5800MINI Replacement
The Versa MINI-345 is a true drop-in for the Honeywell 5800MINI.
Same 345 MHz frequency, same panels, same programming, and the same ultra-low-profile body. If you've been installing the Resideo 5800MINI and finding it harder to source, you can replace the 5800MINI with the MINI-345 in minutes — nothing changes about how your technicians work, and a few things actually get easier. Below: why it's a true drop-in, what's better, and the exact steps to replace a 5800MINI on VISTA, 2GIG, and PROA7 panels.
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
Tool-free slide-off cover
The 5800MINI uses a pry-off lid — a flathead to separate the housing, pull the board, reassemble. The MINI-345 lid slides forward and lifts off in one motion. Battery service in seconds with the sensor still on the frame — no tools, no cracked housings.
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. 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.
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.
How to replace a 5800MINI with the MINI-345
Because the MINI-345 is the same 345 MHz 5800-series device in the same footprint, replacing a 5800MINI is a delete-and-enroll swap — the zone keeps its number, type, loop, and descriptor. The only thing that changes is the sensor's serial number. Here's the full procedure on a VISTA, 2GIG, or PROA7 panel:
Note the existing zone
Find the zone the 5800MINI is on and note its zone number, zone type, loop, and descriptor — you'll reuse every one of them. (On a PROA7, confirm the PROTAKEOVER module is installed with its rotary switch set to 0 for 5800-series.)
Delete the old 5800MINI serial
In zone programming, clear the 5800MINI's serial number from that zone. Leave the zone number, type, and descriptor in place — you're only swapping the device.
Enroll the MINI-345's serial
Auto-learn or hand-enter the MINI-345's 7-digit serial onto the same zone (trip the contact or remove the cover to transmit). Same loop number as the 5800MINI used.
Mount in the old footprint and walk-test
Mount the MINI-345 where the 5800MINI was (same 2.2″ × 1″ × 0.25″ body), magnet on the moving part within 1″ on wood / ¼″ on metal. Run the panel's walk test to confirm the zone faults, restores, and supervises.

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.
Ordering and availability
The MINI-345 is available for dealer and distributor purchase through WAVE Electronics — in stock and ready to ship. Replacement color covers are also available:

Frequently asked questions
How do I replace a 5800MINI with the MINI-345?
Replace a 5800MINI in four steps: note the existing zone's number, type, loop, and descriptor; delete the 5800MINI's serial from that zone; enroll the MINI-345's 7-digit serial on the same zone; then mount it in the old footprint and run a walk test. Because both are 345 MHz 5800-series sensors in the same 2.2″ × 1″ × 0.25″ body, the zone settings, loop, and mounting all carry over — only the serial number changes.
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.
