Overview
Standard Features
The 5520D Series Horn/Siren Combination is an extremely high
decibel, high-performance signalling appliance intended for fire
alarm and life safety applications. They are perfect for indoor or
outdoor applications including schools, factories, lumber yards and
even boats. They can be used where standard bells or horns are
not satisfactory, particularly in areas of high noise level. The unit will
function as a Horn or Siren with just the flick of a switch.
• 24Vdc
• Solid-state
• Extremely high dB
• Suitable for coded signals
• Swivel/adjustable mounting
• Outdoor/weatherproof option
The universal mounting plate will install directly over any standard
North-American 1-gang opening, standard octagon box, or 4 inch
square electrical box. The megaphone may be swivelled through
180° horizontally and 90° vertically. All wiring is made to
colour-coded wire leads attached to a quick-disconnect plug.
When complete the device just plugs-in and is locked to the
mounting plate with a set screw.
Installation and Mounting
Once mounted, the horn/siren switch is tamperproof. The horn is
suitable for “coded” applications; the siren is not. The complete unit
is finished with a metallic gray enamel.
