2.2.8. Play Mode:
Standard Operation:
A momentary contact closure causes the device to play one sequence of the
message corresponding to that input. A sequence being the number of plays selected by the dip
switches and the selected delay time which separates them. If a contact is maintained active, the
system will continuously play that message repeatedly until the input is released at which time the
system will finish the current playback sequence and then stop.
If multiple inputs are held active the system will play one sequence of the first message and then
cycle through any other active messages sequentially based on the order which they were input.
The message corresponding to the lower input number will have priority should multiple inputs be
activated at exactly the same time.
If a momentary contact closure is provided while a message is playing and it is released prior to the
ending of the message play, it will be ignored.
The system will only queue messages in this mode when inputs are activated simultaneously. If
eight simultaneous inputs are momentarily provided to the system, the device will play all eight
message sequences and then stop.
Play one sequence per closure:
If an activation input is maintained, the system will only play the
message sequence one time. The M3 will wait for the input to go inactive for a preset amount of
time before it will recognize that input for subsequent message activation. Other play activations
will be serviced normally even with another input held active indefinitely.
This mode supports message queuing. Message queuing allows the user to input multiple,
momentary activation's to the M3, causing each of the messages to be played in the order they
were received. The queue length will be 16 messages maximum, including the message which is
playing. Any activation issued once the queue is filled will be ignored.
A stop command will stop the message which is currently playing, and when released, the next
message in queue will begin playing.
If multiple inputs are held active and maintained, the system will play each of them and then stop.
Play while active:
The M3 will be activated upon reception of a maintained input control signal.
The message will continue to play for the duration which the control signal is held active. If the input
signal is removed prior to the end of the message sequence, the system will immediately abort the
playback sequence.
If the input is not removed during the delay time after the last message play in the sequence,
another sequence will be initiated. If the input is removed prior to the end of the delay time the
message will not be replayed.
If multiple inputs are maintained active while in this mode, the system will only play the lower
numbered message and then repeat.
Re-Trigger:
This mode allows playing messages to be interrupted by another incoming message,
or another activation of the same message. If a message is currently playing and another message
activation is received, the currently playing message will be stopped and the new message will be
played.
A maintained message activation will only play the sequence one time and then stop. If multiple
inputs are activated at exactly the same time, only the lower numbered message will be played.
