Page 2 of 13 1. GENERAL 1.1 Introduction This manual serves to provide only the basis operator’s information on the control and operation of the Fire Extinguishing System. To ensure continuous reliability of the system, the owner or owner’s representative should establish an agreement to carry out regular maintenance of the installation with the manufacturer or manufacturer’s representative or a competent and qualified contractor trained to service and maintain this system. The arrangements for maintenance should be such as well ensure that a qualified person is available on call at all time to provide service in the event of any fault that develops at the installation. For the requirements of the Regular Testing and Inspection, please refer to the section covered in this manual. 1.2 System Description This Fire Extinguishing System utilises the V5 Extinguishing Control Panel. The system comprises an Extinguishing Control Panel which performs the task of processing the input signals and thereafter transmits the output signals or initiates other auxiliary functions. The Extinguishing Control Panel usually sited outside the Protected Room clearly visible from the entrance. Input devices are used to cause a change in panel status. These devices may be the combination of Heat/Smoke Detectors, Remote Electrical Manual Release Station, Remote Mechanical Release Control Devices (if provided), or Remote Abort Station. Output devices are used to provide an audio & visual warning. Output devices commonly used are alarm bells, electronic sounders, strobe light, “Evacuate Immediately” flashing sign and “Gas Discharged” flashing sign. These three components: Input Devices, Control Panel and Output Devices form the basic function of the Fire Extinguishing System. The detection of Fire Extinguishing Systems operates on a “Dual Risk Zone” basis. These zones are groups of input devices grouped in accordance to the locality they are protecting. In the event of a Fire/Fault condition, the location where the signal had originated will be defined by the respective indication on the panel. It is therefore important to be familiar with the zoning of the protected area. A zoning diagram (or zone chart) is usually provided for this purpose. The Extinguishing Control Panel is provided with a feature that continuously monitoring the continuity of the input/detection, output/sounder circuits and Electrical actuator circuits to ensure integrity of the system. It is also equipped with a battery back-up supply (lasting at least 24 hours) in the event of an incoming supply failure.
