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 tem-
peratures 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 approximately 5 feet (1.5 m) above the floor with the hinge mounting on the left. Determine the number of conduc-
tors 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
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.
To prevent damage to the circuit board and to facilitate backbox mounting, the chassis with main circuit board 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 pre-drill hole in the wall for the center top keyhole mounting bolt using the dimensions illustrated in Figure 2.2 on
page 23.
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.
6.
When the location is dry and free of construction dust, install the chassis/circuit board assembly.
7.
Mount the chassis to the backbox by aligning the two mounting tabs with the slots in the backbox, then position the two mounting
hole tabs over the studs with nuts located in the upper portion of the backbox.
8.
Slide the tabs located on the bottom of the chassis into the mounting slots in the backbox by pressing the chassis down.
9.
Secure the chassis to the backbox by tightening the two mounting nuts (#10-32) at the top, and to ensure proper grounding, use a
3/8" nut driver or socket.
10. If the main circuit board is not already attached to the chassis, install it by positioning the ten mounting holes over the studs on the
chassis and secure with the supplied screws.
