ADDRESSABLE MODULES
The Cheetah Xi 50 system uses intelligent input and output modules to provide an interface between the
control panel and conventional notification and initiating devices. The operating parameters for each module
are downloaded to the device during system configuration into nonvolatile memory. When an input device
(detector or input module) determines that action should be taken, it transmits a message over the panel’s
SLC loop. Output devices receive this message and use their downloaded parameters to determine if they
should take action. Each module is provided with a tricolor LED to indicate instant device status (green =
normal; yellow=trouble; red = active).
The modules are connected to and receive their operating power (15-30VDC) from the host control panel via
the panel’s signaling line circuit (SLC). The SLC loop is capable of supporting up to 50 addressable devices
in any combination of detectors and modules. Each addressable device is assigned a unique SLC address
that allows it to be identified not only by the system controller for device supervision, but by other SLC devices
as well to facilitate peer to peer system operation. A brief description of each addressable module and its
features is provided in this section for reference purposes.
Refer to Fike document 06-369-2, “Cheetah Xi 50 Operations Manual” for details of module operation and
available programming features.
Refer to installation and maintenance instructions supplied with each module for more information.

MINI MONITOR MODULE, P/N 55-045
MINI MONITOR MODULE WITH ISOLATOR, P/N 55-050
The Mini Monitor Module (See Exhibit 3-38) can be used to monitor
normally open or normally closed contacts of conventional initiating
devices. It is designed for mounting in a small junction box directly
behind the monitored device. This module will monitor a Class B
wired input device only using the 39K ohm end of line resistor. The
isolator version provides complete short circuit isolation for NFPA
Class X wiring.
3.9.2
MONITOR MODULE, P/N 55-041
MONITOR MODULE WITH ISOLATOR, P/N 55-046
The Monitor Module (See Exhibit 3-39) is used to monitor normally
open or normally closed contacts of conventional initiating devices
wired either Class B or Class A. Class B wiring requires the use of a
39K ohm end of line resistor. The isolator version provides complete
short circuit isolation for NFPA Class X wiring. A module cover plate
(not shown) is included with the module.
