What modules are available to expand the MXL beyond its base configuration, and what is the maximum supported cabinet and loop count?

The MXL-IQ supports a maximum of 4 analog loops and can be networked to include up to 63 systems using the NIM-1W module (Page 12, 24) [1].

Expansion is achieved by adding MOM-2 (2-slot) or MOM-4 (4-slot) card cages to house optional modules (Page 22) [1].

Available expansion modules include:

• ALD-2I: Adds two analog loops, each supporting up to 60 intelligent devices (Page 19) [1].

• CRM-4 / CSM-4 / CZM-4: Provides 4 relay contacts, 2 signal circuits (NACs), or 4 conventional initiating zones respectively (Page 20) [1].

• NIM-1W: Used for networking multiple panels, interfacing with VESDA, or connecting to foreign systems (Page 24) [1].

• MOI-7: A driver module that supports up to 8 MID-16 input or MOD-16 output modules for graphic annunciators (Page 22) [1].

• Communication Modules: Includes the CMI-300 for CXL system connection, MDACT serial dialer, LLM-1 leased line module, and D2300CP fiber optic interface (Page 19-22) [1].

• CCU/M: An alphanumeric interface for sending system information to pagers (Page 19) [1].
