Important Notes:
1) The PSN-1000/E enclosure can house up to two (2) 18 AH batteries. Larger
batteries require accessory enclosure, part #SSU00500.
2) NFPA 72 requires 24 hours of standby power followed by 5 minutes alarm
activation.
3) NFPA 12, 12A requires 24 hours and five minutes of alarm activation.
4) Door holder circuits configured to disconnect upon AC loss need not be included
in the battery standby calculation since they will not draw power during that
time. Door holders will contribute to standby current draw when AC is present.
5) Total current must not exceed power supply rating (10A).
6) LED/Relay current must be accounted for in the battery calculation for the
supplying source.
