Do commercial smoke detectors have to be replaced every 10 years like regular house hold smoke detectors, or are they replaced when they do not operate properly anymore by sensitivity or not activating on a smoke test, because that would be costly.
no, that code only applies to households, specifically “one and two-family dwellings”, like a house or a duplex. in a commercial setting smoke detectors are tested yearly and re-calibrated or replaced when they’re outside of their listed sensitivity range.
We have a site where the smoke detectors are 35 years old. As long as they still work, they cannot be forced to replace them. The system is long due for an upgrade and they finally this year agreed to start that process!
If you have a system sensor i3 or a system sensor 2100 do these need to be replaced every ten years or does that not apply to the one and two family rule? They are installed in a residence as part of a security system.
I would think not. As long as they are cleaned regularly and tested regularly, commercial photoelectric detectors can last up to thirty years. I think the rule only applies to residential-style smoke alarms, because the majority of them are ionization.
The good thing about smoke detectors tied to a security system is that you don’t have to spend upwards of $40 a year on nine-volt batteries.
ok thanks
