Install instructions for the 2GIG-KEY2-345 4-Button Key Ring Remote, a wireless key fob for the 2GIG security system control panel.
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.
Scroll between options using the ← and → arrows. Move to the previous or next prompt with the ↑ and ↓ arrows.
Tip: Each key fob learned in uses one of the available fob sensor numbers as programmed in step 1.
WARNING: Observe correct battery polarity. Improper handling of lithium batteries may cause heat generation, explosion, or fire, resulting in injury. Replace only with the same or equivalent battery type. Do not recharge, disassemble, or dispose of in fire. Dispose of used batteries per local waste/recycling regulations.
