Many victims of carbon monoxide poisoning indicate that while they were aware
that they were ill , they became so disoriented and confused that they were
unable to help themselves by either exiting the building or calling for a
assistance. Young children and household pets may be the first affected.
Exposure during sleep is particularly dangerous, because the victim usually
does not awaken.
Actions to take when CO alarm sounding
Ϧ
Μ
WARNING!!
Actuation of your CO alarm indicates the presence
of carbon monoxide (CO) which can kill you. If alarm sounds:
1. Operate test/reset button
2. Call your emergency services(___ _______) or fire department
or 911
3. Immediately move to fresh air –outdoors or by an open door
or window.
Do a head count to check that all persons are
accounted for. Do not reenter the premises nor move away from
the open door/window until the emergency services responders
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 appliance technician
( ) 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’ instruction, 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.
In case of harmful levels of CO gas being detected, your CO alarm
WS4913 will go into a CO alarm mode as mentioned above. In “CO Alarm
Mode” 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 your fire department right away or 911. 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. Turn off fuel burning appliances and call a
qualified technician or your utility company to inspect and repair
your problem before restarting appliances.
Normally an activation of the CO alarm indicates the presence of CO gas.
However, the CO gas can be extremely fatal, if it is not detected. The
source of the CO gas may come from several possible situations, please
refer to the list of sources of carbon monoxide on page 2.
Ϧ
Μ
CAUTION:
This CO alarm 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.
Actions to take after the problem is corrected
Once the source of CO gas in the premises has been eliminated, the
alarm of the CO alarm unit should be off. After waiting for 10 minutes,
push the Test button to test the CO alarm unit so that you can make sure
that it is working properly again.
Test and silence your CO alarm
Follow the test procedure described here or contact your CO alarm
dealer or installer for testing instructions . DSC recommends that
you test the entire alarm system at least one a week to verify the
operation of all functions.
The test/reset button is used to test if the CO alarm is working properly
and to mute the unit during alarm.
Test the unit
Press the test button and you should hear 4 short beeps with a
corresponding 3 LED flashes, in 5 seconds this cycle will repeat one more
time. No alarm signal will be generated at the panel.
Familiarize yourself and your family members with this alarm
pattern as this testing simulates an actual CO alarm condition
.
Silence the unit
While the CO alarm is sounding, pressing the test/reset button will silence
the alarm however the red LED will continue to flash. After 4 minutes, if
the CO concentration that caused the alarm still remains at dangerous
levels, the audible CO alarm will reactivate.
Owners Maintenance
The WS4913 CO alarm is designed to require minimum maintenance,
however, we recommend the following to ensure your CO alarm
continues to function properly:
(a) Use a vacuum cleaner to clean the CO alarm cover once a month,
using the soft brush attachment, never use water, cleaners as they
may damage the unit.
(b) Press the Test/reset button to test its operating function once every
week
Alarm indications

(three) LEDs blink and the built in sounder
beeps for 0.5 second as soon as the battery is installed.
Stand-by mode
:
The green LED flashes once every 60 seconds, which
means the unit is receiving power and also indicates it is functioning
properly.
CO Alarm mode
:
When the unit senses the concentration of carbon
monoxide (CO) in the air around the device exceeds the 'alarm' threshold ,
the red LED light flashes rapidly and built in sounder activates loudly
repeating a sequence of 4 quick beeps followed by a 5 second pause.
L
ow battery warning mode
:
Every 1 (one) minute the yellow LED

2
,
3
or
