MODELS: ST-H15-B & ST-H30

GENERAL:

Horn speakers should be used in large and/or noisy locations. They are weatherproof and may be used indoors or outdoors. The
setting of the variable transformer tap selector switch should be set to provide a sound output of at least 6dB for paging, and 3dB for
background music above the background noise everywhere in the paging zone. However, the horn speaker's volume should not be set
so high as to cause discomfort to those closest to the horn. In some cases, use of multiple horns set at lower volume provide better
sound coverage, than one horn set at full volume. Horns should be mounted at least 15 feet above the floor, and angled downward.
