Appendix B - Power Supply & Battery Calculations (
Selection Guide
)
Use the form below to determine the required Main Chassis and Secondary Power Supply (batteries).
Total Current Requirement:
ALARM (B)______ Amps.
Battery Capacity Requirement:
([STANDBY (A)______ ] X [(24 or 60 Hours)___ ]) + ([ALARM (B)______ ] X [
*
Alarm in Hr.] _____) = (C)______AH
Battery Selection:
Multiply (C) by 1.20 to derate battery.
Batteries: BA-110(10AH),
BA-117(17AH) will fit into the BPS-1100.
*
Use
0.084
for five minutes of alarm or
0.5
for thirty minutes of alarm as a multiplier figure.
IMPORTANT NOTICE
The main AC branch circuit connection for Fire Alarm Control Unit must provide a dedicated continuous power without provision of any disconnect
devices. Use #12 AWG wire with 600-volt insulation and proper over-current circuit protection that complies with the local codes. Refer to
Appendix A - Module Specifications And Features on page 30
for specifications.
