HD 21EN
PLASTIC HORN SPEAKER
DESCRIPTION
HD 21EN is a plastic horn speaker suitable for
broadcasting alarm messages thanks to the
highly intelligible sound reproduction and its
environmenal resistance. The terminal
connection blocks, for input and output
flameproof cables, are made of ceramic
material. A thermal fuse protects the integrity
of the line in case of heat affecting the
speaker. It can be easily aimed towards any
direction through the adjustable wall-mount
bracket, and thanks to its IP66 protection
grade it can be installed both indoor and
outdoor.
