Advanced Multi-Criteria Detector
with four unique sensing elements

General

This latest addition to Notifier’s Advanced Detection line
combines four complementary technologies into one device to
convey accurate fire sensing information for locations where
absolute certainty is required.

It is designed for use with Notifier’s ONYX series fire alarm
control panels (FACPs).

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. Electrochemical cell technology that monitors carbon
monoxide (CO) produced by smoldering fires

2. Infrared (IR) sensing that measures ambient light levels
and flame signatures

3. Photo-electric smoke detection

4. Thermal detection for temperature monitoring

The integration of continual monitoring for all four major
elements of a fire has enabled Notifier to create a detector that
responds more quickly to an actual fire with the highest
immunity to nuisances. This advanced multi-criteria detector
operates at a high immunity level, changing to become very
sensitive to identify those that should be ignored, reducing
false alarms.

Its on-board 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 cell has an expected lifetime of approximately six
years. It 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.
Detection is not compromised when the CO cell expires. The
algorithms automatically adjust to properly weight the inputs
from the photo-electric, heat, and IR sensors.

Intelligent / Addressable Devices

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.

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
uses thermistor technology with a software-corrected linear
temperature response to offer exceptional nuisance alarm
immunity and excellent fire detection.
