Installation instructions for the 2GIG-TILT1-345 wireless 345MHz tilt sensor, used to monitor garage doors, mailbox lids, pet doors, and hinged crawl-space doors.
Installation instructions for the 2GIG-TILT1-345 F/G Tilt Sensor — a 345MHz wireless sensor designed to monitor the tilt status of a garage door, mailbox lid, pet door, or hinged crawl-space door. When the sensor tilts to 45 degrees, it transmits to the control panel; it also sends a restore signal when returned below 45 degrees. Compatible with GC2 firmware 1.14 and higher.
Tools required: Phillips screwdriver; variable-speed drill with 1/16" drill bit.
For sectional garage door installation: mount the sensor near the top of the top panel of the garage door, with the mounting plate attached to the top panel and the sensor snapped onto the mounting plate. Confirm the "UP" arrow points up and the tamper tab is on the bottom.
For other applications (mailbox, pet door, crawl-space door): mount wherever convenient, in a vertical position.
To learn how to program the sensor into your control panel, see the panel's own Installation & Programming Guide.
