Installation Guidelines
In a wall location, the alarm should be at least as high as a
light switch, and at least six inches from the ceiling. In a ceiling
location, the alarm 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 alarm should be placed just outside the room
so the alarm can be heard more easily
Where NOT to install, ideally:
• Alarms 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 alarm’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 CO1224A can be wall- or ceiling-mounted:
1. To a single gang box, or
2. Direct mount to wall or to ceiling using drywall fasteners.
in place. Do not put wires more than 2 gauge apart under the
same clamping plate.
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 locatsed 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 alarm. Once the snap is
loosened, lift the bottom end of the cover up and unhinge the
top to remove the cover.
2. Wire the alarm base screw terminals per Figure 4.

Wiring Installation Guidelines
All wiring must be installed in compliance with the Canadian
Electrical Code, applicable local codes, and any special
requirements of the local Authority Having Jurisdiction (AHJ).
Proper wire gauges should be used. The conductors used to
connect carbon monoxide alarms 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
of insulation from the end of the feed wire, inserting it into the
proper base terminal, and tightening the screw to secure the wire
1
/4˝
Carbon monoxide alarms are not to be used with detector guards
unless the combination has been evaluated and found suitable for
that purpose.
Testing
Alarm 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 alarm to stabilize before testing.
Test the CO1224A alarm 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 for
1-4 seconds.
3. If the sounder beeps twice in the Temporal 4 pattern and the
LEDs light up, the detector is operational.
4. The detector now enters Realtest speed up test mode indicated
by a quickly blinking green LED. See Functional Gas Test
section for instructions on testing with canned CO.
Note: The alarm contact has a time delay of approximately
10 second before operation. To test for the alarm contact
operation, the test button must be held down for at least 10
seconds.

If an alarm fails the above test method, its wiring should be
checked. If the alarm still fails after rewiring, it should be replaced.
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
alarm’s ability to sense CO by utilizing the functional speed-up
test feature of the CO1224A 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 alarm will automatically exit the speed-up test mode 20
seconds after entering speed-up test mode.
Testing the alarm will activate the alarm relay and send a signal
to the panel.
CAUTION: This carbon monoxide alarm is designed for indoor use
only. Do not expose to rain or moisture. Do not knock or drop the
alarm. Do not open or tamper with the alarm as this could cause
malfunction. The alarm will not protect against the risk of carbon
monoxide poisoning if not properly wired. The alarm will only
indicate the presence of carbon monoxide gas at the sensor. Carbon
monoxide gas may be present in other areas.
This carbon monoxide alarm 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 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
appliances 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 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
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).
3 I56-3247-006
10-28
S0298-01E
• Medium exposure: Sever throbbing headache, drowsiness,
confusion, fast heart rate.
• Extreme exposure: Unconsciousness, convulsions, cardio
respiratory failure, death.
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 diz-
ziness after 45 minutes of
exposure;
collapse and unconsciousness
after 2 hours of exposure
Many causes of reported carbon monoxide poisoning indicate
that while victims 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 assistance. Also young children
and pets may be the first to be affected.
Per CSA 6.19-01 the CO1224A has been tested to the following
sensitivity limits.
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 alarm 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 alarm status,
and that you require professional assistance in ridding your home
of the carbon monoxide.
IMPORTANT: This alarm 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 alarm.
Alarm Replacement
This alarm 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 alarm.
This alarm’s lifespan is approximately ten years from the date of
manufacture.
Periodically check the alarm’s replacement date. Remove the alarm
cover and refer to the sticker placed on the inside of the alarm. The
sticker will indicate the date that the alarm should be replaced.
This alarm is also equipped with a feature that will sound a trouble
signal every 30-60 seconds and open the trouble relay once it has
reached the end of its useful life. If this occurs, it is time to replace
the alarm.
NOTE: Before replacing the alarm, 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. Dispose of alarm in accordance
with any local regulations.
