Bosch SP4RMX Specfications

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.

Mounting Considerations

The SP4‑RMX is mounted in its own enclosure and is
designed for indoor use only. To meet NFPA and UL
requirements for the interconnection of fire alarm control
equipment, the module must be mounted in the same room
as and be within 20 ft (6 m) of the SP40/2 or SP40S control
panel.

Wiring Considerations
Between SP40/2 or SP40S control panel and SP4-RMX
modules

All wiring between the module and the control panel must
be within conduit and no longer than 20 ft (6 m). Use
14 AWG (1.9 mm) to 22 AWG (0.7 mm) shielded wire with
one end of the shield connected at either the SP40/2 or
SP40S control panel or at the SP4‑RMX module.

Between each SPRM microphone and the SP4-RMX
module

Use 14 AWG (1.9 mm) to 22 AWG (0.7 mm) shielded wire
with one end of the shield connected at the SP4‑RMX
module. The maximum wire length is 2000 ft (609 m) and
the maximum capacitance for the total wire run is 0.05 μF.
