Intelligent Suppression Control/Fire Alarm System
PEGAsys
stances, the module (or control panel) programmed as the sys-
tem master will be granted immediate 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 associated PE-
GAsys 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 mul-
tiple troubles, actuation of the acknowledge input may be sepa-
rate 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 display 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 PEGAsys 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 acknowledged,
operation of the “silence” switch will have the following results:
The RDCM will pass the silence input to the PEGAsys causing
all outputs programmed for silence to de-energize.
The PEGAsys sends out a global lockout command to all other
RDCM(s). This gives the calling device exclusive control over
the system for 30 seconds. For these examples, assume RDCM
address 02. If another (non-master) module attempts an inter-
rupt, the following lockout message will display for 5 seconds:
RDCM 02
IN CONTROL
NOTE: RDCM 02 is the default. This message can be cus-
tomized in PCS. Please refer to the PEGAsys Con-
figuration Software (PCS) Program Manual
After the 30 second control period, any other module can pro-
vide system inputs (unless a module programmed 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 sequence will
show:
NO ACTIVE ALARM REMAINS
Now, operation of the “reset” switch will have the following re-
sults:
The RDCM will pass the reset input to the PEGAsys causing all
conditions programmed to cancel on reset to de-energize.
The PEGAsys sends out a global lockout command to all other
RDCMs. This gives the calling device exclusive control over the
system for 30 seconds and displays the following message:
SYSTEM RESET
If there are no further key entries at the calling device (address
02), and no further system events are detected, all modules
and the PEGAsys will display the system default message:
SYSTEM STATUS NORMAL 10:00AM 03-08-99
PEGASYS
In practice, the actual local time and date will be presented.
In the event of an RDCM's microprocessor going into fault con-
dition, actuation of hardware switch S3 located behind the dis-
play membrane will cause a hardware reset of the
microprocessor.
L-3.1.4 SCROLL
When the “Scroll” key is pressed during any active system event,
the following will result:
The PEGAsys sends out a global lockout command to all other
RDCM(s). This gives the calling device (address 02) exclusive
control over the system as described in “reset” above.
NOTE: The RDM scroll key does not provide the global lock-
out command.
The PEGAsys, 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 PE-
GAsys, the resulting scroll display is sent globally to the sys-
tem.
• LED Test Feature: With no active inputs, press and hold
the “scroll” key for 2 seconds. All LEDs will light for 5 sec-
onds.
• System Information Entry Keys: To enter passwords and
gain access the PEGAsys menu functions, the relevant keys
are:
• Numeric 0-9: Enters password and system function infor-
mation.
• 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 become:
PASSWORD ENTRY FAILED
The RDCM will request another password entry request, and, if
correct, the PEGAsys will send the 30 second global lockout
