smoke detectors in commercial bathrooms

[mtnelectrical]

Have you ever installed SD inside bathrooms?

Always strobes but there was always drama over proper location where strobe can be seen from in the bathroom.

Sounds like a building code question to me. Do they call them smoke detectors in a commercial environment?

Yes sir. Montclair, Verona, Cedar Grove, The Oranges, Maplewood areas.. and of course Newark ....:smile:

I have never installed a smoke detector in a commercial building, they are only required in residential around here...

Yes.
Smoke detectors may be required in a bathroom, for that matter, one could be required anywhere/everywhere.

For example in a hospital for smoke damper control, the damper can be controled by a dedicated duct detector (which are prone to false alarms) or total area detection can be used to close the damper. The total area detection requires a smoke detector in every room fed by the HVAC system, including restroom/toilets.

Though NFPA 72 does state that smoke detectors shall not be installed in areas that are too extreme, so where there are showers the somke detectors may not want to be used due to false alarms (steam looks like smoke to the detector).

couldn't you install the ionization-type detector in this case?

Ion smokes are still sensitive to high humidity and are not as good as photo types oveall. Also, I would not mix types as having a few ions in some rooms and photos in the rest of the facility. It would be hard for the facility guys to know which is which when they need cleaning/replacement.

Also, there is such a small percentage of the air flow going to a small toilet/shower room relative to the rest of the HVAC zone that other detectors will sense the smoke first anyway.
