5.1.5 PGE11 short and medium Function check
For the Function test of the PGE11 short and medium use the PGE11 Gas Test kit as described in the
procedure below. The Function test is not taking into account variations in ambient pressure, wind or other
factors so it is not expected to precisely verify the accuracy of the detector. For better accuracy the detector
shall have been powered on in fresh air for more than 20 minutes, ambient should be around room
temperature, no wind and deviations in ambient pressure from the ideally 1013 mBar should be accounted
for in the gas measurement. This is explained in chapter 5.2 Perform a check of the Gas Detector accuracy.
Requirements:
• PGE11 Gas Test kit. Be aware that the correct type of kit is selected
o PGE11 short Gas Test kit
o PGE11 medium Gas Test kit
• Gas cylinder with same type of gas as Detector is rated to detect
o Concentration of test gas recommended to 50 ±10 %FS
o Flow rate between 1 and 10 liter/min.
• Flexible gas hose to connect between gas cylinder and Gas Test kit
Procedure:
1. Connect the tube from the Gas cylinder to the gas nozzle of the PGE11 Gas Test kit.
2. Attached the PGE11 Gas Test kit to the PGE11 as shown below.
3. Apply the gas with a flow between 1 and 10 liter/min
4. Observe that the detector indicator is showing gas alarm or that the expected gas response is
received at the control system
5. With a response of the test gas concentration ±10 %FS, the Gas Detector has passed the test
