Tomar D1xS2F Alarm Horn Sounder-Intrinsically Safe

Introducing the Tomar D1xS2F Alarm Horn Sounder-Intrinsically Safe a robust 125dB (A) alarm horn designed for high output and versatility. Encased in a corrosion-proof aluminum enclosure with a reentrant flare horn, this Type 4/4X, IP66 marine-grade device is well-suited for Class I & II Division 1, Zone 1 & 20 explosion-proof signaling applications.

With low current consumption and high Sound Pressure Level (SPL), the D1xS2F is available in 24V DC for public mode fire alarm use and 110-240V DC for general signaling applications. Featuring 64 alarm tone sounds, each of its four stage/channels can be remotely triggered, providing flexibility in alert configurations.

Approved for gas groups ABCD in Class I Division 1, Class I Zone 1 IIC, and for dust groups FG in Class II Division 1, Zone 20 IIIB environments, the D1xS2F ensures compliance with stringent safety standards. The threaded flameproof joint simplifies both installation and routine maintenance, making it a reliable and efficient solution for diverse signaling needs.
