Electrical ratings:
5 VDC, 160mA
For battery calculations, the
NIM-1R draws 70mA from 24 VDC.
NIM-1R Network
Up to 32 MXL Systems can be con-
nected in the network with an NIM-1R
installed in each MXL System. For the
highest level of fault protection, install
the NIM-1R in the enclosure with the
MMB-1/-2, although this is not neces-
sary. When connecting more than 32
MXL Systems, a REP-1/D2300CP
repeater is required. Refer to the
REP-1 Installation Instructions

Installation Instructions
, P/N 315-
092882, for the wiring diagram.
The network can be installed as either
Style 4 or Style 7. Style 7 is required
in Canada.
Each NIM-1R is shipped with two 120
ohm EOLRs—only two are required
for each network pair. Install an EOLR
at the ends of each network pair. Do
not install an EOLR at each NIM-1R.
(For a simple rule of thumb, an EOLR
must be installed where only a single
wire lands on a screw terminal.)
Do not T-tap the network wiring. If
T-tapping is required, use the REP-1/
D2300CP repeater. Refer to the
NOTES
1. Power limited to
NFPA 70 per NEC 760.
2. Minimum wire size:
18 AWG.
3. Maximum resistance:
80 ohms per pair.
4. Use twisted pair or
shielded twisted pair.
5. Terminate the shield
ONLY at MXL panel 1.
6. Maximum voltage:
8V P-P.
7. Maximum current:
150mA.
8. For Style 4 omit all
Network Pair B
connections.
9. Do not use terminals
12 - 16 if NCC is not
connected.
