When the detector has been in alarm for 30 minutes the alarm
signal will be given once every minute.
If ambient conditions return to normal, the detector will self-re-
store out of alarm and into Normal (standby) mode.
Hush feature: If required, the audible alarm can be silenced for
5 minutes by pushing the button marked “Test/Hush”. The red
alarm light will continue to flash in temp-4 pattern. If carbon
monoxide is still present after the 5 minute hush period, the au-
dible alarm will sound. The hush facility will not operate at levels
above 350 ppm (parts per million) carbon monoxide.
Trouble feature: When the sensor supervision is in a trouble con-
dition (such as a sensor that has been tampered with), the detec-
tor will send a trouble signal to the panel. The detector must then
be replaced.
End of Life Timer feature: When the detector has reached the
end of its life, the trouble contact will open. This indicates that
the CO sensor inside the detector has passed the end of its life
and must be replaced. This detector’s lifespan is approximately
six years from the date of manufacture. Refer to Detector Replace-
ment on page 3.
Per UL 2075, it is mandatory that a trouble signal be sent to the
panel upon CO cell trouble or cell end of life. Refer to Figure 4
for wiring of the trouble relay.

Installation Guidelines
In a wall location, the detector should be at least as high as a light
switch, and at least six inches from the ceiling. In a ceiling loca-
tion, the detector should be at least 12 inches from any wall.
Where to install, ideally:
• Within 10 feet of all sleeping areas
• Inside the bedroom if it contains a fuel burning appliance
• On every floor of the building
• Ideally, install in any room that contains a fuel burning appliance
• If the appliance in the room is not normally used, such as the
boiler room, the detector should be placed just outside the
room so the alarm can be heard more easily
Where NOT to install, ideally:
• Detectors operate best if not installed within 10 feet of any
cooking appliance
• Directly above a sink, cooker, stove or oven
• Next to a door or window that would be affected by drafts i.e.
extractor fan or air vent
• Outside
• Do not install in any environment that does not comply with
the detector’s environmental specifications
• In or below a cupboard
• Where air flow would be obstructed by curtains or furniture
• Where dirt or dust could collect and block the sensor
• Where it could be knocked, damaged, or inadvertently removed
Mounting
The CO1224 can be wall- or ceiling-mounted:
1. To a single gang box, or
2. Direct mount to wall or to ceiling using drywall fasteners.
Figure 2. Mounting of Detector:
Wiring Installation Guidelines
All wiring must be installed in compliance with the NFPA 70, Na-
tional Electrical Code, applicable state and local codes, and any spe-
cial requirements of the local Authority Having Jurisdiction (AHJ).
Proper wire gauges should be used. The conductors used to con-
nect carbon monoxide detectors to the alarm control panel and
accessory devices should be color-coded to reduce the likelihood
of wiring errors. Improper connections can prevent a system from
responding properly in the event of a CO.
The screw terminals in the mounting base will accept 14-22 gauge
wire. Wire connections are made by stripping approximately 1/4˝
of insulation from the end of the feed wire, inserting it into the
proper base terminal, and tightening the screw to secure the wire
in place. Do not put wires more than 2 gauge apart under the
same clamping plate.
WARNING: This product does not have a local audible trouble
signal, and may fail without supervision if trouble loop remains
unconnected.
WARNING: Gas detectors on a zone that is bypassed may not signal
a trouble condition. Do not bypass zones used for gas detectors.
Wiring diagrams located on page 4, Figure 4.
Installation
WARNING
Remove power from alarm control unit or initiating device circuits
before installing detectors.
1. Using a small, flat head screw driver, push in the small tab
located on the underside of the detector. Once the snap is
loosened, lift the bottom end of the cover up and unhinge the
top to remove the cover.
2. Wire the detector base screw terminals per Figure 4.
3. Screw the base of the detector onto a single gang electrical
box, or to the surface of the wall or ceiling. Use the hardware
included in the packaging.
4. Hinge the top portion of the cover onto the base; with the cover
at a 45 degree angle, fit the hinges into the slots of the base.
5. Push the unhinged bottom portion of the cover down until it
snaps into place.
6. After all detectors have been installed, apply power to the
alarm control unit.
7. Test each detector as described in Testing.
8. Notify the proper authorities that the system is in operation.
CAUTION
Airborne dust particles can enter the detector. System Sensor rec-
ommends the removal of detectors before beginning construction
or any other dust producing activity.
Carbon monoxide detectors are not to be used with detector
guards unless the combination has been evaluated and found
suitable for that purpose.
Testing
Detector must be tested after installation.
NOTE: Before testing, notify the proper authorities that mainte-
nance is being performed and the system will be temporarily out
of service. Disable the zone or system undergoing maintenance to
prevent any unwanted alarms.
Ensure proper wiring and power is applied. After power up, allow
80 seconds for the detector to stabilize before testing.
Test the CO1224 detector as follows:
1. A test button is located on the detector housing (See Figure 3).
2. Use the tip of your finger to press and hold the test button.
3. If the sounder beeps and the LED’s light up after 1-4 seconds,
the detector is operational.

Figure 3. Test Button Location and Operation:
If a detector fails the above test method, its wiring should be checked.
If the detector still fails after rewiring, it should be replaced.
The manufacturer cannot recommend a specific agent with
which to test the detector.
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 car-
bon monoxide
• To be seen as a substitute for the proper servicing of fuel-burn-
ing appliances or the sweeping of chimneys.
• To be used on an intermittent basis, or as a portable alarm for
the spillage of combustion products from fuel-burning appli-
ances or chimneys.
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 condi-
tions 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 related to carbon monoxide poisoning and should be discussed
with all members of the household:
Mild exposure: Slight headache, nausea, vomiting, fatigue
(often described as “flu-like” symptoms).
•
Medium exposure: Sever throbbing headache, drowsiness,
confusion, fast heart rate.
Extreme exposure: Unconsciousness, convulsions, cardio re-
spiratory failure, death.
Many causes of reported carbon monoxide poisoning indicate that
while victims are aware that they are not well, they become so dis-
oriented that they are unable to save themselves by either exiting
the building or calling for assistance.
Also young children and pets may be the first to be affected.
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 following 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 approximately six 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
should 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 maintenance is being performed and the system will be tempo-
rarily out of service. Disable the zone or system undergoing main-
tenance to prevent any unwanted alarms. Dispose of detector in
accordance with any local regulations.
