Normal Operation

When no carbon monoxide is present, the red light will flash approximately
once every 60 seconds.

Test / Reset Button (in Normal operation)
If required, the alarm operation can be checked for correct operation
by pushing the Test/Reset button on the front of the unit.

Alarm Conditions
When the unit detects carbon monoxide the alarm signal is sounded
continuously. The red alarm light will flash and the alarm will sound
approximately 4 times every 5 seconds.

When the unit has been in alarm for a period of approximately 4 minutes,
the alarm signal will be given every 60 seconds.

Test / Reset Button (in Alarm condition)
If required, the audible alarm signal can be silenced for a period of 6 minutes by
pushing the Test/Reset button on the front of the unit. The red light will continue
to flash.

If the carbon monoxide is still present after the 6 minute period, the audible
alarm will resume the previous alarm condition. The Test/Reset button should
not be used repeatedly and the actions “What to do when the alarm sounds”
should be followed.

Return to Normal Operation
When the carbon monoxide gas disperses, the alarm will stop. The red light will
flash approximately once every 60 seconds (normal operation). The user should
check for the source of CO any time the alarm has sounded, even if the alarm
has returned to its normal working conditions.

Battery Replacement / Fault Warning
When the batteries need replacing the unit will sound 1 short beep once every
60 seconds. The batteries must then be replaced. The red light will flash once as
normal. If the detector continues to sound 1 short beep every 60 seconds it must
be replaced.

Room spaces should be well ventilated when household cleaning supplies
are used as these may cause a false alarm.

The alarm is designed to be wall mounted using the hardware provided.
Find a position to install the alarm (see “Where to put the alarm” and
“Where not to put the alarm”).

Option 1
Special Mounting Pad with Nail (supplied)
Place the nail through the mounting pad.
Using a hammer, gently knock the nail into
the wall ensuring that the mounting pad is
not hammered too firmly into the wall.

Option 2
Screw and Insert (NOT supplied)
If the wall is too hard to use the nail,
use a No. 4 round head screw and insert.

Press the test/reset button on the front of the alarm, hold for several
seconds and check that the red light flashes and the audible alarm sounds.
The detector can be hung on the protruding nail using the ‘keyhole’ on
the back.

Activation of your CO alarm’s audible buzzer

indicates the presence of carbon monoxide (CO)

which can KILL YOU.

1. Operate reset/silence button.

2. Call your emergency service

(Phone: _______________________________) [fire department or 911].

3. 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 nor move away from the open door/window until
the emergency services have arrived, the premises have been aired out
and your alarm remains in its normal condition.

4. After following steps 1-3, if your alarm reactivates within a 24-hour

period, repeat steps 1-3 and call a qualified technician
(Phone: _______________________________) to investigate for sources
of CO from fuel burning equipment and appliances and inspect for proper
operation of this equipment. If problems are identified during this
inspection have the equipment serviced immediately. Note any
combustion equipment not inspected by the technician and consult the
manufacturers’ instructions, or contact the manufacturers directly, for
more information about CO safety and this equipment. Make sure that
motor vehicles are not and have not been operating in an attached
garage or adjacent to the residence.

Please add the telephone number of your emergency services and a qualified
technician to the labels provided and place one copy next to the appliance and
the other near a source of fresh air where you plan to gather in the event of
an alarm.

Pull down catch to open detector and pull ribbon to remove batteries.

Carefully remove old batteries from battery housing and dispose
of old batteries with care.

Using only batteries listed in 'Care and Maintenance of Alarm' insert 3 new
batteries, ensuring they snap securely into place and cannot be shaken
loose. When inserting the batteries, ensure the polarity is correct - ie:
positive end of battery (+) aligns with the (+) symbol in the battery housing.
Press the test/reset button and check that the red light flashes and the
buzzer sounds. The detector is now operating and ready for use.


Dispose of the alarm in accordance with local regulations.
