Explosion Proof Detection

Sounds like a wild goose chase into a dead end.

Yep. Still figured I would give it a shot. If they had not turned down the cost on the video system I would be a little more gungho on the detection stuff. I can't see how detection would be cheaper... and work.

Why explosion proof, isn't it outside?

Because its an environment with flash potential. Yes its outside.

Well, no s*it.

Instead of "explosion proof", search for Class div 1. Like...

Class div 1 motion detector

SDI-77XL2-EX-OUT - MSRP: $3,270.00 Outdoor Explosion-Proof Stereo Doppler Microwave Intruder Detector

The SDI-77XL2-EX Model of Stereo Doppler was developed to protect Hazardous Locations due to the presence of flammable gasses or vapors, combustable dusts or easily ignitable fibers or flyings. The SDI-77XL2-EX electronic assembly is configured to be easily inserted into a special explosion-proof enclosure. The unit is suitable for applications in Hazardous Locations under the following classifications: Class I, Div. 1 & 2, Groups C,D, Class II, Div. 1 & 2, Groups E,F,G, Class III, NEMA 7CD, 9EFG. The unit is suitable for installations at petroleum refineries, chemical and petrochemical plants, storage areas and other processing facilities where hazardous substances are handled or stored.

Atleast one of my competitors reads this group. I do not like to be too specific about clients.

WOW ..... that's some price tag!

If the guy was sqawking at a video system price, a couple of these ought to give him cardiac arrest!

I agree. All in one cameras listed as explosion proof are not much more than regular all in one weatherproof cameras of similar video specs.

I know when I do regular electrical work and its explosive proof in nature it runs 4 to 6 times the cost of normal work. plus you have all the special seals and elbows and fittings which run hundreds of dollars. I did a job where we installed a Mineral Spirits distillation unit and we where able to keep main controller on a wall of the next room so it was out of the explosive zone but all pipes in and out had to be sealed etc. to prevent vapors from migrating from one room to the next. Those seals must also be used even with low voltage runs if there is a chance of a spark .

they want "Explosion Proof" and their inside a town with "walking traffic on two sides" ?!! how in the hell did they get a permit to do that?

I've done the explosion proof stuff for a defense contractor and their first thing was to be wayyyyyy far away from people.. See which codes their using to base their call for that type of devices.. They maybe looking at the wrong specs...

@newsfe22.iad...

Every gas station has explosion proof fitting and such, and there are plenty of them inside a town with "walking traffic on two sides"

and we have ass hole gas station owners around here who let fireworks be sold in there lots and fire inspection does nothing to boot.

those electrical fitting you reference are seal-tite, for hard wall pipe (ment to keep vapors out of the electrical box) a fiberglass or plastic tank is not classified as explosion-proof, neither is the vent cap to the same tank..

ant "Explosion Proof" and their inside a town with "walking traffic

I wasn't referring to "sealtight" !! . I was referring to EYS and other such explosion proof fittings required on conduit where explosive vapors may be present. Believe me, I've installed more than enough to know what they are. Separating all the individual conductors with packing, mixing up a little "chico". Kind of miss it sometimes

Shhhh...

Yeppers. I looked into that stuff when I did the quote for the video system.
