1. Total does not include isolator devices or accessory bases.
2. If using 24 VDC aux power only. No standby or alarm current for battery calculation if using 24 VAC, 120
VAC or 240 VAC.
3. If using door holders, you do not need to consider door holder current for alarm/battery standby, because
power is removed during that time. However, during normal operation, door holders draw current and must
be included in the 9.0A total current that can be drawn from the panel.
4. Use next size battery with capacity greater than required.
5. Maximum SBUS address capacity is 63 SBUS modules. The practical limit is determined by the amount of
SBUS bandwidth consumed by each SBUS module. See section 4.10.2.
6. The FACP can only support 2 devices w/LED’s on. The current draw has been added to the panels alarm
current.
D Total current ratings of all devices in system (line A + line B + C) mA mA
E Total current ratings converted to amperes (line D x .001): A A
F Number of standby hours H
G Multiply lines E and F. Total standby AH AH
H Alarm sounding period in hours. (For example, 5 minutes = .0833 hours) H
I Multiply lines E and H. Total alarm AH
