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 design ideas from
some seasoned security professionals, familiarize with professional-grade
hardware offerings, and more importantly give you an idea of total cost of a fully
installed alarm system. I don't like wasting the local dealer's time but you should
get multiple estimates anyway and not everyone gets a sale. Of course it's
possible that after hearing the sales pitch from each you decide to just let
someone else worry about installation. But being a wise consumer you should
also look at the cost of DIY. Remember to compare equipment pricing, labor
charges as well as Central Station Monitoring fees (and their commitment period).
The first design example is for a typical Single Family home. The assumptions are
- Convenience and ease of installation of a Wireless alarm system
- Perimeter with interior backup system configuration
- 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 Kitchen area. Because the main keypad/panel is
mounted adjacent the Utility Room access to 110VAC power and
telephone line is simplified. As an alternative the LynxR Desk Mount
adapter can be utilized rather than wall mount.
- Each perimeter opening (door and window) is protected by a wireless
contact/transmitter. The internal contact is used for all transmitters
with the exception of the overhead garage door (external 958 contact
is connected to 5814 transmitter).
- Two PIR motion sensors with pet immunity (40 lbs.) are used to
backup the door/window sensors in the event entry is attempted
through a glass window (without opening the window). 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).
- A wireless wall mounted keypad (5825V) is mounted by the front door.
- For convenience two wireless keyfobs (his and hers) are used to
arm/disarm the system. The kids simple use the main keypad (or
order additional keyfobs).

As a simple cost comparision Dealer installed pricing (parts and
labor) range from $1,350 - $1,850 plus $19.95 - $27.95 per month
for Central Station Monitoring. Most dealers require a 3 - 5 year
commitment as well.
Compare this with under $1,100 for the equipment, a Saturday DIY
installation and UL Central Station Monitoring for just $9.95 - $11.95
per month - and no long term commitments!
