2.1. Product Overview
The AT-MGS-408 Gas Detection Controller displays comprehensive and centralized
information about the status of all connected gas detectors. A maximum of eight
AquiTron gas detectors can be connected to the AT-MGS-408 via Modbus RTU.
Compatible gas detectors are:
• AT-MGS-410
• AT-MGS-550
• AT-MGS-450
• AT-MGS-460
The AT-MGS-408 can be used to provide power to each connected, compatible gas
detector, negating the need for separate power supply at the location of the gas
detector.
The AT-MGS-408 displays status via an LCD screen and a bank of LEDs that
represent the channel / sensor connected to it. Each channel / sensor has a row of
dedicated LEDs to indicate the status of the sensor:
• Power
• Low alarm
• High alarm
• Fault
The LCD screen will display the current gas reading and gas type for the selected
channel, or will indicate fault and/or alarm status. The LCD screen is also used for
configuration of the AT-MGS-408 via the integrated keypad.
In addition to the LED alarm status, the AT-MGS-408 includes an integrated audible
alarm. An optional beacon can be installed, mounted in the top of the enclosure, to
enhance local alarm indication.
The AT-MGS-408 provides relays
(indicating any high alarm, low alarm or fault status)
and
can act as a Modbus slave device. This allows connection to a third-party device such
as a Building Management System
(BMS)
or Programmable Logic Controller
(PLC)
.
Data logging is available on the AT-MGS-408 via the integrated SD card, which can
be removed to allow download of the logged data to a computer. The data will
