If you've been installing the Resideo 5800MINI and finding it harder to source, the Versa Wireless MINI-345 is a true drop-in alternative — same 345 MHz frequency, same panels, same programming, and the same ultra-low-profile form factor. Nothing changes about how your technicians work. A few things actually get easier.
Why the MINI-345 Works as a 5800MINI Replacement
The 5800MINI is a 345 MHz Honeywell 5800-series contact compatible with Honeywell VISTA panels, 2GIG GC2/GC3/EDGE, and Resideo PROA7 (PROA7 reads 5800 sensors through the PROTAKEOVER module). The MINI-345 runs the same 345 MHz 5800-series format and works on the same panels — it programs as a standard supervised perimeter zone with no special device type, no translator, and no added hardware.
If you've installed a 5800MINI, you already know how to install the MINI-345. Same loop, same zone programming, same supervision behavior, same 1″ magnet make-distance on wood (¼″ on metal), and the same ultra-low-profile body that mounts in the footprint the 5800MINI left behind.
What's Different — and Better
The cover slides off. The 5800MINI uses a pry-off lid — a flathead to separate the housing, pull the board, swap the battery, reassemble. The MINI-345 lid slides forward and lifts off in one motion. No tools, no cracked housings, battery service in seconds with the sensor still on the frame.
A narrower magnet for tight frames. The MINI-345's magnet housing is 0.320″ wide — about 38% narrower than the 5800MINI's 0.520″ magnet — so it mounts flush on narrow aluminum window profiles and tight frame channels where the wider magnet won't sit cleanly. Same 1″ make-distance on wood, ¼″ on metal.
The same magnet indicator you rely on. Both sensors carry the blue/green/red magnet-placement LED — blue confirms the magnet is in range, green flashes on transmission, red flags low battery. On the MINI-345 it's branded Bluefield™, but the behavior is identical to the 5800MINI you already install.
More color options. The MINI-345 ships with white, brown, or black slide-off covers (sold in 10-packs) — swap the lid to match any frame without pulling the sensor. The 5800MINI comes in white and brown only.

For Dealers Transitioning from the 5800MINI
The MINI-345 is a one-for-one replacement on any 345 MHz panel — no firmware update, no panel reconfiguration, no change to your techs' workflow. The only differences they'll notice:
- Cover removal: slide instead of pry — about a 10-second adjustment.
- Magnet-placement LED: the same blue/green/red indicator you already rely on (Versa brands it Bluefield™) — identical behavior, nothing new to learn.
- Color matching: order brown or black cover 10-packs for wood or dark frames; white is standard.
Programming, loop, supervision, and mounting footprint are identical.
Same panels, same install — with a tool-free slide-off cover and a narrower magnet.

Frequently Asked Questions
Is the Versa MINI-345 a direct replacement for the Honeywell 5800MINI?
Yes. The MINI-345 uses the same 345 MHz 5800-series format and the same 2.2″ × 1″ × 0.25″ footprint, so it programs and mounts exactly like a 5800MINI on VISTA, 2GIG, and PROA7 (with the PROTAKEOVER module) panels. You delete the old serial number and enroll the MINI-345's new serial; the zone, loop, and type stay the same.
Do I need to reprogram the panel to switch to the MINI-345?
Only the sensor's serial number changes. Delete the 5800MINI's serial and enroll the MINI-345's 7-digit serial on the same zone — the zone number, zone type, descriptor, loop, and supervision settings all stay the same. No firmware update or panel reconfiguration.
What's actually different between the MINI-345 and the 5800MINI?
Frequency, panel compatibility, body footprint, and the blue/green/red magnet-placement LED indicator are the same (Versa brands its version Bluefield™). The MINI-345's magnet is narrower, though — 0.320″ vs 0.520″ — so it fits tighter frames. The practical upgrades are a tool-free slide-off cover and a black cover option in addition to white and brown.
Does the MINI-345 work on a Resideo PROA7?
Yes — the same way the 5800MINI does. The PROA7/PROA7PLUS is a PROSiX/SiX 2.4 GHz panel, so it reads 345 MHz 5800-series sensors only with the PROTAKEOVER module installed (rotary switch set to 0). With the module, both the 5800MINI and the MINI-345 enroll as standard 5800 zones.
