2251-COPTIR - System Sensor

Advanced MultiCriteria Fire Detector
with four unique sensing elements
This latest addition to the System Sensor 200 Series
combines four complementary technologies into one
device to convey accurate fire sensing information for
carbon monoxide (CO) produced by smoldering fires, 3. infrared (IR)
sensing measures ambient light levels and flame signatures, and 4.
thermal detection monitors temperature.
locations where absolute certainty is required.
• Unique ability to detect all four major elements of a fire
• Highest nuisance alarm immunity
• Advanced algorithms interpret and respond to the multiple inputs
• Six levels of sensitivity
• CO sensing for fastest response to slow-developing, smoldering fires
• Fully integrated infrared sensing to support the fire alarm decision
• Automatic drift compensation of smoke sensor and CO cell
• Superior EMI protection
• Twin LED indicators providing 360˚ visibility
• LEDs can be panel controlled to blink, latch on, latch off
The detector’s onboard intelligence runs advanced algorithms that
dynamically adjust detection parameters to respond to the inputs
from the sensors, enabling instant response as ambient conditions
change. The program changes sensor thresholds, sensor gain, time,
delays, combinations, sampling rates and averaging rates. If any
sensor fails, the detector automatically adjusts the sensitivity of the
remaining sensors. It also recognizes a fault condition.
The IR light sensor recognizes specific situations, such as welding,
and makes adjustments rapidly to further reduce the potential for
nuisance alarms. The thermal detection function fuses thermistor
technology with a software-corrected, linear temperature response
to offer exceptional nuisance alarm immunity and excellent fire

The integration of continual monitoring for all four major elements of
a fire has enabled System Sensor to create a detector that responds
more quickly to an actual fire with the highest immunity to nuisances.
This advanced multi-criteria detector normally operates at a high
immunity level and changes to become very sensitive to fires as
soon as fire characteristics are sensed. In this way, nuisances are
monitored and ignored, reducing false alarms.
The CO sensing cell has an expected lifetime of approximately
six years. The CO cell is not a field-replaceable component. An
internal timer signals the control panel to indicate the approach of
the CO cell’s end of life. Upon expiration, you should contact the
system supplier to arrange for replacement of the unit. However,
detection is not compromised when the CO cell is expired. The
algorithms automatically adjust to properly weight the inputs from the
photoelectric, heat and IR sensors.
• Built-in test switch
This plug-in fire detector combines four separate sensing elements
in one unit: 1. photoelectric chamber senses airborne particulate
for smoke detection, 2. electrochemical cell technology monitors
NOTE: The CO cell is specifically deployed as a component of smoke
detection in this device. This device is not listed for applications in
which standalone CO detection is required for life safety.
