The Null Control-By-Event; Cooperative Control-By-Event - Notifier AM2020 User Manual

Cooperative Control-By-Event equations pertain to reverse activated software zones on the AM2020/
AFP1010 NOTI•FIRE•NET system only.
CCBE, like Control-By-Event (CBE), is used to provide a variety of responses based on various combinations
of events (initiating conditions). Where CBE programming controls the interaction between devices and
software zones within one AM2020/AFP1010, CCBE programming controls events between multiple panels
on a NOTI•FIRE•NET system. For example, an addressable initiating device in one panel turning on an
addressable output device of another panel through a reverse activated software zone. The formats and uses for
CBE and CCBE are similar in many ways with the following exceptions:
• Only reverse activating software zones can be programmed with a CCBE equation.
• CCBE equations can only be programmed for software zones from the AM2020/AFP1010 node that
the zones reside in. For instance, if a CCBE equation is to be programmed for software zone 23 of
node 10 the user must program the equation on the AM2020/AFP1010 that is declared as node 10.
• CCBE can only use the AND(, OR(, and NOT( operands.
• CCBE equations have a size limitation of 80 characters.
Forward activating software zones can not have CCBE equations but can be used as operands in
Each AM2020/AFP1010 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 will be a forward activating zone and can not
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 will become 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 be 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 Control-By-Event is the Null, which means empty. For initiating devices, the Null is
denoted by entering ( ) as the Control-By-Event. In response to an alarm on an addressable alarm initiating
device programmed with a Null Control-By-Event, the AM2020/AFP1010 will do the following:
• Initiate a System Alarm condition (Alarm LED flashes, piezo sounds and the Form-C alarm contacts
on the CPU will be activated).
• Activate no control modules or software zones (no notification appliances will sound and no output
relays will be activated due to the fact that there are no entries in the Control-By-Event for this initiating
device).
For Addressable Output Devices, the Null is denoted by entering OR( ) or ( ). Note: Entering ( is equivalent
to entering OR( . A control module programmed with a Null Control-By-Event will not be activated unless it is
included in the Control-By-Event of a software zone or initiating device.
Example - Resetting 4-wire Smoke Detectors
A control module is needed to reset power to 4-wire smoke detectors in an AM2020 or AFP1010 system unless
the resettable power output (TB3 terminals 1 and 2) from the MPS-24A is used. This module must not be activated
in response to an alarm condition. Rather, this module must only be activated during system reset. This can be
accomplished by assigning the module a Null Control-By-Event and the Software Type ID PWRC (the control panel
automatically resets modules with Type ID PWRC upon system reset).
