DESIGN REFERENCE MANUAL
See NFPA 80, Fig. B-51 as to location and quantity of smoke detectors required.
Duct detectors must be installed when they meet the conditions listed in NFPA
72E and NFPA 90A-14, Sec. 4-2 through 4-4.
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.
Interface Between Direct Digital Controls and Fire Alarm System
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.
Designer shall identify the estimated quantity of dry contacts needed for the fire alarm system on the fire alarm drawings.
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.
Elevators shall capture only when the elevator lobby, elevator hoistway or elevator mechanical room detectors alarm (see NFPA 72, Chapter 3-7.3.1).
The elevator electrical shunt trip shall not be controlled by a water flow switch in the sprinkler system.
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.)
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:
Laboratories (where required) (Heat detectors are preferred, but a variance is required.) Mechanical rooms (except high temperature areas) Elevator lobbies
