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.
