Overview
Honeywell wireless keyfob or panic — portable arm/disarm/panic device (5834-4, SiXFOB, related SKUs).
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.
