General Information

The Model 12521-004 Microphone Assembly Replacement Kit is used in the 39x Series RED ALERT™
Emergency Telephones. The kit includes two gasket types, only one of which will be used, depending on

components:

Qty Description

1 Microphone assembly with wiring (See Figure 3.)
1 Microphone shield
1 Microphone gasket (thick) for flush-mount telephone

panel security screws. Field wiring will restrict complete removal of the front panel. Note all field
wiring terminations to unit and disconnect field wiring to allow front panel to be placed on a working
surface.

2. For the wall-mount telephone, remove the PCBA to allow access to the microphone assembly.
