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 as follows:
- 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
- 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!
