RS-485 Communication Network 

Using the RS-485 network capability of the detector and communicator software, it is possible to 
connect up to 32 detectors in an addressable system with 4 wires only (2 for power and 2 for 
communication). Using repeaters, the number of detectors can be much larger (32 detectors for 
each repeater) up to 247 on the same 4 wires. Using the RS-485 network, it is possible to read each 
detector

’s

 status (fault, alarm) and to initiate a BIT to each detector individually. 

The detector communicates via RS-485 with a Modbus RTU compatible protocol. For more details on 
the communication protocol, please consult with FGD.
