6.4.2 Maximum Battery Standby Load
Tables 6.4 and 6.5 show the standby load calculations for the power supply based on 24 hours of standby. The standby load calculations
in the Table 6.3 must be less than the number shown in Tables 6.4 and 6.5 for the selected battery size, standby hour and alarm time. The
numbers below have a built in 20% derating factor for the battery ampere capacity.
Section 7: Testing and Maintenance
7.1 Periodic Testing and Service
Periodic testing and servicing of equipment is essential to ensure proper and reliable operation. Test and service the power supply
according to the schedules and procedures outlined in the following documents:
•
NFPA Standard 72’s section on Inspection, Testing and Maintenance
•
All test and maintenance instruction codes and software necessary to provide test and inspection requirements of CAN/ULC-S536,
Standard for the Inspection and Testing of Fire Alarm Systems
7.2 Battery Checks and Maintenance
Maintenance-free sealed lead-acid batteries used in the system do not require the addition of water or electrolyte. These batteries are
charged and maintained in a fully charged state by the main power supply’s charger during normal system operation. A discharged bat-
tery typically reaches the voltage of 27.6 VDC within 48 hours;. Sealed lead-acid batteries must be replaced within at most 5 years from
their date of manufacture. Minimal replacement battery capacity appears on the control panel marking label. Immediately replace a leak-
ing or damaged battery. Replacement batteries are available from the manufacturer.
