Smoke detectors going off everywhere. This is new building and first time turn on the heaters. I think when turn on the heater for first time usually burn off some of dust and oil residue burn and smokes little while. My question is how to bypass alarm until burn off all the residue in the heaters? Smoke detector shuts HVACs off before burn off residue.
If I have to call contractor which one Fire Protection, HVAC, Electrician.

What kind of heaters? What kind of building? Gaspacks? Electric unit heaters? Gas unit heaters? Fan powered boxes with reheat? Is this a Warehouse? An Office building? A manufacturing facility? A little more information would be helpful.

Are they all alarming or just one? U may actually have a serious problem and only attributing it to "dust"
Depends how the system is wired...into a alarm/fire pane? talk to them...they may be able to put it temporary into test mode where u can reset when it alarms. They may also request you contact the installing HVAC contractor.
THE DETECTOR ARE THERE TO SAVE LIVES....in 11yrs of service i have only gone on a handful of nuances calls...most alarms turned out to be actual problems.

As for the problem
A)I'm a sparky, not a fire sparky, but HOW MUCH SMOKE is coming off these things??? Smoke detectors are reasonable intelligent, ie they don't go off at a slight puff of smoke, it usually takes a decent amount. (Assuming it's not some kind of VESDA system)
and B) If you bypass part of the fire detection system and are unlucky enough for something to go wrong, then the fine you'll cop will be so astronomical it will need to be printed over two sheets of paper to fit the whole amount in.
Oh, and the fire protection guys will be pretty useful to get out, to answer your question. Depending on your system they might be able to narrow it down to an individual unit causing the problemThe DDC system... guilty until proven innocent

best way i found when starting a new unit [when it is a rtu ] is leave the panels off of blower compartment and heat xchanger if possible unhook blower contactor and fire it up. works pretty good for most units.work to live not live to work.
