Honeywell 5815WG Wide-Gap Door/Window Contact

Overview

The 5815WG is a wireless door/window contact designed for installations where the magnet-to-sensor separation exceeds standard 1.0" gap limits. Unlike the compact 5800MINI or standard 5815, the 5815WG accommodates wider openings without requiring dual-zone sensors or wired loops. It integrates into the Honeywell 5800 Series wireless transmitter ecosystem, transmitting supervisory, tamper, and low-battery signals to compatible control panels. This is the right choice when your door frame, window sash, or architectural detail prevents standard magnetic contact placement.

Compatibility

The 5815WG pairs with any Honeywell security panel that supports 5800 Series wireless transmitters—including VISTA control panels and compatible hybrid systems. Verify your panel's wireless receiver range; Honeywell 5800 Series transmitters deliver demonstrated outdoor range exceeding one mile under ideal conditions, though indoor walls and RF interference will reduce practical coverage. The transmitter broadcasts on the same frequency as other 5800 Series devices (5814, 5815, 5816, 5817XT, 5817CBXT, 5818MNL, 5820L), so coexistence is automatic—no frequency selection required.

Installation Notes

Position the sensor on the fixed frame and magnet on the moving door or sash, respecting the 1.0"-plus gap rating. The included magnet provides the trigger; ensure magnet alignment when the door closes. Battery is a supervised CR2430 lithium cell—when depleted, the panel reports low-battery status, alerting you to replace it before signal loss occurs. Case tamper protection alerts if the sensor is opened or removed. Mount using the included hardware; exact torque specs are not detailed in evidence, so verify mounting surface can support minor fastener loads without stress.
