Programming—IFC-1010/2020 Programming
Each IFC-1010/2020 has 240 software zones for both CBE and CCBE
programming. Although there are 240 software zones, only Zones 2-240
can have CCBE equations associated with them. Since a zone boundary
must be declared, at least one of the software zones is a forward activating
zone and cannot have a CCBE equation associated with it. If Zone 1 is
used as the zone boundary, then there are only 239 zones left for CCBE
programming.
It is possible for a reverse activated software zone to have both a CBE and
CCBE equation associated with it. If this occurs, the software zone
becomes active if either equation becomes active. The format for a CCBE
equation is the same as a CBE equation. The operators for CCBE can only
AND(, OR(, and NOT(. The operands for CCBE are most often a zone
with the format N(XXX)Z(YYY), where XXX is the node number for the
particular panel on the network and YYY is one of the 240 software zones
available to CCBE programming.
The simplest type of CBE is the Null
,
which means empty. For initiating
devices
,
the Null is denoted by entering
( )
as the CBE. In response to an
alarm on a device programmed with a Null CBE, the IFC-1010/2020 does
the following:
•
Initiates a System Alarm condition
(Alarm LED flashes, piezo sounds, and the Form-C alarm contacts on
the CPU are activated).
•
Activate no control modules or software zones
(No notification appliances will sound and no output relays are
activated due to the fact that there are no entries in the CBE for this
initiating device).
N12
For Output Devices, the Null is denoted by entering OR
( )
or
( )
. A control
module programmed with a Null CBE is not activated unless it is included
in the CBE of a software zone or initiating device.
Note: Entering
(
is equivalent to entering OR
(
.
A control module is needed to reset power to four-wire smoke detectors in
an IFC-2020 or IFC-1010 system.
N13
This module must
not
be activated
in response to an alarm condition. Rather, this module must be activated
only during system reset. This can be accomplished by assigning the
module a Null CBE and the Software Type ID PWRC (the control panel
automatically resets modules with Type PWRC upon system reset).
