Guidelinesl
An external ringer (either audible ringing or a bell, buzzer, etc ) can be
used to alert users when Universal Night Answer (UNA) calls come inl
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.l
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’ noisel
The contact rating for the “Cl’ (Common 1) and “Ml”(Make 1) terminals
is 30V DC, 1 amp (maximum) (CPC-M only)l
An external ringer device (bell, buzzer, etc ) is not provided with the DBS
824 It must be purchased separately
/Installation of External Ringer Amplifier (CPC-S)
1Connect the EPA connector to the audio in connector of the amplifier
device (Note This output is shared with the paging output)
Installation of External Ringing Device (CPC-M Only)
1Connect the external ringer to the “Cl” and “Ml” terminals on the
Connector Panel (See Figure 5-16 )
Note: Connecting the ringer to the “Cl” and “Ml” terminals provides a
“1 second on/3 seconds off’ ringing pattern Connecting to “Cl” and
“B 
l”(Break 1) terminals provides a “1 second off/3 seconds on” ringing
pattern
2Connect the external ringer to its DC power source

SLTs can be connected to the Power Failure Unit (PFU) (VA-43703) if a power failure occurs, the 
SLTs will automatically receive dial
tone from the central office DBS 824 features and restrictions do not apply
during a power failure when the 
SLTs are connected to the CO through the
PFUlIf a call is in progress through the PFU when the power is restored, the call
will be disconnectedInstallation
1Remove the cover from the Power Failure Unit (PFU)
2Remove the cable punch-out plate (Figure 5-18) to make a opening for
the cables coming into the PFU
To remove the plate, cut the grooves on either side with diagonal cutters
