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.
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.
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. The panel trouble is non-latching: when the correct number of annunciators is detected the
troubles will clear.
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.
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.
