2 | SP4‑RMX Remote Microphone Expansion Module
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.
