3.6 Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery
requirements (Table 3-2).
3.6.1 Worksheet Requirements
The following steps must be taken when determining 5600 current draw and standby
battery requirements.
1. For the 5600, the worst case current draw is listed for the panel and all address-
able devices. Fill in the number of addressable devices that will be used in the
system and compute the current draw requirements for alarm and standby.
Record this information in the Current Calculation Worksheet at Line A.
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 appliance circuits and auxiliary devices not mentioned in the man-
ual, 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 2.0 A. This is the maximum alarm current for the
5600 control panel.
If the current is above 2.0 A you will need to use a notification power expander(s)
such as the Silent Knight 5495 power module to distribute the power loads so that
the 5600 or the power expanders do not exceed their power rating.
6. Complete the remaining instructions in the Current Calculation Worksheet for
determining battery size requirements.
