The GDA 74001 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 74001 is used in conjunction with the GDA 4080 control unit.

Designed, manufactured and supported locally in Australia.

The GDA 74001 backlit LED display shows the real time concentration of the gas sensors connected to the GDA 4080 and any alarms that occur. The colour of the LED back light changes depending on the alarm state of the GDA 4080. The unit has three alarm relays which activate and deactivate in conjunction with the alarm status of the GDA 4080 control panel. 

The unit derives its power and RS485 communications from the GDA 4080.

The number of sensor values displayed can be adjusted in the field to suit the sensor display requirements of each room.

The GDA 74001 has a dedicated Repeater Panel (REP2016) output. The Repeater panel can be used when the GDA 4080 controller is located on a separate floor. The Repeater panel can be placed on the outside of a room to indicate gas alarms inside the room. The GDA 74001 is placed inside the room to display the gas concentration value present in the room.

  • Flush Wall Mount Profile
  • Display gas concentration in real time
  • Display alarm status in real time
  • Local alarm relays reduce wiring requirements to local loads such as sounders
  • Multi drop RS485 line means that up to 32 GDA 74001 can be used off one GDA 4080 control unit.

Refrigerant Plant Room Monitoring

Refrigerant gases are used to provide a means of cooling the evaporators in freezers and air conditioning for plant rooms and chiller plants. Historically CFC refrigerant gases such as R11, R12 and R22 have been used. CFC’s are ozone depleting gases and are now being phased out and replaced by ozone friendly gases such as R134a, R407 and R410a.

Why is there a need to detect them?

  • All these gases are toxic at relatively low levels. Prolonged exposure to these gases is hazardous and results in serious health risks. GDA sensors can detect these gases at very low levels, in order to prevent this hazard becoming a danger to life.
  • Air conditioning systems and chillers that are leaking their refrigerant gases are not performing to maximum efficiency. The major use of refrigerant gases is in the re charging of these systems. If leaks are detected early the problem can be alleviated much quicker, saving costs on replacement gas, co maintenance and protecting the environment.
  • Gas detection at low levels (part per million) will give an early warning of leakage, therefore safeguarding life and maintaining the efficiency of the plant.

Gas Detection Australia has a range of ultra-low level refrigerant gas leak detection systems specifically developed to prevent the expensive results of refrigerant gas leaks for R22, R123, R134a, R404, R407, R410a, R514a, R1234yf and many others.

Battery Room Monitoring

The SI-100C and a range of associated Gas Detection Australia controllers can be used in battery room gas detection  to detect hydrogen in battery rooms and sound alarms. The battery room gas detection systems comprise of a hydrogen gas sensor SI-100C and a gas sensor control unit. The Gas Detection Australia control unit  GDA 4020 or GDA 4011 is situated external to the battery room to display the gas concentrations and the alarm status. The battery room gas detection system can then be interfaced to extraction fans, sounders or other apparatus. For smaller battery charging rooms the standalone GDA 40126 can provide an integrated sensor and controller with outputs to drive extraction fans and sounders.
