Table 1. Detector Operation Modes:

(standby)
Alarm -
*Temp 4 pattern is repeated pattern of four short indications followed by a five second pause.
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 condition (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
WARNING
CAUTION
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:
The screw terminals in the mounting base will accept 14-22 gauge
wire. Wire connections are made by stripping approximately
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
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
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.

Wiring Installation Guidelines
All wiring must be installed in compliance with the NFPA 70, National 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.
Airborne dust particles can enter the detector. System Sensor recommends 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 maintenance 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
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).
