JBL Professional has announced that its Control 300 Series of large-format ceiling loudspeakers are now UL listed under UL1480 and UL2043. The UL listed models include Control 328C/328CT 8in. models, Control 321C/321CT 12in. models, Control 322C/322CT high-power 12in. models, and Control 312CS subwoofers installed into their corresponding MTC-300BB8 or BTC-300BB12 backboxes.
Large-format ceiling loudspeakers are sometimes installed into spaces where the area above the suspended ceiling is utilized as a return air plenum for the air handling system. In many jurisdictions, speakers installed in these locations require UL1480 listing. This UL1480/2043 listing means that Control 300 Series models can now be utilized in jurisdictions requiring safety agency certification for such installations.
“We are very pleased to announce that the Control 300 Series loudspeakers are UL listed,” says Rick Kamlet, director of marketing, commercial sound, JBL Professional. “These loudspeakers and their backboxes were designed from the beginning to meet the requirements of UL1480 and UL2043, and we are delighted that systems integrators can now start utilizing these outstanding high-fidelity loudspeakers in jurisdictions requiring UL listing.”
UL1480 and UL2043 standards apply to commercial and professional audio systems providing non-emergency sound reinforcement and reproduction in accordance with NFPA 70. According to these sections, “Speakers intended for use in air-handling spaces in accordance with Installation of Air Conditioning and Ventilating Systems, NFPA 90A, shall comply with the requirements in this standard and the requirements in the Standard for Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces.”
