®
Technology
The System Sensor CO1224T, CO1224TR, and CO1224A
(Canada) Carbon Monoxide (CO) Detectors use a highly
accurate and reliable electrochemical sensing cell to
provide early warning of dangerous CO levels.
Features
• A 10-year end-of-life timer
• RealTest® enables a functional test using canned CO
• A code-required trouble relay
• Wiring supervision with SEMS terminals
• 12/24 VDC
• A low current draw of 20 mA in standby and 40 mA in alarm
• Versatile mounting for wall and ceiling
• Accurate and reliable electrochemical sensing technology
•
Optional CO-PLATE CO Detector Replacement Plate to upgrade
previously installed competitor detectors to the CO1224T or
CO1224A.
• CO1224T tested up to 12,000 feet above sea level
When dangerous amounts of CO are detected,
the CO1224
Series CO detectors alert residents by sounding and fl ashing a temp
4 signal alarm. With 24/7 central station monitoring, residents are
guaranteed protection whether they are away from home, sleeping,
or already suffering from the effects of CO.
The CO1224 Series detectors are designed for system operation.
These detectors are fully listed to UL 2075 (US models only) and
CSA 6.19-01 (Canada model only) and offer a code-required trouble
relay to send a sensor failure or end-of-life signal to the control
panel and the central station. The CO1224 Series detectors also
use SEMS-type terminal Philips head screws for quicker and more
positive wiring connections and code-required wiring supervision.
With a low current draw, these detectors enable more devices to be
connected to the panel, limiting the need to purchase extra power
supplies or more expensive panels. As 12/24 VDC detectors, the
CO1224 Series detectors will operate on most industry security and
fi re alarm control panels.
With RealTest
®
technology, the CO gas sensing cell used in the
CO1224 Series CO detectors can be tested using a CO gas agent,
fully meeting the requirements of NFPA 720: 2009 (US models only).
Simply put the detector into RealTest mode, spray a small amount
of CO into the detector per the installation instructions, and within
seconds the detector will alarm, indicating successful gas entry. (See
the reverse page or the user manual for complete instructions.)

CO1224 Series Detectors Carbon Monoxide Detector Specifications
Architectural/Engineering Specifi
cations
Carbon monoxide (CO) detector shall be a system-connected System Sensor model number CO1224T or CO1224TR listed to Underwriters

Laboratories UL 2075 for Gas and Vapor Detectors and Sensors. The Canadian model CO1224A, is ULC listed to CSA 6.19-01, for res
idential
carbon monoxide alarm devices. The detector shall be equipped with a sounder and a trouble relay. The detector’s base shall be
able to
mount to a single-gang electrical box or direct (surface) mount to the wall or ceiling. Wiring connections shall be made by mea
ns of SEMS
screws. The detector shall provide dual-color LED indication that blinks to indicate normal standby, alarm, or end-of-life. Whe
n the sensor
supervision is in a trouble condition, the detector shall send a trouble signal to the panel. When the detector gives a trouble
or end-of-life
signal, the detector shall be replaced. The detector shall provide a means to test CO gas entry into the CO sensing cell.
The detector shall
provide this with a test mode that accepts CO gas from a test agent and alarms immediately upon sensing CO entry. For the CO122
4T only,
the detector shall perform in the detection of CO up to 12,000 feet above sea level and alarm within the time specifi ed by ANSI
/UL 2034
for CO concentrations of 70, 150 and 400 parts per million (ppm), as verifi ed by a Nationally Recognized Test Laboratory.

Feature:

The System Sensor CO1224 Series CO Detectors enable evaluation of

the functionality of the CO sensing cell using a canned CO test agent.
Hush Feature:

Pushing the Test/Hush button will silence the sounder for 5 minutes (except in RealTest mode).
Trouble Feature:

When the detector is in a trouble condition, it will send a trouble signal to the panel.
End-of-Life Timer:

After the detector’s internal sensor has reached the end of its life, a trouble signal will be sent to the panel
to indicate it is time to replace the detector. An electrochemical CO detector lifespan is about ten years.
The detector must be replaced by the date marked on the inside of the product.
CO-PLATE:
System Sensor also offers the CO-PLATE CO Detector Replacement Plate to cover the footprint (when necessary)
of previously installed competitive carbon monoxide detectors that require replacement.

Push and hold the Test/Hush button for
two seconds to enter RealTest mode. The
green LED will fl
ash once every second to
indicate RealTest mode has started.
Spray canned CO agent into the
detector.
Verify CO sensing at the control panel.
The detector will automatically exit
RealTest alarm mode after about 20-60
seconds.
