DESIGN REFERENCE MANUAL

    • A.

      See NFPA 80, Fig. B-51 as to location and quantity of smoke detectors required.

      • 1.11

        Air Handlers

        • A.

          Duct detectors must be installed when they meet the conditions listed in NFPA

72E and NFPA 90A-14, Sec. 4-2 through 4-4.

    • B.

      Provide a labeled test switch with LED. This test switch shall be installed for each duct smoke detector. This switch shall be installed at a mounting height of 48" to 72" above the floor.

      • 1.12

        Interface Between Direct Digital Controls and Fire Alarm System

  • A.

    The fire alarm system shall provide dry contacts as required for direct digital control (DDC) system controls to control HVAC or purge system during alarm.

  • B.

    Designer shall identify the estimated quantity of dry contacts needed for the fire alarm system on the fire alarm drawings.

    • C.

      During design development, Designer shall provide an outline of the sequence of operation for auxiliary controls from fire alarm system; i.e., smoke purge, damper control, HVAC control. A complete sequence of operation shall be included in the Contract Documents.

      • 1.13

        Elevator Controls

  • A.

    Elevators shall capture only when the elevator lobby, elevator hoistway or elevator mechanical room detectors alarm (see NFPA 72, Chapter 3-7.3.1).

  • B.

    The elevator electrical shunt trip shall not be controlled by a water flow switch in the sprinkler system.

C.

Provide a minimum of 5 control modules w/24vdc relays (w/red LED when in the alarm state.) (Primary recall, alternate recall, elevator threatened, elevator shunt and Elevator hoistway smoke damper.)

1.14

Location Of Fire Alarm Equipment

The following is a guideline* to the location of fire alarm equipment.

**This is only a brief guideline.

Photo-electric Smoke Detectors:

Corridors

Custodial rooms

Telephone Rooms

Libraries

Storage rooms

Laboratories (where required) (Heat detectors are preferred, but a variance is required.) Mechanical rooms (except high temperature areas) Elevator lobbies
