FireBrand CQR-983 Series User manual

1. INTRODUCTION
CQR’s Carbon Monoxide Detector is effective for
detecting a build-up of carbon monoxide, also known as
CO gas, in your home or business. It is easy to install
and allows connection to a fire control panel or security
system.
(1) Monitors for carbon monoxide in a continuous
manner.
(2) Gives a loud alarm (85dB) when it detects a
build-up of carbon monoxide.
(3) Self-test its operative functions continuously
(4) Offers a 2 year warranty for the carbon monoxide
sensing unit.
(5) Meets the requirements of EN 50291 for sensitivity.
2. POSSIBLE SYMPTOMS OF CARBON
MONOXIDE POSIONING
Carbon monoxide is colourless, odourless, tasteless, and
very toxic. When inhaled, it produces an effect know as
chemical asphyxiation. Injury is due to the combining of
CO with the available hemoglobin in the blood, lowering
the oxygen-carrying capacity of the blood. In the
presence of CO gas, the body is quickly affected by
oxygen starvation.
The following symptoms are relayed to CO poisoning
and should be discussed with all members of the
household so that you know what to look for:
(a) Extreme exposure: unconsciousness, convulsions,
cardio respiratory failure, death
(b) Medium exposure: severe throbbing headache,
drowsiness, confusion, vomiting, fast heart rate
(c) Mild exposure: slight headache, nausea, fatigue
(similar to “flu-like”symptoms)
Young children and household pets may be the first
affected. Exposure during sleep is particularly dangerous,
because the victim usually does not awaken.
3. LOCATIONS TO INSTALL YOUR DETECTOR
Since CO gas moves freely in
the air, the suggested
location is in or as near as
possible to sleeping areas of
the home. The human body is
most vulnerable to the effects
of CO gas during sleeping
hours. For maximum
protection, a CO detector
should be located outside primary sleeping areas or on
each level of your home. In the adjacent figure are
suggested locations in the home. The electronic sensor
detects carbon monoxide, measures the concentration
and sounds a loud alarm before a potentially harmful
level is reached.
Do not place the detector in the following areas:
(a) where the temperature may drop below 4.4℃or
exceeds 40℃.
(b) Near paint thinner fumes
(c) Within 1.5 meters of open flame appliances such as
furnaces, stoves and fireplaces
(d) In exhaust streams from gas engines, vents, flues
or chimneys
(e) Do not place in close proximity to an automobile
exhaust pipe; this will damage the detector.
4. INSTALLING THE BASE OF DETECTOR
(1) All the wires in the base should be flattened and
should not touch any of the other connectors to
ensure that the detector head is smoothly secured to
the base.
(2) When using the jump wires to check the
connectivity for each gas detector in the circuit loop,
be sure to remove all the jump wires before
attaching the detector head onto the base.

6. CHANGING THE RELAY
The relay is located in the detector head, the default
setting is NC (Normally Closed) to change the relay
output of the unit use the following procedure:
(1) Remove the screws from under the connections
label on the back of the detector head
(2) Remove the front cover to expose the PCB.
(3) Remove the jumper above the relay as indicated in
fig 3.
(4) Place on the required setting NO or NC
(5) Carefully replace the cover.
(6) Refit the screws

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.
