Receive Only Annunciators
For redundant annunciation of system points, annunciators can be configured as
"Receive Only" annunciators. Receive Only annunciators are not fully supervisable.
Receive Only annunciators intercept information being transmitted to a "Receive/
Transmit" annunciator so that information can be duplicated at an intermediate display
location. When configured for Receive Only operation, they cannot send information to
the system, therefore they cannot perform remote functions such as Acknowledge,
Silence, or Reset. Control switches on Receive Only annunciators can be used only for
local functions, such as lamp test.
supervised by installing the modules "upstream" of fully-supervised Receive/Transmit
annunciators along the EIA-485 line.
Receive/Transmit Annunciators
Annunciators that are configured to serve as full function annunciators can both receive
status information as well as transmit commands to the control panel. This allows the
annunciator to remotely execute functions of the control panel in addition to displaying the
status of the system.
