2.10 2.10 The M300 Monitor Module
The M300 Monitor Module is an addressable module that monitors normally-open contacts and shorting-type alarm
initiating devices. The supervised module circuits can be wired as NFPA Style B or Style D Initiating Device Circuits.
There is no limit to the number of contact-type devices installed on a monitor module circuit. Refer to Figures 2.14
and 2.15 for wiring diagrams.

Connect the MS-9200 Communications SLC Loop to M300 terminals 1 (-) and 2 (+). The M300 occupies one module
address on the Loop. Use the rotary switches on the M300 to set the module to the required loop address.

Connect the normally-open contacts of the alarm initiating devices to a single two-wire circuit (as shown in Figure
2.14). NOTE: This circuit cannot be T-Tapped or branched in any fashion, and must be terminated across the last
device by a listed ELR. Connect the circuit to M300 terminals 6 (-) and 7 (+).
NFPA STYLE D INITIATING DEVICE CIRCUIT NFPA STYLE D INITIATING DEVICE CIRCUIT NFPA STYLE D INITIATING DEVICE CIRCUIT NFPA STYLE D INITIATING DEVICE CIRCUIT NFPA STYLE D INITIATING DEVICE CIRCUIT
Connect the alarm initiating devices to a single four-wire circuit (as shown in Figure 2.15). NOTE: This circuit cannot
be T-Tapped or branched in any fashion . Connect the four-wire circuit to M300 Terminals 6 (-) and 9 (-), then 7 (+)
and 8 (+).
TEST SWITCH TEST SWITCH TEST SWITCH TEST SWITCH TEST SWITCH
The M300 includes a magnetic test switch located near the center front of the module. Activation of this switch will
cause an open circuit indication in the Style B/D loop.

2.11 2.11 The M301 Monitor Module
The M301 Monitor Module is an addressable module that is functionally and electrically identical to an M300 Monitor
Module (Style B circuits only), but offered in a smaller package for mounting directly in the electrical box of the
contact-type device being monitored.

1. The Initiating Device Circuit is supervised and current-limited to 230 microamperes @ 24 VDC (nominal).
2. The Initiating Device Circuit wiring may be up to 2,500 feet or a maximum of 40 Ohms for the M300 and 20
Ohms for the M301.
3. The Initiating Device Circuit provides the following services ( DO NOT MIX ):
Fire Alarm Service.
Automatic/Manual Waterflow Alarm Service with normally-open contact devices.
Sprinkler Supervision with normally-open contact devices.
4. The maximum SLC loop resistance due to wiring is 40 Ohms.
