ASD-LS
ANALOG ADDRESSABLE LASER
SMOKE SENSOR
DESCRIPTION
The FCI Model ASD-LS low profile laser smoke sensor
adds another new dimension to analog addressable fire de-
tection. It incorporates laser smoke detection technology that
provides unsurpassed sensitivity and response to maximize
detection. This 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 com-
bine with an array of integral software tools to make the
quickest possible decision in the event of a genuine fire. The
sensor can swiftly sense smoldering fires, but yet can sense
the smallest particles of combustion, providing a faster re-
sponse to flaming fires.
The early warning capability of the ASD-LS is comparable
to that of aspiration technology, while unlike aspirating sys-
tems, 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, temperature,
transient smoke, humidity, etc.). Patented algorithms distin-
guish between particles of dust and smoke. The focused
beam of the laser light source minimizes reflection from ac-
cumulated dust in the optical chamber, effectively minimiz-
ing problems caused by dust build-up. The software
performs its own independent analyses of the sensor signal.
These analyses include dust spike rejection, drift compensa-
tion, 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 sensors for any appreciable sig-
nal to determine if the spike is caused by a fast flaming fire.
The sensor is of plug-in construction and is directly inter-
changeable in the same base with the FCI ASD/ATD/Accli-
mate Series low-profile sensors. A wide variety of bases,
with sounder, relay, etc. is available. Remote LED annuncia-
tor 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 oper-
ation for sensors located electrically between the bases.
