Remote Annunciator Operation
12.0 Remote Annunciator Operation
The FX-350 supports two types on annunciators: conventional LED/switch annunciators and a
shared display (LCD) annunciator. Both types are connected to the panel via the RS-485 serial
link.
12.1 Conventional Annunciators (RA-1000 Series)
The FX-350 is designed to interface with the RA-1000 series of conventional LED
annunciators. The LEDs may be configured to zone status indicators. Each conventional
annunciator contains a local alert buzzer. Under normal operation the alert buzzer is controlled
by the system and operates in an identical manner as the one in the main panel. If
communication fails it is processed locally.
12.2 Supervision
The communications with each annunciator is constantly supervised both by the panel and by
the annunciator. If communications fails, the panel will activate the common trouble sequence.
The number of annunciators is set during panel configuration. If there is a mismatch in the total
number of annunciators the panel will generate communications trouble. When the correct
number of annunciators is detected the troubles will clear.
12.3 Shared Display Annunciator (RAM-300LCD)
The shared display annunciator has identical operation to the main shared display and
operates in conjunction with the main display (viewing items in the queues on one shared
display flag the items as viewed on all shared displays). The shared display annunciator
contains a local alert buzzer. Under normal operation the alert buzzer is controlled by the
system and operates in an identical manner as the one in the main panel. If communication
fails it is processed locally. The configuration cannot be performed by the shared display
annunciator.
12.4 Supervision
The supervision of the shared display annunciator is same as for the remote LED
annunciators
The SRM-312 Smart Relay Module is connected on the RS-485 loop along with other remote
annunciators, but provides 12 relay contact outputs which actuate according to the first 12
remote LED groups. The relays are bypassed by Auxiliary Bypass, and the unit is supervised
as one of the (maximum) eight permitted annunciators.
