LSC22-002N Loudspeaker Controller ASM-LSC22 Installation and Operation Manual Supplement
This supplement contains installation and operation information that is unique to the LSC22-002N Loudspeaker Controller. Installation and operation information common to the LSC22-001 base unit can be found in the ASM-LSC22 Installation and Operation Manual.

Description

The LSC22-002N Loudspeaker Controller is identical to the LSC22-001 with the following exceptions:

• Changes to the faceplate text can be found by comparing Figure 1 to Figure 2.
  

• The LSC22-002N has NVIS Green A compliant backlighting.

• The INT PA speaker level output is replaced by a mic level CABIN PA MIC output.

•  A new discrete output EXT/INT outputs a ground when front panel EXT PA is selected.

•  Power switch function on the front panel is removed. When power is applied to the LSC22-002N, the unit is powered on without any other action.

Installation

For installation information and drawings, see ASM-LSC22 Section 2.0. Select the appropriate revision of the drawing for the serial number of the unit. The drawings specific to this derivative are listed below and can be found at the end of this supplement.

Section 3.0 Operation

• Ignore any reference/functions to AUX audio input from the rear dmin connector.

• The CHIME input is only and always available on the INT PA audio output. It is not dependant on the front panel EXT PA/INT PA switch position or VOL control. It is summed with the appropriate inputs when the EXT PA/INT PA Switch is set to INT PA:

• When the EXT PA/INT PA switch is set to the EXT PA position, a ground is output on EXT/INT.

• There is no front panel On/Off control in the detent position, unit is always on with power applied. However, the physical detent position on the control still exists.
  Audio output remains at a minimum whether the volume knob is set ccw to the detent or fully ccw into the detent position.

• Message 3 and Siren audio programming now require the power input to the LSC22 be removed and is not dependent on the VOL knob position.

• The CHIME input is not affected by the -3dB Select discrete input..
