CO1224A Carbon Monoxide Alarm

CO1224A
Carbon Monoxide
Alarm
System Sensor’s CO1224A provides early warning
when its electrochemical sensing technology
accurately measures carbon monoxide levels in the air.
Carbon monoxide is an odorless, colorless, tasteless and highly
toxic gas that is produced when fuels, such as wood, gasoline,
charcoal and oil, are burned with insufficient air. The majority of
residential and commercial fatalities caused from these fuels come
from heating systems, power tools and charcoal grills.
If carbon monoxide is detected, the CO1224A will alert residents by
sounding and flashing a temp-4 signal alarm. Additional protection is
provided with built-in alarm and trouble contacts which can be used
for monitoring. This can provide protection regardless of whether
residents are away from home, sleeping or already suffering from the
effects of CO. The alarm contact has a 10 second delay so the unit
can be tested with the test pushbutton without activating the alarm
contact.
Features
•Full compliance with CSA 6.19-01
•Alarm/Trouble contacts
•Wiring supervision with SEMS terminals
•A six-year end-of-life indication
•12/24 VDC
•A current draw of 20mA in standby and 40mA in alarm
•Versatile mounting for wall and ceiling
•Electrochemical sensing technology
The CO1224A trouble relay can send a sensor failure or end-oflife signal to the control panel and the central station. SEMS-type
terminal Philips-head screws provide a quicker and more positive
wiring connection and code required wiring supervision. Also,
the CO1224A offers a low current draw, allowing more detectors
to be connected to the panel without having to purchase a more
expensive panel or an extra power supply.
Because the CO1224A is a 12/24 VDC detector, it will operate on
most industry security or fire alarm control panels.

Specifications
Architectural/Engineering Specifications
Carbon monoxide alarm shall be a System Sensor model number CO1224A, listed to ULC in compliance with CSA 6.19-01. The detector shall be equipped with
an alarm/trouble sounder, alarm/trouble relay, and test/silence pushbutton. The alarm relay shall have a 10 second delay. 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 LED indicators, which blink to indicate normal standby, alarm, or trouble/end-of-life conditions. When the sensor supervision is in a trouble
condition, the detector shall sound an audible trouble signal and activate the trouble relay. When the detector gives a trouble or end-of-life signal, the detector
shall be replaced.

CO1224A
Hush Feature:
ushing the Test/Hush button will silence the
P
sounder for 5 minutes.
Trouble Feature:When the detector is in a trouble condition,
it will sound a trouble signal and activate the
trouble relay.
End-of-life Timer: After the sensor inside the detector has reached
the end of its useful life, a trouble signal will
sound and the trouble contact will activate.
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.
