10. PAGING WHILE POWER IS OFF
The 9000 Series amplifiers are designed to initiate paging by way of the ZP-001T module or activate the
Event*
1 even while the power is OFF* 2 .
The unit operates as follows when the power is switched OFF:
• Events* 1 by control input (including the C-001T module) can be activated, but those using the VOX (Voice
Operated Exchange) function cannot be activated.
• The unit returns to Power-OFF state after Event or paging completion.
• Broadcasts can be initiated from the ZP-001T regardless of whether the operation mode is set to Ring Signal
or Paging Port.
• Broadcasts cannot be performed for 2 seconds during which the Event is activated and the power amplifier
begins to operate.
• When the power is switched OFF while an Event* 1 is being activated by way of the control input with the
power ON, even if the Event* 1 is still left activated, the above-mentioned Events* 1 or paging calls from the ZP-
001T will have a priority regardless of priority level.
Controls to be performed during power-OFF
The power switch located on the amplifier front panel is a soft-switch, and not a mechanical switch
to be used to turn on or off the power supply's primary side. Therefore, the internal microcomputer
is still operating even if the power switch is set to OFF.
The following controls can be performed when the power is OFF.
• Remote power control by control input
Power can be switched on and off using the external contact.
• Event* 1 activation by control input
Turns on the unit's power and activates the assigned Event (Trigger-set Event having the input
with Priority 1 – 7) using the external contact. The unit returns to power-OFF state after Event
operation completion.
• Paging by the ZP-001T
Turns on the unit's power. The unit returns to power-OFF state after paging completion.
* 1 The Event activation applies in the normal matrix operation. Take it as "Input channel ON" in the 1-channel
or 2-channel output operation.
* 2 The state that the front panel-mounted power switch is set to OFF position, and the power is still supplied to
the unit from the AC inlet.
