The RS42-EZ is a 4-inch, coaxial speaker with BroadBeam Ring™ technology for consistently smooth high frequency sound, designed for open-ceiling applications. Hanging hardware includes galvanized steel cables and a built in hanging bracket with a screw on cover plate for fast, easy and secure installation. Unit may be hung or mounted direct-to-conduit via locking cover plate. The enclosure is constructed of injection molded ABS with glass fiber reinforcement for lasting durability in indoor or outdoor applications. The RS42-EZ speaker utilizes a 4 position ceramic terminal block input connector and a 6 position tap switch with transformer bypass position and has a 16 ohm impedance for easy daisy chaining in low voltage systems. The ceramic input terminal accepts up to 10 gauge plenum rated signal wire and includes thermal fuse. The RS42-EZ is suitable for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8. Hanging hardware, weather plug, cover plate, and AC-RSEZ-HH-10 are included.
