System Layout Considerations
The installer must consider the system layout to assure proper audio delivery to the Electronics Paging
Module.
 For hardwired installations, each paging module requires a balanced 600-ohm, 0 dBm input audio
signal. A contact closure may be required depending on the selected operating mode. Cabling
(telephone cable, cat-5/6, etc.) must be distributed appropriately to attain the necessary audio level
and balance. Audio distribution apparatus may be necessary to accomplish this task.
 For RF installations, each paging module must be located within range of the RF transmitting device.
Operating Modes
The Electronics Paging Modules can operate in two different modes, referred to as Generic and Selective.
The mode of operation determines if the paging module’s speakers will broadcast all audio transmissions
or only “selective” audio transmissions. Each operating mode is described below.
Generic Operation
Generic Mode requires an external control input to activate (wake up) the paging module. Once active,
the unit will broadcast any audio received from the transmitting device. Removal of the activation input
returns the paging module to the inactive (sleep) mode.
 For hardwired installations, the control input activation must be in the form of a voltage–free (dry)
contact closure.
 For RF installations, the control input activation is provided from the “RF carrier detect” control
circuit of the integral radio receiver.
All paging modules are factory programmed for Generic Operation.
