Section 4 - Installing The Control

4-3

Grade A Mercantile Safe and Vault Listing

• Follow the instructions given above for Mercantile Premises listing.

• 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.

• 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

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 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 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.
