If you still have Advanced MxPro 4 fire alarm control panels out in the field, this is the date to put in the diary: spare-parts availability for the legacy MxPro 4 range ends on 30/06/2026. After that point, sourcing replacement boards, power supplies and other components becomes a genuine problem — so now is the time to look at the panels you maintain and decide what needs planning for.
This follows the announcement we made back in 2022, when Advanced confirmed the MxPro 4 series would no longer be sold from 2023. At the time, Advanced committed to supporting existing installations with spare parts — some for the foreseeable future, others for a limited period only. We’ve now reached the end of that limited window.
What the deadline actually means for you
A MxPro 4 panel that’s healthy and doing its job doesn’t need ripping out on 30/06/2026. There’s no regulation forcing a swap, and an installed, fully functional system can keep running.
The risk is reactive, not scheduled. If a board, power supply or display fails after the spares deadline and the part is no longer available, you’re no longer looking at a quick repair — you’re looking at an unplanned panel replacement, often at short notice and on a live site. For any panel covering a building where downtime or a costly emergency call-out would hurt, it’s worth getting ahead of that now while parts and lead times are still on your side.
Quick context on why this happened in the first place: Advanced cited increasingly scarce legacy components and the arrival of UKCA (UK Conformity Assessed) marking as a requirement for fire panels sold in the UK from 01/01/2023. Rather than re-engineer an ageing platform, Advanced put its resource into the current Go and MxPro 5 ranges.
Before you do anything: check your exposure
A short audit beats a scramble later. For each MxPro 4 panel you’re responsible for:
- Note the panel model and loop count (Mx-4100 / 4200 / 4400 / 4800).
- Record the detection protocol in use — Apollo, Hochiki, Argus or Nittan.
- Flag any panel on a critical or high-occupancy site where an unplanned failure would be expensive or disruptive.
- Prioritise replacements by risk, not by age alone.
If you’d rather not do this cold, talk to our team — working through exactly this kind of assessment is what the in-house engineers at Huvo are here for.
Your two replacement routes: Advanced Go and MxPro 5
When the time comes to replace a MxPro 4, Advanced gives you two current, UKCA-marked options. Both are EN 54-2 and EN 54-4 approved (the European standards covering fire detection control and indicating equipment, and its power supply), so either keeps you compliant with BS 5839-1 design for commercial systems.
Advanced Go / Go+ — the modern single-loop panel.
- One loop, with 15 integrated zonal LEDs.
- Go supports up to 50 addressable devices per loop; Go+ takes up to 126 (Apollo), 127 (Hochiki) or 240 (Argus).
- Apollo, Hochiki and Argus protocols.
- Next-generation PC configuration tool, USB and Ethernet on board, and digital-ready connectivity via AdvancedLive.
- A “no-hinge” door designed for quick removal — a small thing that saves real time on the fix.
One point to be clear on before you spec one: the Go has a 50-zone software capacity, but UK practice for BS 5839-1 systems calls for LED zonal indication, and the Go carries 15 integrated zone LEDs with no way to add more. In practice that makes it a 15-zone panel. For a smaller, single-loop, standalone site within 15 zones it’s an ideal MxPro 4 replacement — past that, it isn’t the right tool, and you should be looking at the MxPro 5.
MxPro 5 — the scalable, networkable panel.
- 1, 2, 4 or 8 loops, up to 200 zones on a single panel.
- 20 programmable zonal LEDs on board, with repeaters and mimic/zone-plan options to give LED zonal indication right across larger systems.
- Networkable up to 200 panels and 2,000 zones, with repeater support.
- Apollo, Hochiki, Argus and Nittan protocols.
- On-board graphic software support and third-party BMS (building management system) integration.
- Adds EN 54-13 approval (system compatibility and connectivity) — worth specifying where a project calls for it.
MxPro 5 is the route for multi-loop panels, anything that needs to network with other panels, or sites pushing past the Go’s 15-zone and device limits.
Find your replacement in a couple of minutes
Not sure whether a job calls for a Go, a Go+ or a MxPro 5? We’ve mapped out a short panel-finder that walks you through loop count, zones, protocol, networking and a few other essentials, then points you to the right replacement. Try it below.
