Addressable Gas Detection System Manual
Addressable System Manual
13
Issue 2, January 2015
The power supply to the detectors (and IN and OUT modules on the bus) must be
connected with a 2-core wire with adequate section based on the number of
connected devices, their distance from the power supply and each device’s
consumption (please see the technical manual enclosed with gas detectors for this
purpose).
Note: each detector connected on the RS485 line must have its own unique address
between 1 and 247. Please see the gas detector technical manual for address settings.
