Prerequisites for Installation Calculating Current Draw and Standby Battery
3.5 Calculating Current Draw and Standby Battery
This section contains instructions and tables for calculating current draws and standby battery needs.
3.5.1 Worksheet Requirements
The following steps must be taken when determining IFP-300 current draw and standby battery requirements.
1. For the IFP-300, the worst case current draw is listed for the panel, addressable devices, and SLC 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.
2. Add up the current draw for all auxiliary devices and record in the table at Line B.
3. Add up all notification appliance loads and record in the table at 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 calculated, including current for the panel itself, does not exceed 6.0 A. This is the maximum
alarm current allowable.
If the current is above 6.0A, you will need to use a notification power expander(s) such as, the 5496 NAC Expander. Use the
expander(s) to distribute the power loads, so that the IFP-300 or the power expanders do not exceed their power rating.
Refer to the Current Draw Worksheets provided with the 5496 Manual to identify the ratings that do not exceed their power
requirements.
6. Alternatively, you may network the additional IFP-300to get additional power.
7. Complete the remaining instructions in the appropriate Current Draw Worksheet for determining battery size requirements.
