2. Provide batteries with ampere - hour capacity rated at 150% above the minimum required
calculated value (24 hours normal operation plus 5 minutes alarm operation).
F. Voltage Drop Calculations:
1. Provide voltage drop calculations using the lumped load calculation method (all devices
assumed at the end of the circuit). Use the current consumption of the device at its lowest
operating voltage rating.
2. Provide calculations showing that with a supply of 24.0 volts, measured at the point of
connection to the notification circuit, the last device shall have no less than 21.6 volts
measured across its terminals. The last device shall be the device which has the lowest
voltage measured across its terminals as determined by measurements taken from the
FACP to the last device in each leg of a Class A circuit.
3. Size all wiring for a 20% increase in the number of devices and conductor length added
to a circuit will not lower the voltage drop at the last device below 21.6 volts as indicated
in paragraph 1.02 (E) (2). Include this calculation with the submittal.
4. Calculations shall prove that no individual initiating, signaling or notification appliance circuit
is loaded more than 80% of its capacity. Calculations shall prove that the total connected
load for each remote power supply or FACP power supply is 80% or less of its
capacity.
G. Field quality-control test reports.
H. Operation and maintenance data.
I. Submittals to Authorities Having Jurisdiction (AHJ): In addition to distribution requirements
for submittals specified in Division 1 Section "Submittals," make an identical submittal to authorities
having jurisdiction. To facilitate review, include copies of annotated Contract Drawings
as needed to depict component locations. Resubmit if required to make clarifications or
revisions to obtain approval. On receipt of comments from authorities having jurisdiction,
submit them to Architect for review. If special permit fees are required for AHJ review and
approval, this cost shall be included in the fire alarm contractors bid.
J. Documentation:
1. Approval and Acceptance: Provide the "Record of Completion" form according to
NFPA 72 to Owner, Architect, and authorities having jurisdiction.
2. Record of Completion Documents: Provide the "Permanent Records" according to
NFPA 72 to Owner, Architect, and authorities having jurisdiction. Format of the written
sequence of operation shall be the optional input/output matrix.
1.05 QUALITY ASSURANCE
