L-1 INTRODUCTION
This manual contains the information necessary to sup-port the FenwalNET 2000 Remote Display Control Mod-ule (RDCM) (Figure L-1), P/N 74-300000-502 and Remote Display Module (RDM) (Figure L-2), P/N 74-300000-501.
Both modules function as remote addressable adjuncts to the FenwalNET 2000 and mimic the main control panels LCD and LED front displays. Additionally, the RDCM con-tains system control switches and a tactile response nu-meric keypad. These controls match the FenwalNET 2000 layout. The RDM does not permit operation of the control features (operation is read only). The RDCM is key and password secured, with the password being the same one used on the associated FN-2000 panel.

Module installers must be fully factory trained in all aspects of the FenwalNET 2000 System. Additional supporting documentation is also contained in this manual and in the FenwalNET Configuration Soft-ware (FCS) Program, Users Guide 74-225, P/N 06-235739-001.
L-2 GENERAL DESCRIPTION
The RDCM and RDM communicate with the FenwalNET 2000 via an RS-485 interface (one pair #18 AWG, twisted/shielded wire) in a multi-drop configuration capable of supporting up to 15 RDCM display/control and 16 RDM display only modules. The installation can be in any combination of RDCM/RDM modules so long as the maximum quantity for each module is not exceeded. The RDCM, in addition to emulation of the FenwalNET 2000 LEDs and 2x40 LCD displays, pro-vides remote access to the system and, if programmed, the FenwalNET 2000 network panel(s) and menu op-tions via this emulation of the FenwalNET 2000 front panel function and numeric keys.
Remote power is required and can be provided by the control panel PSU or a separate supply UL Listed for fire alarm application. In each instance, remote power is supervised by the RDCM and RDM with failure dis-played locally and at the control panel. The units also contain a buzzer with sequencing that follows the buzzer contained in the control panel.
The FenwalNET 2000 control panel or one RDCM can be programmed as the master unit to control the Sys-tem under alarm or fault conditions. Operation of an alternate (non-master) unit will grant that module ex-clusive control over the system for 30 seconds. Under these conditions, attempts to input from another ule will prompt a lockout display message on the mod-ule attempting the interrupt. This acts to prevent conflicting inputs. Under all circumstances, the master will be granted immediate system control.
L-2.1 Operator Interface
All operator interfaces are contained in the front panel assembly. Operator inputs are passed to the Fenwal-NET 2000 for processing.
The RDCM operator-interface function keys are:
Acknowledge: Acknowledge alarms/troubles and silence all local buzzers.
Silence: Silence signal/audibles after Acknowledge.
Reset: Reset latched alarm conditions.
Scroll: Review active alarms/troubles.
Note: Drill operation is available through the FenwalNET 2000 menu.
The RDCM operator interface needed to enter the pass-word and access the FenwalNET 2000 menu is pro-vided via the alphanumeric keypad:
0 - 9: Used to enter digits to access FenwalNET 2000 menus.
Delete: Used to exit menu and correct entries.
Enter: Used when selecting from FenwalNET 2000 menu.
Note: Operation of above keys will be hereinafter described.
The RDCM and RDM operator interface status LEDs for monitoring the FenwalNET 2000 and remote mod-ules are:
Alarm: Indicates an alarm condition.
Trouble: Indicates a trouble condition.
Silence: Indicates FenwalNET 2000 signal/audibles have been silenced after Acknowledge.
Supervisory: Indicates a supervisory condition.
Power-on: Indicates the system is receiving AC power.
Pre-alarm: Indicates a smoke or thermal detector is in pre-alarm condition.
CPU fail: Mounted on main PCB and available to the installer only. Indicates RDCM/RDM processor has failed to initialize.
The LCD operator interface mimics the displays on the FenwalNET 2000 LCD. LED colors used to represent indications are:
Red: Alarm.
Green: Power-on.
Yellow: CPU failure, trouble, silence, supervisory and pre-alarm.
The RDM functions as read only. Therefore, it has a scroll key, but does not provide the other function keys nor an operable keypad.
L-2.2 Interconnection
The RDCM and RDM operate on a shared RS-485 bus which supports wire runs of up to 4000 ft from the FenwalNET 2000 control panel. The primary RS-485 bus from the FenwalNET 2000 will support up to 15 RDCMs and 16 RDMs in any combination not exceed-ing maximum of each module.
L-2.3 Addressing
Address selection is via setting of the 16-way, 4-bit hexadecimal coded rotary switch, SW1, mounted on the printed circuit board. See Figure L-4.
Table L-1. Address Switch Settings h L-2.4 Registration
When the module is addressed and configured using FCS, registration follows the format described in Chap-ter 2, Operation, of this manual for "devices."
L-3 OPERATION
Before proceeding with operations, please become to-tally familiar with FenwalNET 2000 Fire Alarm/Sup-pression Control System manual, especially the sections on Active Alarm Mode, Active Supervisory Trouble Mode and Active Trouble Mode. Please note differences between latching and non-latching Active Alarm Modes.
For RX/TX loop input devices. To set either latching or non-latching, please refer to P/N 06-235739-001, Fen-walNET Configuration Software (FCS) Program, FCS Operations chapter.
The following example is for latching alarm mode (for these examples, assume the device to be manual re-lease, address 1004).

In Normal Standby Mode, the display will show:
SYSTEM STATUS NORMAL 10:00AM 06-08-99 FENWALNET 2000
In practice, the actual local time and date will be pre-sented.
When a RX/TX loop device goes into active alarm, the display will show:
1004 ALARM ON - MANUAL RELEASE Default or user text
L-3.1 Switch Functions
The switch functions are listed in sequence of use:
L-3.1.1 ACKNOWLEDGE
All ALARM ON, ALARM OFF, TROUBLE ON/OFF, or SUPERVISORY ON/OFF messages must be acknowl-edged by operation of this switch. Multiple alarms must be individually acknowledged, all other multiple inputs will default to individual acknowledge, but may be pro-grammed to global acknowledge by accessing the set
menu from the FenwalNET 2000 or any RDCM.
The RDCM will pass the acknowledge input to the Fen-walNET 2000 causing its LED to go from a pulsing to a steady mode, and the buzzer to silence.
The FenwalNET 2000 sends a global command to si-lence all remote RDCM/RDM buzzers.
The FenwalNET 2000 sends out a global lockout com-mand to all other RDCMs. This gives the calling device exclusive control over the system for 30 seconds. Un-der these conditions, attempts to input from another module will prompt a lockout display message (See Paragraph L-3.1.2 for example) on the module attempt-ing the interrupt to prevent conflictattempt-ing inputs. Under all circumstances, the module (or control panel) pro-grammed as the system master will be granted imme-diate system control.
The display at the calling device will then show:
1004 ALARM ON ACK - MANUAL RELEASE Default or user text
(The default or user text is that entered at the associ-ated FN-2000 panel. This message cannot be changed from the RDCM.)
Then the display will show how many active alarms are still present in the system (if any), and subsequently display how many active trouble conditions are still present in the system (if any). For example:
001
ACTIVE ALARMS REMAINING
Again in the case of multiple alarms (either On or Off), each event must be acknowledged separately. In the case of multiple troubles, actuation of the
acknowl-edge input may be separate or programmed to global acknowledge. A maximum of 32 trouble message can be displayed/scrolled at any one time.
For non-latching sequence, each ALARM OFF will dis-play and must be acknowledged.
1004 ALARM OFF - MANUAL RELEASE Default or user text
In the event of loss of communications between the RDCM and the FenwalNET 2000 on the RS-485 bus, the local buzzer will sound and the trouble LED will light.
L-3.1.2 SILENCE
When all alarm and trouble conditions have been ac-knowledged, operation of the silence switch will have the following results:
The RDCM will pass the silence input to the Fenwal-NET 2000 causing all outputs programmed for silence to de-energize.
The FenwalNET 2000 sends out a global lockout com-mand to all other RDCM(s). This gives the calling de-vice exclusive control over the system for 30 seconds.
For these examples, assume RDCM address 02. If an-other (non-master) module attempts an interrupt, the following lockout message will display for 5 seconds:
RDCM 02 IN CONTROL
Note: RDCM 02 is the default. This message can be customized in FCS. Please refer to the Fenwal-NET Configuration Software (FCS) Program Manual.
After the 30 second control period, any other module can provide system inputs (unless a module pro-grammed as system master assumes control).
L-3.1.3 RESET
After all active alarms and troubles have been cleared, input devices programmed to the latching sequence will show:
XXX
ALARMS ACTIVE
Input devices programmed to the non-latching se-quence will show:
NO ACTIVE ALARM REMAINS
Now, operation of the reset switch will have the fol-lowing results:
The RDCM will pass the reset input to the FenwalNET 2000 causing all conditions programmed to cancel on reset to de-energize.
The FenwalNET 2000 sends out a global lockout com-mand to all other RDCMs. This gives the calling device
exclusive control over the system for 30 seconds and dis-plays the following message:
SYSTEM RESET
If there are no further key entries at the calling device (ad-dress 02), and no further system events are detected, all modules and the FenwalNET 2000 will display the Sys-tem default message:
SYSTEM STATUS NORMAL 10:00AM 03-08-99 FENWALNET 2000
In practice, the actual local time and date will be presented.
In the event of an RDCMs microprocessor going into fault condition, actuation of hardware switch S3 located be-hind the display membrane will cause a hardware reset of the microprocessor.
L-3.1.4 SCROLL
When the Scroll key is pressed during any active sys-tem event, the following will result:
The FenwalNET 2000 sends out a global lockout com-mand to all other RDCM(s). This gives the calling device (address 02) exclusive control over the system as de-scribed in reset above.
Note: The RDM scroll key does not provide the global lockout command.
The FenwalNET 2000, RDCMs and RDMs will then be updated by the next event in the buffer.
When a Scroll key is actuated at any RDCM, RDM or the FenwalNET 2000, the resulting scroll display is sent globally to the system.
LED Test Feature: With no active inputs, press and hold the scroll key for 2 seconds. All LEDs will light for five seconds.
System Information Entry Keys: To enter passwords and gain access the FenwalNET 2000 menu functions, the relevant keys are:
Numeric 0-9: Enters password and system function information.
Enter: Enter information into the system menu.
Delete: Exit system menu and correct wrong entries.
To enter the password, press the 0 key. The RDCM opens the password entry menu and displays:
PLEASE ENTER PASSWORD
Each key entry will then display the # character:
PLEASE ENTER PASSWORD
####
If the password entry is incorrect, the display will be-come:
PASSWORD ENTRY FAILED
The RDCM will request another password entry request, and, if correct, the FenwalNET 2000 will send the 30 second global lockout command to all other RDCMs.
The calling device (address 02) will then have access to the FenwalNET 2000 menu. Please refer to this manual for menu operating instructions.
If during the password entry sequence any key other than the numeric key (except Delete) is pressed before the
enter key, the FenwalNET 2000 will update the RDCM with the default display.
L-3.2 LED Status Display
The front panel display LEDs will operate in three modes:
Off: No system activity.
On Continuously: Acknowledge alarm or trouble.
Pulsing: 1 second on, 1 second off; active alarm or trouble.
L-3.3 LCD Display
With no active events in the system, all RDCM/RDMs will display the default message:
SYSTEM STATUS NORMAL 10:00am 03-08-99 FENWALNET 2000
FenwalNET 2000 is the default message. This can be customized by FCS. Please refer to the FenwalNET Con-figuration Software (FCS) Program manual.
L-3.4 Password Data Structure
Two system levels are available from the RDCM. These are: Level 1, User Level and Level 2, Installer Level. Please refer to the Menu Function and Menu Structure sec-tions of the FenwalNET 2000 Fire Alarm/Suppression Control System manual for descriptions of the capabili-ties available through these levels.
Each FenwalNET 2000 is shipped from the factory with default passwords for Level 1 of 987 and Level 2 of 1865.
Default passwords can be customized in the level 2 Set Menu Function. Changing passwords for the system can be accomplished from any RDCM or directly from the FenwalNET 2000.
L-3.5 RDCM/RDM Local Trouble Conditions The RDCM/RDM is supervised for failure of the power supply and failure to communicate with the FenwalNET 2000 during the polling routine. The power failure dis-play is:
REMOTE PSU FAULT ON
RDCM XX
If no communication is detected with the FenwalNET 2000 during the polling routine and the PSU is active, a local trouble message will be displayed on the RDCM/
RDM.
