What does the Kangaroo button on the sensor do?

The Kangaroo Button lets you slip out of the house or open a door without shutting off the entire alarm system. Press the Kangaroo Button and a blue light will come on. You have 10 seconds to open the door or window before the blue light shuts off and the door rearms. If you open the door/window within the 10 seconds, it will remain disarmed. When you shut the door/window you have a 1-minute grace period before the sensor will arm again.
