7. INSTALLING THE BASE PLATE
After installation TEST your alarm by pressing and holding the test button for several seconds. You can also use a
hand held hair dryer to test your heat alarm.
Complete details on this procedure are outlined in Section 8.
CAUTION ! Early warning fire detection is best achieved by the installation of smoke alarms in all rooms and areas
of the household as follows: A smoke alarm should be installed in each separate sleeping area (in the
vicinity of - but outside the bedroom) and heat or smoke alarm where appropriate in the living rooms,
dining rooms, kitchens, hallways, attics, furnace rooms, closets, utility storage rooms, basements, and
attached garages.
8. OPERATION
The Heat Alarm is operating once A.C. power is applied, new battery is installed and testing is complete. When
the Heat Alarm senses temperatures above 73°C (163.4°F) (plus or minus a few degrees), the horn will sound a loud
(85db) pulsating alarm until the temperature drops below 73°C (163.4°F). The heat alarm is designed to activate at
73°C when the temperature range is between 58°C(136.4°F) and 88°C(190.4°F).
FLASHING RED LED LIGHT: This Heat Alarm is equipped with a flashing Red LED. The LED is located under
the test button and has two functions.
1. Stand-by Condition---The Red LED will flash every 30-40 seconds to indicate that the Heat Alarm is operating
properly.
2. Alarm Condition ----When the unit detects heat and goes into alarm the red LED will flash rapidly ( 2-3
times per second ). The rapid flashing LED and pulsating alarm will continue until the
temperature drops below 73°C (163.4°F).
WHEN HEAT ALARMS ARE INTERCONNECTED with compatible Smoke Alarms, only the Red LED of the
originating unit will flash rapidly. All other units in the interconnect system will sound an alarm but their Red LED’s
will not flash.
TESTING: Test by pushing the test button on the cover and hold it down for a minimum of 5 seconds. This will
sound the alarm if all the electronic circuitry and horn are working correctly.
The test switch may not cause a test signal if the ambient temperature is below 8° C (20°F). In this
case, test the unit by blowing hot air at the alarm sensing element with a hair dryer held about
20cm from the unit.
If no alarm sounds, check the fuse or circuit breaker supplying power to the alarm circuit, if the alarm still does not
sound the unit may have defective battery or other failure.
IT IS RECOMMENDED TO TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION.
Erratic or low sound coming from your alarm may indicate a defective alarm, and it should be returned for service.

9. FALSE ALARMS
To avoid false alarms, DO NOT USE WHERE THE MAXIMUM ROOM TEMPERATURE WILL EXCEED 88°C .
Heat Alarms respond only to heat. They do not detect smoke. If the alarm does sound, check for fires first. If a fire is
discovered, get out of the house and call the Fire Brigade. If no fire is present, check to see if one of the reasons
listed in Section 2 may have caused the alarm.
