the unit sounds a loud alarm which continues until the air is cleared.
This alarm incorporates the internationally recognized horn signal for evacuation. During
alarm mode, the horn produces three short beeps followed by a two second pause
and then repeats. This pattern is somewhat different than the previous alarm sound,
which continually beeped.

is miswired.
The heat alarm uses a 9 Volt battery. The battery should last for at least one year
under normal operating conditions. The heat alarm has a low battery indicator, an
audible "beep." It will operate at 30-40 second intervals for a minimum of 7 days.
When this indication occurs, replace the battery with an Alkaline type (Eveready
Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak #1604P, Eveready
#216), or Lithium type (ULTRALIFE U9VL-J).
