I want to install a wireless alarm system in my house. I've been
visiting some websites that sell them. Can anyone recommend one that
has all or some of these features:
1) Uses N-RAM so if all power is lost, even back up battery, the
system will retain its settings and not require setup again? Will
be fully operational/configured when power restored.
2) Can use your computer directly(not going through a website) to
setup/download/upload system settings?
3) Components such as Motion Sensors are reliable but not real
expensive?
4) Easily programmable, user friendly.
I am thinking of having 3 magnetic door switches and about 5 motion
sensors.
Also is there any precautions or special needs when using magnetic
door alarm switches on steel doors? I know the steel can rob some
magnetism but what if they're installed with spacers so they're
mounted about 1/2" away from door?
Any information appreciated............
Installing a system (particularly wireless) isn't as "easy" as some DIYer's may think. The features you list are pretty well "standard" in any system you get these days. DSC sells a wireless "all-in-one" unit, but I would strongly suggest that the main keypad (which is also your common control) be located somewhere other than next to an entry door. This goes for practically any of the "all-in-one" type alarms (like Ademco's Lynx, and Visonic's Power-Max). Of the three I've mentioned, all are relatively simple to program, but if you've read some of the questions posted here, you'll find that programming an alarm system requires a knowledge of alarm terminology. GE/Sentrol publish an installation handbook that will answer most of your questions regarding special applications like installing sensors in steel doors. It's geared to sell Sentrol/GE branded equipment, but the applications are pretty well universal. You can download it from the FAQ's page at http://yoursecuritysource.com.
One more thing... If you're contemplating the purchase of this equipment "online", I'd suggest you compare prices and service with one of your LOCAL alarm providers as well. Additionally, warranty may not apply to your installation unless a dealer (aka professional installer) checks your terminations prior to power-up. If you compare the cost you'll pay for shipping the equipment with the cost for a two hour service call, I think you'll come out ahead using the local dealer as your parts source.
