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 program a partition mask for each output. Toggle
on or off partitions 01-08 to select which partitions will acti-
vate the output:
IMPORTANT NOTE: A fire system within a single building
should not be partitioned so that audible or visual alarm
notification appliances operate in one partition and not
another. Even though the system may be partitioned for
security control purposes, all fire alarm notification appli-
ances 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 pattern 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 notifi-
cation appliances such as horns or bells. This zone type
would not be used for visual notification appliances
(strobes).
NOTE: This option is required for residential fire applica-
tions.
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 notifi-
cation 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 appliances such as horns or bells. This
zone type would not be used for visual notification appli-
ances (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 notifica-
tion 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 V FWR, 2.0 Amps. The system can have up to four
DC
PC4702BP panels 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 refer-
ence number and select the desired output type for that
output.
NOTE: Bell outputs on the PC4020CF or PC4204/PC4204CX
cannot be used for commercial fire applications as they are
not supervised for short circuits. These outputs could be
used for Residential Fire and/or 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 Fire Timeout system toggle option is enabled, any fire Fire Timeout Fire Timeout
alarm will activate the alarm notification appliances for the
Bell Cut-off time. The Bell Cut-off time is default pro- Bell Cut-off
Bell Cut-off Bell Cut-off
grammed at 004 minutes. If the Fire Timeout option is dis-
abled, 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 Fire Silence Delay can be programmed for jurisdictions
Fire Silence Delay Fire Silence Delay
that require a minimum time be set before a user can manu-
ally silence fire alarms. The Bell Cut-Off time must be equal
to or greater than the Fire Silence Delay time. The message
"SILENCE INHIBITED 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 parti-
tioned such that audible or visual alarm notification appli-
ances 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 activate 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.
