Fire Alarm Requirements

[glzath]

IBC 2009 basis, section 907

We are starting off on a small building for a client that is approx 5000 SF, F-1 use, single story, no automatic sprinkler system. Am I interpreting 907 correctly that i do not need an alarm system?

I realize once we have discussions with the local FM that may change, but there appears to be no need for pull boxes, smokes, heats, etc. I guess with the bulk of my past work having been with facilities that were sprinklered or had requirements dictated by the various 907 sub-sections that it is giving me the feeling of, "Hey, where's the alarm?".

Thanks.

The only twist is monitoring of duct detectors in HVAC units over 2000 cfm.... May not require a fire alarm but the monitoring of the device has to indicate certain conditions.

[F] 606.4 Controls operation.

e HVAC air handler. Upon activation, the smoke detectors shall shut down all operational capabilities of the air distribution system in accordance with the listing and labeling of appliances used in the system. Air distribution systems that are part of a smoke control system shall switch to the smoke control mode upon activation of a detector.

[F] 606.4.1 Supervision.

The duct smoke detectors shall be connected to a fire alarm system where a fire alarm system is required by Section 907.2 of the International Fire Code. The actuation of a duct smoke detector shall activate a visible and audible supervisory signal at a constantly attended location.

Exceptions:

1. The supervisory signal at a constantly attended location is not required where the duct smoke detector activates the building’s alarm-indicating appliances.

2. In occupancies not required to be equipped with a fire alarm system, actuation of a smoke detector shall activate a visible and audible signal in an approved location. Duct smoke detector trouble conditions shall activate a visible or audible signal in an approved location and shall be identified as air duct detector trouble.

base code does not appear to require it.

Not required, but doesn't say not 'permitted'. If owner or DPR wants to add an alarm system it could be done. If done it must meet Code.
