Equipment above suspended ceiling

[aeroo]

Hi! Maybe this question is more appropriate for the "Engineering Codes, Standards & Certifications" section but I'm not sure which standard I need...and I thought the HVAC people might have the best knowledge of standards that apply to plenum space or suspended ceiling space. I am working on an OEM enclosure design that will be located above the suspended ceiling which will house a projector, some electronics, mirror, and a motor that will drop the mirror into a room to reflect an image onto a screen. The weight of the enclosure and equipment will then be suspended from the concrete ceiling using expansion bolts. This will be sold and installed in various buildings in the United States. Do you guys know what certification this will need in order to be installed in US buildings? New and existing construction. Would it be just a UL mark? NFPA testing? or some other governing body that a facilities engineer would ask for or require before installation? Thanks!

@ Aronsta,
I am not sure what state you are now but you intend to sell it in the whole of USA,Right? there's no "one size fits all for your product. My experience in hanging equipment in CALI, you need OSHPD approved mounting procedure if its for school or hospital. the best you can do is provide the info and let the designer do the math. Get that monkey off your back. Seismic provisions are big Bro!

This is a structural question, not an HVAXC question.

See UL 2043. There may be others.

Best to you,

suspended from the concrete ceiling using expansion bolts

Your product will only work when suspended from a concrete ceiling?

Your product will only work if expansion bolts are used?

Few things that will apply:

1. service clearances - section 306 of IMC 2012
2. Ventilation of uninhabited spaces - section 406 IMC 2012
3. Heat generation to space needs to be addressed
4. seismic bracing needs to be addresses in some areas of the US.
5. Fire rating enclosure, say if equipment is located above a fire rated ceiling, then you'd need fire rated access doors for service.
6. some electrical codes may apply, especially UL listed wiring and motors. keep in mind in the US, we run electrical wiring in steel conduits.
7. some jurisdictions may require a smoke detector if your system has a fan. SD to stop fan upon sensing smoke.
8. some local jurisdictions may require a sprinkler head if the ceiling space height is over a defined limit.

This is all I can think of.
