DP 1420BS ALUMINIUM SOUND PROJECTOR DESCRIPTION The DP 1420BS sound projector are elegant and suitable for sound distribution in very large environments. These have a cylindrical fire protection steel body and an U bracket support in aluminium for the installation. The projector incorporates a 130 mm (5”) loudspeaker. It includes a transformer inside for the connection to (100 – 70 V) constant voltage lines. Thanks to its ceramic termination blocks (capable of withstanding temperatures in excess of 650° C/202 °F), its thermal fuse ( threshold: 150 °C/ 302 °F) and its fire-resistant cable, the speaker does not allow fire to move to the audio system. When connected to a 100 V line, its power can be selected among the values 20 W, 10 W or 5 W through the selection 4 inputs wire.
