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.

Thanks for the info Frank. I've downloaded the handbook you
mentioned. Yes, I'd definately be hiding the main unit somewhere. My
neighbor had a Honeywell/Ademco installed by ADT. Its control panel
is 2 feet from the front entry door! Yikes!

Initially I don't plan on having the system monitored by a Central
Office. I will have it dial my cellphone. If after all is working I
might get monitoring but to me, unless you have a GSM module, its too
easy for the telephone line to get cut.

Thanks again for the input. I certainly appreciate it.
