Switches
4.1.1 Manual Evacuate/Message Override
Manual Evacuate/Message Override is a two position switch used for
manually generating programmed evacuation tones/messages or for
paging. It is visible through the window of the closed backbox door.
The door must be unlocked and opened for access to the switch.
Switch activation will cause the following:
•
Placing the switch in the UP or Manual Evacuate latching
position will generate the programmed evacuation tones/mes-
sages out of the amplifiers. Returning the switch to the nor-
mal position will stop the audio output.
•
Holding the switch in the Down or Message Override non-
latching position interrupts the generated audio output from
the amplifiers if the unit is in alarm. This allows use of the
microphone for emergency paging. It is not necessary to hold
the switch down when paging while the system is in the
standby (nonalarm) state. Releasing the switch while in
alarm, returns the VECP to generating audio evacuation tone(s)/messages(s).
4.1.2 REC - Record Push Button
The switch labeled TROUBLE SILENCE is also used for recording a customized message. The switch is not labeled
as 'record' to help prevent unauthorized recording.
Recording Instructions

nal microphone or via the RCA Jack.

5.
of the 'Trouble Silence' switch which is labeled 'REC' will begin to flash at a one second rate. Recording of
the message should begin as soon as the LED starts to flash. After initially flashing for five seconds, the
'REC' LED will be on steady throughout the record operation and then begin flashing again to signal that
there are five seconds of record time remaining. Note that the system Trouble LED will be on while recording
but the trouble sounder will remain off. The trouble relay will turn on. The system will not respond to the
CMD inputs or Manual Evacuate switch while recording.
At the end of recording, the 'Trouble Silence' key must be pressed again to signal the end of the recorded mes-

sage. Avoid long pauses at the end of the message by promptly pressing the 'Trouble Silence' key when the
voice message input has stopped. Note that it is not necessary to fill the entire 60 or 30 second record time.
