1. GE Interlogix HC600 Series Analogue Heat Sensing Cable Installation Manual Installation Manual INSTALLATION Before installing the HC600 series analogue heat sensing cable refer to the zone layout drawings and fixing arrangement drawings The following points should also be observed The cable should not be in contact with any material that will act as a heat sink and delay the sensing of the temperature increase from the area being monitored HC600 Series cable should be installed so that it is not severely compressed and is not adjacent to sharp objects that may damage the outer sheath The minimum bending radius for the cable is 6 mm Cable ties should not be used directly on the cable a neoprene sleeve should always be employed Whilst HC600 Series cable has a high tensile strength care should be taken not to place it under too much tension especially where there is a change in direction at a fixing The distance between supports should be between 0 6 m and 1 2 m dependent on fixing positions available The routing of HC600 Series cable should be chosen to avoid any local sources of high temperature e g light fittings steam pipes etc The minimum number of joints should be made in any run of HC600 Series cable and these connections should always be in a junction box Adjacent zones should overlap by a minimum of 50 mm All interposing cable between the HC600 Series cable and2. the DT650 950T Controller should have an inherent metallic screen braid sheath armour as part of its construction and this should be connected to earth to improve RFI and EMI i mmunity The connections should be made using a an interposing junction box Where a number of zones of HC600 Series cable are remote from the DT650 950T controllers a multi core cable should not be used for interconnections Individual coaxial or pair cables should be used which meet the criteria above Special guidelines for cable way protection In addition to the reco mmendations above the following should be observed HC600 Series cable should be installed to cover each cable tray or ladder rack intended for supporting cables Generally one run of sensing cable should be installed centrally above each level of tray or ladder rack with a further two runs of cable below the bottom level one on the outer edge and one on the support edge On horizontal cable routes where cables are mounted vertically the HC600 Series cable should be routed level with the top edge of the support system on the cable side On lengths of vertical racking of less than 1 metre used for carrying cables between horizontals HC600 Series cable should be located across the top of the rising group of cables Where the riser does not start at floor level a loop of HC600 Series cable should be provided at the top and bottom of the rising group of cables n the case of ca
