Appendix A: Operating Control Modules
Optional CMX-2 control modules can be installed on the AIM-200 addressable loop. When
using one or more CMX-2s, four types of control options are available: General Alarm,
Control-by-Zone, Control-by-Module, and Control-by-Detector. The CMX-2 zone mapping
and address assignments required for each control option are described below.
General Alarm - To set up General Alarm, set CMX-2 module address in the range of
01-59 and ensure that it has not been mapped to any zones. If an alarm occurs on the alarm
bus (see Figure 3-3 for wiring information), the CMX-2 will be activated. This type of control
can also be executed using the manual switch on the CPU board alarm relay (manual evacu-
ation).

mapped to any zone.
Control-by-Zone - Control-by-Zone is suited for control-by-floor and floor above/floor be-
low applications. No special treatment is required to execute Control-by-Zone. If the AIM-200
detects an alarm from an intelligent detector or addressable monitor module, it activates
which ever zone(s) are mapped to this device. All CMX-2 modules assigned to the alarmed
zone(s) will be activated.

Control-by-Module - Control-by-Module is a useful function for Air Handling Units (AHUs)
controlled by 4-wire duct detectors. To set up Control-by-Module, set the monitor module
address in the range 60-69. Ensure that a CMX-2 module exists in the address range 70-79
with the same least significant address digit as the MMX-1, MMX-101, MMX-2(s) and that
the CMX-2 module has not been mapped to any zones.

device and is not mapped to
any zones.
