Some are...but you can buy pretty ones :-) Not anymore ugly than thermostats, hvac registers, cheap lighting fixtures, etc.

No...why? You're asking good questions.

Only if you're careful...like i said getting the break-point right on a hinged side switch is tricky.

It's been my experience that recessed contacts in metal framed windows tend to get welded closed by a close lightning strike, and you'll never know unless you are religious about testing all your window switches on a regular basis (highly recommended practice, btw). Recessed contacts on sliding windows can go out of adjustment when the little metal wheels the windows slide on wear down...or fall off. They're also hard for a homeowner to troubleshoot if a magnet is out of alignment...its a service call to open the loop in the panel and find out which window in the zone is not closing/aligning properly...with a surface contact even the dumbest homeowner can look and see if the magnet is lined up...or missing.
| | > In residences I don't like recessed window contacts. | | Fair enough, but I take it that I should go ahead with these for doors. | They appear (from what I've seen of installations in friends' homes) to | be what is typically used. | | > Protect your phone line. | | Ugh! Unfortunately the phone line coming into the house is easily | reached by a 6' tall person standing on the deck at the rear of the house. | We had the phone company look at it (we'd requested that they move it) | when we bought the house. Our claim was that it presented a hazard | (based on the report about it given by our building inspector). The phone | company disagreed, and we've since contemplated paying them to move it, | but haven't done so yet.
They'll move it if you squeak louder. | | It would be interesting (for future reference, really) to find an alarm | system that dials first, and sounds the local alarm later. Or does such | a system already exist?
Some panels you can delay the dial out for a few seconds...personally I wont do that but you can do whatever you want.
good luck..and hth.
