5.9 Remote Annunciator Operation

The FX-3500 System supports the following types of annunciators

• RAX-LCD-LITE shared display annunciator.

• RAM-3500-LCD shared display annunciator.

• Conventional LED/switch annunciators.

Both types of annunciators are connected to the panel via the RS-485 serial link.

The maximum number of annunciators is seven (7). Configuration of the annunciators is done

via the software configurator.

Ensure that the address DIP switch on each annunciator is set to the same value set in the

configurator. Only the first three (3) DIP switches are used for address configuration.

5.9.1 Supervision of annunciators

• The communications with each annunciator is constantly supervised by the panel and

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.

5.9.2 RAX-LCD-LITE Shared Display Annunciator

• The RAX-LCD-LITE is equipped with a large 4 line x 20 character backlit alphanumeric

LCD display which uses a simple menu system complete with a directional key pad and

switches for Enter, Menu, Cancel and Info.

• 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 the buzzer is processed locally.

5.9.3 RAM-3500-LCD Shared Display Annunciator

• The RAM-3500-LCD operates identically to the main LCD FACP display. For ULC

approved applications some control functions are disabled.
