Consilium PG11 - 5.1.4 PG11 Function check with the Remote Gas Test kit

Operating Manual PG11 / PGE11 Page 24
Procedure:
1. If PG11 is not already fitted with a Gas nozzle , please fit this to PG11 as illustrated below at point A.
2. Verify that PG11 is fitted with an Environment Shield. Not having an Environment Shield will make the
gas dilute too quickly giving low gas reading, especially in windy conditions.
3. Connect the test Gas cylinder to the Gas nozzle as illustrated below.
4. Apply the gas from the Gas cylinder with at least 2 liters/min flow rate.
5. Observe that the detector indicator is showing gas alarm or that a gas response is received at the
control system
6. With a response of more than 20 %FS the Gas Detector has passed the test.
5.1.4 PG11 Function check with the “Remote Gas Test kit”
For gas testing of detectors mounted high up or another not easily reachable location. Kit consists of a “ Gas
nozzle ” on the nose of the detector and a “ Gas test box ” to be mounted at a suitable location. In between the
Gas nozzle and Gas test box there will be a gas pipe to allow for the gas to flow from the Gas test box and
into the Gas Detector through the Gas nozzle.
Requirements:
• Gas nozzle (if not already fitted)
• G11 should be fitted with the Environment Shield especially if there is any wind.
• Gas cylinder with same type of gas as Detector is rated to detect
o Concentration of test gas shall be above 40%FS
o Flow rate of minimum 2 liters/min.
• Flexible gas hose
Procedure:
1. Connect the test Gas cylinder to the Gas test box (illustrated below).
2. Apply the gas from the Gas cylinder.
3. Observe that the detector indicator is showing a gas alarm or that a gas response is received at the
site gas detection system. This might take several minutes depending on gas flow and the length and
diameter of the gas line.
4. With a response of more than 20 %FS the Gas Detector has passed the test.
