Two technologies to eliminate false alarms
A conventional infrared detector reacts to changes in heat. A heater turning on, a sunbeam moving across a window, or a warm draft—all of these can set off the alarm without an intrusion.
The Ajax MotionProtect Plus adds a second detection mode to the infrared sensor. The alarm is triggered only when both sensors confirm the same event, which eliminates most heat-related false alarms.

Where to install it
Sunrooms and rooms with lots of windows, spaces with convection heating, garages, workshops, and areas with drafts—anywhere a standard MotionProtect has already proven to be too sensitive.
In a typical living space,the standardAjax MotionProtect is sufficient.
