Fire-Lite MS-9200UDLSC Addressable Fire Alarm Control Panel - Manual (Page 28)

28 MS-9200UDLS Series Manual — P/N 52750:H 4/14/2014
Section 2: Installation
The cabinet may be either semi-flush or surface mounted. The cabinet mounts using two key slots
and two 0.250” (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 cabi-
net approximately 5 feet (1.5 m) 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 conductors into the box.
All wiring should be in accordance with the National and/or Local codes for fire alarm systems.
2.1 Mounting the Backbox
To prevent damage to the circuit board and to facilitate backbox mounting, the chassis with main
circuit board and transformer can be easily removed. Loosen the two 3/8” nuts securing the top
flanges of the chassis, then slide the chassis up to free it from the lower tabs. Place the chassis
assembly in a safe location until it can be reinstalled in the backbox.
1. Mark and predrill hole in the wall for the center top keyhole mounting bolt using the dimen-
sions illustrated in Figure 2.3 on page 30.
2. Install center top fastener in the wall with the screw head protruding.
3. Place backbox over the top screw, level and secure.
4. Mark and drill the left and right upper and lower mounting holes.
Note: Outer holes (closest to sidewall) are used for 16” O.C. stud mounting.
5. Install remaining fasteners and tighten.

CAUTION: STATIC SENSITIVE COMPONENTS
THE CIRCUIT BOARD CONTAINS STATIC-SENSITIVE COMPONENTS. ALWAYS GROUND
YOURSELF WITH A PROPER WRIST STRAP BEFORE HANDLING ANY BOARDS SO THAT
STATIC CHARGES ARE REMOVED FROM THE BODY. USE STATIC SUPPRESSIVE
PACKAGING TO PROTECT ELECTRONIC ASSEMBLIES.
