Genesis Master mode
In Genesis Master mode, Sense 1 is connected to a visible zone and Sense 2 is
connected to an audible zone. All NACs are activated when Sense 1 activates.
Continuous NACs generate Genesis audible on/off signals based on the Sense 2
input circuit.
Nondelayed mode
Nondelayed mode is intended to support coders. In this mode, there is no delay
between activation of the sense input and activation of the NAC.
In nondelayed mode, switch SW1-3 controls which NACs activate when the
sense circuits activate. The correlations do not affect output circuits that are
operating as AUX circuits.
The following table details which NACs activate when the sense circuits activate.

In nondelayed mode, SW2-5 can be used to generate sync pulses for NACs
configured in continuous mode. This supports applications that include Genesis
strobes and conventional audibles. For this operation, the NACs for the audible
signals must be configured in sense follow mode. There is no delay for either the
visibles or the audibles.
Synchronization control (SW1-4)
Switch SW1-4 controls the synchronization of signals with either one- or four-
second delay times. See the topic “Understanding BPS synchronization” for more
information.
Note: When using nondelayed mode, this switch is inactive.
