SECTION 13850 - FIRE ALARM SYSTEM DESIGN

PART 1 - GENERAL

1.1SUMMARY

  1. This Section includes the design, preparation of installation documents, for a microprocessor controlled, intelligent reporting networked fire alarm equipment required to form a complete, operative, coordinated system.
  2. The fire alarm system shall comply with requirements of latest edition of the NFPA Standard 72 for Protected Premises Signaling Systems except as modified and supplemented by this specification. The system shall be electrically supervised Class A Style 7 and monitor the integrity of conductors.
  3. Alarm and trouble signals from each transponder shall be digitally encoded by listed electronic devices onto the looped fiber optic backbone addressable communication system.
  4. Alarm, trouble, and supervisory signals from intelligent reporting devices shall be encoded onto the Signaling Line Circuits.
  5. The system shall be an active/interrogative type system where each transponder is repetitively scanned; causing a signal to be transmitted to the local fire alarm control panel node indicating that the transponder and its associated initiating device and notification appliance circuit wiring is functional. Loss of this signal at the local fire alarm control panel (FACP) shall result in a trouble indication on both the FACP display and at the network display, as specified hereinafter for the particular input.
  6. The system shall be arranged such that not less than 25 percent additional transponders may be inserted into network communication loop.
  7. The FACP and peripheral devices shall be manufactured 100 percent by a single U.S. manufacturer (or division thereof).
  8. The system and its components shall be Underwriters Laboratories, Inc. listed under the appropriate UL testing standard as listed herein for fire alarm applications and shall be in compliance with the UL listing and meet FMG approval.
  9. The Fire Alarm and Security Installer shall employ NICET (minimum Level II Fire Alarm Technology) technicians on site to guide the final checkout and to ensure the systems integrity.
  10. Fire Alarm System Designer shall prepare and submit necessary documentation, payments etc. as required to obtain the required permits. Be responsible to ensure Fire Alarm System design is acceptable and will be approved by the Authority Having Jurisdiction.
  11. Alternate: Provide a representative to assist with testing and commissioning of the completed system.

1.3SYSTEM DESCRIPTION

  1. General
  2. Basic Performance: Each signal line circuit (SLC) loop shall be wired NFPA 72 Style 6 (ClassA).
  3. Initiation Device Circuits (IDC) shall be wired Class B (NFPA Style B) as part of an addressable device connected to the by the SLC circuit.
  4. Notification Appliance Circuits (NAC) shall be wired Class B (NFPA Style Y) as part of an addressable device connected by the SLC circuit or a panel circuit.
  5. Alarm signals arriving at the main FACP shall not be lost following a primary power failure.
  6. Provide device isolators so that a maximum of 10 devices can be lost with a system wire to wire short. Isolators shall be located a minimum of 8 feet above the floor with easy viewing from the floor. They shall not be attached to the same conduit or box as the manual pull stations.
  7. The Signaling Line Circuits (SLC) shall be in a ring (loop) configuration. The ring shall provide Class A (Style 6) operation. Communication between nodes shall be through fiber optic cables.
  8. The fire alarm and detection system communications shall be via a peer-to-peer, deterministic, token passing communication method. Collision and recovery or poll-response methods that can not be shown to have deterministic performance are not permissible alternates.
  9. Operation of the network shall not rely on any one master controller or other central component that, when failed, shall reduce or entirely interrupt operation of the remainder of the network.
  10. Failure of any node shall not cause failure of any other node or loss of communication among surviving nodes.
  11. If a group of nodes becomes isolated from the rest of the network, that group shall continue to function with common interactions of monitoring and control remaining intact. The network shall be notified with the exact details of the loss.
  12. When a node is added or removed from any portion of the network, whether due to circuit fault or equipment failure, the network shall automatically re-configure to insert/remove the affected node.
  13. Each node shall be field configured to support communications at 1200, 9600, 19200, and 38400 BPS (bits per second). Selection of communications speed shall be determined by site conditions.
  14. Equipment in the network communication path shall maintain efficient 1/2 bit data regeneration techniques that allow information to be passed from node to node with minimum time loss. Equipment that requires buffering of data at each node before being repeated shall not be acceptable because such techniques cause delayed system response.
  15. The network shall utilize dedicated fiber optics signaling. Fiber optics interface equipment shall be UL listed or FMG approved for compatibility with the control equipment.
  16. Signaling Line Circuit Fiber Optic Specification & Guidelines
  17. General
  18. Fiber optic cable used within the Plant shall be tight-buffeted, multi-media indoor/outdoor riser rated, breakout, plenum rated cable.

  3. Where cables are run exposed they shall be run using bridal rings and be run directly below the top cord of truss as close to the roof as possible.
  4. When fiber cable/copper wire is run down from truss to the Cabinets it shall be run in 3/4inch rigid galvanized conduit.
  5. Appropriate care and installation techniques shall be used to ensure that the manufacturer’s specifications for minimum bend radius and maximum tensile rating and vertical rise are not exceeded.
  6. Splices are not allowed in the fiber optic cables. Fiber patch panels are acceptable.
  7. The fiber optic cable shall have an end-to-end loss, including losses through the patch panels at each end and 100 foot jumper cable (on each end), of less than 4.0dB. This shall include a maximum loss of 0.6 dB (total both ends) loss through the connectors and the dB rated loss (0.92dB/1000ft at 850nm and 0.305dB/1000ft at 1300nm) due to the length of the cable.
  8. Cables not meeting the manufacturers and DaimlerChrysler’s test requirements shall be replaced at no additional cost to the DaimlerChrysler or penalty to the scheduled project completion.
  1. Fiber Optic Terminating
  2. Each fiber shall be terminated with ceramic ferrule ST connectors.

  4. Insertion Loss for fiber optics connectors shall be less than 0.5 dB.
  5. Labeling
  6. Each fiber optic cable shall be permanently imprinted with a typewritten identification tag. Identification tags must be placed within 2 feet of each end of each cable. Label cable even when within conduit or Inner duct. The labeling format is listed in AppendixA.

2)Conformance to manufacturer’s loss specifications for each reel of cable must be shown and approved by Owner prior to the start of installation.

  1. Post installation testing

1)End-to-end testing shall be performed at both 850 and 1300 nm in one direction (From Data Center to cabinets) on each strand of cable using an OTDR approved by the Owner. Testing shall be performed using a “100-foot jumper cable” on both ends, of cable being tested, to show db loss through connectors on both ends.

2)The loss of each strand and terminations shall not exceed 4db end to end and shall be documented.

3)Hard copies of each OTDR trace shall be provided. Replace cables and/or terminations not meeting DaimlerChrysler Corporation standards prior to system being accepted and the Fire Alarm and Security Installer submitting documentation for review.

  1. Insertion loss testing

1)End-to-end testing shall be performed on each length of cable using a fiber optic power loss meter set approved by the Owner.

2)The end-to-end attenuation of each cable at 850 and 1300 nm in both directions shall be documented. Provide 2 MICROTEST fiber solution kits P:8080-02 (or latest edition) to owner prior at start of project.
