Regards, Dan Marr Two GREAT Reference Texts, One Low Price! To make it a little easier, I decided to use no more than 40-foot spacing for my detectors. Save when you order the combo package. 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. However, smoke detectors can be installed up to 41 feet apart in corridors up to 10 feet wide. h�bbd``b`a�@�� �̫@\9$LD�W+�ز�����>H#E���� �� This text contains 232 pages. That distance will not be more than 0.7 x the detector’s listed spacing of 30 feet or 21 feet.

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. Certificate upon successful completion of the course. This book is a fundamental reference covering Fire Alarm Systems concepts. 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. 361 0 obj <>stream The detailed explanations and outlines are perfect for those preparing for the NICET Inspection & Testing of Water-Based Systems exam. Using the second spacing method allowed by NFPA 72, these smoke detectors can be spaced nearly 41 feet center-to-center, requiring only 3 smoke detectors to be used. (NFPA 72 2002 ed.) When it comes to heat detector layout, there are some scenarios that are complicated and some that are less complicated. Fire Alarm Systems – Advanced Reference Text. Eleven GREAT Reference Texts, One Low Price! 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. *Fire Tech Productions recommends their online NICET prep courses for the best preparation possible. For areas/corridors 10 feet wide, smoke detectors can be spaced at 41 feet.
