f) Paging Interface (optional)
The WPS-2900 may be equipped with an optional module that allows the user to broadcast
siren tones, digital voice messages or public address through existing in-plant public address
systems.
The audio output of the Paging Interface Module is a 600 ohm, transformer coupled signal.
This output interfaces with most industry standard paging systems. A level adjustment
potentiometer allows the user to set the siren output to a desirable level, through the public
address system.
The Paging Interface Module also has an output relay that makes a 1 amp rated, contact
closure whenever the siren audio is active. This is typically used to perform the in-plant PA
microphone “Push-To-Talk” function.
