Single Home Design Example
Perimeter Alarm with Backup
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 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 possible
that after hearing the sales pitch you decide to just let someone else worry about
installation.  But being a wise consumer you should also 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 a
Full Perimeter
with Backup
configuration.  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
Design

  1. 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!
  2. 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).
  3. 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).
  4. A wireless wall mounted keypad (5825V) is mounted by the interior
    garage door.
  5. For convenience two wireless keyfobs (his and hers) are used to
    arm/disarm the system.  The kids simply 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!
