1-14 OPTIONAL REMOTE DEVICES
In addition to expansion cards, optional remote devices can be used to expand the functionality of the
FenwalNET 8000-ML system. These devices connect to the FenwalNET 8000-ML but reside outside
the main enclosure.
1-14.1 Remote Devices Using RS485 Bus to MCB
The FenwalNET 8000-ML system’s Main Controller Board includes an RS485 bus which can
communicate with the following remote devices:
• Remote LED Annunciator Module (R-LAM)
• Remote Display Control Module (RDCM)
The FenwalNET 8000-ML supports the use of:
• up to 16 LED Annunciator Modules
• up to 15 Remote Display Control Modules
Note: The total number of remote devices cannot exceed more than 31 addresses. If an integrated
LED Annunciator is included in the FenwalNET 8000-ML, the total number of remote devices
cannot exceed more than 30 addresses.
1-14.1.1 REMOTE LED ANNUNCIATOR MODULE
The Remote LED Annunciator Module (R-LAM) is an optional module which drives the display of
zone information and fits into the Remote Enclosure. The R-LAM provides 48 independently-
programmable microcontroller-controlled LEDs (red/yellow) with space available to place a label to
identify the event being annunciated. In addition, three system-level LED outputs are provided for
the following general conditions: Module Power, Trouble and Signal Silenced. Two system-level input
circuits for functional switches are reserved for Signal Silence and System Acknowledge/Self-Test
commands.
Note: The file LAM label template.doc is provided on the FenwalNET 8000-ML User Disk, P/N 06-
220289-001, to assist with customized labeling. Text for the labels can be entered into preset
form fields (up to two lines of text per window). Cut the strips with a scissors and slide them
into the LAM from the top, retaining the top tab for easy removal.
Refer to Figure 1-13 for an illustration of the Remote LED Annunciator Module. Refer to Appendix
E for an illustration of the integrated LED Annunciator used in Canadian Applications.
