Optronics PG11 - Function Check with the Remote Gas Test Kit

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:
● PG11 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
○ Concentration of test gas shall be above 40%FS
○ 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.
