[labnetwork] Toxic Gas Monitoring Systems

[David A. Bunzow]

Hi Jerry,
We have two systems at The Molecular Foundry, an older Honeywell Analytics 
(about 6-7 years old and a newer system (1-2 years old).

They operate similarly to what you describe, except ours can be read remotely in 
locations immediately outside the lab enclosure where sensor are located, as 
well as at kiosk-type video panels that allow the FD to see what is in alarm, 
where its located, and the detection level (the FD likes this since they can 
make a determination of how to proceed without visiting the detection location).

Hope this helps...
