Two SP4-RMX modules can be ganged together when connecting them to an SP40/2 panel. This provides a maximum of six remote
microphones providing “All Call” for the entire system. One SP4-RMX can be connected to each audio booster providing three non-
alarm/general page remote microphones for that audio booster audio output. Each SP4-RMX provides a line level, 600 Ohm auxiliary
audio input.
There are two configurations for the Priority levels of the remote microphones can be set. One configuration sets the priorities as:
RM1, priority 1; RM2, priority 2; and RM3, priority 3. For instance, if RM3 is broadcasting, RM1 or RM2 can override RM3. The
other configuration allows the first remote microphone to broadcast to have the top priority until it completes its message. The remote
microphones operate on a first in – first out basis.
