NIM-1R Connections and Ratings
AnaLASER Interface
The AnaLASER interface connects to
the MOM-4/-2, TB3 or TB4, terminals 1
and 2, depending on where the
NIM-1R is installed. Up to 31
AnaLASER detectors can be connected
to a single NIM-1R.
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
before installing the ACC-1 in the
enclosure.
Place the end-of-line resistors in the
locations specified in Figure 4 below.
Install the cable, P/N 500-693801
between the converter and the
ACC-1.
Refer to the AnaLASER Air Sampling
Smoke Detection Manual, P/N 315-
092893, for connection to the
AnaLASER detector and power
supply, as well as mechanical mount-
ing of the ACC-1.
