2. Product Description

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

conguration 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

AT-MGS-408 User Manual

include a date stamp of all high and low alarms as well as all faults.

WARNING: This instrument is neither certied nor approved for operation in

oxygen-enriched atmospheres. Failure to comply may result in EXPLOSION.

WARNING: For your safety, DO NOT use this instrument in locations classied

as hazardous because it has not been designed to be intrinsically safe for use

in such areas.

2.2. Intended Use

The AT-MGS-408 provides audio-visual alerts and information pertaining to the

status of a centralized gas detector network. This information allows concise, at-a-

glance notication of any alarm or fault status regarding a connected gas detector

located outside the monitored space, as required by many regulatory codes and

standards.
