Maximum Battery Standby Load; 2: Current Draw Worksheet For Idp Slc Devices - Honeywell Farenhyt RPS-1000HV Manual

Calculating Current Draw and Standby Battery

Maximum Battery Standby Load

Table 2.3 shows the maximum battery standby load for the RPS-1000 based on 24 and 60 hours of standby. The numbers below have a built
in 20% derating factor for the battery amp-hour capacity. The standby load calculations of line G in the Current Draw Calculation Worksheet
must be less than the number shown in Table 2.3 for the battery size used and standby hours required.
1 Required for NFPA 72 Auxiliary Protected Fire Alarm systems for Fire Alarm Service (City Box) and Remote
Station Protected Fire Alarm systems (Polarity Reversal) and Digital Alarm Communicator/Transmitter (DACT)
NOTE: The maximum battery size for FM (Factory Mutual) installations is 33AH.
2.5.2 Current Draw Worksheet for IDP SLC Devices
For each RPS-1000 in the installation, use this worksheet to determine current requirements during alarm and battery standby operation. See
individual FACP manual for maximum number of devices.
For each device use this formula:
