2.8 Special Conditions for Use with Reactive Gases
If using a Test Stand and Cylinder Holder for calibrating or bump testing a gas Detector config-
ured with a chlorine or ammonia sensor:
- Place the chlorine or ammonia gas cylinder in the Cylinder Holder closest to the Test Stand.
- Only one reactive gas Test Stand is allowed in a bank.
- If connecting other Test Stands to the right of the reactive stand, plug the reactive gas outlet
port with a white gas plug before mating the next Test Stand. Otherwise, inaccurate calibration
could result on the reactive sensor.
- Before the first use with reactive toxic gas, condition the regulator and Test Stand with the gas,
by running the calibration twice in sequence. If using chlorine, perform this procedure daily be-
fore use.
If not using GALAXY GX2 Cylinder Holders:
- Use a dedicated pressure regulator on the reactive toxic gas cylinder (for chlorine or ammonia,
use P/N 10034391). Label the pressure regulator "FOR CHLORINE USE ONLY" or
"FOR AMMONIA USE ONLY", as applicable (label stickers are provided with regulator).
- Use the shortest possible tubing running from the reactive toxic gas pressure regulator to the
Test Stand's "CYLINDER 1" port.
- Before the first use with reactive toxic gas, condition the regulator and Test Stand with the
gas by running the calibration twice sequentially; for chlorine, perform this procedure daily be-
fore use.
- Many gases have a cross-sensitivity to other gases. Ensure that test cylinder gases do not
contain other interfering gases.
Do not use the GALAXY GX2 to calibrate or bump a gas detector with a chlorine dioxide (ClO

)
sensor.
