GLOSSARY

Here are a few terms that will be help- ful to understand as you read this man- ual.

Arm and Disarm — Terms for on and off. When you arm the system, you turn on protection. Disarming the sys- tem turns off protection.

Away Mode — Your system’s armed mode when all sensors (including mo- tion detectors) are armed.

Console — The system’s main control panel.

Entry/Exit Delay — A setting on the hand-held remote control that allows you time while entering and exiting your house before the system arms or the alarm trips.

Home Mode — The system’s armed mode when only doors and windows are armed (not motion detectors). This prevents you from accidentally tripping the motion detector(s) yourself as you move around the house.

Instant Mode — A way of arming the system so the alarm immediately trips if a wireless sensor transmitter set to INSTANT or the motion detector reports an intrusion.

Note: The keychain remote control only arms the system in the instant mode.

Motion Detector — Senses motion by detecting a change in temperature when an intruder walks across its path.

Remote Control — A device that lets you arm and disarm the system away from the console.
