Conduit Knockouts:
Determine knockout size required based upon installation wiring.
TiP:
¾" knockout is typically used for power
Select knockout. To remove, eliminate the node with a pair of sidecutters or similar, place a
screwdriver at the opposite edge of the knockout from the node and tap with a hammer until the
knockout breaks out. Clean all holes before installing the proper conduit fitting.
TeRMiNAL AND POweR CONNeCTiONS
Prior to connecting input power to the duct unit, determine the correct input voltage/current
availability and ensure it is connected to the correct terminals.
With detector head removed, connect one of the appropriate dedicated power sources to the
applicable terminals (see below). Replace detector head and press and hold the cover removal
switch (COVER REMOVAL) and the unit will be energized. The green pilot LED will be illuminated,
and when pressing the test/reset button (TEST RESET), the red alarm LED will be illuminated. This
test confirms the correct basic operation of the duct smoke unit, excluding the detector head (see
functional testing).
