For example, if our space has two detectors, the space in the middle of the two detectors will be covered by both detectors. NFPA 72, 17.6.3.1.2 does what it can to make heat detector layout in irregularly shaped areas less complicated. 432 0 obj <>stream There has been confusion in design and code enforcement on what to do when smoke detectors are installed on higher ceilings. We will discuss different ceiling configurations in later posts. The sixteen chapter Water-Based Systems Layout Advanced General Plans Reference text is an invaluable reference for Water-Based Systems Layout professionals. This means that every spot on the ceiling must have at least one detector within 21 feet. Our detector is within 15 feet from all four walls and there are no partitions in this area. The eight chapter Water-Based Systems Layout Advanced Hydraulics Reference text is an invaluable reference for Water-Based Systems Layout professionals. 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. Certificate upon successful completion of the course. Detailed contents can be found in the description for the individual text.

These circles represent the area covered by a spot type smoke detector based on a nominal spacing of 30 feet. All points on the ceiling shall have a detector within a distance equal to or less than 0.7 times the nominal 30 foot spacing. Live in the area?

The 18 chapter Special Hazards Basic Reference text is an invaluable reference for Special Hazards professionals. As you can see, there is no real difference other than a longer dimension in width. 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. (Print, 432 pp., 2022) Section 13.7 . Ceiling height. NFPA 72 2007 section 5.7.3.2.3.5 states that for smooth ceilings, all points of the ceiling shall have a detector within 0.7 times the selected spacing. A thorough understanding of NICET and the certification process. We will have to place a detector no more than 15 feet from the far-right wall and see what we have. The Fire Alarm Systems Advanced Reference Text covers: Fire Alarm Systems Basic, Intermediate & Advanced Reference Texts. 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. Loaded with NFPA references, these texts will become a valuable asset both in the field and office. Spacing ranges between 20 feet to 50 feet.

Regardless of the detectors listed spacing, the process of properly spacing remains the same. Live in the area? As stated in Annex A of NFPA 72-2019, "Where duct detectors are used to initiate the operation of smoke dampers, they should be located so that the detector is between the last inlet or outlet upstream of the damper and the first inlet or outlet downstream of the damper." Filters affect the performance of duct smoke detectors. What about a non-square or non-rectangular space?

Save when you order the combo package. A thorough understanding of NICET and the certification process. Smoke Detector Spacing with a Smooth Ceiling What about the white areas not covered? 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. You may be thinking30 feet and 41.2 feet are NOT the same and the spacing wont work out so what gives?!? We already have two of the measurements just from looking at our layout. The numerous NFPA 70 2014, NFPA 72 2016 and IBC 2015 references, charts and graphs make the text easy to read and follow.
