PRODUCT OVERVIEW

TOMAR Electronics 125dB (A) alarm horn. The D1xS2F is a high output alarm sounder with re-entrant flare horn. Low current consumption and high SPL in a robust Type 4/4X, IP66 marine grade, corrosion proof aluminum enclosure ensure the D1xS2F is suitable for all Class I & II Division 1, Zone 1 & 20 explosion proof signaling applications.

The 24V DC version is approved for public mode fire alarm use and the 110-240V DC version for general signaling use. Featuring 64 alarm tone sounds, each of the available 4 stage/channels can be remotely triggered. 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 threaded flameproof joint simplifies both installation and routine maintenance.
