    Install instructions for the 2GIG-KEY2-345 4-Button Key Ring Remote, a wireless key fob for the 2GIG security system control panel.

    Overview

    The 2GIG-KEY2-345 is a 4-button key ring remote that enables you to turn the 2GIG system on and off before entering or after exiting the home. In an emergency, it can turn on the siren and automatically call the central monitoring station. If lamp modules are installed, the fob can turn all system-controlled lights on or off via the open collector output. It also works with the 2GIG-GDR1-345 to open a garage door. The fob is powered by a lithium coin battery and fits on a keychain, in a pocket, or a purse.

    • Arm the system with no entry delay (if programmed)
    • Disarm the system

    • Turn system-controlled lights on or off (via the open collector output)
    • Other open collector output functions (if applicable)
