This weeks post deals with battery operated smoke alarms and when you can use them.

Florida building ‘code allows us to use battery operated smoke alarms under certain conditions, the following text is from FBC Resdientila section R314.

2017 FLORIDA BUILDING CODE RESIDENTIAL

SECTION R314 SMOKE ALARMS¨

One-family and two-family dwellings and townhomes undergoing a repair, or a Level 1 alteration as defined in the Florida Building Code, may use smoke alarms powered by 10-year nonremovable, nonreplaceable batteries in lieu of retrofitting such dwelling with smoke alarms powered by the dwelling’s electrical system. A battery-powered smoke alarm that is newly installed or replaces an existing battery-powered smoke alarm as a result of a Level 1 alteration must be powered by a nonremovable, nonreplaceable battery that powers the alarm for at least 10 years. The battery requirements of this section do not apply to a fire alarm, smoke detector, smoke alarm, or ancillary component that is electronically connected as a part of a centrally monitored or supervised alarm system, that uses a low power, radio frequency wireless communication signal; or that contains multiple sensors, such as a smoke alarm combined with a carbon monoxide alarm or other multisensor devices, and is approved and listed by a nationally recognized testing laboratory

Repairs, as defined in Chapter 2, include the patching or restoration or replacement of damaged materials, elements, equipment or fixtures for the purpose of maintaining such components in good or sound condition with respect to existing loads or performance requirements.

Level 1 alterations include the removal and replacement or the covering of existing materials, elements, equipment, or fixtures using new materials, elements, equipment, or fixtures that serve the same purpose.

These just recently showed up in the stores.  They are 10 year non-replaceable battery types that do interconnect wirelessly.

The interconnection was always a problem because in NFPA 72 it calls for these to be inter-connected but where not available until recently. They have Carbon monoxide alarms also available with the 10 year battery and it is also interconnectable.

But as stated above they are only allowed in a Level 1 alteration or a repair as defined by FBC.

So if your inspector was requiring the interconnection we now have them available to us.  The above package was around $80 for the two-pack., and the carbon monoxide one was $80 each.  They can be connected to you phone through another option that costs around $100.  So technology if finally catching up to our needs in the field.

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.

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’.

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.
