6.7 Connecting Miscellaneous Devices

The KUS MBU provides connections for an external music source, external page port, relay
contact, and alarm detection input monitor. The EKSU EMBU provides additional connections
for a second relay contact output and alarm detection input. In both cases, an RJ45 jack is
used to terminate the interfaces as shown in figure 6.7-1 below and the wiring charts.
External Music Source
When a call is placed on hold, MOH (Music on Hold) is presented to the caller. MOH can
be provided from an internal source or from an external audio source connected to the
MOH connector.
External Paging Port wiring
The Page connector allows paging audio to be sent to External Paging equipment. The
system will deliver audio as a 0-dBm signal into a 600-ohm load.
Relay Contact Output
The Miscellaneous connector includes connection to an External Control Contact. The
External Control Contact activates as a Loud Bell, a Door Open controller, or control for
External paging equipment when External Paging is access.
Alarm Sensor and Relay Wiring
The Miscellaneous connector provides access to the Alarm Sensor circuitry. The sensor
can be used to monitor an external alarm or doorbell contact.
To wire the miscellaneous connections, referring to figure 6.7-1 and the Modular jack
termination charts below,
1. Wire the Miscellaneous terminations to the appropriate termination point for the
external devices.
2. Tag the wiring for future maintenance.
