CAUTIONS
It is recommended that the printed circuit boards be removed for any
procedure that may cause dust, metal shavings, grease or any such
matter that may affect the circuit boards and/or parts. There may be
several sources of power into the control unit. Each source must be
disconnected prior to installing or removing modules, connecting or
disconnecting wiring, and programming jumpers.
CONTROL UNIT LOCATION
The control unit should be located near an exit at ground level where
the normal ambient temperature is maintained within the control unit
specification. The unit should be in an area that is free of dust,
vibration, moisture and condensation. Any auxiliary battery box or
other accessory not connected through a protective device or a circuit
designed for remote connection must be within the same room and
connected through electrical conduit.
INSTALLATION
The enclosures must be fastened securely to a clean, dry, shock-
free, and vibration-free surface. Consider the following when
mounting the box.
• Mounting height for visual and manual access to the Display
Board
• Weight and size of backbox
• Local mounting codes
When mounting the backbox, position the backbox clear of obstruc-
tions so that the door can open freely and so that indicators and
controls are easily accessible.
The fire alarm control unit must be mounted in a properly accessible
location as required by applicable codes. Any auxiliary battery box or
other accessory not connected through a protective device or a circuit
designed for remote connection must be within the same room and
connected through electrical conduit.
Installation is to be done only by qualified personnel who have
thoroughly read and understood these instructions. The fire alarm
control unit must be mounted in a properly accessible location as
required by applicable codes.
Install the backbox:
1. Select a clean, dry, shock and vibration free surface.
2. Position the backbox clear of obstructions so that the front door
opens freely and the controls and indicators are easily
accessible.
3. Mark the locations of the two upper mounting bolts of the
backbox on the wall.
Note: There are two key-shaped cutouts on the top of the
backbox. Make sure the end with the two key-shaped cutouts is
on top when installing the backbox.
4. Drill the two holes located in the previous step and screw in the
top bolts, leaving a small gap between the wall and each top bolt.
Note: The screw type and length must be able to support the
control unit, options and battery set. You may need a different
screw type, depending on the wall material.

5. Place the backbox over the two top bolts and allow it to slide
down over the bolts.
6. Mark, drill, and install the two bottom bolts in the backbox.
7. Tighten all four bolts securely against the back wall of the
backbox.
8. The BE-1 battery enclosure may be mounted immediately below
the main enclosure, close nipple, allowing a minimum of 1 inch
in between the enclosures for clearance between the doors.
Keeping the wire run to the control unit short will keep the
voltage drop to a minimum.
9. If a semi-flush mount installation is desired for the RND-2, use
the SFTK-6 Semi-flush Trim Kit. The backbox can be mounted
up to 3 1/2 inches into the wall. Place the semi-flush trim around
the backbox and affix to the wall with four #10 x 3/4 inch wood
screws (provided with trim).
Note: You may need a different screw type, depending on the
wall material.
Note: For semi-flush installations, if a BE-1 battery enclosure is
required, it may be mounted immediately above or below the
main enclosure, close nipple, allowing a minimum of 3 inches in
between the enclosures for clearance between the semi-flush
trims. Keeping the wire run to the control unit short will keep the
voltage drop to a minimum.
Remove Knock-Outs
1. Prepare the enclosure for electrical wiring, break out the
appropriate conduit entry points. Segregation is required between
power limited and non-power limited conductors. In order to
maintain the minimum separation, the following wire routing is
illustrated. Separation of at least a 1/4 inch is required between the
non-power limited and power limited conductors. Power limited and
non-power limited wiring must be run in separate conduit.
2. Attach conduit (if required) and run wires as required. Label
each field cable for future reference.
Basic system wiring and detector siting must be in accordance with
NFPA 72 or other instructions from the appropriate local authority.
Unit connections and limitations are as indicated on the wiring
diagrams included in System Wiring part of this manual.
Wire reference data are included in Appendix A of the MPC-6000/-
7000/RND-2 Owner’s Manual, P/N 315-447309.
Wiring Overview
In compliance with NEC Article 760 and UL 864, all power limited fire
protective signaling conductors must be separated a minimum of 1/4
inch from all of the following wiring located within a control panel:
• Electric light
• Power
• Class 1 or non-power limited fire protective signaling conductors
To meet these requirements, the following guidelines must be
observed when installing modules and wiring to this control panel.
When installing power limited field wiring, the installer must comply
with NEC article 760, which states:
The fire alarm power-limited circuits are installed using Types FPL,
FPLR, FPLP or permitted substitute cable, provided these power-
