DESCRIPTION:
Wheelock Paging Speakers are ready to be installed assemblies consisting of a loudspeaker, round white grille, and a combination
25V/70V line matching transformer. ST-B4 includes a plastic surface mount housing. ST-C8, ST-C8V, ST-C8M and ST-C8MV
include a round flush grille. ST-C8V and ST-C8MV include a recessed volume control. ST-C8 refers to all models for specification
and installation purposes. The volume attenuation will reduce output by 20dB.
The ST-C8 models are 8" ceiling mount speakers, used primarily in office areas, hallways and other low to medium noise level areas.
The ST-B4 is a 4" surface wall mount speaker used in the same areas, when it is not convenient to mount ceiling speakers.
The areas ambient noise level will determine the speaker power (volume) tap chosen for a specific installation. Table 1 shows typical
noise levels in various locations.
