OPERATION, TESTING & MAINTENANCE
OPERATION:
The heat alarm is operating once the power is connected and turned
on (the battery must also be installed). When air temperature above 135
o
F is sensed,
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.
STANDBY CONDITION:
The red LED flashes once every 40-60 seconds to indicate
the unit is properly functioning.
LOCAL ALARM CONDITION:
The red LED flashes rapidly and the unit emits a loud,
pulsating alarm sound.
REMOTE ALARM CONDITION:
The red LED is off and the unit emits a loud, pulsating
alarm.
GREEN LED:
The green LED is on whenever AC power is turned on.
TESTING:
Test by pushing the test button on the heat alarm cover until the alarm
sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are
working. If no alarm sounds, the unit may have a defective battery or other failure.
NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit's operation as required by Underwriters Laboratories Inc. (UL).
BACKUP BATTERY REPLACEMENT
Disconnect AC power before changing battery. Shock hazard exists if AC power
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).
Push and lift the battery door latch and remove the battery from the battery door.
While observing polarity, push the replacement battery into the battery door until it is
held securely in place. Carefully close and latch the battery door.
REPAIRS AND SERVICES
If the heat alarm is defective in any way, do not tamper with the unit. Return the unit
for servicing. (See warranty for instructions or in-warranty returns.) There will be a
service charge for repairing out of warranty units.
