MASTER STATION'S FUNCTIONS AND OPERATION
[External timer-initiated event settings]
• "Time Signal" broadcasts can be triggered by make contact from an external timer connected to the N-8000AF
Audio Interface's contact input.
• The external timer-initiated event is comprised of the following contents for each contact input (1 − 8): Paging
zones (up to 10 zones selected from 192), sound source numbers (0 − 9) and external equipment control (ON
or OFF).
5.3.2. Automatic time signal activation
[Operation]
• Audible time signal can be broadcast in synchronization with preprogrammed events.
• Schedules to be activated must be set in advance.
Time signal is broadcast over preset paging zones when the event activation time for each preset schedule
is reached.
• Only one (1) N-8000AF in the system can be set to transmit the time signal.
• The time signal sound source can be either the N-8000AF's internal sound source or an external sound
source connected to the N-8000AF.
• Contact output terminals (any of contact outputs 5 − 8, including those of another N-8000AF, N-8000MI, or
N-8000DI) can be closed to operate a bell or other external equipment in synchronization with Time Signal
Activation.
• New events activated during Time Signal operation are ignored.
• Time Signal operation is terminated when the preset sound source operation time elapses.
• The function to limit the paging time does not operate.
• If "Silent" is selected and external equipment control is set to OFF, nothing is operated.
[Activation]
The following two methods can be used to automatically trigger the time signal.
(1) Activation by Internal Timer
• Time signal begins operation in synchronization with the preprogrammed event activation schedule.
• Time is managed by the N-8000AF's internal timer.
• Schedules to be activated can be changed through operation of any master station.
(2) Activation by External Timer
• The Time Signal begins operation when the N-8000AF receives make contact from the connected external
timer.
• Connect the external timer to the N-8000AF's contact inputs (1 − 8).
• The Time Signal operates according to the external timer-initiated events preprogrammed for the individual
contact inputs.
• The Time Signal is activated by make contact from the external timer. However, opening the contact will not
terminate Time Signal operation.
