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
Dimensions of recessed lighting
Structural Systems
Steel yourselves
Concrete systems
Most restrictive
Heating and A/C symbols
Mechanical Plans from the Engineer
You need the duct sizing and register locations
Air systems: how they work
Parts of a furnace: this is what goes in your mechanic al room
Supply air diffusers
Linear diffusers and return grilles
Fire codes See NFPA 72 Three parts: –Initiation –Notification –Control
Manual Pull Stations By each required exit
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 internallyceiling 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)
Hose cabinets By required exits
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
Rules of Thumb For schematic layouts Use and engineer or other consultant for final layout
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
