Fire Alarm Systems | SP4‑RMX Remote Microphone Expansion Module
The Cooper Wheelock SAFEPATH4 SP4‑RMX Remote
Microphone Expansion Module is an outboard expansion
module used with the SP40/2 or SP40S Facilities
Communications Systems. The module expands the
number of optional remote microphones (SPRM) to three.
Each module provides a line level, 600 Ω auxiliary audio
output.
Two SP4‑RMX modules can be used when connected to an
SP40/2 or SP40S control panel. This provides a maximum
of six remote microphones providing All Call for the entire
system.
Functions
Microphone Priorities
There are two configurations for the priority levels of
remote microphones. One configuration sets the priorities
so that remote microphone 1 (RM1) has priority over the
other two (RM2 and RM3) remote microphones and RM2
has priority over RM3. This means that if RM3 is
broadcasting, either RM1 or RM2 can override it. The other
configuration gives top priority to the first microphone to
broadcast so that neither of the other microphones can
broadcast until the first completes its message.
