External Music Source
7.02. The system can use either an internal or external music source. The music source is
selected by the switch located on the MCB. (Refer to Figure 2)
7.03. Connect the music source output leads to the MOHS terminals on the optional
equipment terminal block. If required, connect the external music source controller
leads to the CK1 terminals on the optional equipment terminal block. (Refer to
Figure 14)
Note: DIP switch Element 2 controls the use of a set of dry relay contacts for music
source power control (set to OFF) or loud bell ringer controller (set to ON).
Note: The impedance of the external music source must be less than 32 ohms with a
power level of approximately 100 mW.
Paging Amplifier
7.04. Connect the paging amplifier input leads to the PAGE terminals on the optional
equipment terminal block. This provides paging output for paging zone 8. The
paging output for paging zones 1 - 7 must be connected through station ports
assigned by system programming (Mode 89).
7.05. Amplifier control is provided only when paging zone 8 is activated. To control the
amplifier for paging zone 8, connect the power control leads to the CK2 terminals on
the optional equipment terminal block. In the default state, the relay is open. The
relay closes when a paging call is made to page zone 8. The power control relay is
rated at a maximum of 3 amperes.
Loud Bell Ringer
7.06. Connect the loud bell ringer controller leads to the CK1 terminals on the optional
equipment terminal block. In the default state, the relay is open.
Note: DIP switch Element 2 controls the use of a set of dry relay contacts for music
source power control (set to OFF) or loud bell ringer controller (set to ON).
