Notifier AFP-200

AFP-200 Instruction PN 15511:F2 10/11/99 75
Notes for Table A-3:
1) Refer to the Notifier Device Compatibility Document for compatible devices and their current draws.
2) For non-English language systems, the LCD-80TM (Terminal Mode) standby current is 0.100 A.
3) Do not enter current for NAC #3 and NAC #4 in Table A-3 if powering these circuits from an AVPS-24.
For more information on the AVPS-24, refer to Appendix J.
4) The RTM-8 alarm current is based on all eight alarm relays being activated. The alarm current can be
reduced by 0.019 A for each zone (between zone 1 and zone 8) that is not used by the system.
5) Enter the current from the Municipal Box data sheet into Calculation Column 2.
6) The Reverse Polarity Output values apply to the RTM-8, 4XTM, and Municipal Box.
Table A-4 Total Secondary Power Requirements at 24 VDC
A.5 Calculating the Battery Size
Use Table A-4 to calculate the total Standby and Alarm load in ampere hours (AH). This total load determines
the battery size (in AH), required to support the control panel under the loss of AC power. Complete Table A-4
as follows:
1) Enter the totals from Table A-3 Calculation Columns 2 and 3 where shown.
2) Enter the NFPA Standby and Alarm times (refer to “NFPA Battery Requirements” below.)
3) Calculate the ampere hours for Standby and Alarm; then, sum the Standby and Alarm ampere hours.
4) Multiply the sum by the derating factor of 1.2 to get the proper battery size (in AH).
5) Write the ampere-hour requirements on the Protected Premises label located inside the cabinet door.
NFPA Battery Requirements
• NFPA 72-1993 Local and NFPA 72-1993 Remote Station Fire Alarm Systems require 24 hours of standby
power followed by 5 minutes in alarm.
• NFPA 72-1993 Central Station, NFPA 72-1993 Auxiliary, and 72-1993 Remote Station require 60 hours of
standby power followed by 5 minutes in alarm. Batteries installed in a system powered by a generator need to
provide at least 4 hours of standby power.
• NFPA 12, 12A, 12B require 24 hours plus 5 minutes activation. The total ampere hours required cannot
exceed 17 AH with an internal charger.
