Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery needs
for your installation.
2.6.1
Worksheet Requirements
Follow the steps below to determine 5496 current draw and standby battery
requirements.
Filling in the Current Draw Worksheet
Refer Table 2-4 in Section 2.6.2 to complete the following steps.
1. Add up the current draw for all auxiliary devices and record in the table at Line B.
2. Add up all notification appliance loads and record in the table at Line C.
3. For notification appliances and auxiliary devices not mentioned in the manual,
refer to the device manual for the current ratings.
4. Make sure that the total alarm current you calculated, including current for the
panel itself, does not exceed 6.0 A. This is the maximum alarm current allowable.
5. Complete the remaining instructions in Table 2-4 to determine battery size
requirements.
2.6.1.1 Maximum Battery Standby Load
Table 2-3 shows the maximum battery standby load for the 5496 based on 24 and 60
hours of standby. The standby load calculations of line J in the Current Draw
Calculation Worksheet (Table 2-4) must be less than the number shown in Table 2-3
for the battery size used and standby hours required.
