Cryogenic Room Gas Detection
Cryogenic freezing using liquid Nitrogen poses a problem of oxygen depletion. The GDA 2528 oxygen gas sensor offers a cost effective method of detection and low cost of maintenance. For standalone cyro-storage chambers housed in laboratories, the storage area can be monitored for oxygen depletion by the standalone GDA 40125 system.
Designed, Manufactured and Supported in Australia.

GDA 4011 : Flush Mount Single Channel Gas Detection Controller
This is a flush wall mounted (Clipsal GPO) single channel control unit. It interfaces to all the GD a series of 4-20mA sensors. There are 3 relay o/p’s, Alarm 1, 2, and fault. These relays are SPCO. The backlit LCD display indicates current gas concentration and alarm status. There is an internal sounder which can be muted from the front panel. The unit requires 24v dc.
DESIGNED, MANUFACTURED and SUPPORTED by GAS DETECTION AUSTRALIA.
GDA 4020 : Two Channel Gas Detection Controller
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.
GDA 4080 : 8 Channel Gas Detection Controller
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.
GDA 2400 : Multiplexed 8 Channel Gas Detection Controller
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 Periphery monitoring and Car park ventilation control.
Designed, manufactured and supported locally in Australia.
M2001 : Flush Mount Mimic Panel
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, used in conjunction with the GDA 4020, GDA 2400 or GDA 4500 control unit.
Designed, manufactured and supported locally in Australia.
GDA 74001 : Extended Mimic Panel
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.
REP 2016 : Repeater Panel
The GDA Dual Channel Repeater Panel allows for simple replication of the alarm and system status of all GDA gas detection controllers by visual and auditory indicators.
Designed, manufactured and supported locally in Australia.
MS001 : Flush Mount Mute Switch
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.
DESIGNED, MANUFACTURED and SUPPORTED by GAS DETECTION AUSTRALIA.
AVR 20 : Alarm Flasher and Sounder
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.
