Wireless interconnected photoelectric smoke alarms are the preferred residential fire‑safety solution for European distributors, property developers and smart‑home brands. Leading Chinese OEM/ODM manufacturers—including Ariza Electronic and ANKA Security—supply EN14604‑based models with 433MHz/868MHz RF interlink, 10‑year sealed lithium or replaceable DC batteries, ≥85 dB sound at 3 m, hush/test functions and optional Tuya WiFi/smart modules.
Why Wireless Interconnected EN14604 Alarms for Europe
- Whole‑home coverage: when one unit detects smoke, all linked alarms sound simultaneously. Ariza public models list up to 30 interconnected units; ANKA RF models list group interlink by model (e.g. 20–30 units depending on firmware).
- No wiring: ceiling‑mount RF devices reduce installation time in retrofits, rentals, hotels and apartments.
- EN14604 compliance: harmonised standard for standalone residential smoke alarms; suppliers commonly cite EN14604:2005/AC:2008, with CE/CPR documentation per model.
- Smart upgrade path: Tuya/Smart Life WiFi, Zigbee, NB‑IoT or RF gateway options enable app push, device status and integration with security systems.
- Low maintenance: 10‑year sealed lithium eliminates battery replacement; 9V/AA options remain available for budget retail.

| Sound output | ≥85 dB(A) at 3 m; red LED and buzzer alarm indication |
| Functions | Test button, hush/silence, low‑battery warning, end‑of‑life indicator on selected models |
| Smart options | Tuya/Smart Life WiFi, optional RF+WiFi, Zigbee/NB‑IoT/CAT1 by factory roadmap |
| Environment | Common -10°C to +50°C; humidity limits vary by model (e.g. ≤93–95% RH) |
| Compliance extras | CE/CPR for EN14604; RED+EMC for RF/WiFi; RoHS/Reach; regional marks such as AS3786/UKCA/BSI/LPCB subject to model |
China OEM/ODM Manufacturers for Wireless EN14604 Smoke Alarms
1. Shenzhen Ariza Electronic Co., Ltd.
Ariza, founded in Shenzhen in 2009, focuses on security alarm products and supports OEM/ODM for global brands. Its S100B‑CR‑W series offers EN14604 photoelectric detection, 868MHz RF and/or Tuya WiFi, 10‑year DC3V lithium options, ≥85 dB/3 m, test/hush, low‑battery warning and up to 30-unit interlink in open-field RF configurations. Wireless variants include WiFi only, RF433, RF868, or WiFi+RF combinations for distributors needing both standalone and app‑connected models.
2. ANKA Security / ANKA Sci‑Tech
ANKA supplies smart home and security alarms with wireless interconnected smoke detectors such as AJ‑762SI4 and AJ‑763SI. Public specifications include DC3V lithium 10‑year battery, 433/868MHz RF, photoelectric sensing, EN14604 and AS3786 references by model, ≥85 dB/3 m, test/hush, and group interlink (AJ‑763SI listed around 20 units per group; larger groups available by model). ANKA also develops WiFi, Zigbee, RF, NB‑IoT and CAT1 connections, making it suitable for private‑label smart fire products.
433MHz vs 868MHz vs Tuya WiFi: How to Choose
| Option | Best for | Buyer notes |
|---|---|---|
| 433MHz RF interlink | Cost-sensitive projects, simple home networks, non-EU or regional RF approvals | Cheaper modules; confirm local spectrum rules. Less ideal as default for EU without RED testing on the exact frequency plan. |
| 868MHz RF interlink | EU residential/commercial retrofits, longer stable RF, lower congestion | Preferred for Europe; request RED/ETSI reports, open-field range and max interlink count. |
| Tuya WiFi / Smart Life | Smart-home brands, app alerts, property managers | WiFi handles remote push; pair with RF interlink so local sounder network works during WiFi/router issues. |
| Zigbee/NB‑IoT (factory roadmap) | Hub-based smart buildings, large rental portfolios | Available from some OEMs such as ANKA; confirm hub compatibility and certification separately. |
European Compliance Checklist for Wireless Smoke Alarms
- EN14604 model certificate: ask for standard version, certificate number, notified-body number, model name and Declaration of Performance; do not accept “CE only” without EN14604 test evidence.
- CPR/CE marking: standalone residential smoke alarms are placed with CE under the Construction Products Regulation; keep DoP, technical file and EU representative details.
- Radio compliance: 868MHz/WiFi/Zigbee models need RED (2014/53/EU), EMC and, where relevant, RF standards; request reports for the exact module and firmware.
- RoHS/Reach: required for EU electronics; ask for material declaration and test summary.
- Sound and battery claims: verify ≥85 dB at 3 m, low-battery warning, 10‑year sealed-battery end date, and hush function on samples.
- Interlink performance: test maximum units, open-field range, indoor range through walls, and fault/low-battery propagation before tender submission.
OEM/ODM Cooperation Workflow
- Send target market, certification scope (EN14604 only, or EN14604+RED+additional marks), quantity and housing style.
- Factory recommends base model: 868 RF only, 433 RF only, RF+Tuya WiFi, or Zigbee/NB‑IoT.
- Approve sample for smoke response, interlink count, sound pressure, battery drain and app functions.
- Confirm private label: logo, color box, multilingual manual, QR code, certificate holder and DoP wording.
- Validate production lead time, QC reports, shelf life/expiry labelling and after‑sales warranty.
