25. Timer Input Terminal
Connect audio and control signals from timer-
operated equipment to this terminal. Input
signals to this terminal are broadcast with the
highest priority when the control terminals are
closed.
Audio: 0 dBV, 600 Ω, unbalanced
Control: Open voltage: 26 V DC; short-circuit
current: under 2 mA
4P terminal block
26. EV Audio Input Terminal
Used to connect the FS-7000EV. This input can
be used only while an emergency broadcast is
being made. (0 dBV, 600 Ω, unbalanced, 2P
terminal block)
27. Output Mode Selector Switch
Sets the audio output to "1-CH" (1-channel) or
"2-CH" (2-channel) broadcasts.
(Default: 2-channel broadcast)
28. Functional Earth Terminal
Connect this terminal to the functional earth
terminal of external equipment if excessive noise
is generated when the FS-7000CP is connected
to the external equipment. This could reduce
noise.
Note: This terminal is not for protective earth.
29. All-Zone Call Mode Selector Switch
Sets the mode of broadcast to be initiated with
the All-Zone Call button (13). When the FS-
7000AT has been connected to the system, if
this switch is set to "URGE" (general urgency)
and an all-zone call is made, a 24 V DC for
controlling attenuators is output, permitting the
call to bypass the attenuator. (Default: "NORM")
30. BGM Output Terminal
Signals from the BGM Inputs 1 – 4 (16 and 18)
are mixed and output. Connect this terminal to
the power amplifier for BGM broadcast. (0 dBV,
600 Ω, balanced, 3P terminal block)
31. Priority Output Terminal
When the Output Mode Selector Switch (27)
is set to 2-channel broadcast:
Outputs signals other than those from the BGM
Inputs 1 – 4 (16 and 18). Connect this terminal to
the power amplifier intended for priority
broadcast.
When the Output Mode Selector Switch (27)
is set to 1-channel broadcast:
Outputs signals from all audio inputs. Signals
output from sources other than BGM Inputs 1 – 4
causes these 4 BGM input signals to atttenuate.
Connect this terminal to the power amplifier. (0
dBV, 600 Ω, balanced, 3P terminal block)
32. Automatic Fire Alarm System Input Terminal
Connect this terminal to the floor identifier signal
transmitted from the automatic fire alarm system.
The identifier signal automatically selects zones
and broadcasts audio alarms to such zones.
(Open voltage: 26 V DC; short-circuit current:
under 5 mA; 12P terminal block; 10 zones +
COM + COM)
Note
This terminal is not connected when the FS-
7000EV is not used.
33. EV Control Terminal
Connect the FS-7000EV to this terminal.
34. RF Zone Control Terminal
Use this terminal to connect the FS-7000RF.
Data regarding broadcast zones transmitted from
the FS-7000RF is input to this terminal.
35. RF Control Terminal
Use this terminal to connect the FS-7000RF.
36. CP Control Terminal
Use this terminal to connect the FS-7010CP. All
of the FS-7010CP units that are mounted in the
system must be connected to this terminal.
37. JP Control Terminal
Connect this terminal to the FS-7000JP when the
FS-7000GM is not connected to the system.
Note
This terminal is not used when the FS-7000GM
is connected to the FS-7000CP.
38. JP/GM Control Terminal
Connect this terminal to the FS-7000JP or FS-
7000GM.
When the FS-7000GM is not connected to the
FS-7000CP:
Connect this terminal to the FS-7000JP in order
to control speaker line ON/OFF operations.
When the FS-7000GM is connected to the FS-
7000CP:
Connect this terminal to the FS-7000GM. The
Zone Selector keys (7) on the front panel
function as group selector keys.
