9.3. Activating the Event or Making Paging Calls While Power Is OFF
The 9000 Series amplifiers are designed to initiate paging by way of the ZP-001T module or activate the
Event even while the power is OFF*.
* The state that the front panel-mounted power switch is set to OFF position, while the power is still supplied
to the unit from the AC inlet.
The unit operates as follows when the power is switched OFF:
• Events by control input (including the C-001T module) can be activated, but those using the VOX (Voice-
Operated Switch) 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 Trunk.
• 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 the Event is being activated by way of the control input, the Event
still left activated is overridden by the above-mentioned Event activations or paging calls initiated from the
ZP-001T regardless of priority settings.
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 activation by control input
Turns on the unit's power and activates the assigned Event (set to Trigger) using the external
contact. The unit returns to power-OFF state after Event operation completion.
• Paging by the ZP-001T
Provides the same operation as that which is stated in "Event activation by control input" above.
