10. MAINTENANCE
10.1: ALARM REMOVAL:
Turn off the AC power supply to the heat alarm at the main distribution board. To replace the battery remove the
alarm from the trim ring by rotating the alarm in the direction of the TURN TO REMOVE arrow on the cover (see
Section 7 fig.4 and Section 10.2 fig 5).
To disconnect the A.C. power harness, squeeze the locking arms on the sides of the quick connector while pulling
the connector away from the bottom of the alarm (see Section 7, fig.3).
10.2: BATTERY INSTALLATION AND REPLACEMENT:
To replace or install the battery you must first remove the alarm from
the trim ring by following the ALARM REMOVAL instructions at the
beginning of this section. After alarm has been removed you can open
the battery door and install or replace the battery. Install the battery to
the battery terminal clip of the heat alarm. When installing the battery,
press the battery lever down into the battery compartment and install the
battery. (see fig.6).
CAUTION ! If the battery compartment is closed without a battery,
the red battery tamper will prevent the heat alarm
from attaching to the trim ring. USE ONLY THE FOL-
LOWING 9Volt BATTERIES FOR HEAT ALARM REPLACEMENT:
Alkaline type: EVEREADY 522, DURACELL MN1604 or MX1604
Lithium type: ULTRALIFE U9VL-J
NOTE: REGULAR WEEKLY TESTING IS RECOMMENDED
WARNING!!! Use only the batteries specified. Use of different batteries may have a detrimental effect on the
alarm. Exposure to temperature extremes and / or high humidity may reduce battery life.
AFTER CLEANING, REINSTALL YOUR ALARM AND TEST YOUR ALARM BY USING THE TEST
BUTTON AND CHECK THAT THE GREEN LED IS ON.
11. CLEANING YOUR ALARM
Before cleaning the heat alarm, turn off the AC power supply to the heat alarm at the main distribution board. To
clean your alarm, remove it from the trim ring and disconnect the A.C. Quick Connect power harness as outlined in
the beginning of this section. You can clean your alarm by using a vacuum cleaner hose and vacuuming around the
heat sensing element and the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth.
We recommend a periodic monthly inspection and cleaning of the Heat Alarm to ensure proper operation.
AFTER CLEANING, REINSTALL YOUR ALARM AND TEST YOUR ALARM BY USING THE TEST
BUTTON AND CHECK THAT THE GREEN LED IS ON.
12. LIMITATIONS OF THE HEAT ALARM
Heat Alarms are not designed to protect life safely against fire and smoke. In most fires, hazardous levels of
toxic gases and smoke can build up before the heat alarm will operate. In cases where life safety is an issue,
Heat Alarms should only be used to provide an added source of protection and as a supplement to the smoke
alarm installation.
HEAT ALARMS DO NOT ALWAYS DETECT FIRES.
The fire may be a slow smouldering (smoke producing) and low heat producing type. The fire maybe in a
different room than the heat alarm, or the heat from the fire may bypass the alarm. This heat alarm will not
detect smoke, gases or flames.
Home fires develop in DIFFERENT ways and are often unpredictable. No one type of alarm (Heat,
Photo-electric or Ionisation) is always best, and a given alarm may not always provide warning of a fire. Also,
alarms do have limitations. Mains powered alarms may not operate if mains power has been cut off such as
by an electrical fire or an open fuse. Alarms must be tested regularly to make sure the batteries and the alarm
circuits are in good operating condition.
Heat Alarms cannot provide an alarm if heat does not reach the alarm. Therefore, heat alarms may not sense
fires starting in chimneys, walls, on roofs, on the other side of a closed door or on a different floor, it may not
wake up a sound sleeper. The use of alcohol or drugs may also impair one’s ability to hear the alarm. For
maximum protection heat alarms should only be used as a supplement to smoke alarms. Smoke alarms
should be installed in each sleeping area, on every level of a home and be interconnected with each other and
the heat alarms.
