3. Telephone input terminal [TEL IN] (Modular jack)
Interface connector for an analog PABX.
Connect a PABX to this terminal when using the module in the ring
signal mode.
4. Telephone input terminal [TEL IN]
4-pin removable terminal block, 2 pins are used for this input.
This terminal is internally connected in parallel with the telephone input
terminal (modular jack) (3).
Connect a PABX to this terminal when the paging port is used (paging
port mode).
5. Control input terminal [CONTACT IN]
4-pin removable terminal block, 2 pins are used for this input.
Connect the control output from a PABX to this terminal.
6. Control output terminals [CTRL OUT 1 G, 2 G, 3 G, 4 G]
4-pin removable terminal blocks, control output terminals.
Note: These terminals are not used in the Mixer mode.
The ZP-001T module is designed for use with the 9000 Series amplifiers and functions as an interface to
connect the 9000 Series amplifiers to an analog PABX, allowing zone paging to be initiated from the PABX.
Only one ZP-001T module can be used per 9000 Series amplifier.
There are two operation modes: Ring signal and Paging port modes. Select one of the two modes when using
this module.
The operation method differs depending on the set operation mode. (Refer to
p. 30 "Zone Paging." )
[Requirements of the PABX to be connected to the ZP-001T]
• The PABX shall be complaint with TIA/EIA-464-B standard.
• Specifications or conditions required in each of the following modes shall be satisfied:
Note: The ZP-001T may malfunction if the connected PABX does not meet the above requirements.
(A) When using the module in the Paging port mode
• Connection: Line level paging port
• Signaling method: DTMF (The module cannot be operated with dial pulse.)
• Shall provide no-voltage make contact during paging calls.
• Insensitive to whether loop voltage exists or not, and whether polarity of the loop voltage is reversed or
not when a line connection is established.
Note
If the PABX does not meet the above requirements, use the D-001T module and set the trigger to "VOX"
(Voice Operated Exchange) to initiate paging. In this case, the paging output channel cannot be selected,
which differs from the operation by the ZP-001T.
(B) When using the module in the Ring signal mode
• Connection: Analog two-wire extension line, loop start
• Signaling method: DTMF (The module cannot be operated with dial pulse.)
• Reorder tone: 120 IPM (impulses per minute) or less
• Loop voltage: 24 VDC or more* (polarity insensitive)
• Insensitive to whether polarity of the loop voltage is reversed or not at a call from the PABX.*
• Loop voltage supply shall not be cut off from the beginning of a call to the reorder tone out.*
• The state of CPC (Calling Party Controlled) break or "Open Loop Disconnect" shall be reset at the
PABX.*
* Note that there is no need to meet these requirements provided that the ZP-001T's control input terminals
are kept closed. However, noise may be output if the line is physically disconnected during a paging call
because the ZP-001T cannot recognize the line cutoff nor stop output for 30 seconds after paging initiation.
