As global fire safety regulations tighten, an increasing number of manufacturers and safety professionals are turning their attention to a previously overlooked component in smoke alarms—the casing material. Experts now agree that flame-retardant materials are no longer optional but essential in modern smoke detector design.

Smoke Detectors Must Withstand Fire to Detect It

It’s a simple fact: smoke detectors must function during the early stages of a fire. That includes exposure to high heat, airborne particles, and even brief contact with open flame. If the plastic casing fails under these conditions—melting, dripping, or igniting—it compromises not just the device itself, but the entire safety system it’s part of.

“Non-flame-retardant plastics can actually become ignition sources,” explains Mr. Victor, CEO of Ariza, a manufacturer of EN 14604-compliant smoke alarms. “That’s why we only use UL 94V-0 certified fire-resistant materials for our products.”

EN 14604 and UL 94V-0: Key Standards Driving Compliance

In both European and international markets, regulations are pushing for stricter materials compliance:

EN 14604, the mandatory standard for residential smoke alarms in Europe, includes temperature and casing performance benchmarks to ensure reliable operation during early-stage fire events.

UL 94V-0 is a flammability rating commonly used for plastics in electrical devices. To earn this classification, materials must:

• Stop burning within 10 seconds

• Not emit flaming drips

• Pass high-heat deformation tests

For brands exporting to Europe or supplying smart home solutions, meeting both standards is critical to ensure long-term safety and legal compliance.

Ariza’s Approach: Material Safety as a Core Principle

At Shenzhen Ariza Electronics Co., Ltd., flame-retardant design is not a feature—it’s a standard. All Ariza smoke detectors are built with:

• Fire-resistant PC+ABS or ABS plastics

• UL 94V-0 flame retardant compliance

• Structural design that resists melting, deformation, and ignition

Moreover, Ariza’s quality management system includes pre-certification testing for flame resistance, in coordination with TÜV Rheinland, a leading European notified body.

“Our customers—from wholesalers to system integrators—expect more than just detection,” says Mr. Vitor. “They want reliability under pressure. That starts with the materials we use.”

Summary: Flame Retardancy is the New Normal

With growing awareness of fire risks and tighter import regulations in the EU, flame-retardant materials are now a baseline requirement for any smoke alarm entering the global market.

Whether you’re a distributor, OEM buyer, or project integrator, it’s critical to ask your supplier:

• Does your product use flame-retardant plastic?

• What certifications does the casing material meet?

• How do you test fire resistance before shipping?

If the answer isn’t UL 94V-0 or EN 14604, it might be time to reevaluate.
