INSTALLATION INSTRUCTIONS FOR
SUPERVISED CEILING SPEAKER WITH AMPLIFIER
Valcom Supervised Ceiling Speaker, VLSCS, is self-amplified and capable of reproducing voice paging as well as
background music. The VLSCS features a removable volume control knob or volume can be adjusted by a
screwdriver through the center hole on the grille. Input and output connections on the amplifier allow easy chaining
of speakers. The unit requires -24 Vdc, 50 mA (1 power unit).
NOTE: Do not connect this speaker directly to
a 25/70/100 volt amplifier as damage to both the
amplifier and speaker may occur. A V-1095
may be used to allow the use of Valcom
self-amplified speakers on 70V speaker lines.
