and vertical dispersion at -6 dB below the on-axis reference at 2k Hz shall be SC-610/T: 70° H x
100° V; SC-615/T: 70° H x 90° V; SC-630/T: 55° H x 70° V; SC-650: 55° H x 45° V. When used
as a microphone, sensitivity referenced to 1k Hz, where 0 dB = 1 mW/10 dynes / cm2 shall be
SC-610/T:-24 dB; SC-615/T: -22 dB; SC-630/T: -20 dB. The paging horn shall comply with the
IEC IP-65 standard for dust and moisture resistance and operate within a temperature range from
-4° F to 131° F (-20° C to +55° C). The material / finish shall be horn flare: aluminum, off-white,
powder coating, reflector horn and rear cover: ABS resin, off-white. All mounting hardware,
including screws and bolts, shall be stainless steel. The paging horn shall include an integral
speaker cable, insulated polyvinyl chloride type, with strain-relief, 0.24" (6 mm) diameter and 24"
(600 mm) length.
