MAIN AC POWER

The ICS-52/52T and ICS-92/92T panels can be powered by any

source that can supply between 12 and 16 V RMS AC at 750 mA. The

panels are shipped with a wall-mounted transformer that provides 14 V

RMS AC to the panel. Two types of transformer are available: one

operates on a mains AC input power of 117 V (part number 730166)

and the other operates on a mains AC input power of 220 V (part

number 820049). Make sure to specify the proper transformer when

ordering the panel.

To connect the transformer, route the cord from the transformer’s

secondary to the panel’s “AC Power Input” connector on the rear

panel. This is a 2.1 mm coax connector. When routing the cord make

sure to use the stress relief on the rear panel.

The power input to the panel is internally protected with a 0.9 ampere

“poly fuse,” a self-healing fuse that will recover when the fault is

removed.

ADJUSTMENTS

The following panel parameters are adjustable either internally on the

panel’s main PCB, or externally by selecting options in the

configuration program:

• Headset sidetone (main PCB)

• Panel microphone gain (main PCB)

• Speaker mute (configuration program)

• Page volume level (configuration program)

• Panel-to-matrix card baud rate (configuration program)

All these parameters are set to factory defaults. Most panels should

operate at these default settings; however, some applications may

require readjustment.
