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). 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 appli-
ances. 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. Using Multiple NAC Power Extenders from an FACP:
AL602/AL802/1002ADA220 units are designed to follow (replicate) the coded sequence, generated by a manu-
facturer's sync module. One (1) or more units can be triggered. Connect the output of the FACP module to Input 1
and Input 2 Terminate the input circuit with the EOL or 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
sycnchronization between NAC Power Extenders.
