Section 2. INSTALLING THE CONTROL

This section provides instructions for mounting the control cabinet, and
installing the cabinet lock (if used). Also included in this section are instructions
for the following:
• Installing the main PC board.
• If used, optional mounting one of the following in the cabinet with the main
PC board: RF Receiver board, 4204 Relay unit, 4219 Wired Expansion
unit, or 4229 Wired Expansion/Relay unit.
• Standard phone line connections.
• Installing the back-up battery in the cabinet.
• Connecting the AC transformer.
• Making earth ground connections.

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. Four mounting holes are provided at the back of the cabinet.
If an RF Receiver is being used and you intend to mount its PC board within
the cabinet, note the following:
• Do not mount the cabinet on or near metal objects. This will decrease RF
range and/or block RF transmissions from wireless transmitters.
• Do not locate the cabinet in an area of high RF interference (revealed by
frequent or prolonged lighting of the LED in the receiver after it is
operational). Random flicker is OK.

Installing the Lock (if used)

Use an Ademco No. N6277 Cam Lock and No. N6277–1 Push-On Clip
(Retainer Clip).
