[]{#__RefHeading___Toc185831523 .anchor}1.06 SYSTEM DESCRIPTION

The air sampling system, referred to as a high sensitivity smoke
detection (HSSD) system, provides early warning of a fire in its
incipient stage. HSSD systems are typically installed in semiconductor
facilities, under raised floors containing combustible materials,
computer facilities, locations with high air-flow environments requiring
smoke detection, and other locations where conventional spot-type smoke
detectors are not appropriate for the application.

The standard AnaLASER II detector has a dynamic sensitivity range of
0.00075% to 0.3%/ft. that utilizes laser particle-counting technology.
Smoke concentration is determined by counting the number of discrete
particles of a specific size in a given time period. The detector's
particle size discrimination features allows only a specific range of
particle sizes (between 0.01 and 10 microns) to be measured and counted
as products of combustion. Anything above or below this range is
generally ignored and does not contribute to smoke signal calculations.
This discrimination band corresponds to the center of the range of all
particles of combustion. Dust particles, which are typically larger than
10 microns, are ignored.

The air sampling pipe network is a system of pipes extended into the
protected area with strategically placed sampling holes. The Fenwal
"SNIFF" computer program is used to dynamically balance the pipe network
to insure equal sensitivity at each sampling hole. Each sample hole can
be considered an equivalent spot-type detector with a maximum coverage
of 900 ft^2^. The protected area monitored by each AnaLASER II detector
can not exceed 20,000 ft^2^.

Each AnaLASER II detector is equipped with six relays (Pre-Alarm 1,
Pre-Alarm 2, Alarm 1, Alarm 2, Trouble, and Isolate). The Alarm 2 and
Trouble relay outputs are monitored by the building fire alarm system
for evacuation of the facility upon an alarm event and to provide
notification when the AnaLASER II detector has a trouble event. The
alarm relay outputs are typically configured to be non-latching with a 0
-- 60 seconds delay used to eliminate unwanted alarms caused by
transient conditions.

The detector has an optional Display Module provided for each AnaLASER
II detector to provide user interface for visual indication of the
detector's alarm and trouble status on a LCD screen. The Display Module
provides the ability to 1) reset the detector after latching alarms or
troubles have been cleared, 2) disable alarm outputs to allow the
detector to be tested without generating alarms, 3) perform detector
sensitivity tests, and 4) to silence the internal sounder.

Supervised 24 VDC power with 24-hour backup is provided to up to four
AnaLASER II detectors by a Multi-Zone Power Supply. For locations where
the AnaLASER II detector is utilized with a FM-200 release panel, the
detector may utilize the backup power capability of the release panel.
