Installation
Sloped Ceilings
The following information is from the National Fire Protection Association and is listed in Fire Code 72. Install Smoke Alarms on sloped, peaked or cathedral ceilings at, or within 3’ (0.9m) of the highest point (measured horizontally). Smoke alarms in rooms with ceiling slopes greater than 1’ to 8’ (0.3m - 2.4 m) horizontally should be located on the high side of the room. Do not place the alarm in the peak of an “A” frame type ceiling (see Diagram B)
Mobile Homes
Modern mobile homes have been designed and built to be energy efficient. Install Smoke/CO alarms as recommended above. (Refer to Recommended Installation Instructions and Diagram A).
In older mobile homes that are not well insulated, extreme heat or cold can be transferred from the outside to the inside through poorly insulated walls and roof. This may cause a thermal barrier, which can prevent smoke from reaching an alarm mounted on the ceiling. In such mobile homes install your Smoke/CO Alarm on an inside wall with the top edge of the alarm at a minimum of 4” (10cm) and a maximum of
12” (30.5cm) below the ceiling. (See Diagram A). If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and ceiling are either hot or cold, install your alarm on an inside wall only!
Installation
Locations To Avoid
WARNING: Do not install in garages, kitchens, furnace rooms or bathrooms! Install at least 5’ (1.5 m) away from any fuel burning appliance.
Do not install within 3’ (.9m) of the following:
The door to a kitchen, or a bathroom that contains a tub or shower, forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. Avoid excessively dusty, dirty or greasy areas. Dust, grease or household chemicals can contaminate the alarm’s sensors, causing it to not operate properly.
Place the alarm where drapes or other objects will not block the sensors. Smoke and CO must be able to reach the sensors to accurately detect these conditions. Do not install in peaks of vaulted ceilings, “A” frame ceilings or gabled roofs. Keep out of damp and humid areas. Do not place near a diaper pail.
Smoke alarms are not to be used with detector guards unless the combination (alarm and guard) has been evaluated and found suitable for that purpose.
