EN 54-20 compliance
The installation must be designed using PipeCAD software, which is provided
free on the CD shipped with each detector. After designing the installation
including pipes, endcaps, and sampling holes, enter the detector type. To select
the detector type, select Options, select Calculation options, and then select the
detector from the Type drop-down list.
Select Options > Calculate, or click on the calculator icon. The software will
prompt you to choose from Use set hole sizes, Best flow balance, or Max.
permissible transit time. Select the appropriate option, and then click OK. The
results for each pipe (View > Results) show calculations for each sampling hole
on the pipe with the nearest to the detector at the top of the screen, and the
endcap hole at the bottom.
For EN 54-20 compliance the transport time of the last sampling hole shall be
checked following all installation and proven to be less than or equal to that
determined by PipeCAD.
The classification of each sampling device configuration and associated
sensitivity settings are determined by the column headed Hole sensitivity %
obs/m which shows the predicted sensitivity for each hole. For the installation to
comply with EN 54-20 depending on the class of installation, each sampling hole
must be no less sensitive than the following:
Class A: 0.62% obs/m
Class B: 1.95% obs/m
Class C: 4.65% obs/m
The calculation can be further refined by leaving a working detector in the
protected area for at least 24hrs at the intended alarm factor for the installation
(this could be done before or after installation). The detector sensitivity can be
read from the “Sensitivity” figure on the histogram screen of the Remote software
supplied with each detector. Click Options > Calculation options to open the
Hole calculation options dialog box. Enter the sensitivity value obtained from the
practical test, and then click OK. The new calculated value will use the real
sensitivity from the practical test.
The PipeCAD software will determine the classification of any used configuration.
Commissioning and periodic system tests must involve smoke tests to verify that
the system performs as expected and enters Fire (Alarm) 1 alarm within the time
determined by PipeCAD from the farthest hole. The detector sensitivity must also
be inspected to ensure it has not radically fallen from the installed figure. If it has
changed for any reason, the new figure must be re-entered into PipeCAD and the
recalculated hole sensitivities must be confirmed to be within the class limits
shown above.

vi LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook
The settings of a compliant system should be recorded, as it is possible by
changing certain programmable functions to make the system non-compliant. If
functions are changed, it is recommended that the system is retested if
continuing compliance is in any doubt.
Note: For EN 54-20 compliant installations the detector requires that the flow
thresholds be set manually to ± 6% of the nominal value, after the FastLearn
phase is completed. For example, if the flow rate is 64% after the completion of
the FastLearn period, the user must manually set the low flow threshold to 58%
and the high flow threshold to 70%.

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.

Standard detector
The standard detector may be operated as a stand-alone unit, or may be part of
a network of detectors centrally monitored by a command module. It may be
programmed via its front panel, as in the standard detector and command
module versions, shown in Figure 2 on page 5 and Figure 3 on page 6.
Alternatively, the standard detector can be ordered without a front panel display
(minimum display) as shown in Figure 1 on page 5. The detectors may be
programmed remotely via the detector’s RS-485 terminals using a command
module, or via the detector’s RS-232 port using a PC running the Remote Control
software. A copy of this software is supplied with each detector.
The standard detector without a front panel display is housed in a rugged sheet
metal steel enclosure. This detector includes LEDs to indicate alarms, faults, and
normal operating conditions. The standard detector with display (and command
module) can also be ordered with the steel enclosure.

Stand-alone command module or command
module detector
When multiple detectors are networked together, a command module may be
used to tie all the detectors together and to provide a centralized point for
network access and programming, running diagnostics, and PC and fire panel
connection.
The command module can be mounted either inside a detector or as a stand-
alone unit in its own housing without an aspirator or smoke detection circuitry. If
detectors attached to the Command Module are mounted in different fire zones
then the Command Module must be mounted in its own housing with separate
power supply to comply with BS5839 and EN 54.
When a command module is mounted inside a detector, the Standard detector
display is replaced with a dedicated command module display. The programming
buttons and display on the front of the detector belong to the command module.
Programming at the command module is very similar to programming a detector,
the main difference being that the command module has extra functions to
control all the aspirating detectors connected in the network.

Figure
8 : Command module detector
(1) The <TEST> Button starts a lamp test which makes the detector show its nominal operating
sensitivity as calculated by the ClassiFire Artificial Intelligence System.
(2) The <RESET> Button clears any latched alarms or faults and sets the status display back to
its normal operation display. To comply with national standards, detectors are supplied with
the RESET function disabled as the default.
(3) MENU Buttons are used when programming the unit, which is password-protected. See
“Navigating through the menus” on page 46, for more information. Pressing the UP or
DOWN arrow keys when not in Programming Mode (the access code has not been entered)
scrolls through the detector’s event log. Refer to “Event log” on page 61 for more information
(4) The OK Indicator illuminates to show normal operation when there are no faults. On the
command module, this means that the command module and all detectors on the loop are
operating normally.
(5) The Fault Indicator illuminates when the unit has a fault and a fault signal is being sent to
the fire alarm panel. On the command module, this also indicates a fault in a detector on the
communications loop, or in the loop itself.

Chapter 1: Product and component descriptions
LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook 11
(6) The <ISOL> Button toggles the unit‘s isolation state. When isolated, the unit cannot
generate any alarms and will signal a fault condition and the text display will show Panel
Isolate. A detector is shipped with its <ISOL> Button disabled as default. These three
buttons can be individually enabled or disabled. The factory default state of the detector is:
<TEST> button enabled and <RESET> and <ISOL> buttons disabled.
(7) Status Display (if fitted) shows all events as they happen in real time and is also used to
configure the unit.
(8) Smoke Density Indicators (scaled smoke levels) display absolutely scaled smoke levels
above 1% obscuration per metre (0.30% obscuration per foot) to a maximum of 25% obs/m
(7.62% per foot). The Alarm 2 activation level is programmed normally somewhere in this
range. The bar graph display will show a continually cycling pattern when the unit is in
FastLearn mode. On the command module display, this will occur when any unit on the
RS-485 communications loop is in FastLearn. Otherwise, the bar graph display on the
command module mimics the bar graph display on the highest-reading detector on the loop.
(9) Aux. Alarm, Pre-Alarm, Alarm (Fire), and Alarm (Fire) 2 indicators illuminate when the set
alarm level has been reached and the set time delays have expired. On a command module,
the indicators signify an alarm condition from any detector on the communications loop.
(10) Smoke Density Indicators (1 through 10) are the relatively scaled ClassiFire bar graph and
changes in steps of half a segment.
Display types
The standard detector display is a two-line LCD which allows basic programming
of the detector. See Figure 9.
Figure 9: Standard detector display
The command module display contains more information than the standard
detector display. The command module display instructs the user with graphic
symbols. See Figure 10.
