in a 3 unit building should the detectors be on the house meter or each unit?
Thanks JW good informationeach unit unless part of a call system
That is what I thought.If the individual meters will be turned of when unoccupied, then they MUST be on the building meter so they are ALWAYS active as long as ANY unit is occupied.
Thanks JW they will be hard wired and not part of a security company they are only smokes and co2 and must on a lighting circuit on the house panel I think.If we are talking residential units then each unit will be independent of each other as well as any smoke alarms.
If the smoke detectors are part of a system that calls the fire department then they will be a low voltage system and will include all units and be installed by a fire alarm company.
If I understand what you wrote, you are saying that if there were say 12 apartments in a building and the only occupied one was on the fourth floor, THAT would be the only smoke alarm that had to be "active" even if fire broke out on the lower level and burned through the intervening floors before the smoke detector/alarm went off. Good luck saving those occupants.
The 4TH FLOOR is equipment only.That would be the only way to protect the occupants of the fourth floor if there were a fire on the lower levels, but I would assume a usage such as that would also require a fire suppression system.
Okay to clarify the building I am working on is 3 units, one being an efficiency the other two are one bedroom units all on separate meters plus house meter all are sub panels and the main panel combo meter box serves as the main panel with 4 100 amp breaker for each panel it requires that the smoke alarms be on the house panel and all smoke alarms through the whole building. They will not be attached to a security or fire notification system.
This is awkward, but...
