Can Fire Alarm System Smoke Detectors Replace 120 VAC Smoke Detectors?

When it comes to renovations of multi-residential buildings or transient occupancies (hotels, SROs, etc.), one of the considerations that designers of record has is long term costs to the owner.  An item the often gets overlooked are the living unit smoke detectors.  Most assume that local, 120 vac powered (AKA ‘single station’) smoke detectors are either their only option,  their least expensive option or that this type of detector is required by code.  None of these assumptions are true, especially for the long term impact to the owner.

Multi-unit residential occupancies will usually have a fire alarm system installed for common area protection, so it makes sense to see if that system can be extended into the residential spaces in order to simplify life safety installation requirements.  Modern fire alarm system smoke detectors can be programmed to function like a single station smoke detector, but with the added feature of being monitored for functionality.  This gives the building owners added protection for their occupants and can even reduce their insurance rates.

The perception of being more costly to install may keep designers and contractors from using system detectors in this application.  However, initial costs should be similar, since sleeping areas now require smoke detectors to be powered by the building’s electrical system.  Extending the low voltage fire alarm circuit into the living space rather than finding a new power source then installing a separate conduit saves on equipment and labor, as many municipalities do not require fire alarm circuits to be in conduit.

The bottom line is where new construction or major renovation is involved, utilizing the new technology modern fire alarm systems offer is not only a cost efficient way to meet code, it’s also the most reliable solution to give occupants early warning of fire.
