Smoke Alarm placement part IV
This weeks post is from NFPA 72 when placing smoke alarms near cooking appliances in dwelling units.
NEW REQUIREMENT FOR 1/1/2019
29.8.3.4 Specific Location Requirements
(5) Effective January 1, 2019 smoke alarms and smoke detectors used in household fire alarm systems installed between 6 ft. and 20 ft. along a horizontal flow path from a stationary or fixed cooking appliance shall be listed for resistance to common nuisance sources from cooking. (2017).
The following is from NFPA 72 appendix “A” 2017
These are four examples that show how to place smoke alarms when encountering cooking appliances within a certain distance. The zone from 6’ to 20’ and what type of smoke alarm needs to be placed in these zones.

Residential Smoke Alarms Part III
This week we will deal with the locations again, this time it’s for when we place smoke alarms near a ceiling fan, and/or a forced air supply registers.(A/C or Heat)
29.8.3.4 Specific Location Requirements
(7) Smoke alarms and smoke detectors shall not be installed within a 914mm (36 in.) horizontal path from the supply registers of a forced air heating or cooling system and shall be installed outside of the direct airflow from those registers.
(8) Smoke alarms and smoke detectors shall not be installed within a 914 mm (36 in.) horizontal path from the tip of the blade of a ceiling-suspended (paddle) fan.
So if you have a 52” fan then you will need to be 62” away from the box in the ceiling for the fan in order to pass the rough inspection.
Till next time work safe be safe

Residential Smoke Alarms Part II
This week we will look at the location for one on each level. Florida Building Code Residential section R314.3 (3).
R314.3 Location. #3
Smoke alarms shall be installed in the following locations:
3.On each additional story of the dwelling, including basements and habitable attics and not including crawl spaces and uninhabitable attics. In dwellings or dwelling units with split levels and without an intervening door between the adjacent levels, a smoke alarm installed on the upper level shall suffice for the adjacent lower level provided that the lower level is less than one full story below the upper level.

Residential Smoke Alarm placement
In the next couple of weeks we will examine the placement of smoke alarms in dwelling units.
NFPA 72 2013 edition
29.5.1.1* Where required by applicable laws, codes, or standards for a specific type of occupancy, approved single-and multiple-station smoke alarms shall be installed as follows:
(1) In all sleeping rooms and guest rooms
(2) Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft) of any door to a sleeping room, the distance measured along a path of travel
FBC 2017 Residential Code
R314.3 Location.
Smoke alarms shall be installed in the following locations:
1. In each sleeping room.
2.Outside each separate sleeping area in the immediate vicinity of the bedrooms.
Although they seem to have the same information the NFPA 72 version goes into further detail as to the location on the outside of each bedroom. 21’ is how close to the bedroom the smoke alarm is required. So you could cover more than one bedroom with a single alarm where you have grouped bedrooms.
The alarm in the picture on the left could cove additional bedrooms if they are within 21’.
Till next time be safe work safe.

Code Change 450.11 (B) Source Marking
Out in the field we do it all the time, we back feed a transformer with 208v and boost it up to 480v to feed a piece of equipment, or to use it to help with voltage drop in a long run, but now the Code has made it a requirement to be done in accordance with the manufacturer’s instructions. Not all transformers have these instructions.

Continuing Education 2018
We have had a lot of inquires for Continuing Education these past few weeks. Attached find our flyer.
Note!
If you are a newly licensed contractor that received your license after August 31,2016 you will only need 7 hours of continuing education.
Those hours are specific and are covered in our SEMINAR 1.
For those of you that received your license after August 31, 2017 you do not need any Continuing Education, but will just have to pay the renewal fees. If you have any questions you can email me and I will let you know what you need to do to renew your license. jleccemail@hotmail.com

Required outlet at a Commercial/Industrial service location 210.64
This is a new requirement in the 2014 Code that has already been amended in the 2017 Code. In the 2014 it requires a 15 or 20 ampere receptacle
to be installed within 50’ of the service area. Then in the 2017 Code they amended it so that a receptacle will not be required if the voltage of the service
is above 120 volts to ground for services in and around Electrically driven or controlled irrigation machines or near natural or artificial bodies of water in
articles 675 and 682 .
2017 NEC 210.64 Exception No. 2: Where the service voltage is greater than 120 volts to ground, a receptacle outlet shall not be required for
services dedicated to equipment covered in Articles 675 and 682.
So in the picture below you would have to add a transformer and panel to feed a 120 volt GFCI protected receptacle unless it is a service for equipment
covered in articles 675, and 682..

680.22(B)(6) Low Voltage Luminaires New requirement
This weeks comments comes from a recent inspection where the inspector asked the contractor to show a listing for the fixture that he was using next to a pool, that would meet the requirements of this new Code Section 680.22(B)(6). His request was to show that the two (2) wire fixture did not need grounding. The fixture was listed as a low voltage luminaire but did not specifically show that it did not need grounding. The fixture had only two wires and nothing in the manufacturers instructions show grounding the fixture. I asked the contractor if the inspector checked out the type of transformer he used and he said he did not.
The second part of this new section was the use of a transformer that met the requirements of section 680.23(A)(3) which means it is list for use as a pool or spa as a power supply to a fixture. (isolated winding type with an ungrounded secondary that has a grounded metal barrier between primary and secondary or an approved system of double insulation between the primary and secondary windings) The transformer would also have to have specific low voltage contact limits as laid out in 680.2 definitions. (15 volts (RMS) for sinusoidal ac, 21.2 volts peak for nonsinusoidal ac, 30 volts for continuous dc, and 12.4 volts peak for dc that is interrupted at a rate of 10 to 200 Hz.)
This is a new change which allows us to install Low Voltage lighting right next to a pool, the fixture not being grounded is a requirement of this section but only one of three requirements of this new section, so you have to pay attention to the total section when installing lights next to a pool or spa. Make sure that you are complying with all the requirements of this section.
