LK1:- LINK IF BARRIER IS USED ON FIRE CHANNEL
The Crowcon Detection Instruments Ltd. Quad Channel Module, marked Switch Position, is a four-channel input module for the gas detection system. Its switches set the detector type as source, sink (2 wire), 0-5 V or fire, with fire available on channel 1 only. A bus switch assigns the module to Bus 1 or Bus 2, and a module selector places it on channels 1-4, 5-8 or 9-12. Link LK1 is made when a barrier is used on the fire channel. The module is in Used condition.
