Description

The Consilium Salwico NS-Isolator-A N1790 is an IS isolator, used in combination with Salwico IS addressable detectors and manual call points. The NS-Isolator-A N1790 contains an IS-Isolator and a LISA-2 connection board.

The NS-Isolator-A is located in non-hazardous areas and forms the interface to the IS detectors and other IS line units. To each addressable detector loop a maximum of five ISOLATOR-A units can be connected, each of them accommodating up to 20 IS line units.

The Salwico NS-Isolator-A does not need a separate power supply or earth connection. It is powered directly from the fire alarm panel via the loop cable, meaning no extra cables are needed.
