5. EXT CHIME/ FIRE COM
EXT CHIME: Terminal to operate the CHIME2 using an external contact.
FIRE COM: FIRE SENSOR common ground input terminal.
6. 24V – A/24V – B TERMINAL
Terminal used when 4-wire Attenuator is used. SPEAKER OUTPUT terminals (+, –) and 24V – A(or 24V – B),
are used to connect COM port.
7. COM TERMINAL
24V – A/24V – B’s GND terminal.
8. CONTROL OUT TERMINAL
- EM (Emergency)
The terminal is used to control external devices when the broadcasting mode is changed to emergency
broadcast (EM/Fire/Pri), and the contact is closed regardless of speaker zone settings.
- PD (Power Distributor)
It is used to control power distributor remotely. By connecting to the remote control terminal of the PD,
contact output is made when there is a signal output in any speaker zone, regardless of broadcasting
mode (EM/Normal)
9. OUTPUT VOLTAGE SELECT SWITCH
100V / 70V output select switch.
※
NOTE : Before using the switch, make sure the speaker impedance is proper. (10.3 Please refer to the
nominal output impedance information).
10. SPEAKER OUTPUT CONNECT TERMINAL
The speaker output terminals of each ZONE (1~24). General Broadcast (2wire), Emergency Broadcast
(3wire), ATTENUATOR (4wire) are possible. Terminals are set from left, +, –, and E.
1) Speaker Output Signal
- Normal Broadcast: Connection to (+, –) will produce output.
- EM / FIRE Broadcast: Connection to (+, –)/(E, –) will produce EM broadcast output.
2) Speaker Connections
- When connecting the speakers, disconnect the power cord from the wall outlet. Depending on the type
of speakers in use, select the appropriate speaker terminals on rear panel.
3) Rated Power Output and Impedance
