INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS
SOUND AND LIGHT SIGNAL CONTROLLER
1.)
GENERAL FUNCTIONS AND DESCRIPTION
-
The function of the M-522 Sound and Light Controller is to provide convenient operation of
sound signaling devices including navigation horns (ship’s whistles), and Morse Light from a
single control panel. At-Will signaling of any sounding device or light connected can be
accomplished from this panel. Automated signals for Restricted Visibility and Maneuvering
Signaling, as required by IMO (COLREGS) are programmed for output from this unit. In
addition, the M-522 generates the SOLAS General Emergency Alarm Signal and Abandon Ship
signals, to be activated by external push buttons if installed. External General Alarm Systems
that generate the GEA signal can be alternatively be connected to the M-522, passing the signal
through to all sound devices and lights connected to the M-522. The M-522 Sound and Light
Control is also designed to be operated in conjunction with external Sound Surveillance Systems
and/or Public Address systems.
Multiple M-522 units can be utilized on the vessel and will communicate with each other in
cases where multiple control stations are required. The M-522 operates on both A.C. and D.C.
electrical current and thereby will operate on the main voltage of the vessel, and on the backup
24 Volt D.C. emergency voltage in case of main power failure.
The M-522 is a compact solid state electronic control enclosed in an IP65 gasketed enclosure that
allows for bulkhead or console mounting. It includes three watertight cable glands for 10-14 mm
cable entry. All electrical connections are made internal to the enclosure. The unit is operated
from a flush mounted, dimmable, illuminated membrane switch keypad with embossed keys.
