Description
The System Sensor CO1224T and CO1224TR
(round) Carbon Monoxide (CO) Detectors use a highly
accurate and reliable electrochemical sensing cell to
provide early warning of dangerous CO levels.
With RealTest
®
technology, the CO gas sensing cell
used in the CO1224T and CO1224TR CO detectors
can be tested using a CO gas agent, fully meeting
the requirements of NFPA 720: 2009. 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.)
When dangerous amounts of CO are detected, the
CO1224T and CO1224TR detectors alert residents by
sounding and flashing 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 CO1224T and CO1224TR are designed for system
operation. These detectors are fully listed to UL 2075
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 CO1224T and CO1224TR 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 CO1224T and
CO1224TR will operate on most industry security and
fire alarm control panels.
Architectural/Engineering Specifications
Carbon monoxide detector shall be a System Sensor
model number CO1224T or CO1224TR 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
that 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.
