3. Non-synchronizable NAC Appliances:
When using NAC appliances not designed to support synchronization feature, it is recommended to use separate
output circuits for audible notification appliances (horns) and visual notification appliances (strobes). Program the
FireSwitch 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, program to follow Input 1 [IN1]. The units outputs can each be set for the desired NAC drive signal,
such as Code 3 (Output Programming Selection Table, pg. 6). Non-synchronizable Audible Appliances will follow the
sequence, when feature is selected.
4. Using Multiple NAC Power Extenders from an FACP:
FireSwitch is designed to follow (replicate) the coded sequence, generated by a manufacturer's sync module. Up to
eleven (11) FireSwitch108 units can be synchronized when interconnected with a host FACP. Connect the output of
the FACP module to Input 1 and Input 2 Terminate the input circuit with the EOL (FACP), connecting it to terminals
marked [RET+ and RET-], or continue the input circuit, connecting to terminals marked [RET+ and RET-] to [INP+ and
INP-] of the next unit, when multiple units need to be triggered.
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.
