The SiteMaster Model SM16A16Dg8RDoB is a stand alone analog
/ digital annunciator and monitor. As an analog / digital
annunciator, the SiteMaster announces which electrical circuit
has been activated. The Visicon Mark LX- line of annunciator
and monitoring systems is based on 8 point modules that can
communicate with each other and any other control device over
an RS485 bus. This arrangement allows for tremendous flexibility
in system physical design configuration and modular customizing
of accessories. When one of the NO/NC field contacts changes
status the red light flashes (green goes out) and the alarm
horn sounds. Call our toll free number 1-866-221-3131 for
