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

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)

device to convey accurate ﬁre sensing information for sensing measures ambient light levels and ﬂame signatures, and 4.

thermal detection monitors temperature.

locations where absolute certainty is required.

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

Features

nuisances. This advanced multi-criteria detector normally operates at

•ꢀUnique ability to detect all four major elements of a fire

a high immunity level and changes to become very sensitive to ﬁres

•ꢀHighest nuisance alarm immunity

as soon as ﬁre characteristics are sensed. In this way, nuisances are

monitored and ignored, reducing false alarms.

•ꢀAdvanced algorithms interpret and respond to the multiple inputs

•ꢀSix levels of sensitivity

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.

•ꢀ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

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.
