INSTALLATION AND MAINTENANCE INSTRUCTIONS
55-042 Supervised Control Module
BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to the
appropriate control panel installation manual for detailed system information.
If the modules will be installed in an existing operational system, inform the
operator and local authority that the system will be temporarily out of service.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
Control Module, Model 55-042, is used to switch an external power supply
or audio amplifier to notification appliances. In addition to switching the ex-
ternal power, the device will monitor the wiring (while external power is not
switched to the auxiliary devices) to the auxiliary device for open and short
circuits via an end of line resistor. This module is capable of Class A or Class
B operation.
The control module will also have the capability to monitor the external
power input for loss of power (DC voltage supplies only). This feature can
be disabled through device configuration programming. If the external power
is switched to the auxiliary devices and there is a loss of the DC supply, the
control module has the capability of running an algorithm in which the device
will switch back to monitor mode and check the line for short circuits. If no
short exists, the device will reapply the external power. This algorithm can
be enabled when using a DC external supply that is guaranteed to be above
9 volts.

COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a listed compat-
ible control panel.
MOUNTING
The module mounts directly to 4-inch square electrical boxes. The box must
have a minimum depth of 2
1
/
8
inches. Modules must be mounted with the ar-
row facing upward for proper operation of the IR programming tool. Surface
mounted electrical boxes (SMB500) are available from Fike.
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations.
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams. Optional EA-CB may be required to separate power
limited and non power limited wiring in the electrical box.
2. For new installations use the enclosed 39 k
Ω
EOL resistor. For retrofit ap-
plications where the existing 47 k
Ω
cannot be easily replaced, it may be
left in place without loss of performance.
3. Set the address on the module per job drawings using the handheld IR
programmer.
4. Secure module to electrical box (supplied by installer).
NOTE: All references to power limited represent “Power Limited (Class 2)”.
All references to Class A also include Class X.
