HAA77 GB
3
The green LED should light up when the device is switched on. Your HAA77
requires a ten-minute warm-up, during which the red LED will flash.
The buzzer will sound for at least 4 minutes and the red LED will flash if a CO-
concentration of 100ppm or more is detected for more than 7 minutes running.
CAUTION : Apart from CO, this unit does NOT detect any other type of gas and
does not sense, smoke, heat or flames.
IMPORTANT : This unit may not be activated at low CO levels and has not been
investigated for CO detection below 100ppm. Individuals with a medical condition
may consider using detection devices that are geared to react to lower levels of
COHb.
ACTIVATION OF THE ALARM
Activation of the detector indicates the presence of potentially LETHAL carbon
monoxide levels.
When the buzzer is activated :
a) Check if anyone exhibits symptoms of CO-poisoning such as a severe headache or
an upset stomach. If so, call the fire department and move to a location with lots of
fresh air. MAKE SURE THAT EVERYONE IS ACCOUNTED FOR. DO NOT
RE-ENTER THE BUILDING UNTIL IT HAS BEEN AIRED OUT !
If no one exhibits symptoms of discomfort associated with carbon monoxide
poisoning, you should :
b) Push the reset button.
c) Immediately turn off all appliances or other sources of combustion (furnace, water
heater, wood burning stove, etc.).
d) Ventilate the building.
e) Contact a qualified technician and have the problem fixed before restarting the
appliances.
The CO Detector will stop buzzing after 4 minutes if the CO concentration is
reduced to less than 100ppm, otherwise it will not be deactivated.
NOTE : This detector will only indicate the presence of CO gas in close vicinity to
the sensor. CO gas may be present in other areas.
