DESCRIPTION
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 SC615BS is authorized for use in fire detection systems. It is also in
compliance with BS 5839-8: 2008 14.8.
*EN 54-24: Loudspeaker for voice alarm systems for fire detection and fire alarm systems.
FEATURES
• Stainless steel brackets and hardware and powder coated
horn ensure superb weatherproofing and corrosion resistance
• Shock-resistant aluminium oval horn
• Input impedance selector with rotary switch
• Unobtrusive off-white colour (RAL 9010) helps match surroundings.
• IP65 standard complied for dust tight and jet-water proof rating
• EN 54-24 and ISO 7230-24 certified
(Certificate No.: 0359-CPD-0109)
• In compliance with BS 5839-8: 2008 14.8
• Ideally suited for voice alarm system applications
