3. Non-synchronizable NAC Appliances:
When using NAC appliances not designed to support synchronization feature, it is recommended to use sepa-
rate output circuits for audible notification appliances (horns) and visual notification appliances (strobes). Set dip
switches for the visual notification appliances to follow Input 1 [IN1] and for audible notification appliances to
follow Input 2 [IN2]. This will allow, when using two (2) outputs from the FACP, to support silencing of audible
notification appliances. When using only one (1) FACP output, set all dip switches to follow Input 1 [IN1]. The
units outputs can each be set for the desired NAC drive signal, such as Code 3 or march time sequence (Output
Programming Selection Table, pg. 6). Non-synchronizable Audible Appliances will follow the sequence, when
feature is selected.
4. Triggering One (1) or More NAC Power Extenders from an FACP:
One (1) or more units can be triggered. Connect the output of the FACP module to Input 1 and Input 2.
Terminate the input circuits with the EOL, connecting it to terminals marked [RET + and RET –], or continue
the input circuits to the next NAC Power Extender.
In case FACP does not have any synchronization capabilities and the sync mode is not used,
the notification appliance synchronization will not be provided.

CAUTION: Do not connect any notification appliances on the control circuit interconnecting
FACP outputs (sync module outputs) and inputs of NAC Power Extenders. Applications that
do not employ synchronization module or FACP with synchronization protocol will not provide
NAC synchronization between NAC Power Extenders.
