The M302 Monitor Module is an addressable module that interfaces and monitors UL compatible conventional 2-wire
smoke detectors. (See Fire-Lite Compatibility Document P/N 15384.) The supervised circuit may be wired as NFPA
Style B or D.
COMMUNICATIONS SLC LOOP CONNECTIONS COMMUNICATIONS SLC LOOP CONNECTIONS COMMUNICATIONS SLC LOOP CONNECTIONS COMMUNICATIONS SLC LOOP CONNECTIONS COMMUNICATIONS SLC LOOP CONNECTIONS
Connect the MS-9200 Communications SLC loop to M302 terminals 1(-) and 2(+). The M302 occupies one module
address on the loop. Use rotary switches on the M302 to set the module to the required loop address.

Connect 2-wire smoke detectors to M302 terminals 6 (B-) and 7 (B+) (as shown in Figure 2.16). IDC installation
wiring must not exceed 25 ohms, 12-18 AWG wire. Use a 3.9K ELR across the last initiating device. (See Figure
2.16).

1. IDC and power connections are supervised by the M302 and reported to the MS-9200
2. Maximum current in alarm is 90 mA power limited
3. See Appendix F for device specifications
4. See Appendix A for power supply calculations
TEST SWITCH TEST SWITCH TEST SWITCH TEST SWITCH TEST SWITCH
The M302 includes a magnetic test switch sensor located near the center front of the module. Activation of this
switch by test magnet P/N M02-04-00 will cause an open circuit indication in the Style B/D loop.
