Devices and equipment for fire protection service shall be of a make and type listed by the Underwriter's Laboratories Inc. in the UL Fire Protection Equipment Directory or approved by the Factory Mutual System in FM APPROVAL GUIDE, unless otherwise specified. In the publications referred to herein, the advisory provisions shall be considered to be mandatory, as though the word "shall" had been substituted for "should" wherever it appears; reference to the "authority having jurisdiction" shall be interpreted to mean US Army Corps of Engineers Center of Expertise for Aircraft Hangar Fire Protection.

Foam Concentrate Storage Tank must be a vertical, closed cell double-walled , high density cross-linked polyethylene storage tank compatible with the required concentrate. Tank capacity must be the volume required to fully submerge the inductor dip tube plus the design volume to operate the foam generators for not less than 15 minutes or discharge at the hydraulically calculated waterflow rate and 130% of the nominal concentrate injection rate. Design the inductor to 115% of the nominal injection rate. The inductor dip tube must enter through the top of the tank, and no taps are permitted in the bottom or sides of the tank. Provide a closeable fill opening and vent assembly. Provide either a translucent shell or clear vertical window to indicate fill level with permanent capacity markings at least every 50 gallons. The capacity markings will not include the unsuckable amount of concentration at the bottom of the tank. Mount concentrate tank on a 2 inch concrete housekeeping pad. The double wall tank does not require spill or secondary containment. A second foam concentrate tank or reserve concentrate supply is not required.

The foam proportioning must be by a single foam inductor for each foam-water riser. Inductor must, through a venturi, take concentrate and

SECTION 21 13 25.00 10 Page 5 proportion such concentrate into the flow steam reliably at the designed system flow rate. Inductor must be specifically tuned for the system required flow rate, inlet pressure, back pressure, concentrate type, proportioning ratio, and lift height (at the near empty tank level). The inductor must be equipped with the exact orifice at the entry of the foam pipe. Off the shelf pre-tuned generic model inductors are not permitted.

Shop drawings must be accompanied with an inductor datasheet fully annotated with the flow rate, inlet pressure, back pressure, and concentrate lift height (at the near empty tank level). Inductor will be fitted with a low loss bronze or brass check valve assembly by the manufacturer that is included in the device's hydraulic design.

An automatic flow control valve must be provided with trim package for electric releasing, remote re-setting, and opening/closing speed control.

Provide flow control vavle in accordance with UFC 4-211-01. In addition to automatic operation, arrange each valve for manual release at the valve.

Trim piping must be factory configured and installed. The manual release for the flow control valve shall be installed no higher than 1.5 m above finished floor. Flow control valve provided must include the manufacturer's minimum pressure drop across the valve for the features indicated in UFC 4-211-01.

Prepriming of any foam solution piping is NOT acceptable. All solution piping must be slopped to be self-draining back to the riser. During commissioning, the responsible FPE must seal or otherwise install tamper proof guards on the pressure regulator adjusting stem and the two small globe valves on the speed control assembly. It is crucial these settings not be changed after commission; least the system may be impaired.

Safety-wire these devices in those positions and label them "DO NOT ADJUST". Any other trim valves which must be open or closed for the automatic flow control valve to function also must be safety wired in position.

Provide foam stop stations of the "dead-man" type. The stop stations must be used in conjunction with valves and equipment that will prohibit or stop the discharge of foam/water from the foam suppression system. The stations must have distinctive signage at each device. Provide a red mushroom type push button and include the word "PUSH". Colored portions of tamper cover must be blue and lettering on the cover must be "STOP"; the words "FIRE", "ALARM", or "AGENT" must not appear on the cover. A manual foam stop station will be provided at each manual foam releasing station. Once depressed, and so long as the button is held down, the stop station will prevent/stop discharge from the foam system regardless of whether or not the foam system was activated automatically or manually and whether or not the activation occurs prior to or after the stop station is pressed and held. Unless the foam system control panel (FSCP) has been reset and all activation alarms (manual and automatic) have been cleared; when the foam stop station button is released, the FSCP will instantaneously restore system operation and foam discharge. When the foam stop station button is depressed under full flow, the time to fully close the flow control valve will not exceed 15 seconds. The time for the flow control valve to fully open upon release of the foam stop station button will not exceed 5 seconds. Manual foam stop stations will be protected from mechanical damage and water infiltration (minimum NEMA 4). Manual foam stop stations will be provided with a clear plastic tamper cover that must be lifted prior to actuating the station. Conduits will enter the station back box from the bottom. Back box and conduits will not be placed in front of

Where manual stop stations and foam releasing stations are provided at an exit door, they will be located on opposite sides of doorway from fire alarm manual pull station. Where not located at an exit door opening, the manual stop stations and foam releasing stations will be located at least 1524 mm apart from the manual fire alarm pull station.

Provide two separate but adjacent 610 mm high by 508 mm wide metal signs.

There will be no more than 304 mm of separation between the two signs. The words "FIRE", "ALARM", or "AGENT" will not appear on these signs. The sign for the manual releasing station will have a yellow or lime-yellow background with "START FOAM SYSTEM" in red lettering not less than 76 mm high. The manual release station with tamper cover will be located on the lower center portion of the sign. The word "START" will be written in minimum 1 inch high green lettering placed directly above the activation station. The sign for the manual stop station will have a white background with a minimum 1/2 inch wide blue border with "STOP FOAM SYSTEM" in blue lettering not less than 3 inches high. The manual stop station with tamper cover will be located on the lower center portion of the sign. The word "STOP" will be written in minimum 1 inch high red lettering placed directly above the manual stop station.

FSCP FSCP must be Det-Tronics Eagle Quantum Premier Fire Detection/ Releasing System, must be furnished complete with Safety Systems Software (S3) configuration/logic programming/diagnostic tools software package including USB dongle key and RS232 cable. FSCP alarm, supervisory, and trouble signal reporting to the Fire Alarm Control Panel must be via discrete dry contact output points. Modular type panel installed in a surface mounted NEMA 4 painted steel cabinet with hinged door and cylinder lock. All detectors must be listed for use with that panel. IR detectors must be networked with the panel so that during commission IR detectors can be calibrated from the releasing panel. The FSCP must provide a real time display of current IR levels at any detector, have the ability to set the detector sensitivity for each detector from the panel, be able to download detector level log history, have remote test and diagnostics capability (manual self-test, lens dirty, sensor failure, power out of tolerance, device non-responsive), and remote setup and programing of detector options (lens heater power level, detector alarm LED function, alarm latching or non-latching, device address, sensitivity level, timing and gate count for alarm). FSCP must be electro-magnetic interference/radio frequency interference (EMI)/(RFI) tolerant and rated to SIL level 2 capability (IEC 61508), a safety assessment evaluation which evaluates critical fault paths, redundancies, and statistical measurement/prediction to ensure a specific level of long term reliable performance and stability to co-exist with aircraft radar systems.

Optical flame detection system shall be the X3301 Multi-spectrum IR Flame Detector manufactured by Det-Tronics and will use triple infrared (IR) flame detectors listed/approved for the expected fuel hazards in the hangar bay. The detectors will be immune to radar and radio frequency emissions.

Provide shielding for the detectors and their circuits from radio frequency interference. All circuiting from the FACP or FSCP to the detectors will be shielded, and shielding will be grounded at one end. A single optical flame detector alarm signal shall result in a latched fire alarm output to the fire alarm notification system. Any two optical flame detectors in alarm simultaneously shall result in a latched foam suppression release.

Detectors must be mounted in accordance with their listing at approximately 2440 mm above the finished floor of the hangar. The specifics for each design must take into account facility construction, type of aircraft, SECTION 21 13 25.00 10 Page 7 aircraft configuration and positioning, fixed and mobile equipment within the aircraft servicing area, and all other relevant factors. Do not mount optical detectors in inaccessible locations. The detectors will be angled and blinds will be provided such that the cone-of-vision does not extend more than 1524 mm outside the hangar bay. The horizontal and vertical axis of the detector determined during commissioning will be permanently marked on each detector. The optical flame detectors will be installed with 1524 mm of flexible conduit to allow for any minor adjustments during testing or changes in mission of the hangar. Provide a sufficient number of optical flame detectors such that a fire at any position within the hangar bay will be within the range and cone-of vision of at least two detectors. With the exception of a manual foam release station, the cross-zoning of two optical flame detectors in the hangar bay is required to release the foam suppression system.

Provide blue beacons not less than 400 cd (208/120VAC) powered from a dedicated emergency panel provided in accordance with UFC 3-520-01. The FSCP will control beacon initiation. A backup power supply or supervision of the power supply feeding the beacons is not required when fed from the dedicated emergency panel. Beacons will be mounted 6.1 m to 9.1 m above the floor of the hangar bay. Provide additional beacons where at least one beacon is not viewable from normally occupied areas of the hangar bay.

Design will take into account facility construction, type of aircraft, aircraft configuration and positioning, fixed and mobile equipment within the aircraft servicing area.

Provide a 2-position non-key operated switch located within the FSCP enclosure, that when activated disables the releasing function of all optical flame detectors in the hangar bay through programming at the FSCP.

When the switch is placed in inhibit mode, only the releasing functions of the optical flame detectors are disabled while leaving all other functions of the FSCP operational. Monitor the inhibit switch at the FSCP. Provide supervisory signal to the receiving station indicating the optical flame detectors are inhibited, a trouble signal is not permitted. Label the switch "INHIBIT OPTICAL FLAME DETECTION". Provide engraved labels on the inhibit switch indicating when the optical flame detectors are in "NORMAL" or "INHIBIT" mode.
