Best Wireless Fire Alarm Systems: EN 54-25 Options Compared
By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
Quick answer
For commercial wireless fire detection, Hochiki Ekho is the standout hybrid ecosystem; C-Tec's wireless range serves small-to-mid systems well; EMS (FireCell) remains the specialist heritage choice. All run EN 54-25 supervised radio onto BS 5839-1 designs — same compliance, no cables. Devices cost 20–40% over wired, installation labour drops by more in occupied buildings.
The systems worth shortlisting
All are EN 54-25 certified: supervised links (panel knows within minutes if a device vanishes), monitored batteries with months of warning, and interference resilience — the standard that separates commercial wireless from domestic radio-link alarms.
| System | Architecture | Strengths | Fits |
|---|---|---|---|
| Hochiki Ekho | Hybrid wireless on Hochiki ESP | Mesh resilience, mixes wired+wireless loops seamlessly, big ecosystem | Schools, care, heritage, phased estates |
| C-Tec wireless (ZFP/CAST) | Wireless onto C-Tec panels | Value, simplicity, strong UK support | Small-mid premises, HMO Grade A specs |
| EMS FireCell | Dedicated wireless platform | Heritage pedigree, radio engineering depth | Listed buildings, complex radio environments |
Where wireless wins the business case
- Occupied buildings: no containment runs through working offices, care homes, hotels — installs in days with minimal disruption (the making-good line alone often pays the device premium)
- Heritage/listed: no chasing historic fabric — the consent-friendly answer (see the listed-building logic in our heritage guides)
- Phased/temporary: decant buildings, construction-phase coverage, buildings awaiting remodel — redeployable devices
- Speed: 1–3 day installs against weeks wired — when an enforcement notice or insurer deadline is ticking, radio is how you comply this month
- Hybrid economics: Ekho-style mixing puts wireless only where cabling is painful — staircores wired, ornate wings radio — optimising cost per zone
Survey rigour and honest costing
Wireless succeeds on radio discipline: a pre-design signal survey (test transmitters in real positions, margins recorded), expansion headroom planned, and battery logistics scheduled (typical 3–5 year cycles, panel-reported). Skipping the survey is how 'wireless problems' folklore gets made — engineered systems run clean for years. Money: device premium 20–40% over wired equivalents; installed totals often land at or below wired in occupied/heritage contexts once labour and decoration are real numbers — our cost guide's wireless section and the dedicated wireless landing page carry worked figures. Servicing matches wired schedules (6-monthly) plus battery rounds; certificates identical — BS 5839-1 doesn't care that the loop is air.
