FUNCTIONAL GAS TEST
NOTE: Check with local codes and the AHJ to determine whether or not a
functional gas test is necessary for an installation.
Solo C6 brand canned CO testing agent may be used to verify the detec-
tor’s ability to sense CO by utilizing the RealTest® feature of the CO1224T/
CO1224TR as follows:
1. Press the test button as described in Testing above.
2. Once the alarm has entered the speed-up test mode, indicated by a
quickly flashing green LED, spray a small mount of CO agent within 1/4"
of the alarm’s gas entry ports (see Figure 3). The unit will go into alarm
if gas entry is successful.
3. The detector will automatically exit the speed-up test mode 20-60 sec-
onds after entering speed-up test mode.
Testing the detector will activate the alarm relay and send a signal to the panel.
CAUTION: This carbon monoxide detector is designed for indoor use only. Do
not expose to rain or moisture. Do not knock or drop the detector. Do not open
or tamper with the detector as this could cause malfunction. The detector
will not protect against the risk of carbon monoxide poisoning if not properly
wired. The detector will only indicate the presence of carbon monoxide gas at
the sensor. Carbon monoxide gas may be present in other areas.
This carbon monoxide detector is NOT:
• Designed to detect smoke, fire or any gas other than carbon monoxide
• To be seen as a substitute for the proper servicing of fuel-burning appli-
ances or the sweeping of chimneys.
• To be used on an intermittent basis, or as a portable alarm for the spill-
age of combustion products from fuel-burning appliances or chimneys.
• To be used in airplanes or any other aeronautical vehicle.
Carbon monoxide gas is a highly poisonous gas which is released when fuels
are burnt. It is invisible, has no smell and is therefore impossible to detect with
the human senses. Under normal conditions in a room where fuel burning
appliances are well maintained and correctly ventilated, the amount of carbon
monoxide released into the room by appliances should not be dangerous.
Symptoms of carbon monoxide poisoning: Carbon monoxide bonds to the
hemoglobin in the blood and reduces the amount of oxygen being circulated
in the body. The following symptoms are examples taken from NFPA 720.
They represent approximate values for healthy adults:
Concentration (ppm CO) Symptoms
200 Mild headache after 2-3 hours
of exposure
400 Headache and nausea after
1-2 hours of exposure
800 headache, nausea, and dizziness
after 45 minutes of exposure;
collapse and unconsciousness
after 2 hours of exposure
Many causes of reported carbon monoxide poisoning indicate that while vic-
tims are aware that they are not well, they become so disoriented that they
are unable to save themselves by either exiting the building or calling for as-
sistance. Young children and pets may be the first to be affected.
Per UL standard 2075, the CO1224T/CO1224TR has been tested to the sensi-
tivity limits defined in UL standard 2034.
Alarm thresholds are as follows:
Parts Per Million Detector response time, min.
30 ±3ppm No alarm within 30 days
70 ±5ppm 60-240
150 ±5ppm 10-50
400 ±10ppm 4-15
What to do if the carbon monoxide detector goes into alarm:
Immediately move to a spot where fresh air is available, preferably outdoors.
Find a phone in an area where the air is safe and call your security service
provider. Tell your provider the detector alarm status, and that you require
professional assistance in ridding your home of the carbon monoxide.
IMPORTANT: This detector should be tested and maintained regularly follow-
ing National Fire Protection Association (NFPA) 720 requirements.
MAINTENANCE
Occasionally clean the outside casing with a cloth. Ensure that the holes on
the front of the alarm are not blocked with dirt and dust.
Do not paint, and do not use cleaning agents, bleach, or polish on the detector.
DETECTOR REPLACEMENT
This detector is manufactured with a long-life carbon monoxide sensor. Over
time the sensor will lose sensitivity, and will need to be replaced with a new
System Sensor carbon monoxide detector. This detector’s lifespan is approxi-
mately ten years from the date of manufacture.
Periodically check the detector’s replacement date. Remove the detector cover
and refer to the sticker placed on the inside of the detector. The sticker will
indicate the date that the detector shall be replaced.
This detector is also equipped with a feature that will open the trouble relay
once it has reached the end of its useful life. If this occurs, it is time to replace
the detector.
NOTE: Before replacing the detector, notify the proper authorities that main-
tenance is being performed and the system will be temporarily out of service.
Disable the zone or system undergoing maintenance to prevent any unwanted
alarms. Dispose of detector in accordance with any local regulations.
