Installation, Operation and Maintenance Manual 1 INTRODUCTION This manual contains operation, installation, maintenance, trouble shooting and parts list information for the High Sensitivity Smoke Detection (HSSD) system. The HSSD system is designed to provide high sensitivity smoke detection for an area up to 2000 sq/m (20,000 sq/ft). Detection of smoke is achieved by using a fan to draw air from the protected area through sampling pipe network back to a Detector. The Detector will analyse the

Installation, Operation and Maintenance Manual In addition to the detector, a sampling pipe network is required to carry the sampled air from the protected area to the detector. Overall performance of the High Sensitivity Smoke Detection system is dependent upon the layout of the air sampling pipe network. Use of the “SNIFF” computerised program balances the piping network to provide for an equal intake of air at each sampling hole. For a detailed description on how to design a pipe network r

Installation, Operation and Maintenance Manual 2.3 Detector The Detector consists of a backbox with a removable cover, incorporated within the Detector are a detector head, termination board and a fan. These three items are the major elements of the Detector, refer to Figure 2.3 detailing the detector block diagram. The design of the Detector allows surface mounting, thus providing ease of installation and maintenance. Replacement of any of the detector’s main elements can be achieved without

Installation, Operation and Maintenance Manual 2.3.1 Detector Head Located within the Detector, the detector head is a highly sensitive detector utilising a laser, focussed to a narrow beam. The laser beam exits a sample chamber into an attached beam dump area which monitors the laser intensity. A receive optics assembly is mounted on the sample chamber with its optical axis normal to the laser beam axis (see Figure 2.4). A particle-size discriminator inhibits the detector from responding to l
