APPENDIX L
REMOTE DISPLAY CONTROL MODULE
AND REMOTE DISPLAY MODULE
L-1 INTRODUCTION
This manual contains the information necessary to support
the PEGAsys LV Remote Display Control Module (RDCM)
(Figure L-1), P/N 76-300000-502, and Remote Display Mod-
ule (RDM) (Figure L-2), P/N 76-300000-501. Both modules
function as remote addressable adjuncts to the PEGAsys LV
and mimic the main control panel’s LCD and LED front dis-
plays. Additionally, the RDCM contains system control
switches and a tactile response numeric keypad. These con-
trols match the PEGAsys LV layout. The RDM does not per-
mit operation of the control features (operation is “read only”).
The RDCM is key and password secured with the password
needed being the one used on the associated PEGAsys LV
panel.

Module installers must be fully factory trained in all as-
pects of the PEGAsys LV system. Additional supporting
documentation is also contained in this manual and in the
PEGAsys™ Configuration Software (PCS) manuals, P/Ns
76-014 and 76-015.
L-2 GENERAL DESCRIPTION
The RDCM and RDM communicate with the PEGAsys LV
via an RS-485 interface (one pair #18 AWG, twisted/
unshielded wire) in a multi-drop configuration capable of
supporting up to fifteen (15) RDCM display/control and six-
teen (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 PEGAsys LV
LEDs and LCD displays, provides remote access to the
system and, if programmed, the PEGAsys LV network
panel(s) and menu options via this emulation of the
PEGAsys LV front panel function and numeric keys.
Remote power is required and can be provided by the con-
trol panel PSU or a separate UL Listed supply for fire alarm
application. In each instance, remote power is supervised
by the RDCM and RDM with failure displayed locally and
at the control panel. The units also contain a buzzer with
sequencing that follows the buzzer contained in the con-
trol panel.
Either the PEGAsys LV control panel or one RDCM can
be programmed as the master unit to control the system
under alarm or fault conditions. Operation of an alternate
(non-master) unit will grant that module exclusive control
over the system for 30 seconds. Under these conditions,
attempts to input from another module will prompt a lock-
out display message on the module attempting the inter-
rupt. This acts to prevent conflicting inputs. Under all
circumstances, the master will be granted immediate sys-
tem control.
L-2.1
Operator Interface
All operator interfaces are contained in the front panel as-
sembly. Operator inputs are passed to the PEGAsys LV
for processing.
The RDCM operator-interface function keys are:
• Acknowledge: Acknowledge alarms/troubles and
silence all local buzzers.
• Silence: Silence signal/audibles after Acknowl-
edge.
• Reset: Reset latched alarm conditions.
• Scroll: Review active alarms/troubles.
Note: Drill operation is available through the PEGAsys
LV menu.
