ASD-LS
Description
The Gamewell-FCI, Model ASD-LS, is a low profile laser
smoke sensor that adds another new dimension to analog
addressable fire detection. It incorporates laser smoke
detection technology that provides unsurpassed sensitivity
and response to maximize detection. This feature makes
the sensor ultra-sensitive to smoke, as much as 100 times
more sensitive than conventional photo-electric smoke
detection technology.
An innovative laser diode and precision optics design
combine with an array of integral software tools to allow
the sensor to quickly identify the fire. The sensor can
swiftly sense smoldering fires, but yet can sense the
smallest particles of combustion, providing a faster
response to flaming fires.
The early warning capability of the ASD-LS is comparable
to that of Aspiration Technology, while unlike Aspirating
Systems, the ASD-LS can pin-point the location of the fire.
The sensor is continually monitored to measure any
change in its sensitivity due to the environment (dirt, tem-
perature, transient smoke, humidity, etc.). Patented algo-
rithms distinguish between particles of dust and smoke.
The focused beam of the laser light source minimizes
reflection from accumulated dust in the optical chamber,
effectively minimizing problems caused by dust build-up.
The software performs its own independent analysis of the
sensor signal. This analysis includes dust spike rejection,
drift compensation, smoothing, multi-sensor, pre-alarm
decision and alarm decision. In the event of spikes in the
signal, the sensor will check the output of adjacent sen-
sors for any appreciable signal to determine if the spike is
caused by a fast flaming fire.
The sensor is a plug-in construction and is directly inter-
changeable in the same base with the Gamewell-FCI,
ASD/ATD/Acclimate Series low-profile sensors. A wide
variety of bases, with sounder, relay, etc. is available. The
Remote LED annunciator capability is also available as an
optional accessory.
The ASD-LS sensor is Listed for use inside ducts up to a
velocity of 4,000 FPM.
An optional isolator base, Model B224BI, is also available.
Installation of two of these isolator bases allows Style 7
operation for sensors located electrically between the
bases.
