Installation
2.1
Mounting Options
The cabinet may be either surface mounted or semi-flush
mounted using the optional Trim Ring P/N:
TR-1-R
. The
door is removable during the installation period by opening
and lifting the door off the hinges. The cabinet mounts using
two key slots and two additional 0.25" (6.35 mm) diameter
holes located in the backbox. The key slots are located at the
top of the backbox and the two securing holes at the bottom.
Carefully unpack the system and check for shipping damage.
Mount the cabinet in a clean, dry, vibration-free area where
extreme temperatures are not encountered. The area should
be readily accessible with sufficient room to easily install and
maintain the panel. Locate the top of the cabinet approxi-
mately five feet above the floor with the hinge mounting on
the left. Determine the number of conductors required for the
devices to be installed. Sufficient knockouts are provided for
wiring convenience. Select the appropriate knockout(s) and
pull the required conductors into the box. Note that there are
no knockouts on the left (hinged) side of the cabinet. All wir-
ing should be in accordance with the National and/or Local codes for fire alarm systems.
