Calculating Current Draw and Standby Battery

This section is for helping you determine the current draw and standby battery needs for your installation.
3.7.1

Current Draw Worksheet Requirements

The following steps must be taken when determining IFP-2100/ECS current draw and standby battery
requirements.
1. You will use the Current Draw Worksheet to determine current draw and standby battery requirements. Use
Table 3-2 if installing IDP SLC Devices, Table 3-3 if installing SK SLC Devices or use Table 3-4 if install-
ing SD SLC Devices For the IFP-2100/ECS, the worst case current draw is listed for the panel, addressable
devices, and all SBUS expanders. Fill in the number of addressable devices and expanders that will be used
in the system and compute the current draw requirements for alarm and standby. Record this information in
the current draw worksheet on Line A.
2. Add up the current draw for all auxiliary devices and record in the table on Line B.
3. Add up the current draw for all notification appliance loads and record in the table on Line C.
4. For notification appliances and auxiliary devices not mentioned in the manual, refer to the device manual for
the current ratings.
5. Make sure that the total alarm current you calculated, including current for the panel itself, does not exceed
9.0 A. This is the maximum alarm current for the IFP-2100/ECS control panel. If the current is above 9.0 A
you will need to use a notification power expander(s) such as the 5496 or the RPS-1000 intelligent power
expander, to distribute the power loads so that the IFP-2100/ECS or the power expanders do not exceed their
power ratings. Refer to the current draw worksheets provided with the 5496 or the RPS-1000 manuals so
you do not exceed their power ratings.
6. Alternatively, you may network additional IFP-2100/ECS or RFP-2100s to get additional power.
7. Complete the remaining instructions in the appropriate current draw worksheet for determining battery size
requirements.

Current Draw Worksheet for IDP SLC Devices

Use Table 3-2 to determine current requirements during alarm/battery standby operation when IDP SLC devices
are installed. You can install up to 159 IDP sensors per loop (2100 points max per panel) and 159 IDP modules
per loop (2100 points max per panel). Copy this section if additional space is required.
