+1 for rule about which windows need contacts

comment How Do I Plan for an Intrusion Detection System?
I have never seen a glass-break detect an intrusion that a motion did not. I would rather have another motion sensor than a glass break detector.

Door and window contacts are primarily for ensuring doors and windows are closed when you arm. They should not be relied upon for intrusion detection - use motions for that purpose. Contacts should be installed on every door and window that must be closed to physically secure your home or prevent false alarms.

comment How should I wire for a security system during construction?
I disagree with omitting door and window contacts: window and door contacts allow you to check for and set rules about whether any doors or windows are or are permitted to be open when you leave home. Open windows and doors can attract theft, compromise insurance claims (theft is harder to claim than burglary), and cause false alarms from motion sensors (think wind blowing through your home). I'm not saying that you always need to close every window, but without contacts you can't systemically enforce that certain windows must be closed when you arm your alarm.

+1 for plan first. I wholeheartedly agree. My point is, coming up with a good plan is well within the capabilities of many DIY homeowners. Someone should probably as the "how do I plan for an intrusion detection system" question.

You are welcome. It's easy when the questions are well-formed.

I don't see how the cost of sensors should determine when they are installed. Sensors should not be installed until after final paint. They will be damaged by drywall installation, get paint on them, motion sensors will get dust inside their lenses, etc.

I humbly submit that in my experience it takes less time and money and yields better results to wire for all types of sensors up front according to my own plan rather than trying to find and corral the elusive "good installer".

comment Running cat 6 networking cable in the attic: what is up to code?
@used2could The code requirements for cable ratings isn't only about voltage. Flammability and their ability to spread flame and produce noxious gases is also a key factor. That is why there are different classes for plenums, risers, etc.

If you do meet with success it'd be good to answer your own question with your method so others can learn from your experience.

comment Can I use an exhaust fan instead of a hood in the kitchen?
+1 for comment on makeup air. You're going to need a large fresh air inlet somewhere to replace all that air.

+1 for 350 cfm not being enough. I have 700 cfm over a 36" and it's just barely enough preparing a big meal.

comment How can I fix an uneven and damaged transition from drywall to tile in the bathroom?
Wouldn't a piece of finishing and edge protection profile like schluter-jolly be better than just drywall and mud? It alleviates the factory edge requirement for the patch and makes that vertical vertex less vulnerable to damage from impact.

That same problem is likely to develop the whole height of that joint. So whatever you do to fix it, do it from floor to ceiling.

Have you tried google goggles image recognition search on the surface pattern? A carefully taken picture might narrow the search enough to identify the brand.

comment What should I use to secure/organize data cable runs?
Whether conduit will help depends a lot on whether the conduit goes to and from the points where you need the cable. I recommend planning out all the cabling you know you need in advance and installing it bare (without conduit). Then, if there are some obvious paths where you need the advantage that conduit provides, install it for those paths only.

Using raceway or large diameter conduit can create flame-spread paths between walls, floors, ceilings, and attics that do not otherwise exist. If you do use them, make sure you figure out where firestops need to be installed. Depending on the home type and jurisdiction you may actually be breaking code if you don't fire stop in the right spots. Also, I have never seen raceway that is part of a UL tested building assembly, so your fire insurance underwriter probably wouldn't like the idea of it being built into a wall, ceiling, or floor.
