3 PRS-CSKPM Call
Station Keypad Module
3.1 Introduction
The PRS-CSKPM Call Station Keypad Module can be
used to add keys and indicators to a custom-made call
station based on the PRS-CSM (see section 1) or the
PRS-SCRM (see section 2). The module has a metal
housing for easy mounting and stacking in cabinets, and
screw connectors for easy interconnection to switches
and indicators. See figure 3.1 for a block diagram of the
call station keypad module.
For each key input, two LEDs are available as status
indicators (LED1 and LED2).
