Salwico Gas Detection System
Control M X is used as a provider of additional communication channels, additional
external communication,
or as an extension bus.
A Control M X provides the following features:
• Ethernet connection
• RS-422/RS-485 interface
• RS-232/RS-485 interface
• Two programmable relay outputs

The BusCon M Gas is a connection module for the Salwico Gas Detection System. This
module provides electric isolation for the system and backbone extension for module
Control M Gas, as well as monitors the supply voltage and the Xgas signal. The BusCon
M Gas has a 20-pin at cable connector with extended BBI interface for connection
with a Control M Gas module.

The Analogue M 4-20 is a transmitter module for a gas alarm system. This module pro-
vides four transmitter interfaces (4-20 mA inputs):
• 2-wire • 3-wire, current source • 3-wire, current sink • 4-wire
In order to avoid a massive start-up current in the system the Analogue M 4-20 module
delays the voltage output (+, SG) in the transmitter interfaces upon start-up:
• Transmitter interface 1, 0 ± 10 ms
• Transmitter interface 2, 125 ± 10 ms
• Transmitter interface 3, 250 ± 10 ms
• Transmitter interface 4, 375 ± 10 ms

The Power Boost M is designed to distribute power and supervise connections in a
gas alarm system. This module can supply: • Centralized power through a Power Boost
Loop, which is secured against interruption and short circuit. • Compensation for volt-
age drop in the cable for distributed modules in gas alarm systems • Transfer of xGas
status between the Power Boost modules on a Power Boost Loop and the system
modules connected to the Power Boost module on the internal Backbone Bus (BBI)
• External Backbone Bus (BBE) PB-485 communication between system modules. •
Protection of the External Backbone Bus (BBE) PB-485 communication between mod-
ules against interruptions and short circuits. • Supervise the 48 VDC and the PbxGas
signals (on the Power Boost Loop). • Transform External Backbone Bus (BBE) PB-485
to Internal Backbone Bus (BBI) RS-485.
