Wireless Sensors in a bathroom..

[Julian]

I want to install a wireless sensor in a customers bathroom only because
someone actually broke into the window in the bathroom .. i cannot get a
wire there, so its either expose wire like crazy, patch a hell of a lot of
holes or go wireless.

The bathroom has a shower which is used daily (im assuming and hoping so).
They have a dsc 443 wireless receiver so they are gunna get a 443 wireless
contact. I am assuming just putting it in there will cause problems overtime
with rust, water getting in it, etc. Is there anything i can do to prevent
this or any ideas?

Ha ha almost missed that.

I wouldn't put a surface mounted tx in there. Is there a cabinet, closet or
storage anything close to the window. Even then you'd want some manner of
seal. Maybe a NEMA case. Jim puts stuff on boats, maybe he'll jump in here.

the window is in the middle of the shower.. like on that wall.. there is a
blind over it and im sure it stays down

my first was to calk it use electrical tape to try to make it air tight ..
but i dont feel like going back for poor planning.

I have had no problem putting wireless devices in the bathroom. However, I
agree with Spike in that you should not put a surface mount transmitter in
the shower window. If you insist on contacting that window, you could run a
wire to the nearest closet or area not subject to water and put your
transmitter there.

What I generally do, however, is to secure the window with a screw or a
window lock so it can't be opened, then use a glass break sensor within
range in the bathroom.

Allan

I don't think screwing any building opening closed is a good idea.

It's the steam I'd be concerned about in a bathroom and that's pretty much
everywhere unless he can put it in a linen closet or cabinet or what have
you. I've used those ITI and Ademco concealed ones and I sealed the surfaces
too but I'd put a surface mt in a weathertight case or behind a (n
attractive) wall plate.

You can install the transmitter in a small Radio Shack plastic project box,
or recess the transmitter in a plastic electrical box with a blank plate. I
recommend recessing it. Make sure you use a rubber gasket or a silicone bead
along the outside edge of the blank plate. You should also be sure to use a
hermitically sealed contact, not one with screw terminals. They usually have
12 inch leads, and come in very small sizes.

The times I have run into this situation I was able to run a wire to a
transmitter in a closet in the bath except for one time I had no possible way
to get a wire to the window so what I did was remove 2 tiles on the wall, cut
out the backer board and recess the trans in a plastic box. I was lucky enough
that the trans had no problems with trans and reception. I then mounted the
tiles on a piece of plywood, replaced, and a little grout, you could not even
tell.

How are you going to know which tiles to remove when it needs a battery?

That's brilliant. And how exactaly does one service the xmitter in
the future (provided they can find it)?

never heard of hammer and guts? ;-)

 

[petem]

Sure, but my customers got sick of fixing the holes after my "gut
feelings" were wrong.

you should have some guts training... ;-)

This is how we do this and have had no problems to date. We take the
transmitter and electronic out of the case (ITI) and use aquarium silicone
to seal up every opening in the case. We use the long life transmitter
battery package so that a customer isn't going to call us anytime soon to
change batteries. Use double sided tape to adhere the unit to the wall.
Don't use screws as this will be a path for moisture. Run a bead of
silicone around the base of the transmitter so that when the tape dries up,
the silicone will hold the transmitter in place. Snap in the electronics
and put the cover on. Make sure that the cover is sealed with some
silicone. Say thank you to the customer for their check and mumble see ya.

That is until the silicone adhesive gives way causing the sensor to fall
off. I don't care how well it is sealed a bathroom isn't the correct place
for ANY wireless sensor or device. If anything mount the sensor elsewhere
and use the external contact terminals for a switch

fill in the window, no sensor needed ))

That'll work too
