An external ringer (either audible ringing or a bell, buzzer, etc ) can be

used to alert users when Universal Night Answer (UNA) calls come in

The CPC-M supplies a relay that activates when UNA calls are present

This relay can be used to activate an external device (bell buzzer, etc )

Alternatively, this relay can be used to activate the audio output of an

amplifier when a UNA call is present.

The CPC-S does not have a UNA relay or separate ER audio aoutput. If

UNA is used with a CPC-S, the UNA external ringer audio output must be

directed out at the EPA connector It is recommended that the EPA output

be connected to a voice-activated amplifier to eliminate background

"white' noise

The contact rating for the "Cl' (Common 1) and "Ml"(Make 1) terminals

is 30V DC, 1 amp (maximum) (CPC-M only)
