  • Page 12 (please see the technical manual enclosed with gas detectors for this purpose). The different Multiscan++S1 unit versions can support a different number of detectors from 64 to 256. Each device connected on the unit's RS485 bus must have its own univocal address. STG/IN8 S and STG/OUT16-S module address settings are described later in this manual.
  • Page 13 Detectors with 4-20mA output Detectors with 4-20mA analog output are connected to the unit via remote 8-input modules STG/IN8-S. The modules are connected on the panel's bus to be field mounted far from the control panel. A 4-20mA transmitter requires a 3-core wire for connections: 2 wires for power supply (usually 12 to 28 Vdc but refer to the gas detector technical manual) and one wire for the 4-20mA signal.
  • Page 14 Detectors with RS485 output Detectors with RS485 digital outputs are directly connected to the RS485 bus. 4 wires are required in this type of connection: 2 for the RS485 serial bus and 2 for device power supply. For this reason we suggest you use two different wires or a single wire with suitable features as described below.

Each module must be addressed using the rotary switches on the PCB. The address must be univocal and between 1 and 255.
  • Page 18 2.1) STG/OUT16-S remote output module STG/OUT16-S remote modules are field mounted and connected to the panel via RS485 buses. They provide 16 Open Collector outputs (negative switch) with programmable functions to remotely trigger Sirens, Solenoid valves, Relays, etc. Each STG/OUT16-S module can be connected to up to 2 boards of 8 relays that convert the Open Collector output to a powerless exchange contact.
  • Page 19 2.1.1) STG/8REL relay expansion board The STG/8REL 8-relay expansion board converts STG/OUT16-S O/C outputs into voltage free changeover contact. Up to two relay boards can be connected to each output module. A relay board is directly connected to the output module (J1 connector) and a second relay board is connected to the first.
