Wiring Guidelines:
Use shielded twisted pair wire for all audio input and output wiring. Follow national and local regulations for conduit use.
The shield of each cable should be connected only at one end. Each shield of each cable that connects to the SP4-RMX is to connect
to the grounding terminal provided near the right edge of the chassis (see Figure 2).
CAUTION:
All SP4-RMX wiring should be routed away from any high voltage or high current lines (such as AC or DC power
lines, audio power lines, and motor or relay actuation lines) and should be installed in separate conduit from high voltage or high
current lines.
The National Electrical Code defines two types of circuits for protective signaling systems: power limited circuits and non-power
limited circuits. All SP4-RMX circuits have been designed as power limited circuits. Do not run power limited and non-power
limited in the same conduit.
CAUTION:
The National Electric Code limits the maximum number of conductors that can be installed in conduit and wiring
boxes depending on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used
complies with the latest NEC requirements for power limited circuits.
Wiring Specifications:
Between SP40/2 (or Audio Booster) and SP4-RMX
Cable Size: 14 - 22 AWG Shielded. One end of the shield must be connected at the SafePath4 panel or SP4-
RMX enclosure.
Maximum Length:
20 Feet
Restrictions:
All wiring between SP40/2 (or Audio Booster) and SP4-RMX must be run in conduit and within
the same room.
Between each SPRM and SP4-RMX
Cable Size: 14 - 22 AWG Shielded. The shield must be connected only at the SP4-RMX enclosure.
Maximum Length:
2000 Feet
Maximum Capacitance: 05uF/Total Run (50pF/foot for 1000 FT.)
Mounting:
The SP4-RMX shall be mounted in a location within the environmental limits specified in the latest UL Standard for indoor control
panels. It shall not be located in a hazardous location. Refer to the "Technical Specifications'' section.
CAUTION:
In order to comply with the latest NFPA and UL requirements for interconnection of fire alarm control equipment,
the SP4-RMX unit must be located in the same room as, and within 20 feet of the SAFEPATH4 Panel it is connected to.
Refer to Figure 2 for SP4-RMX mounting hole layout. Drill mounting holes for appropriate screws and anchors to ensure secure
mounting to the type of surface at the selected location. Keep out dust and dirt during installation. Dust and dirt can interfere with
the operation and reduce the life of the equipment.
Remove the outer cover and mount at the selected location.
Use care to avoid damage to the PC board during installation
. Do not
apply excessive pressure to the PC board or its components; including field wiring terminals and connectors or damage may occur.
