The GDA 40127 Carbon Dioxide Gas Detection Controller is a standalone gas detector unit with inbuilt display, sounder, flasher, relays and alarm driver using an non dispersive infra red sensor.

Designed, manufactured and supported locally in Australia.

The GDA 4020 control unit has 2 x 4-20 mA i/p with 3 associated programmable relay alarm levels per sensor. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 24 VDC.

The GDA 4080 Gas Detection Controller is designed to be to take up to 8x 4-20 mA sensor inputs and display the gas readings of the individual sensors. The multi-colour display will indicate the alarm status, levels and faults.

Designed, manufactured and supported locally in Australia.

The GDA 2400 control unit can take up to 8 x 4-20 mA I/P's. The controller selects the highest reading from the sensors and displays the highest reading of gas from the sensors. This controller is used when ALL the gas sensors are the same type. It is particularly useful in Periphery monitoring and CAR PARK Ventilation control. There are 3 x programmable relay alarm levels. There is an independent fault relay. There are 3 x analog O/P’s which can be configured for either channel as 4-20, 0-20 mA, 0-5 or 0-10 V (with resistor) O/P’s. The controller has an isolated RS485 O/P which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the push buttons located on the rear of the control board. The unit requires 240 VAC.

The M2001 is a low profile flush wall mounted MIMIC panel. These units are used on multi entry rooms so that users may view the gas levels and alarm status of each entry point for entering the room The M2001 is used in conjunction with the GDA 4020 AND GDA 2400 control unit. The M2001 derives its power and RS485 communications from the 4020/ 2400. The unit’s backlit LED display shows the real time concentration of the gas sensors connected to the 4020/ 2400 and any alarms that occur. The M2001 has an inbuilt sounder which can be muted from the front panel. The unit has two alarm relays which activate and deactivate in conjunction with the alarm status of the 4020 and 2400 control panel.

The MS001 uses one of the alarm SPCO relays from the GDA 4020, GDA 4011, or GDA 2400 to drive the AVR-20R/YM sounder- flasher. The sounder- flasher can be muted by incorporating the MS001 into the o/p switched 24 VDC from the control panel. The sounder will sound when a gas alarm occurs and continue sounding until either the alarm level falls below its threshold value or the MS001 button is pressed. The Mute function automatically resets when the alarm condition terminates.

This sounder/flashers operates at 24VDC. The sounder can be permanently disabled so that unit acts as a flasher only. These units are designed for internal use. These are available in Red or Amber.
