Description
The DVS-511 is an Amplified-Speaker for use in industrial and Fire
Alarm applications. When mounted in a cluster of 4, full 360-
degree coverage of full audio sound can be accomplished.
The DVS-511-4 Cluster is powered by polarity protected 24-VDC
and accepts a 25-VRMS (70-VRMS optional) Audio input.
The enclosure can be fastened to, or hung from, the ceiling using
conduit or chains, providing a clear path for both audio and visual
to the protected area. Coverage area depends greatly upon local
conditions, but from 20,000 to over 100,000 square feet per cluster
can be realized

Operation
The DVS-511-4 is typically used to provide a high audio level in a
wide area, without the need of running high power audio lines a
great distance.
By using one 6-amp NAC Expander type power supply per cluster,
a supervised single service drop can power 4 speakers and the
visual strobe, for a cost effective installation. This power supply
can be switched on to provide the signals as needed, but draw no
current during standby conditions.
Adding the 518-cd or 760-cd Super-Strobe, or a UL Fire-listed
strobe, a visual is added to the same cluster, creating a single source
for emergency condition communications.
Access for all wiring is via the hinged cover, allowing it and the
strobe to swing out of the way for easy wiring, even after installed.
