Battery Installation
WARNING
Improper battery connections or shorting battery terminals may damage the system
and/or batteries and may cause personal injuries.
Use the battery calculation chart to determine the battery size. Place the batteries in the space
provided in the bottom of the backbox. If a battery set larger than 12 AH (MPC-6000, RND-2)
or 18 AH (MPC-7000) is required, a separate enclosure must be used. The Faraday 14050
may be used for battery sets 18 AH and smaller. The Faraday BE-1 may be used for battery
sets 38 AH up to 100 AH.
The control unit uses a 24V battery set. Connect the two 12V batteries (or four 6V batteries) in
series with wire that is rated for the maximum worst-case battery current draw. Route the
battery leads to the left of the enclosure and up to the battery connector. The battery leads are
not power-limited. DO NOT CONNECT THE BATTERIES YET.
Powering the Control Unit
After all modules and wiring are installed and properly checked, apply AC power to the control
unit. AC POWER ON LED, SYSTEM TROUBLE LED, and the trouble buzzer should be on.
Observe polarity. Connect the B- (black) lead from the main board into the black or - terminal
of the battery set and the B+ (red) lead from the main board into the red or + terminal of the
battery set. (Refer to Primary and Secondary Wiring for diagram.)
Optional Modules
See Appendix D for the list of installation instructions for each optional module. Installation
Instructions are provided with each module. Follow these instructions for proper installation.
Check System Operation
Check for proper operation of all the system functions. See Operation Instructions section on
page 21.
WIRING
Basic system wiring and detector locations must be in accordance with NFPA 72 or other
instructions from the appropriate local authority having jurisdiction.
Devices that may be satisfactorily used with the control unit are shown in the compatible
device listing in Appendix B.
Wire reference data are included in Appendix A.
