INSTALLATION AND OPERATION
Test/Silence Button
To test the horn and LED indicators hold in the test/silence button until the alarm
indicator comes on. Release the button and the unit will cycle through the alarm pattern
two times. If the unit is in alarm or fault, press the test/silence button to silence the horn.
If the unit is still in alarm or fault after 60 seconds the unit will re-enter alarm mode.
The left power indicator light shining solid green indicates normal operation. Refer to the
chart below for status indicators and explanations.
SYSTEM Green LED Red LED AUDIBLE
STATUS INDICATOR INDICATOR HORN________________
Normal: On Off OFF
Danger: On Flashing 4 BEEPS/5 SEC SILENCE
Fault: Off Flashing INT. BEEP (30 SEC.)
Low Power: Flashing Off INT. BEEP (30 SEC.)
Remote Alarm: Off Flashing 4 BEEPS/5 SEC SILENCE
Silenced: Off Rapid Flashing OFF
TESTING: The audible alarm cannot be checked by the internal circuitry and therefore
the CO Sentinel should be tested frequently using the test button and verifying proper
alarm sequences and operation.
Maintenance:
Unit should be cleaned weekly without the use of solvents.
Cleaning solvents and oils can cause the alarm to stop functioning. Test the alarm if it
has come in contact with any cleaning solvents or any condition that may cause the
alarm to stop working.
After pro-longed storage the CO Sentinel may require up to 72 hours of continuous
operation to reach optimal sensing.
Take Action When the CO Sentinel Alarms
ALARM: When the CO Sentinel enters the danger alarm, the warning (!) indicator is
flashing red and the horn beeps 4 times and pauses for 4-5 seconds in a repeat pattern.
This indicates that the 10% COHb level has been reached.
!WARNING!: Actuation of your CO alarm indicates the presence of carbon monoxide
(CO), which can KILL YOU. If alarm sounds:
Take Action When the CO Sentinel Alarms
a. Operate reset/silence button;
b. Call your emergency services (fire department or 911).
c. Immediately move to fresh air – outdoors or by an open door/window. Do a
head count to check that all persons are accounted for. Do not re-enter the
premises or move away from the open door/window until emergency services
responders have arrived, the premises have been aired out and your alarm
remains in its normal condition.
