DESIGN REFERENCE MANUAL
Equipment that has been by-passed in software shall not change state of condition during a "reset."
Signaling devices shall be completely deactivated by pressing "signal
Audibles shall be placed so that they can be heard a minimum of 15 decibels above the ambient decibel level in all locations (refer to NFPA 72G and ISBC16.705(12).
Amplifiers shall be a minimum size of 100 watts, except in dual channel applications where the elevator channel may use 25 watt amplifiers. Amplifiers shall have redundant back-up amplifier(s) that automatically transfer. They shall be sized using calculations of:
One (1) watt per interior speaker. (In restrooms and small rooms set taps at ¼ watt.)
Two (2) watts per outside and mechanical room speaker.
Each audio amplifier shall be sized to include 20 percent spare capacity per circuit for future connection of audio speakers.
Outside speakers shall be located at all main entrances and shall be on a circuit separate from interior speakers.
Strobe intensity shall be determined by ADA requirements.
All strobes within site shall be synchronized.
Each strobe circuit shall be sized to include 10 percent spare capacity for future connection of strobes.
Each strobe circuit shall be capable of being individually controlled in software.
Each fire floor and fire zone shall have individual strobe circuits.
Smoke Dampers: SELECT-A-SWITCH, Model SL53413-6-BG
Place damper indicator lights in corridors whenever possible.
Beam Detectors: If beam detectors are proposed, design must be reviewed by FSG-Fire Safety Department for appropriate application, maintenance and accessibility. Provide a beam detector test switch for each detector.
Each floor shall have a separate conduit feed.
