INSTALLATION AND OPERATION
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
Leave your CO alarm plugged in year-round. CO problems can occur any time
during the year and this alarm can only alert you if it is plugged in and receiving
power.
This CO alarm is intended for use in a standard, unswitched 120VAC wall outlet. It is
not intended for use in extension cords, power strips or outlets controlled by a switch
or dimmer. These may not provide continuous power to the unit. When fully powered,
it samples the air continuously. A microchip inside the unit stores each reading and
remembers the levels of CO it has been exposed to over time. The unit goes into
alarm mode when it has been exposed to a "critical" level of CO (measured in parts
per million or "ppm") within a specified time (measured in minutes).
PLUG THE ALARM INTO AN OUTLET
120 VAC, 60 Hz, 100 mA
This CO alarm should receive continuous electrical power. Do not plug this
alarm into an outlet controlled by a dimmer or switch or ground fault circuit
interrupter.
1. Plug the unit into a standard UNSWITCHED 120VAC outlet. The unit should be
located where it can wake you if it alarms at night.
2. Make sure the green power "ON" LED is on continuously when you plug it in. The
horn will "chirp" during power up or when power is restored after an outage.
Test alarm immediately following installation and weekly for proper operation by
pushing the test button. The alarm will then test itself for proper operation and the red
LED indicator will flash on two 4-pulse patterns and the alarm will simultaneously
sound two 4-pulse patterns. The alarm then resumes normal operation. The Display
will show the highest reading in memory and then three dashes (Model CD-9685).
OPERATION, TESTING & MAINTENANCE
OPERATION: The alarm is operating once the power is connected. When CO gas is
sensed at a high level or at a low level for a lengthy period of time, the unit sounds a
loud alarm which continues until the air is cleared, or the alarm is reset.
If the local alarm is self-cleared, i.e. the carbon monoxide level returns to normal, the
green LED flashes off and on until manually reset.
TESTING YOUR ALARM: Test alarm monthly for proper operation by pushing the
test button. Release the button. The green LED will go off and the yellow LED will
come on. The alarm will then test itself for proper operation and the red LED will flash
on two 4-pulse patterns and the alarm will simultaneously sound two 4-pulse patterns.
The alarm then resumes normal operation. The Display will show the highest reading
in memory and then three dashes (Model CD-9685).
STANDBY CONDITION: The green LED is on and blinks off approximately every 20
seconds whenever AC power is turned on. The Display will only indicate CO readings
higher than 30ppm (Model CD-9685).
ALARM CONDITION: The red LED flashes on and the unit emits a loud, pulsating
alarm (4 short beeps, pause/4 short beeps, pause, until reset). The Display will show
the current CO reading (Model CD-9685).
