Systemsensor CO1224T Carbon monoxide detector with realtest technology Datasheet

CO1224T
Carbon Monoxide
Detector
with RealTest™ Technology
The System Sensor CO1224T CO detector provides early
warning by using electrochemical sensing technology
to measure carbon monoxide levels in the air.
Features
• RealTest™ technology allows installer to test detector with CO gas
• Full compliance with UL 2075
• A code required trouble relay
• Wiring supervision with SEMS terminals
• A six year end-of-life timer
With RealTest™ technology, the CO gas sensing cell of the
CO1224T CO detector can be tested using a carbon monoxide gas
agent. Simply hold the test button for two seconds. After the alarm
cycle (temp 4) the green LED will flash about once per second,
indicating that the detector is ready to accept CO for testing.
Spray a small amount of CO into the detector per the installation
instructions, and within seconds the detector will alarm, indicating
successful gas entry.
• 12/24 VDC
• A current draw of 20mA in standby and 40mA in alarm
• Versatile mounting for wall and ceiling
• Electrochemical sensing technology
If dangerous amounts of carbon monoxide is detected, the CO1224T
detector will alert residents by sounding and flashing a temp-4 signal
alarm. Protection is guaranteed 24/7 by a central station, regardless
of whether residents are away from home, sleeping or already
suffering from the effects of CO.
This specific device is designed for system operation. The detector is
fully listed to UL 2075. It offers a code required trouble relay to send
a sensor failure or end-of-life signal to the control panel and the
central station. It also uses SEMS-type terminal Philips head screws
to provide a quicker and more positive wiring connection and code
required wiring supervision. The CO1224T detector offers a low
current draw, allowing more devices to be connected to the panel
without having to purchase a more expensive panel or an extra
power supply.

The CO1224T model will operate on most industry security and fire
alarm control panels because it is is a 12/24 VDC detector.
CO1224T Carbon Monoxide Detector Specifications
Architectural/Engineering Specifications
Carbon monoxide detector shall be a System Sensor model number CO1224T, listed to Underwriters Laboratories UL 2075 for Gas and Vapor Detectors and
Sensors. 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 means of SEMS screws. The detector shall provide dual color LED indication, which
blinks to indicate normal standby, alarm, or end-of-life. When 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.

RealTest™ Feature:
T he System Sensor CO1224T carbon monoxide detector with RealTest™ can evaluate the functionality of the CO sensing cell using
canned test agent.
1.
2.
Push and hold the Test/Hush button for
two seconds to enter RealTest mode. The
green LED will flash once every second to
indicate RealTest mode has started.
3.
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.
NOTE: Check with local codes and the AHJ to determine whether or not a functional gas test is desired for an installation.
Hush Feature:
Trouble Feature:
End-of-life Timer:
ushing the Test/Hush button will silence the sounder for 5 minutes (except in RealTest mode).
P
When the detector is in a trouble condition, it will send a trouble signal to the panel.
After the detector’s internal sensor has reached the end of its life, a trouble signal will be sent to the panel. This will indicate that it is
time to replace the detector. An electrochemical carbon monoxide detector lifespan is approximately six years, and the detector must
be replaced by the date marked on the inside of the product.
