Each terminal connection shall be identified as it is in the panel and related directly to the wire by circuit number that is supposed to connect thereto.

D. Calculations

1. Battery Calculations

a. Provide complete battery calculations for both the alarm and supervisory power requirements. Ampere-hour requirements for each system component shall be submitted with the calculations.

b. Calculate standby battery requirements for new batteries per manufacturer’s installation requirements including all factors for aging, etc.

b. Provide calculations that show that the total load for each remote power supply or FACP power supply is 75% or less of its full load capacity.

c. Where space is available on each fire alarm floor plan, provide these calculations for the circuits on that floor plan.

b. Provide calculations such that the total losses for each individual circuit are no more than 1 dBA with all devices assumed at the end of the circuit.

c. Provide calculations that show that no individual speaker circuit is loaded beyond 75% of its capacity. A speaker circuit’s capacity is defined as no more than 1 dBA loss or the wattage limitation of the speaker notification module, whichever is less.

d. Provide calculations that show that the total load for each amplifier is 75% or less of its full load capacity.

e. Where space is available on each fire alarm floor plan, provide speaker loading matrix for the devices on each floor plan. This information shall indicate the number of speakers on each tap setting for each audio circuit with the total wattage used for the circuits on each floor plan.

4. Voltage Drop Calculations

a. Provide voltage drop calculations by the use of either a lumped load calculation (all devices assumed at the end of the circuit) or by the distributive load calculation method whereby voltage drops are calculated for each device.
