Construction Elements

Beams

Concrete beams, such as these in the photo, can either be cast on the construction site, or brought in, manufactured elsewhere. Typically, the detectors that will be used in a fire alarm system are going to be located at the roof of the building. When one looks at the construction of a building, there are a number of different ways that the roof is supported. The members on the horizontal plane at the ceiling or under a mezzanine are beams. Whether they are called purlins, girders or beams is not an issue to the fire alarm application. The dimension of the unit is the critical factor in determining the effect the support member has on the spacing of detectors.

For purposes of the fire alarm code, a beam is a solid structural or non-structural element that extends down from the roof at least four inches, and is spaced more than three feet, center to center. Thus, a beam can be anything from a plastic, artificial wood beam that is glued to the ceiling of a room for architectural effect, to a large I-beam at the roof of an industrial building that is a crane rail.
