Locations for Smoke Alarms

Post by vedard » Sat Sep 17, 2016 9:18 am

1. Recommended Locations for Photoelectric Alarms
  • Locate the first alarm in the immediate area of the bedrooms but not in the bedrooms. Try to protect the exit path as the bedrooms are usually farthest from the exit. If more than one sleeping area exists, locate additional alarms adjacent to each sleeping area.
  • Locate additional alarms in the bedrooms if required.
  • Locate additional alarms to protect any stairway as stairways act like chimneys for smoke and heat.
  • Locate at least one alarm on every floor level.
  • Locate an alarm in every room where electrical appliances are operated (i.e. portable heaters or humidifiers).
  • Locate an alarm in every room where someone sleeps with the door closed. The closed door may prevent the alarm from talking the sleeper.
  • Smoke, heat and combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling in the center of the room. Place it closest to all points in the room. Ceiling mounting is preferred in ordinary residential construction.
  • When mounting an alarm on the ceiling, locate it at a minimum of 4" (10cm) from the side wall.
  • When mounting the alarm on the wall, it is best to use an inside wall with the top edge of the alarm at a minimum of 4" (10cm) and a miximum of 12" (30.5cm) below the ceiling.
  • Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more than 30 feet (9.1m) long.
  • Install smoke alarms on sloped, peaked or cathedral ceilings at or within 3 fet (0.9m) of the highest point (measured horizontally).
2.Locations to avoid for smoke alarms
Alarms must not be located within 3 feet of the following:
  • Supply and return registers used for forced air heating and air conditioning.
  • Ceiling fans and other high air flow areas.
  • Bathrooms which contain a tub or shower.
In general, alarms should not be located:
  • In the garage. Products of combustion are present when you start your automoble.
  • In an area where the temperature may fall below 40F or rise above 100F
  • In dusty areas. Dust particles may cause nuisance alarms or failure to alarm.
  • In a kitchen or cooking area where steam and smoke from burning food or toast can cause nuisance alarms.
  • Near fluorescent lights. Electronic "noise" may cause nuisance alarms.

Most fatal fires happen to occur at night during sleep. A good an efficient smoke alarm would detect and alert you. NEC (National Electric Code ) does not require smoke detectors though most local codes do.
The NFPA (National Fire Prevention Association) suggests ceiling near doorway or stairway as the ideal place for smoke detectors because the smoke rises and seeks the easiest route of escape. Home fire protection systems in Toronto suggest hallway ceiling also should have one installed. The kitchen is one top priority location inside or outside. Beware, smoke from cooking, disconnection, battery failure would cause nuisance alarms
Get a smoke alarm installed inside each bedroom, outside your sleeping area. Have one installed in your basement? Ensure that it is installed on every level of your home. If there is no bedroom in any level, go for the living room, stairway or in both locations.
CO Detectors would ensure maximum protection for every floor and sleeping area. They have to be mounted five feet from the ground to get the best reading of your home’s air.
