LSN Modules
– It is possible to combine LSN interface modules, LSN detectors and notification
appliances on one loop or stub line.
– For a mixed connection of LSN classic elements and LSN improved elements, a maximum
of 127 elements are permitted.
– Limits per LSN 0300 module:
– Up to 127 LSN classic elements or 254 LSN improved elements can be connected
– Current consumption of up to 300 mA
– Cable length of up to 1600 m (see also Page 34)
– The use of unshielded cables is possible.
– Limits per LSN 1500 module:
– Up to 127 LSN classic elements or 254 LSN improved elements can be connected
– Up to 1500 mA current consumption if LSN improved elements are connected
– Up to 300 mA current consumption if LSN classic elements are connected
– Cable length of up to 3000 m
– The use of unshielded cables is possible.
– As stipulated by EN 54-2, systems with more than 512 LSN elements must be connected
redundantly. This is ensured by using a second basic housing with an additional panel
controller. A CRP 0000 A cable set is required for redundant connection.
