Pictured below is a PIR sensor based security system relay controller we recently made.

We make a lot of devices to interact with and monitor motion sensors – for example our user programmable PIR Relay Timer  designed for use with standard domestic PIR motion sensors such as the popular Honeywell IS-215T.

This controller pictured has a few added features specific to the requirements of the customer. A switch has been fitted so that the system can be armed easily when required. When the switch is closed, the user has 10 seconds to get out of the range of the motion sensor. While motion is being detected, the red LED is on, and after motion is first detected the yellow LED turns on and stays on. 10 seconds after motion is first detected the connected siren and strobe light are activated. Therefore the user has 10 seconds upon entering the protected area to disarm the system by turning off the switch (the location of which is of course unknown to intruders).

The user can programme in the duration that the siren and strobe lights will be on after motion is detected.

If you require any kind of system to interact with one or more PIR motion sensors, email neil@reuk.co.uk with details of your exact requirements.
