The life safety systems have been designed with applicable seismic codes 780 CMR Chapter 16 and
NFPA 13-2013.
901.2.1.1A. II SEQUENCE OF OPERATION OF ALL FIRE PROTECTION SYSTEMS AND
OPERATIONS
Fire Alarm Systems:
Fire Alarm systems shall be multiplex, fully addressable and include initiating devise, signaling devices
and all required, batteries, modules, power supplies, relays, wiring, and other equipment required for
complete system operation. The fire alarm system will be equipped with a 60-hour standby battery back-
up plus 10 minutes alarm. The system shall be installed in accordance with NFPA 72 and include the
following:
Fire Alarm Control Panel (FACP): Control panel shall be tied into 2 dedicated phone lines via a
master box mounted on the outside of the building to notify the local fire department. FACP will
be located in the electric room (Rm 136) with a remote annunciator panel located at the main
entry.
Tamper Switches: Sprinkler system monitoring
Flow Switches: Sprinkler system monitoring
Annunciation: Remote annunciator at main entry
Manual Pull Stations: Located at all exit points within the building
Smoke Detectors and Heat Detectors: Located in compliance with code
Duct Smoke Detectors: All HVAC equipment as required by code
Carbon Monoxide Detectors: All areas subject to exposure (alarm only)
The existence of a ground fault, short, removal of a detector head, communications failure, failure of any
component or wiring that might impair the function of the system, or other related system fault will
automatically indicate a trouble notification.
Fire Sprinkler Systems:
The system consists of a main wet alarm valve, and a dry alarm valve supplying the automatic sprinkler
systems. The alarm valves shall include an electric bell, any flow through the system will initiate a main
alarm including a signal to the FACP and electric bell.

The wet pipe sprinkler system shall be a single zone. The sprinkler heads are quick response type. All
heads come equipped with heat activated frangible bulbs or fusible links. When exposed to heat above
the listed temperature the bulb shall burst and allow the head to open, water to discharge to extinguish
the fire and initiate a zone flow alarm at the main alarm valve.
The dry pipe sprinkler system shall be a single zone. All heads are quick response type and come
equipped with heat activated frangible bulbs or fusible links. When exposed to heat above the listed
temperature the bulb shall burst and allow the head to open, air shall discharge opening the dry pipe
valve allowing water to flow through the pipe and discharge on to the fire, a zone flow alarm shall be
initiated at the main alarm valve.
901.2.1.1A. III FINAL SYSTEM ACCEPTANCE TESTING CRITERIA
The systems shall be tested in accordance with NFPA 90A, NFPA 72, NFPA 13, NFPA 24, NFPA 25 and
as specified in the construction documents.
1) Water supply
a) Flushing: Underground / exterior service entrance flushed at a minimum velocity of 10
fps in accordance with NFPA standards 13 and 24. The contractor shall notify the Water
and Fire Departments prior to testing the entire new system.
2) Sprinkler System
a) Hydrostatic Testing: The interior system will be hydrostatically tested at 200 psi for 2
hours in accordance with NFPA 13, 25.2.1.1.
b) Operational Testing: Water flow switches and associated alarm systems will be tested
by water flow through the inspector’s test assemblies in accordance with NFPA 13,
25.2.3.1.
c) Main Drain Test: A flow test will be performed on the main drain valve and recorded on
the Contractor’s test certificate in conformance with NFPA 13, 25.2.3.4.
d) Backflow Preventor Flow Test: The double check valve assembly will be flow tested in
conformance with NFPA 13, 25.2.5.
