Hazardous Areas (IEC Ex Certified)
IEC Ex approved gas detectors and sensors for use in Zone 1 and Zone 2 areas within Australia for both Toxic and Flammable gases.
Hazardous Areas are areas in which an explosive gas atmosphere is or may be expected to be present, in quantities such as to require special precautions for the construction installation and use of equipment construction, installation and use of equipment. Hazardous areas are classified into 3 zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:
- Zone 0 - Area in which an explosive gas atmosphere is present continuously or for long periods or frequently.
- Zone 1 - Area in which an explosive gas atmosphere is in which an explosive gas atmosphere is likely to occur in normal likely to occur in normal operation occasionally.
- Zone 2 - Area in which an explosive gas atmosphere is not likely to occur in normal operation but, if it does occur, will persist will persist for a short period for a short period only.
- Non hazardous area (safe area) - A non hazardous area is an area in which an explosive atmosphere is not expected to be present.
As per IEC60079-10-1 and AS/NZS 60079.29.2:2016
SENKO SI-100 : Explosion Proof Gas Detector
SI-100 is an IEC Ex fixed gas detector installed where potential gas hazard occur to measure and monitor oxygen, toxic gas and combustible gas. Through the LCD display the SI-100 shows the concentration of gases present and the status of the unit in real time. It can be connected to a controller with a standard 4-20mA analog output communication. With magnetic buttons a Hot Work permit not required for calibration with no need to open the device.
SENKO SI-100C : Explosion Proof Gas Sensor
SI-100C is a IEC Ex explosion proof gas sensor ready to installed hazardous and non-hazardous areas to prevent gas hazards caused oxygen depletion, toxic gas or combustible gas. Available to detect over 25 different gas types, see Ordering Information for details.
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 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.
GDA 4080RD : Remote Display
The GDA 4080RD Remote Display is a flush mounted multi-colour display will indicate the alarm status, levels and faults in a remote location from the main GDA 4080 Control Panel
Designed, manufactured and supported locally in Australia.
MS001 : Flush Mount Mute Switch
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.
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.
IS-A105N : Intrinsically Safe Alarm Sounder
The IS-A105N is a high output, 105dB alarm sounder. Suitable for all intrinsically safe signalling applications including fire, security and process control.
IS-L101L : Intrinsically Safe LED Beacon
The IS-L101L unit is an intrinsically safe field mounting beacon which provides a bright
flashing warning signal.

SENKO SGT : Disposable Portable Single Gas Detector
The SENKO SGT is a low cost disposable sensor, guaranteed 2 years operating life without recharging or calibration required.
SENKO MGT : Portable Multi-Gas Detector
MGT is a Portable Multi-Gas Detector engineered for personal protection and use in confined spaces detecting Oxygen (O₂), Hydrogen Sulphide (H₂S), Carbon Monoxide (CO) and Combustible Gases
