Advanced Multi-Criteria
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
locations where absolute certainty is required.
Features
• 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
• 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
carbon monoxide (CO) produced by smoldering fires, 3. infrared (IR)
sensing measures ambient light levels and flame signatures, and 4.
thermal detection monitors temperature.
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 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 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.

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
detection.

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.
