Monitor Modules Description
6.1.3 Dual Monitor Module
M300DJ is similar to the M300MJ, except intended for use in intelligent two-wire systems
providing two independent Style B (Class B) IDCs at two separate, consecutive addresses.
Figure 6.3 Dual Monitor Module
6.1.4 Miniature Monitor Module
M301MJ is intended to monitor a Style B (Class B) IDC; it is offered in a smaller package for
mounting directly in the electrical box of the device being monitored.
Figure 6.4 Miniature Monitor Module
6.1.5 M300MJ-4-20 4-20mA Monitor Module
M300MJ-4-20 is intended for use in intelligent, two-wire systems, allowing Control Panels to
interface and monitor two-wire or three-wire sensors with a 4-20mA signal output.
