6. INSTALLING THE DETECTOR HEAD
(1) Align up the position of head to the base, see Figure
4.
(2) Screw the detector head into the base in clockwise
direction.
7.LED STATUS INDICATION
There are 3 types of detector signaling:
(1) At the end of the start-up time (15 minutes), check
that the GREEN LED flashes every 5 seconds. If
the LED fails to flash, it indicates the detector is not
operating. Check the wiring for the correct voltage.
Replace the detector if necessary
(2) When the carbon monoxide is detected, the LED
will change to a flashing RED, and will be
accompanied by an alarm sound.
(3) When the internal fault is detected, a single short
audible signal will be indicated every 30 seconds.
8. ACTIONS TO TAKE WHEN THE ALARM
SOUNDING
In case of harmful levels of CO gas being detected,
your detector will go into a continuous full alarm. Try
to take the following necessary actions immediately:
(a) If there is anyone experiencing the effects of
carbon monoxide poisoning such as headache,
dizziness, nausea or other flu-like symptoms,
call the emergency services immediately. You
should evacuate all the people in the premises
immediately. Do a head count to check that
everybody is accounted for.
(b) Do not re-enter the premises until the problem
has been corrected and the CO gas has been
dispersed out and a safe level is reached.
(c) If no symptoms exist, immediately ventilate the
home by opening windows and doors.
WARNING: Normally an activation of the detector
indicates the presence of CO gas.
CAUTION: This detector will only indicate the
presence of CO gas at the sensor. However, you
have to be aware that the CO gas may be present in
other areas in the premises.
9. ACTIONS TO TAKE AFTER THE PROBLEM
BEING CORRECTED
When the amount of the CO gas presence in the
premises has been corrected, the alarm from the
detector should silence and the unit should reset
automatically.
10. MAINTENANCE AND TESTING OF CARBON
MONOXIDE DETECTORS
A CO detector constantly monitors for any carbon
monoxide under its normal operational conditions.
The following maintenance procedures for gas
detectors will assure its desired performance:
(1) Use a vacuum cleaner to clean the dust around
the vent holes of gas detector cover.
(2) Carry out a regular or weekly test of gas
detectors. This test should only be carried out if the
LED flashes every 5 seconds.
(a) To test the detector, place a magnet as
indicated in figure 5 on the front of the detector. The
detector should sound and the LED will be a
constant RED.
(b) Remove the magnet; the sounder should stop
sounding and the LED will revert back to flashing
GREEN every 5 seconds.

12. WARNING AND LIMIATION
Note that CQR-983 series gas detector is not
supposed to be used as smoke detector of fire alarm.
In addition, a gas detector will operate normally
under regular power supply; therefore, it will not
detect when power is removed. The detector should
be replaced every 5 years.
WARRANTY INFORMATION
Under the normal operational conditions, the
manufacturer provides a 2 year warranty for the
sensor head of the gas detector and a one-year
warranty for other parts for repairing without charge.
Part and labour charge will be required after the
warranty is expired.
