A. Description.
The Federal Signal Model AM30T is a conservatively rated 30-watt constant-directivity
paging projector for use in any public address or paging application.
The driver employs a rugged phenolic diaphragm, 1.5-inch diameter voice coil, and "rim
centered" ferrite magnet structure for long life and durability under extreme
operating conditions.
The AM30T includes connections for 25V, 70V and 100V distributed systems and a
screwdriver operated power tap select switch.
A nominal 60° horizontal by 40° vertical coverage pattern together with a low-frequency
cutoff of 350Hz provides excellent articulation in demanding applications.
The AM30T is molded from high-impact ultraviolet inhibiting ASA (acrylic styrene
acrylonitrile). A positive lock super tough nylon swivel base provides maximum mounting flex-
ibility and ease of installation.
Ideal for both indoor and outdoor applications, these horns are well suited for any installation
requiring rugged, reliable performance.
