MMX Monitor Modules
The MMX-101 Monitor Module is an addressable module that is function-
ally and electrically identical to an MMX-1 Monitor Module (Style B
circuits only), but offered in a smaller package for mounting directly in
the electrical box of the monitored contact-type device. When installing
MMX-1 and MMX-101 modules, note the following:
MMX-1 and MMX-101 Modules
Terminate with a SSD A2143-00
ELR (N-ELR in Canada).
1) The Initiating Device Circuit is supervised and current-limited to 210
microamps @ 24 VDC (nominal).
2) The Initiating Device Circuit provides the following services (do not
mix):
a) Fire Alarm Service.
b) Automatic/Manual Waterflow Alarm Service with normally open
contact devices.
c) Sprinkler Supervision with normally open contact devices.
d) Security Service.
3) Maximum IDC loop resistance due to wiring is 20 ohms.
