Honeywell Home 5800MINI Wireless Door/Window Contact – White

The Honeywell Home 5800MINI protects a door or window without leaving a bulky transmitter on the trim. Its white housing is only 0.25 inch deep, so it suits casement windows, double-hung windows, ornate doors, and other indoor openings where the finished appearance matters as much as dependable reporting.

Three temporary status indicators make installation easier to verify: blue confirms that the magnet is within the listed 1-inch gap, green flashes when the sensor transmits, and red warns of a low battery. The single-zone contact uses one CR2032 lithium coin cell, supervises its case tamper, and is rated for indoor operation from 32 to 120 F. Metal surfaces, nearby wiring, and excess moisture can reduce performance and must be addressed during placement.

Within an Allied home security system, the 5800MINI is a clean way to add monitored opening coverage without drawing attention to the hardware. Allied confirms panel compatibility, radio strength, magnet alignment, and the programmed zone response before the sensor is put into service.
