SCOPE OF SERVICES

Install Fire Suppression System in Server Room at Hamilton Hall

Project # 5623735

The project scope will be as described below to install a fire suppression system in the Hamilton Hall server room at the US Coast Guard Academy (CGA):

1. Install a Total Flood FM-200 Suppression System to provide a FM-200 minimum concentration of 7.2% by volume for Class A hazards and 9.0% by volume for Class B hazards in all areas and/or protected spaces.

2. System design shall not exceed 10.5% for normally occupied spaces with provisions for room evacuation before agent release.

3. The system shall be complete in all ways. It shall include all mechanical and electrical installation, all detection and control equipment, agent storage containers, FM-200 agent, discharge nozzles, pipe and fittings, manual release and abort stations, audible and visual alarm devices, auxiliary devices and controls, shutdowns, alarm interface, caution/advisory signs, functional checkout and testing, training and all other operations necessary for a functional, UL Listed and/or FM approved FM-200 Clean Agent Suppression System.

4. Provide two (2) inspections during the first year of service. Inspections shall be made at 6-month intervals commencing when the system is first placed into normal service.

5. The general contractor shall be responsible for sealing and securing the protected spaces against agent loss and/or leakage during the 10-minute "hold" period.

6. The system(s) shall be actuated by a combination of ionization and/or photoelectric detectors installed for maximum area coverage of 250 sq. ft. per detector, in both the room, under-floor and above ceiling protected spaces. If the airflow is one air change per minute, photoelectric detectors only shall be installed for maximum area coverage of 125 sq. ft. per detector. (Ref. NFPA No.

72.)

7. Detectors shall be Cross-Zoned detection requiring two detectors to be in alarm before release.

8. Provide all modules, connections, terminations and programming to building Fire Alarm System for control/shutdown of HVAC systems as required for the space.

All wiring shall be in EMT conduit, coordinate with Academy Fire Marshal (860- 444-8559) for FA system shutdowns. Existing FA system is by Notifier, contact TEC Controls for programming (860) 489-1456.

9. Contractor shall provide all testing, start-up and commissioning per manufacturer’s recommendations and NFPA standards.

10. Provide one year warranty on installation and equipment supplied for the suppression system.

11. Provide shop drawings in CAD 2014 indicating location of piping layout, number and type of discharge nozzles, control panel functions, number of canisters of FM-200, etc. Existing CAD drawings will be available to successful bidder upon request.

Automatic sequence of operation for the protected area within the system shall be as follows:

Actuation of one (1) detector, within the system shall be as follows:

a) Illuminate the "ALARM" lamp on the control panel face.

b) Energize an alarm bell and a visual indicator.

c) Transfer auxiliary contacts which can perform auxiliary system functions such as:

i) Operate door holder/closures on access doors,

ii) Transmit a signal to a fire alarm system

iii) Shutdown HVAC equipment.

Actuation of a 2nd detector, within the system, shall:

a) Illuminate the "PRE-DISCHARGE" lamp on the control panel face.

b) Energize a pre-discharge horn or horn/strobe device.

c) Shut down the HVAC system and/or close dampers.

d) Start time-delay sequence (not to exceed 60 seconds).

e) System abort sequence is enabled at this time.

After completion of the time-delay sequence, the FM-200 Clean Agent system shall discharge and the following shall occur:

a) Illuminate a "SYSTEM FIRED" lamp on the control panel face.

b) Shutdown of all power to high-voltage equipment

c) Energize a visual indicator(s) outside the hazard in which the discharge occurred.

d) Energize a "System Fired" audible device.

The system shall be installed by authorized/certified manufacturer installers. The system shall be capable of being actuated by manual discharge devices installed at each hazard exit. Operation of a manual device shall duplicate the sequence description above except that the time-delay and abort functions shall be bypassed. The manual discharge station shall be of the electrical actuation type and shall be supervised at the main control panel.
