4.6 Volume Control Remote Override
Volume override relay contacts shall be provided for each zone separately for overriding local
loudspeaker volume controls. The VCT25R Volume Control Remote supports (2-wire, 3-wire and dual
amplifier sound restoration i.e. standard 24V). Upon a call or an activated trigger input, these
contacts shall be activated for the appropriate 8 zones of IDA8 controller.
VCT25R is an volume control device (25W/80W) with 10-step attenuation separately. Volume
restoration levels can be pre-set, decreasing in 3dB steps (either -3dB or -6dB) to an OFF (0dB) with
non-stop selector giving a smooth variation in output level. Providing volume control with a wide
frequency response of 40Hz - 20 kHz. The paging levels can be restored and be adjusted to suit the
environment like a noisy warehouse or a quiet office.
