The SC-615BS Paging Horn Speaker is designed for both indoor and outdoor applications, as a 15 W, high-impedance (70 V/100 V lines) system. Its diaphragms employ special heat-resistant  polyamide film to prevent shape-changing moisture absorption. A minimal gap between diaphragm bobbin and magnetic circuitry slit enhances efficiency.

Mounting brackets and all external hardware are stainless steel. This, together with the horn treated with a 50-micron thick powdered paint coating, gives the speaker excellent weatherproofing and corrosion resistance. The aluminium external horn flare offers better shock resistance than resin. EN 54-24* and ISO 7240-24 certified, the SC-615BS is authorized for use in fire detection systems. It is also in compliance with BS 5839-8: 2008 14.8.
