Technical data sheet
The model AGD-MC consists of a mains powered panel capable of operating up to four combustible gas detectors and
four Carbon Monoxide detectors.
Up to sixteen detectors (combustible or CO) can be connected to the AGDS-MC when used with the external transformer
pack. See separate schematic for wiring the transformer pack, designed for when more than four combustibles are to be
used.
The detectors are connected by low voltage 4 wire cable (typically telephone cable) daisy chained back to the control
panel. The sensor units may be mounted up to 100mtrs from the control unit. The complete system is designed to comply
with the latest CE Directives including the low voltage directive.
This is housed in an IP65 rated ABS enclosure measuring 183mm high x 212mm wide x 97mm deep.
This is also the power pack box size AD-PP.
The LED indications on the panel:

The LCD indications on the panel:
In the event of an alarm situation the LCD screen will display the condition that is causing the alarm and will generally
offer a solution. The LCD display will indicate for the following, emergency shut off button activated, gas leak detected
and which type of gas (with detector number).
Audible indications:
An internal buzzer is provided to give the following sounds:
Alarm, beep every 1 second.
There is an option to disable the alarm buzzer on the panel circuit board by removing a jumper plug.
Relay outputs:
Main valve relay rated at 5 amps to provide a switched live to the main solenoid valve.
230 volt rated potential free changeover alarm relay to activate a remote sounder and or beacon or signal a
BMS system.
Gas detection settings
The combustible gas detectors are pre calibrated at works to detect gas at 5% of the low explosion level
(pre alarm) and at 10% of the low explosion level (high alarm).
The CO detectors are calibrated at 80ppm for pre alarm and 100ppm for full alarm
