YO5 High Output Sounder Fire Alarm Security System

Professional-grade mains-powered sounder designed to deliver reliable, high-impact audible alerts across fire, security, and industrial environments. The YO5 integrates seamlessly into existing alarm systems via relay base or module connections, making it an ideal choice for facilities that demand dependable emergency notification without complex installation requirements.

Flexible Tone Selection for Diverse Applications

With 32 selectable tones spanning 400-2,850Hz, the YO5 adapts to your facility's specific needs—from standard fire alarm signals to industry-specific warning patterns. This frequency range provides the flexibility to address different occupancy requirements, workplace hazards, and international compliance standards. Whether you need steady tones for simple alerting or swept frequencies for more distinctive emergency signaling, the tone variety ensures your warning signal cuts through ambient noise and reaches occupants effectively.

Industrial and Commercial Reliability

Built for demanding environments where audible notification must be heard reliably, the YO5 is engineered to support the rigorous requirements of commercial buildings, manufacturing facilities, warehouses, and security-critical installations. Mains-powered operation eliminates battery dependency concerns, ensuring consistent performance during extended operations and compliance with building codes that require dedicated, continuous-duty sounders.

Easy Integration with Existing Systems

The YO5 connects via proven relay modules—the Ei428 RadioLink or Ei128R Hard-Wired options—allowing straightforward integration with current alarm infrastructure. This modular approach simplifies installation, reduces downtime during upgrades, and provides installers with multiple connectivity pathways to suit different system architectures.

Why Tone Flexibility Matters

Modern fire safety and industrial alerting increasingly recognize that one-size-fits-all alarm tones fall short. Different frequencies perform differently depending on ambient conditions, building layout, and occupant characteristics. The 400-2,850Hz range covers applications requiring low-frequency penetration (critical for industrial noise) through to mid-range frequencies that meet standard temporal patterns. This adaptability means the same device can serve multiple facility types without requiring different hardware.

The YO5 High Output Sounder provides the certainty that your facility's evacuation and alert signals will be heard and understood when it matters most.
