2 LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook
Introduction
The detector is a highly sophisticated “next generation” high sensitivity aspirating
smoke detection product that provides all the benefits of air sampling high
sensitivity smoke detection, including very early warning. Designed for easy
installation and commissioning, the detector incorporates a patented “artificial
intelligence” known as ClassiFire, which allows the detector to configure itself to
optimum sensitivity, alarm thresholds, and minimum nuisance alarms for various
environments.
The detector operates by drawing air from a protected space via a supervised
piping network in relatively small areas. The sampled air is passed through a
dust separator (filter) to remove dust and dirt before entering the laser detection
chamber. State-of-the-art electronics are used to analyse the sampled air and
generate a signal representing the level of smoke present.
ClassiFire intelligence also monitors the detector chamber and dust separator
for contamination, continually adjusting the appropriate operating parameters to
counteract the negative effects of any contamination. Aspirating smoke detectors
are unique in being able to provide a consistent level of protection in a very wide
range of environments by continuously making minor adjustments to sensitivity.
The aspirating line of detectors detects “difficult-to-detect” slow growth electrical
overload incipient fires in “difficult” environments.
Available software for the detector
The Remote Control and the SenseNET software packages are available for use
with the detector:
• Remote Control software: Provided free of charge with every detector, this
software package enables the user to set up and configure the programmable
functions of one or more detectors or Command Module from a computer
connected via an RS-232 serial cable.
• SenseNET software: SenseNET software is used to configure and manage a
large network of detectors with a simple, streamlined graphical user interface
from a computer connected to a detector or Command Module via an RS-232
serial cable to RS-485 converter interface.
