General Description
Introduction
This manual describes the features, specifications, and installation of the Directional
Speaker Array (DSA). See the UltraVoice Electronic Siren Controller Manual for operating
instructions.
The DSA is a flexible and adaptable high-powered speaker array. It can be configured
in many ways to customize your site’s needs. Let Federal Signal design your DSA
configuration. Contact Federal Signal through pre-sales or contact your local sales
representative.
The DSA is a flexible family of high-powered speakers capable of providing audible
signals (tone or voice) over a large area to satisfy varying signaling needs in multiple
directions. A typical installation consists of between one and four arrays designed to be
powered by a Federal Signal UltraVoice Controller. A highly efficient design enables the
speakers to produce a high sound level while making moderate demands on the power
source. Each array can contain between two and six individual speakers. (Figure 1 shows
two DSA4s with a DSAMK4 bracket.)

DSA speakers are comprised of fiberglass projectors and aluminum housings and
stainless steel mounting brackets that include hardware for mounting the bracket to the
speaker. Each speaker provides 100 watts of signaling power.
Each DSA2, DSA4, and DSA6 speaker array includes one DSAMK1 bracket. A DSA
speaker requires two brackets for proper mounting. When mounting DSAs to poles,
several brackets can be attached. These brackets provide secure mounting for a variety
of applications. If mounting to a pole, see “Table 6 Bracket Options” on page 13.
