Below are suggestions for a single level home and a two storey home

Red spots.  PIR Sensors
Blue spots.  Door/window sensor

Green. Smoke detector

When deciding on sensor locations, it's all a question of priority and of course, budget.

In the example on the left,
First three PIRs would be located in: 

·  1. Kitchen/family/meals.
·  2. Entry/gallery
·  3. Lounge

(In an older style 3 bedroom home with hallway then the third sensor would be located in the lounge covering entry) ·  Next PIRs would be in room with valuables such as main bedroom study or garage or outside sheds with tools etc. If using door/window sensors, priority locations are rear and side where intruders are generally out of sight of neighbours. You can arm these while home.

One of the advantages of door/window sensors is the alarm and dialer is activated before intruders are actually inside.

In a two storey home, the first three PIRs would be located in:
·  1. Entry
·  2. Family/kitchen/meals
·  3. Upstairs

Location priorities of other sensors are similar to a single storey home.
