Air conditioning gas detection systems are used in a number of ways. In air conditioning plant rooms Gas Detection Australia has gas sensors and gas detectors for Ammonia , Propane, CO2 and R134a, R123, R125, R404, R407c R410a etc. In enclosed laboratories classrooms and workspaces. The Gas Detection Australia range of flush mounted Air Conditioning gas sensors for Carbon Dioxide GDA 4360 are used by the HVAC industry to control fresh air input into rooms and modulate supply. In the case of VRF systems needing room air conditioning gas detection HVAC industry uses the flush mounted GDA 3160 which are unobtrusive and used to detect low levels of R134a, R123, R404, R407c, R410 etc.
Meets the requirements of AS/NZS 5149.3:2016 and ISO 5149-3:2014

Designed, manufactured and supported locally in Australia.
The GDA 3100 Refrigerant Gas Detector uses the latest in NDIR techniques for detecting a wide range of refrigerant gases and is immune from cross sensitivity to other gases. In addition it is immune to changes in humidity and temperature with a longer lifespan then standard semiconductor sensors.
Designed, manufactured and supported locally in Australia.
The GDA 3160 is a low profile wall mounted refrigerant detector for use in offices and laboratories where a gas sensor needs to appear non obtrusive. The sensor uses the lastest in NDIR techniques for detecting a wide range of refrigerant gases and is therefore immune from cross sensitivity to other gases.
Designed, manufactured and supported locally in Australia.
The GDA 4350 is a 3 wire Non Dispersive Infra red (NDIR) Carbon Dioxide (CO₂) sensor. It gives a 4-20 mA, 0-20 mA, 0-5 V or 0-10 V o/p over the range of the sensor. Low Temperature version available.
Designed, manufactured and supported locally in Australia.
The GDA 4360 is a 3 wire 4-20 mA Non Dispersive Infra red (NDIR) Carbon Dioxide (CO₂) Sensor. It gives a 4-20 mA o/p over the range of the sensor. Designed for applications where low profile intrusion into a room space is required.
Designed, manufactured and supported locally in Australia.
The GDA7228 Flush Mount Oxygen gas sensor is a 2 wire 4-20 mA Loop Powered device with a range of 0-25% vol Oxygen.
Designed, manufactured and supported locally in Australia.
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 GD 4508/16 is a 1 to 16 point gas sampling system for use in commercial buildings to control fresh air make up in rooms relative to external fresh air. Available for: Carbon Monoxide (CO), Oxygen (O₂) or Carbon Dioxide (CO2).
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.
Designed, manufactured and supported locally in Australia.
The GDA 4080 Gas Detection Controller is designed to be to take up to eight 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 caters for up to 8 GDA Sensors. The controller selects the highest reading from the sensors and displays the highest reading and is used when all the gas sensors are the same type. It is particularly useful in perimeter monitoring and car park ventilation control.
Designed, manufactured and supported locally in Australia.
The GDA 74002 is a Extended Mimic Large Character Display . These are designed so that users may view the gas level and alarm status clearly from any point. The colour of the LED back light changes depending on the alarm state of the GDA 4080 control unit.
Designed, manufactured and supported locally in Australia.
The MS001 uses one of the alarm relays from a GDA gas detection controller to drive the AVR-20R/YM sounder & flasher. The sounder- flasher can be muted by incorporating the MS001 into the output switched 24 VDC from the control panel.
Designed, manufactured and supported locally in Australia.
This small potted Isolator is used for the protection of 4-20 mA signal lines against high voltage breakthrough and ground loops that give rise to noise problems. It is designed to be mounted inside or adjacent to control equipment. Cable Interface is via plug and socket.
Designed, manufactured and supported locally in Australia.
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.
