Section 19: PC4702BP Output Programming
19.1 Alarm Notification Output Types
Each output on the PC4702BP may be programmed for one of the
following output types. The system will also require that you pro
-
gram a partition mask for each output. Toggle on or off partitions
01-08 to select which partitions will activate the output:
IMPORTANT NOTE: A fire system within a single building should
not be partitioned so that audible or visual alarm notification appli
-
ances operate in one partition and not another. Even though the sys-
tem may be partitioned for security control purposes, all fire alarm
notification appliances in all system partitions MUST be activated on
a fire alarm from any system partition in the building. The fire alarm
portion of the system must appear to operate as a single partition.
Steady Fire (49)
For this output type, the output will turn on steady upon any alarm
from a Fire type zone with the Audible zone attribute enabled.
This output type would be used for fire strobes when it is required
to turn the Fire Strobe lights off when the signals are silenced.
Temporal Pattern Fire (50)
For this output type, the output will follow the standard temporal
pattern upon any alarm from a Fire type zone. The temporal pat
-
tern is 0.5s ON, 0.5s OFF two times and then 0.5s ON and 1.5s
OFF. This pattern is repeated until the signals are silenced.
This zone type would be used for audible fire alarm notification
appliances such as horns or bells. This zone type would not be
used for visual notification appliances (strobes).
CSFM Fire (51)
For this output type, the output will follow the California pattern
upon an alarm from a Fire type zone. The California pattern is 10s
ON and 5s OFF. This pattern is repeated until the signals are
silenced
This zone type would be used for audible fire alarm notification
appliances such as horns or bells. This zone type would not be
used for visual notification appliances (strobes).
Pulsed Fire (52)
For this output type, the output will activate upon an alarm from a
Fire type zone. The output will pulse ON for 0.5s and OFF for
0.5s. The pulsing will continue until the signals are silenced. This
zone type would be used for audible fire alarm notification appli
-
ances such as horns or bells. This zone type would not be used for
visual notification appliances (strobes).
Fire Strobe (53)
For this output type, the output will turn on steadily upon an alarm
from a Fire type zone with the Audible zone attribute enabled.
The output will
not turn OFF upon signal silence but only on Fire
Reset.
This zone type would be used for visual fire alarm notification
appliances when it is required to keep these appliances on once
any audible appliances have been silenced.
19.2 Programming PC4702BP Outputs
Ref #: [000707XXYYZZ] where:
XX = PC4702 number
YY = 01-02 for Bell output 1 or 2
ZZ = 49-53 for output type
Each PC4702BP has two supervised outputs each rated at 24 VDC
FWR, 2.0 Amps. The system can have up to four PC4702BP pan-
els providing up to eight alarm notification appliances. The
PC4702BP panels are connected to the main PC4020 panel via
the 4-wire Combus, allowing them to be located throughout the
premises.
To program the PC4702BP bell zones for one of the output types
described in Section 3.1, enter the appropriate reference number
and select the desired output type for that output.
NOTE: Bell outputs on the PC4020CF or PC4204/PC4204CX can-
not be used for commercial fire applications as they are not super-
vised for short circuits. These outputs could be used for Burglary
applications only.
19.3 Fire Bell Options
Ref #: [000200] Fire Timeout (Y)
Ref #: [00020300] Bell Cut-off (004)
Ref #: [00020311] Fire Silence Del (000)
If the Fire Timeout system toggle option is enabled, any fire
alarm will activate the alarm notification appliances for the Bell
Cut-off time. The Bell Cut-off time is default programmed at 004
minutes. If the Fire Timeout option is disabled, a fire alarm output
can only be silenced through user intervention.
NOTE: Some jurisdictions may not allow automatic signal silencing.
For these applications, disable the Fire Timeout option.
The Fire Silence Delay can be programmed for jurisdictions that
require a minimum time be set before a user can manually silence
fire alarms. The Bell Cut-Off time must be equal to or greater than
the Fire Silence Delay time. The message “SILENCE INHIB
-
ITED FOR [time remaining] MIN” will be displayed for three
seconds when a user attempts to silence the alarm.
19.4 Partitions and Fire System Configuration
A fire system within a single building must not be partitioned
such that audible or visual alarm notification appliances would
operate in one partition and not another.
Even though the system may be partitioned for security control
purposes, any fire zone on any partition in the building must acti
-
vate all fire alarm notification appliances in all system partitions.
The PC4020 provides two methods for achieving these results.
Fire Configuration 1
• Assign all fire zones to one partition. Do not program fire
zones as ‘silent’.
• Assign all PC4702 Bell zones to the same Partition as the fire
zones.
• Assign at least one fire keypad to the same partition as the fire
zones.
• Zones on the PC4701 module are always global and do not
require partition assignment.
• Other types of zones may also be assigned to this partition
without effecting the fire operation as described below.
Operation
On alarm, from any fire zone in this partition, the fire auto-scroll
display will only show on keypads assigned to the fire partition
and on any system global keypads.
The waterflow and 2-wire smoke zones on the PC4701 module
will show, in the auto-scroll mode, on
all partition and global key-
pads. If a zone on the PC4701 is in alarm, then fire silence and
reset can be done from any partition keypad.
If the alarm is from a partition zone (not PC4701) then fire alarm
silence and reset can only be done directly on the fire partition
keypad(s). To silence from other partition keypads or a global
keypad requires that the keypad be loaned to the fire partition.
