9.5. Junction Panel JP-0410 Connection
9.5.1. Connecting the Junction Panel's rear-mounted terminal block
1. 24V IN/OUT terminals
• The power capacity of the JP-0410's
built-in power supply is 2 A. Use the 24V
IN/OUT terminals when the power
capacity is insufficient because of an
increase in the number of zones or
remote controls. (Refer to p. 35.)
• The junction panel is shorted between
IN and OUT terminals using a jumper
wire at the factory. Remove this jumper
and connect an expansion power supply
when using the expansion power
supply. (Refer to the figure on the right.)
2. EMG (Emergency) 24V terminal
• 24 VDC is output when emergency broadcast is made. (Maximum usable current: 100 mA.)
• Used to control external equipment.
3. EMG (Emergency) DS, GEN (General) DS, BATTERY FAULT/ CHECK terminals
• Connect to the DS-029B's rear-mounted terminal block.
4. TIMER 2 terminal
• Connects to the music playing machine's BUSY terminal activated by timer.
• Preset broadcast zones are automatically selected at the designated time, and the time signal (such as
Westminster Chime) is provided to the preset zones.
5. CHIME OUT terminal
• Connect this terminal to play the music playing machine's 4-tone chime without installing a chime device in
the pre-amplifier.
• Pressing the chime button on the main rack, general remote control unit or emergency remote control unit
currently making broadcast outputs an activation signal from this terminal.
6. Power amplifier panel connection terminals
• Connect to the power amplifier panel's speaker output terminals. There are two pairs of terminals (C1-H1
and C2-H2), and the relationship of each terminal to output speaker line is as shown below.
C1/H1: Speaker lines 1-5
C2/H2: Speaker lines 6-10
• These terminals are shorted with a jumper wire between C1 and C2 and between H1 and H2 at the factory.
Remove the jumper wire and connect these terminals to individual power amplifier panels when avoiding the
parallel operation of power amplifier panels or when making different broadcasts to each of five-zone
groups. Note that if the jumper wire has been removed, the output of the second power amplifier panel and
its subsequent panels cannot be monitored without the Monitor Panel MP-011.
