AND REMOTE DISPLAY MODULE
L-1 INTRODUCTION
This manual contains the information necessary to support the
PEGAsys Remote Display Control Module (RDCM)(Figure L-1),
P/N 76-300000-502, and Remote Display Module (RDM)(Figure
L-2), P/N 76-300000-501. Both modules function as remote ad-
dressable adjuncts to the PEGAsys and mimic the main control
panel’s LCD and LED front displays. Additionally, the RDCM con-
tains system control switches and a tactile response numeric key-
pad. These controls match the PEGAsys 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 needed
being the one used on the associated PEGAsys panel.

Module installers must be fully factory trained in all aspects of
the PEGAsys system. Additional supporting documentation is
also contained in this manual and in the PEGAsys™ Configura-
tion Software (PCS) Program, User’s Guide 76-014, P/N 06-
235766-001.
L-2 GENERAL DESCRIPTION
The RDCM and RDM communicate with the PEGAsys 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 installa-
tion 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 LEDs and LCD
displays, provides remote access to the system and, if pro-
grammed, the PEGAsys network panel(s) and menu options
via this emulation of the PEGAsys front panel function and nu-
meric keys.
Remote power is required and can be provided by the control
panel PSU or a separate supply UL listed for fire alarm applica-
tion. 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 control panel.
Either the PEGAsys control panel or one RDCM can be pro-
grammed 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 an-
other module 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 im-
mediate system control.
L-2.1 Operator Interface
All operator interfaces are contained in the front panel assem-
bly. Operator inputs are passed to the PEGAsys 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 PEGAsys
menu.
The RDCM operator interface needed to enter the password
and access the PEGAsys menu is provided via the alphanu-
meric keypad:
• 0 - 9 : Used to enter digits to access PEGAsys menus.
• Delete: Used to exit menu and correct entries.
• Enter: Used when selecting from PEGAsys menus.
NOTE: Operation of above keys will be hereinafter described.
The RDCM and RDM operator interface status LEDs for moni-
toring the PEGAsys and remote modules are:
• Alarm: Indicates an alarm condition.
• Trouble: Indicates a trouble condition.
• Silence: Indicates PEGAsys 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-
