Remote wireless switch

by automatedtrix / December 12, 2012 2:30 AM PST

I work in a large plant that has many remote sprinker systems. I am looking for an addressable wireless Sw N.O. or N.C. that when activated will connect to my wireless system and let me know whitch remote station has went off.
Any suggestions
Raymond

Any safety concerns?

I worked in an industrial design company for such things and when safety was involved you could only use wire. For monitoring that was a different issue but for safety where lives were at stake then you went wired, added horns, bells, lights and such to meet the local code.

Don't do this without checking codes.

With that out of the way there are companies that do this and can get you up to about a mile away for about 1,500 bucks per device. Installation, modification and such are of course not included.

I am just monitoring remote fire hydrant stations that have no monitoring right now. I am in the process of putting up a wireless system. So getting all the info before hand is the biggest step
Thanks

Safety requirements
by automatedtrix / January 11, 2013 3:27 AM PST

I don't know why it has to be so difficult?
First we are a remote lumber mill with our own system. At the present time every thing is in place except remote monitoring. We are locate in Canada therefore your fire hydrant requirement do not apply.
Second it is not the fire hydrants that we are wanting to monitor. It is the dry valve stations. Each station needs to be monitor for Freezing, Air Pressure and System trip.
Third we are only moniotoring secondary issues air pressure and monitoring the water bell when it maybe sounding and thermostat. We have had issues where the valve has opened because the air compressor has quite. The Dry valve is in a remote location so we sometimes do not hear it unless there is a station check. The system is still functioning properly our only issue is when this happens in the winter time things freeze up.
I could run wires to all these stations but why? When we have the technology to put in a wireless switch with an IP address attached to it and take care of it all..

CONSUMER GRADE MONITORING!!!

Not to be confused with wide temperature, below freezing or "harsh environments."

My background includes industrial electronic designs, military and more. But as time passed I have done more and more consumer grade work. For one system I used an "IPPower 9212" box. Here's a link.

Here's a power switch.

These were used in a low cost automatic tester. The temperature range was not extreme so it was OK.

You're welcome. Sorry for the long path.

But as you can imagine my background in industrial control and more has me a little gun shy about regulations and more. For the automatic testers we have a lot more leeway since it's just what it is without the usual regulations to worry about. Then again, we still have OSHA to worry about but another day, another story.
