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.
