APPENDIX A
POWER SUPPLY REQUIREMENTS
A-1
AC BRANCH CIRCUIT
The
PEGAsys
fire alarm/suppression control system requires connection to a separate dedicated AC branch circuit (120 or 240
VAC), which must be labeled FIRE ALARM. This branch circuit must connect to the line side of the main power feed of the protected
premises. No other equipment may be powered from the fire-alarm branch circuit. The branch circuit wire must run continuously,
without any disconnect devices, from the power source to the fire alarm/suppression control panel. When multiple power supplies are
installed in the system enclosure(s) they must all be fed from the same circuit. Over-current protection for this circuit must comply with
Article 760 of the National Electric Code, NFPA-72 as well as applicable local codes. Use a minimum of # 14 AWG with 600-volt
insulation for this branch circuit.
