The idea is the same, but what if the space the detector needs to be placed in is an irregular shape? Following the spacing rules of NFPA 72, Chapter 17, specifically Section 17.6.3.1.1, we know our detector layout must follow one of the two requirements below. System layout is an important aspect of fire alarm work, yet remains one of the subjects that is viewed as difficult, at least according to some of the folks I have spoken with. Water-Based Systems Layout Hydraulics Reference Text, Inspection & Testing of Water-Based Systems Basic & Intermediate Reference Texts.

Intermediate Reference Text. }Q-~@\]m6n7LXp_u|1|wL&> ;]. hn8W) (8vhDnSb:EipngAHADxa p$fA8 IP A,pA# The Inspection & Testing of Water-Based Systems Basic Reference Text covers: Inspection & Testing of Water-Based Systems NFPA 72, The National Fire Alarm Code, recommends using 900 square feet (30 feet on center) as a guideline for spacing spot type smoke detectors on smooth ceilings. Fire Protection Research Foundation report: Smoke Detector Spacing for High Ceiling Spaces November 2017 It states: "Detectors shall be mounted at the bottom of the joists." In our case it works out since the joists we placed the detectors on are spaced at 3-foot intervals with the first joist being 1.5 feet from the wall. Start out with easy rooms. Detailed descriptions can be found in the Learn More link for each individual text. In most scenarios, there will be no need to use the Pythagorean Theorem. January 2019 These circles represent the area covered by a spot type smoke detector based on a nominal spacing of 30 feet. Spacing ranges between 20 feet to 50 feet. Smoke Detector Spacing with a Smooth Ceiling What about the white areas not covered? Reference Texts, Water-Based Systems Layout General Plans Reference Text. February 2022 June 2021 Save when you order the Complete Water-Based Reference Library. In case you are unfamiliar with the theorem, it is c. Using the theorem, I can figure out the distance from the upper left corner of our tunnel to the center point of the closest detector. Effective tips, hints and test strategies to help lead you to exam day success. NFPA 72, cir. According to 17.6.3.1.2, we are code complaint because that distance is less than the heat detector's listed 30-foot spacing x 0.7 (21 feet). Detailed review of NFPA 72 2016, NFPA 92 2018 and OSHA 29 CFR 1926 (per level of study). As you get the hang of it, start experimenting with moving the detectors closer to the walls to see how that might affect your detector layout. June 2020 Using the theorem, we find that the farthest spot on the ceiling is approximately 20.61 feet away from the closest heat detector in our very narrow tunnel. The average ceiling height is 15 feet. Well also say that this tunnel requires heat detectors in it because of local building codes. Youll just need to do some quick multiplication to get the information you need and then you can place your heat detectors where you need them.

April 2018 For areas/corridors 10 feet wide, smoke detectors can be spaced at 41 feet. This section of the standard allows you to use smooth ceiling spacing and the smoke detectors can be mounted on the ceiling, bottom of the beams or on the sidewall. September 2022 90 days (single level purchase) / 120 days (multiple level purchase) self-paced study online access. and Drew Martin [1] There is a body of research, including standard fire tests, non-standard fire tests, Next, we will look at a larger space to see how detector spacing works out.
