The other part is getting the AHJ to approve it. But remember, installing to the code is only part of the magic. In the remainder of this story we’ll discuss code-compliant device placement in an effort to illustrate the most common practices used in the fire alarm industry. The code not only describes where to install these devices, but also how high and how close to known building features they need to be. In order to have reliable, dependable fire alarm operation-whether the building occupants are in California or Florida-standardization using NFPA 72, 101 and 70 is a must. Only then is work legally allowed to start. The bottom line is, before the job can commence, the plans examiner must approve the submittal package that the EC or subcontractor provides. This package usually consists of one or more blueprints that show the position of every device, in addition to product specification sheets, voltage drop and current calculations and other information. This is why fire alarm technicians must turn in a submittal package to the local building department for examination and approval. One question that arises among apprentices and entry-level journeymen is, “How high off the floor and how close to the door do I install these devices?” Knowing the correct answer can mean the difference between a green or red sticker on final inspection.Īlthough installing to Code is important, the authority having jurisdiction (AHJ) must also be on board with whatever the EC does.

Knowing how to install initiation and notification appliance devices is integral to the fire safety mission, and electrical contractors (ECs) who routinely work in this low-voltage segment know all about this. This trade depends on National Electrical Code compliance, especially where it involves device placement and connectivity.
