Lastly, you'll not find anything in NFPA 72 2007 edition, which requires spacing reduction for releasing applications. The Annex of NFPA 72 provides us with a diagram to assist in smoke detector spacing. It is appropriately titled “Irregular Areas” and states “. In those cases, we go on to the next requirement in the fire alarm code, 17.6.3.1.2. This book is a fundamental reference covering Inspection & Testing of Fire Alarm Systems concepts. The sixteen chapter Water-Based Systems Layout Advanced General Plans Reference text is an invaluable reference for Water-Based Systems Layout professionals. On a sloping ceiling, beams run up the slope and are 14" deep. Then layout your detectors. It becomes clearer when you get it all on a scaled drawing and measure out the distance from the upper left corner to the closest detector. The horizontal spacing for a detector in a room with five minutes per air change is ? Coupling this text with our Fire Alarm Systems Level II Online Course is a perfect study package for those preparing for the NICET Fire Alarm Systems Level II exam. When we previously discussed fire alarm detector layout, we went through a series of square rooms/spaces to demonstrate how to place spot type fire alarm detectors, as shown in the example below. from nominal pressure. From your illustration, I presume this is a singular beam, not a repeated pattern. What if the space the detector needs to be placed in is an irregular shape? Like most of the NFPA codes, NFPA 72: National Fire Alarm and Signaling Code is updated every 3 years.

White Paper Clarifies NFPA 72 Smoke-Detector Spacing on Level Ceilings with Beams and/or Joists October 24, 2006 St. Charles, IL-based System Sensor, a Honeywell company, now offers a white paper that addresses concerns about correct spacing of smoke detectors on … This fourteen chapter Fire Alarm Systems – Intermediate Reference text is an invaluable reference for Fire Alarm Systems Technicians and Professionals. This reduction is dependent on the rate at which air is circulated in the space. The second measurement, which we will designate as “b” is 20 feet from the detector’s center point to the far-left wall. The building and life safety codes tell you where smoke detectors are required; NFPA 72 tells you how to install and test them. You are correct that NFPA 72 doesn't directly address your situation. down from the ceiling to the top of the detector. Well, there’s a little geometry magic going on.

If you have ceilings that are pitched, install the alarm within 3 feet of the peak but not within the apex of the peak (four inches down from the peak). Obviously the installation of a single smoke detector in a protected space, with logic requiring 2 detectors to initiate a release goes against the release logic. Course content continually reviewed and updated. Coupling this text with our Fire Alarm Systems Level I Online Course is a perfect study package for those preparing for the NICET Fire Alarm Systems Level I exam. Two GREAT Reference Texts, One Low Price! Look at the detector curve illustrated, we see that there are different dimensions on the curve that start with the standard spacing of 30-foot by 30-foot and works its way down to the 42.4 dimension for very narrow spaces. However, even if I would have gone with 41.2 feet as my spacing per the detector curve, it would have still worked out close to what I laid out above: 4 detectors and no spot on the ceiling more than 21 feet away from the closest detector. and 12 in.) They have a recommended spacing of 30 feet between detectors. However, as NFPA 72 was completing this last cycle, several such incidents occurred, which spurred some initiatives at the state and local level to reduce or relax the requirements for fire alarm systems in schools. h�bbd``b`a�@�� �̫@\9$LD�W+�ز�����>H#E���� �� This text contains 339 pages.

Using the Second Method. What about a non-square or non-rectangular space? %PDF-1.6 %���� Heat detector spacing for irregularly shaped areas spacing can exceed listing provided the maximum spacing from detector to farthest point of sidewall or corner within its zone does not exceed .7 (70%) of its listed spacing, 5.6.5.2. Using those two measurements we can use the theorem to solve for “c” (our measurement from the corner of the space to our heat detector) to see if we have violated NFPA 72 detector spacing rules. Detailed review of NFPA 12 and 70 2011, NFPA 72 2013 and NFPA 2001 2012 (per level of study). Loaded with NFPA references, these texts will become a valuable asset both in the field and office.
