Systems Coordination
All that other stuff
• Fire protection– Sprinklers– Exit lighting and signage– Smoke detection systems
• HVAC diffusers and registers • Miscellaneous electrical
– A/V, including speakers, network repeaters, (telephones), etc
– Retractable screens, projectors, etc
Smoke detectors
• One in every enclosed space• One every 41’ along corridors (for
ceilings below 24’)• Optical sensitivity• Hard-wired
Fire Detectors
• One near each required exit in exit access corridors
• Required in some specific occupancies (hazardous)
Exit signage
• Wall or ceiling mtd; can be lit internally
• At every exit door• Every 100’
Strobe lights and horns
• Spread out so that they’re visible within major egress components
• Also in bathrooms
Battery-powered lights
• Integrated with built-in lighting• Mounted on walls with battery packs
(for retrofit, or where built-in lighting is not suitable)
Sprinklers
• Use this process when working with an engineer of any sort– Start with rule of thumb for initiation layout– Read engineer’s drawings for final design,
and copy onto your RCP– Coordinate: look for interferences with
lighting, ducts, soffits and structure– note any changes and send back to engineer– 7.5’ from wall, 15’ OC both directions
Fire Extinguishers
• One near each required exit in exit access corridors
• Required in some specific occupancies (hazardous)
Other operable devices
• Hold-opens• Fire department notification• Stairwell pressurization• Smoke management systems
Wireless
• Wireless repeaters – Every 150’ within direct line of sight– 50’ through interior partitions– Not at all through masonry/exterior
walls
A/V equipment
• TV’s, projectors, etc• Sight lines are critical (for viewer and
projector)• Speakers:
– Coverage varies greatly by system– One in a room– Wall or ceiling mtd– Stereos, CD’s, etc: within the room
Don’t Forget Signage!!!
• Exit signs at all the doors (show in elevation, if you’re doing them)
• Strobe emergency lights in the bathrooms
• Emergency lights along all the paths of egress
• All need to be located in the drawings and specified
Fire Extinguishers
• Per NFPA 11• Every 150’ in assembly Use Groups
(place public areas)• Hazardous locations (kitchens)
What to do this week on your projects
• Calculations are due this week!• As for the rest of the term…
– Add all dimensions to RCPs– Add all notes– Start drawing up details– Finish up Lighting Schedule– Keep saving and labeling your fixture cuts
as you decide on them
