LOW BATTERY CONDITION: When the battery voltage drops, the alarm will sound
one short beep per minute and the green LED will flash. Replace the battery
immediately in order to provide uninterrupted protection. Please see SECTION 5 for
information regarding battery replacement.
ALARM CONDITION: When CO gas is detected at a level and duration specified in
SECTION 2, the alarm will sound and the red LED will flash. The alarm signal will
sound 4 short beeps every 6 seconds for 4 minutes, and thereafter 4 short beeps every
minute.
MEMORY RETRIEVAL OF CO GAS DETECTED (FOR MODELS 7035/SL): To
retrieve from memory the CO gas detected, press TEST / RESET button for a minimum
of five seconds. The LCD will display the recorded data in the following order:
1. The current CO level detected in ppm,
2. The peak or highest CO level detected in ppm,
3. The total length of time the alarm has detected the peak CO level in minutes, and
4. The percentage of carboxyhemoglobin.
Each reading will appear for two seconds. To erase the record in memory, press TEST /
RESET
button for twelve seconds and until the alarm bursts a long beep and the display
shows "000". Disconnecting the battery from the alarm will also erase the memory.
TESTING: To test your alarm, press the TEST / RESET button on the cover and hold it
down for a minimum of 5 seconds. This will simulate a CO concentration of
approximately 400 ppm CO gas and sound the alarm if all the electronic circuitry, and
buzzer are working.
The alarm will not sound when the button is pressed if the unit is already in the “trouble”
condition.
LCD DISPLAY FUNCTION (FOR MODELS 7035/SL): In normal operation, the LCD
display is blank. When the alarm is activated, the LCD display will indicate the current
CO level detected in ppm.
DO NOT TRY TO TEST THIS ALARM IN ANY OTHER WAY.
If no alarm sounds during a test, check the battery power. If the alarm still does
not sound, the unit may be defective and should be returned for service (SEE SECTION
11).
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 (SEE SECTION 11).
MAXIMUM "PPM" READING AND OVERFLOW (FOR MODELS 7035/SL): The LCD
will display CO concentrations up to 500ppm. Above 500 ppm, the LCD will display a
flashing "500".
RESET: The CO alarm will automatically reset itself when the CO gas which caused
the alarm has cleared. However, the alarm will activate for at least 4 minutes if it is not
manually reset. You can silence the alarm by pressing the
TEST / RESET button. If a
CO concentration of 70 ppm or greater continues to be detected, the alarm will activate
again within 4 minutes. See SECTION 2...
WARNING...If alarm signal sounds:... and follow instructions 1), 2), 3), 4).
