WIRING
!
CAUTION: For terminals 7-15 do not use looped wire under terminals. Break wire run to provide for proper supervision of connections.
With detector head removed, connect one of the appropriate dedicated power sources to the applicable terminals (see above). Replace detector head and
the unit will be energized. The green pilot LED will be illuminated, and when pressing the test/reset button, 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).
In the event of a fire alarm, certain equipment may be required to be shut down. For example, shut down may be achieved by interrupting the fan supply
source to that particular piece of equipment when wired as indicated below.
