Operation
IMPORTANT !
The Model 3992 Siren has two distinct modes of operation. These are Hit-N-Go mode and
SCROLL mode. The desired mode of operation can be selected via the amplifier rear panel slide
switch. Each mode will affect the siren operation as described below. The Hit-N-Go mode should be
most familiar to existing
users.
The Park Kill features will, in some cases, prevent the siren from producing siren tones. The
siren will not produce tones when the vehicle is in "PARK" if the PKILL feature has been connected.
To test the siren tones the vehicle must not be in "PARK". The following assumes that PKILL has not
been activated.
Operation - Hit-N-Go Mode Selected
The Hit-N-Go mode is designed to allow the user to instantly change siren tones by utilizing the
Remote input on the siren. By depressing the switch connected to the Remote input of the siren (usually the
vehicle Horn Ring switch), the user can cause the siren to change tones for an eight second period after
which time the siren will revert to the previous tone. The InterClear output will also be activated during this
period.
