*Temp 4 pattern is repeated pattern of four short indications
followed by a five second pause.

When the unit has been in alarm for 30 minutes the alarm signal
will be given once every minute.

If ambient conditions return to normal, the unit will self-restore
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
audible 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
alarm will sound a trouble signal every 30-60 seconds and the
trouble contact will open . The alarm must then be replaced.

End of Life Timer feature: When the alarm has reached the end of
its life, the trouble signal will sound every 30-60 seconds and the
trouble contact will open. This indicates that the CO sensor inside
the alarm has passed the end of its life and must be replaced.
This alarm’s lifespan is approximately ten years from the date of
manufacture. Refer to Alarm Replacement on page 3.

Refer to Figure 4 for wiring of the alarm and trouble relays.

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.

3. Screw the base of the alarm 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 alarms have been installed, apply power to the alarm
control unit.

7. Test each alarm as described in Testing.

8. Notify the proper authorities that the system is in operation.

CAUTION

Airborne dust particles can enter the alarm. System Sensor
recommends the removal of alarms before beginning construction
or any other dust producing activity.

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

/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.
