Selecting AMG Group Functions
Selecting Factory-Programmed Messages (VROM) Operation of tones and
messages available in a voice alarm application depends on the following:
•The type and number of VROM chips installed; and
•The functional groups selected by AMG-1 DIP switch settings.
Note: If a digitally-stored voice
message fails, the AMG-1
automatically switches to the
primary evacuation tone, and
generates a trouble signal.
Installing one or two optional VROMs lets you select a factory-programmed message
by setting rocker switches 6, 7, and 8 on the AMG-1. (Refer to Selecting AMG Tones
and Messages.) For example, Figure 28 on page 27 shows the text of factory-recorded
VROM-101 message in a male voice:
Figure 28 Sample VROM-101 Message
Refer to Document 15945 for a complete description of all VROM Series messages.
Note: A VRAM message can be
up to 24 seconds long. Recording Custom Messages (VRAM option) You can record custom messages
through the AMG-1 microphone or load a message recorded on an audio cassette
recorder. To do so, you must install at least one VRAM chip in U12 (VRAM-A) or U13
(VRAM-B) on the AMG-1 (Figure 29). For example, if the AMG-1 contains a
VRAM-A chip in U12, record a message as follows:
1. If loading a message from a tape recorder, connect the tape recorder to J1 on the
AMG-1. (Figure 29)
2. Set the Voice RAM Enable rocker switch 4 (VRAM-A) or 5 (VRAM-B) on the
AMG DIP Switch (SW2) to the ON position. The AMG-1 starts to record input to
VRAM-A or VRAM-B from a tape recorder or from the AMG-1 microphone.
3. Record a message through the AMG-1 microphone or load a message from a tape
recorder connected to J1.
4. When finished recording or loading the message, set the Voice RAM Enable switch
to the OFF position.
Figure 29 shows the location of connectors and chips on the AMG-1:
