The Null Control-By-Event AM2020/AFP1010 Control-By-Event
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 soft-
ware 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/AFP1010 system- 9This 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 PWRC upon
system reset).
