NOTES:
1. 18 AWG minimum.
2. 80 ohms maximum per pair.
3. Use shielded twisted pair.
4. Terminate the shield at the NIM-1W enclosure only.
5. Power limited to NFPA 70 per NEC 760.
6. Maximum voltage 8V peak to peak.
7. Maximum current 150mA.
8. Refer to Wiring Specification for MXL, MXL-IQ and
MXLV Systems, P/N 315-092772 revision 6 or
higher, for additional wiring information.
Foreign System Interface (FSI)
The FSI installs on TB3 or TB4, terminals 1 and 2, of
the MOM-4/2 depending on where the NIM-1W is
installed, as shown in Figure 5. Use one of the EOLRs
provided with the NIM-1W on terminals 1 and 2. This
properly terminates the FSI. Use the second EOLR on
terminals 3 and 4.
Never use terminals 3 and 4 to
connect to the FSI.
Refer to Figure 5 for the polarity
of the FSI driver.
If multiple FSI connections are required, up to four
NIM-1Ws may be installed in an individual MXL
System. In networked systems each MXL can support
up to four FSI ports.
For networked systems, each FSI port must be con-
figured as either local or global in the CSG-M. Local
FSI ports display information only on the MXL System
to which they are connected. Global FSI ports display
all events in all MXL Systems. Refer to the
CSG-M
Manual,
P/N 315-090381, for further information.
Connection via NIM-1W RS-485 Interface
NIM-W RS485 FSI connection should be wired Style 4
only. The recommended Serial Baud Rate when using
NIM-1W RS485 FSI is 19200 bpm. P6 jumper position
on the NIM-1W should be set for RS-485 configura-
tion as shown in Figure 1. Refer to Figure 5 for wiring
instructions.
Connection via NIM-1W/NIM-1M Modem
NIM-1W/NIM-1M modem FSI connection should be
wired Style 4 only. P6 jumper position on the NIM-1W
should be set for Modem configuration as shown in
Figure 2. The recommended Serial Baud Rate when
using NIM-1W/NIM-1M Modem FSI is 19200 bpm.
Refer to Figure 16 for wiring instructions.
Air Sampling Interface
AnaLASER Interface
The AnaLASER Air Sampling interface connects to the
MOM-4/2, TB3 or TB4, terminals 1 and 2, depending
on where the NIM-1W is installed (Refer to Figure 7).
Up to 31 Air Sampling detectors can be connected to
a single NIM-1W.
The ACC-1 requires an RS-485 to RS-232 converter
which mounts in the back of the ACC-1 enclosure. The
converter model number is AIC-4Z. The AIC-4Z
supports from one to four AnaLASER detectors. Refer
to the
AIC-4Z Installation Instructions,
P/N 315-
093792, for the mounting and configuration of the
converter and the ACC-1s.
Complete wiring of the converter as shown in Figure 7
before installing the ACC-1 in the enclosure.
• Place the end-of-line resistors in the locations
specified in Figure 7.
• Install the cable P/N IC-12 between the converter
and the ACC-1.
• Refer to the
AnaLASER Air Sampling Smoke
Detection Manual,
P/N 315-092893, for connec-
tion to the AnaLASER detector and power supply,
as well as mechanical mounting of the ACC-1.
GROUND FAULT DETECTED AT <70K OHMS FOR TERMINALS 1-4.
