How To Install This Heat Alarm - Firex ADH Owner's Manual

• Install heat alarms on peaked, cathedral, or gabled ceilings 1 meter (3 feet)
f rom the highest point (measured horizontally).
• In a room with open joists or beams, all ceiling mounted heat alarms shall
be located on the bottom of joists or beams – not in joist channels.
• Heat alarms installed on an open-joisted
ceiling shall have their smooth ceiling
spacing reduced to no more than half of
the listed spacing when measured at right
angles to solid joist.
DO NOT install heat alarms:
• In areas with high humidity, like bathrooms or areas near dishwashers or
washing machines. Install at least 10 feet (3 meters) away from these are a s ,
if possible.
• Near air returns, heating and cooling supply vents, fans, decorative
objects, window molding etc. that may prevent heat from entering the
unit thus interrupting its alarm.
• In rooms where temperatures may fall below 23°C (-10°F) or rise above
38°C (100°F).
• Near fluorescent lights - electrical noise and flickering may affect the

Mobile home installation
For mobile homes built after 1978, install heat alarms as directed above. For
mobile homes built before 1978, install heat alarms on an inside wall between 10
and 30 cm (4 and 21 inches) from the ceiling. (Older mobile homes have little or
no insulation in the ceiling which may affect the heat alarm 's ability to detect
heat pro p e r l y.) This is especially important if the ceiling is unusually hot or cold.
