Step Four: Connecting The External Siren
(Optional)
The Siren is a recommended accessory due to typically noisy
engine rooms. Several different types of sounds can be selected
depending on how the unit is wired. The brown harness cable is
for the external siren. Connect the white

wire to the siren
terminal marked 12V and the brown (

) wire to the sound terminal
of your choice. Mount the siren to a surface where it will not be
exposed to moisture as they are not waterproof. Route and dress
the siren cable to the MCU. Siren cables can be shortened as
necessary. Unused siren cables (twin engine installations use
only one siren) can be cut but should be properly capped and not
left exposed.
