MOI-7
Electrical ratings:
Supervisory 5V ± .5V
140mA
Alarm 5V ± .5V
180mA
Electrical connections
The MOI-7 is shipped with one cable as
described below.
5V Power
The MOI-7 receives its 5 volt power on
connector P1. This power can be sent to
other modules requiring 5 volts from P2.
Pin 1 is the positive input; pin 2 the return.
Use the supplied cable, P/N 600-291261.
MXL Network Connection
The MOI-7 can be connected to the
MXL network in three ways.
The first connection is for Style 4. For
Style 4 wiring use only terminals 1 and
2 of TB1; terminals 3 and 4 of TB1 are
not used. In a Style 4 network, make
only Network A connections and ignore
all Network B connections. Do not use
connector P5 in this configuration.

Connections and Ratings
4 - 45
The second connection allows the
MOI-7 to connect directly to a Style 7
network. This connection is called a
Remote Style 7. In this configuration all
the terminals of TB1 are used. Install
the MOI-7 at any point along the Style
7 network except at either end. The
Style 7 network must terminate on a
NET-7 module to insure proper supervi-
sion of the network. Each MOI-7
connected directly to the network
wiring occupies one of the 32 network
nodes. Do not use connector P5 in
this configuration.
The third connection is also Style 7.
This connection is called a Local Style 7
and its advantage is that it does not
use up a network node. In this configu-
ration the MOI-7 communicates
through the NET-7 installed in the
enclosure. In order for the MOI-7 to
use the NET-7, it must connect to the
8-wire ribbon cable on either the
MMB-1/-2 or the PSR-1 through
connector P5. This limits the distance
an MOI-7 can be located from the
MMB-1/-2 or the PSR-1. An eight foot
cable (MER-8, P/N 500-694147) is
available for this purpose. The MOI-7
must be located in a close nippled
