Gas Testing Kits

AGS provide a range of test gas kits traceable to appropriate standards and usually consist of:
Certified gas cylinder / Spray.
Flow control regulator / Control Valve
Tube pipe / Applicator cone
All certified test gases are classified as non-flammable and non-toxic, however, they do contain gas under
pressure and may explode if heated to extreme temperatures and cause asphyxiation in high
concentrations.

Mini Merlin Gas Testing Procedure

Recommended** gas concentrations for testing your mini-merlin system.
Carbon Monoxide
250-500ppm balance in air.
Methane
6000-8000ppm balance in air (0.6%-0.8% BV)
**
Reference should always be given to any applicable national & local law and industry codes.
Generally, the gas concentration should be greater than the alarm threshold of the device.
GAS TEST PROCEDURE
1. Ensure you have the correct gas for the device type prior to application.
2. Screw the regulator/valve into the gas cylinder outlet.
3. Once sealed, the regulator pressure gauge (if available) will indicate cylinder pressure.
4. Offer up the applicator hose/cone and apply to the top vents of the device.
5. Open the valve/regulator to allow the gas to be delivered at a pre-set flow rate.
6. Apply gas.
7. The device will enter alarm status after a short period of time.
8. The device will activate all configured outputs/relays.
At this point...
9. Remove applicator hose/ cone and turn the gas cylinder regulator/valve off.
10. Once the device has returned to normal – Reset by pressing the Touch button.
11. Test complete.
12. Record your test details. There is a provision for this in this manual.
Always remove the regulator/valve after use!
All cylinders will re-seal upon removal of the regulator/valve!
Deviating from this test process is deemed improper and may affect the functional safety of your device!
Exposure to chemicals, smoke or any other materials other than the gases intended to be monitored can
seriously damage the gas sensing elements!
Always allow a minimum of 5 minutes before testing the same unit!
QUICK TIPS
To increase reaction time, cover the escape vents located underneath the device.
Alternatively, enclose the device and apply gas i.e. in an air tight bag or container.
