Single Home Design Example
The best way to understand alarm system layout is to look at two simple examples:
a single family home and a Condo/Twin. By looking at the floor plans and reading
my justification for sensor placement you can get a good feel for what you will need
in your situation. If you get estimates from five local security installation dealers you
will more than likely get five different designs, though you will see many similarities
in each design.
For anyone considering alarm system DIY I highly recommend getting estimates
from at least three professional dealers. This will give you some design ideas
from seasoned security professionals, familiarize you with professional-grade
hardware offerings, and more importantly give you an idea of total cost for a Dealer
Installed alarm system. I don't like wasting local dealer's time but you should get
multiple estimates anyway and not everyone gets a sale. Of course it's also
possible that after hearing their sales pitch you might just decide to just let
someone else worry about installation. But being a wise consumer you should
look at the savings of DIY. Remember to compare equipment pricing, labor
charges as well as Central Station Monitoring fees (and their commitment period).
This design example is for a typical Single Family home using an Interior Only
configuration. The assumptions are:
- Convenience and ease of installation of a Wireless alarm system
- Minimum cost and minimum labor
- 24 hour Central Station Monitoring
- Small dog (25 lbs.) that roams the house throughout the day and night
- Family of four - two teenage children
- LynxR-EN fully wireless panel with integrated keypad and siren
centrally located in Family Room area. In order to minimize
installation labor the "desk mount" option will be utilized - no fishing
power or telephone lines to the main unit. Just sit unit on end table!
- Each external perimeter door is protected by a wireless
contact/transmitter. The internal contact is used for all transmitters.
- Two PIR motion sensors with pet immunity (40 lbs.) are used to
backup the door sensors and also protect against window entry. The
objective is to force an intruder to pass in view of at least one motion
sensor before they can get to the second floor (bedrooms).
- For convenience two wireless keyfobs (his and hers) are used to
arm/disarm the system. The kids simply use the main keypad in
family room (or order additional keyfobs).
- Protection begins at the interior garage door - the garage is not
covered by the alarm system.

Central Station Monitoring. Most dealers require a 3 - 5 year
commitment as well.
Compare this with under $500 for the equipment, a Saturday
morning DIY installation and UL Central Station Monitoring for just
$9.95 - $11.95 per month - and no long term commitments!
As the number of alarm sensors increases so does the savings.
