Specifications

The night ringer normally sounds a simulated ring tone but can be programmed to sound a chime tone. Refer to
System Programming, Section 11 to set up a night ringer zone group or to change to ringer tone.
To physically connect the night ringer wiring:
1. Make sure that power is off.
2. Plug a modular cord into the NIGHT RING (RJ11) jack.
The center conductors of the plug are used for the 90V ring signal (see Figure 5-9). The flanking conductors are used
for contact closure activation. Maximum contact resistance for contact closure activation is 1000 ohms.

RJ11 Connections
Note: The Night Ring feature has priority just above background music. There is a 5-second delay after the night
ring stops before background music is restored (bridges inter-ring pause).
5.7. Over Ride Input
The Over Ride is a non-programmable feature that lets the caller take priority over all paging functions and make a
system-wide page to all speakers. The feature can be activated using a loop start trunk or dedicated telephone.
Provisions are also included to interface with other signaling equipment.
The Over Ride feature includes a quad beep pre-announce tone that can be enabled or inhibited. (The default is
inhibited). See System Programming, Section 11 to enable the tone.
1. Make sure that power is off and all connections completed before proceeding.
2. Plug modular cord into OVER RIDE (RJ-11) jack.
The center two conductors interface directly to a Loop Start Trunk or dedicated phone (see Figure 5-10). When the
trunk becomes active, the PCM goes into Over Ride mode.
Also, see connecting to an External Audio Source, page 53.
