The Edwards 439D-10AW-R Series fire alarm bells are diode polarized, vibrating bells for use with fire alarm equipment. Also, they operate in conjunction with an installed fire alarm panel and detection devices. Besides, the steel alloy gongs have a red epoxy powder finish and produce a loud, resonant tone required in fire alarm systems.
In general, the Edwards Est 439D-10AW-R Fire Bell is a diode-polarized, vibrating bell designed for use with fire alarm control equipment. The gongs come made of select alloy steel to sound the loud, resonant tone required in fire alarm systems. They are epoxy powder-coated red.
Furthermore, the supplied mounting plate installs directly on the surface or on any single gang box, or on any 3 1/2″ (89mm) or 4″ (102mm) octagon, or 4″ (102mm) square electrical box. For outdoor installation, use Edwards Cat No. 449 weatherproof backboxes. The 438D and 439D fire alarm bells are audible signaling appliances for installations that operate in conjunction with an installed fire alarm panel and detection devices.
