Honeywell Home 951WG-WH - 3/8 in Diameter Miniature Press Fit Magnetic Contact, White Installation Notes

5800 Series contact — compact 345 MHz one-way wireless door/window sensor (5800MINI, 5816, recessed variants) for VISTA with receiver, Lynx, and compatible panels.

On Honeywell systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

At a Glance

What This Device Does Well

Provides reliable supervised status at the panel and Total Connect 2.0 when installed, enrolled, and range-tested correctly.

Before You Service or Replace One

• Sensor SKU — 5800 Series one-way vs SiX two-way encrypted vs hardwired.
• Panel online — resolve panel AC/cell trouble before blaming sensor.
• Range — 5800RP repeater or move 5881EN/6160RF receiver path for distant zones.
• Battery type — use listed cell; replace all batteries in multi-cell devices.
• Tamper — cover fully closed before declaring hardware fault.

Pre-install checklist

• Confirm panel model (VISTA/Lynx/ProSeries/Lyric) and encryption requirements.
• Verify dealer cell account and module SKU before cell install.
• Document installer code and existing zone map for takeover jobs.
• Plan antenna routing (ANT5XL) when panel location has poor cell RSSI.
• Have listed batteries and tools for sensor mounts before enrollment.

Typical install sequence

1. Mount and power panel; apply firmware updates per dealer bulletin.
2. Install cell module and run communication test / Total Connect 2.0 activation.
3. Enroll wireless sensors via installer Learn mode; label zones.
4. Include Z-Wave devices after excluding from any prior hub.
5. Install 5800RP repeater or optimize receiver placement before fringe 5800 sensors.
6. Run walk test, user code training, and central station test if monitored.

5800 contact alignment

• Gap between sensor and magnet must be within spec — too wide reads open.
• Use spacers on uneven trim; verify tamper clears when cover closed.
• For encrypted SiXCT, enroll on ProSeries/Lyric learn mode support enabled.
