AMG Voice Message Options
Overview You can install two types of non-memory message chips into an AMG:
VROM (Voice ROM) A nonvolatile memory chip that contains a factory-programmed
message. (An AMG can hold two VROMs: VROM-A and VROM-B.) A VROM
provides one evacuation message (up to 24 seconds long), chosen from many standard
messages available. Refer to Document 15945 for a list of available VROMs.
VRAM-1 (Voice RAM) A nonvolatile memory chip for a field-programmed memory
message. A VRAM-1 provides one field-programmable evacuation message (up to 24
seconds long), programmed from microphone or cassette tape. An AMG can hold up to
two VRAM-1 chips.
Installation To install a VROM or VRAM, follow these steps:
1. Remove battery power, then remove AC power from the control panel.
2. Remove the four screws that hold the AMG dress plate to the component board.
3. Remove the dress plate and disconnect the microphone connector.
4. Install the VROM or VRAM chips in their respective sockets as shown below.
5. Connect the microphone cable and install the AMG dress panel.
When finished installing VROM or VRAM chips, assemble the AMG by following
these instructions in reverse. Figure 39 shows the location of the VROM and VRAM
chips on the AMG-1:
