Advisory messages Advisory messages alert you to conditions or practices that can cause unwanted results. The advisory messages used in this document are shown and described below.
WARNING: Warning messages advise you of hazards that could result in injury or loss of life. They tell you which actions to take or to avoid in order to prevent the injury or loss of life.
Caution: Caution messages advise you of possible equipment damage. They tell you which actions to take or to avoid in order to prevent the damage.
Note: Note messages advise you of the possible loss of time or effort. They describe how to avoid the loss. Notes are also used to point out important information that you should read.
iv LaserSense 25 Aspirating Smoke Detector Installers Handbook EN 54-20 and UL compliance The installation must be designed using PipeCAD software. After designing the installation including pipes, endcaps, and sampling holes, enter the detector type.
To select the detector type, click Options Calculation options, and then select the detector from the Type drop-down list.
EN 54-20 installation Select Options Calculate, or click on the calculator icon. The software will prompt you to choose from Use set hole sizes, Best flow balance, and Max.
permissible transit time. Select the appropriate option and 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.
For the installation to comply with EN 54-20 Classes A, B, and C each sampling hole must be no less sensitive than 0.31% obs/m.
The calculation can be further refined by leaving a working detector in the protected area for at least 24 hours 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 Control 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 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. The settings of a compliant system should be recorded, as it is possible by changing certain programmable functions to make the system noncompliant. If functions are changed, it is recommended that the system is retested if continuing compliance is in any doubt.
UL installation Note: UL certified products may also contain additional approvals, e.g. FM3230.
Please refer to the product labels.
LaserSense 25 Aspirating Smoke Detector Installers Handbook v
UL 268 fire tests were passed with an installation as follows:
Total sampling pipe length: 160 ft. (single pipe) Number of sampling holes: 10
Worst-case sampling hole sensitivity as indicated by PipeCAD:
1.28% obs/ft.* Alarm factor: 1 Fire 1 alarm delay: 0 seconds These settings gave satisfactory responses to the test fires in 120 seconds or better. For the purposes of UL 268 compliance, these should be regarded as worst case values. Layouts should be planned in PipeCAD and the indicated worst-case hole sensitivity should be better than 1.28% obs/ft.*. Commissioning smoke tests should be performed to ensure that the farthest sampling hole from the detector is capable of generating a fire alarm within 120 seconds of receiving smoke.
* The results should be verified at installation by entering the installed detector's Fire 1 sensitivity (as indicated in the remote software histogram screen) into the PipeCAD “Options/Calculation options/Detector sensitivity” field and recalculating the layout results.

Content Introduction 2 Available software for the detector 2 Specifications 2 Indicators 4 Inside the detector 5 Removable terminal block connections 6 LaserSense 25 Aspirating Smoke Detector Installers Handbook 1 Chapter 1: Product and component descriptions Introduction This aspirating 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.
This 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.
Available software for the detector The Remote Control and the SenseNET software packages are available to program 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 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.
Specifications Caution: This equipment is only to be used in accordance with these specifications. Failure to operate the equipment as specified may cause damage to the unit, injury, or property damage.
(1) Alarm: Illuminates when the alarm level has been reached and the appropriate time delays have expired.
(2) Fault: Illuminates when the unit has a fault and a fault signal is being sent to the fire alarm panel. It also illuminates when the unit is isolated (3) OK: Illuminates to show normal operation when there are no faults. The OK lamp will flash during the 15-minute FastLearn period when the detector is first learning about its environment.
