6 Description and Operation Manual 2. Technical Introduction The fire gas detectors GSME of the ADICOS series serve for the detection of smoldering and open fires. The selective recording of smoldering fires is based on the principle of recognizing fire characteristic gas emissions. To test the function of the gas detectors the fire typical gas emissions have to be simulated with the aid of a Test Unit. To be able to utilize the total capacity of the GTL 100 Fire Detector Test Unit and to carry out correct test you should get acquainted with the operation of the Test Unit. The operation of the Test Unit is simple and safe. A testing procedure only takes a short time. With the aid of directly generated pyrolysis gases (low temperature carbonization gas), which are generated in the Test Unit, all types of ADICOS fire gas detectors can be safely triggered. Especially the detector types GSME-HC or L1 can be triggered, as they do not react to the gases CO or H 2, but to fire specific hydrocarbons. Remark: Please read the installation and operation manual before installation and initial operation of the units or the total system. Understanding the operating principle and the interfaces within the fire detection system of the units makes it easier to eliminate errors in case of faulty installation or in case of malfunctions caused by unfavorable marginal conditions. ATTENTION Electro-static conditions may endanger components Follow handling procedures The unit contains assemblies that are sensitive to electro-static conditions. Installation, repair and service have to be carried out by expert personnel. Electrostatic discharge when touching the internal assemblies may lead to the destruction of components. When replacing the sensor head special care has to be taken to avoid electrostatic discharges, as the sensor head contains electronic components that may be destroyed by electrostatic tensions. Damages of this kind are not covered by the guarantee. A0026_00 GV 5

7 Description and Operation Manual 3. Application Due to the special construction of the Test Unit it is possible to reach and test even detectors, which are placed in hard-to-get-to reach installation positions. The test includes the complete check of the gas sensors in the sensor head. The fire detection system remains in the normal operation mode during the test. It has to be ensured that the alarm messages of the respective fire detectors forwarded during the test do not lead to the release of a true fire alarm. Therefore all messages have to be recorded separately. Special Characteristics: low weight operation not depending on the power supply telescope pipe with long extension arm directly generated pyrolysis gases (low temperature carbonization gas) simple and safe handling safe release of the fire gas detectors Example: The detectors installed at the ceiling can easily be reached with the telescope pipe 6

The incense rod generates fire gases for a period of approximately 2.5 hours. Remove the holder for the safety cylinder out of the combustion pipe to replace the incense rod. Take off the filter cap at the other end of the protection cylinder. Remove the holder and insert a new incense rod. Remarks: Install the incense rod upright and make sure that it is well secured. Do not simply throw smoldering incense rods on the floor. Always throw burning material into a fire-proof container or into an ash box Only use specified incense rods and filters Make sure that the incense rod has been lit correctly before you place it in the Test Unit. Otherwise the rod may go out again in the Test Unit. Store the material free from humidity at in a dry place. A wet incense rod is hart to light and goes out easily. 9

11 Description and Operation Manual 6.3 Replacement of the Filters Two filters are inserted to avoid that tar or similar substances settle in the Test Unit. A dirty filter should be replaced immediately. It is recommended to replace the filters after an operation period of 5 hours. In any case the filters are to be exchanged after two incense rods have smoldered away. To replace the filters remove the filter cap from the safety cylinder. Remove the dirty filters and place two new ones in the cap. 6.4 Cleaning Clean the combustion pipe after regular use. Use pure suds for cleaning. Make sure that the holes in the filter cap are always free as otherwise the incense rod easily stops smoldering. 10
