I dont know excatly the use of end off line resistor in
Fire alarm system.
But in communication system(Profibus) we use end off
line resistor. In this system, all the communication
devices connected to the same bus in parallel. The bus
having only 2 wires and all the devices connected to
this same 2 wires in parallel.. And each communicator
devices have one address in that bus. Thats how the
server identifies the signals from that particular
device. So the extreme end of this bus cannot be kept
open. By providing an End Off Resistance, server can
know that this is the end of the bus and there is no
devices from that particular point.
