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.
