It is important to note that the 3992XAMP is
compatible with the popular RLS series sirens and
may also be used as a 2nd amplifier with these
sirens.
The following features are standard in the 3992 series
sirens (tones and sequences may differ with model and
options):
Instant-On- There is no " ON/OFF " switch. Selecting
any
siren function, or keying the microphone will activate the
selected siren function, assuming the siren is properly installed and the vehicle's ignition is switched on.
Park Kill- This feature deactivates the siren tones when the vehicle is shifted into park. Once PKILL is activated
the siren will remain deactivated until the vehicle is shifted into drive and an
action occurs such as depressing one of the siren control switches or keying the microphone. Any of these
actions will cause the siren tones to start again.
Adjustable Backlighting- Backlighting is independent of siren power. Allows connecting to dimmer if desired.
Automatic Short Circuit Protection- The siren will sense a short circuit on the speaker terminals and
automatically go to standby until the fault is removed. Once the fault is removed the siren will return to normal
operation.
Scroll Mode- Setting the slide switch on the rear of the siren to the SCROLL position will put siren in scroll
mode. This will allow "scrolling" through tones utilizing sharp taps on the horn ring, or a switch, via the Remote
siren input. In this mode holding the horn ring for prolonged durations will produce the Air Horn sound. See
OPERATION section for further details.
Hit-n-Go Mode - Setting the slide switch on the rear of the siren to the Hit-N-Go position will put the siren in the
Hit-n-Go mode. This mode will be most familiar to existing
users. A seven second override is
standard for all tones when activated by the Remote input. See OPERATION section for details.
Automatic Siren Tones - Industry standard Wail, Yelp, and Hi-Lo tones.
AIR HORN Tone - Electronic AIR HORN sound.
Instant Public Address - Public Address override of all siren functions when the microphone Push-to-Talk key
is pressed.
Status LED - An indicator LED, visible on the front of the remote siren amplifier indicates that the unit is on
when lighted.
Radio Rebroadcast - Broadcast Two-way radio reception over siren speakers. These inputs are transformer
coupled to prevent loading of the radio.
Remote Siren Switching - The siren accepts either a positive or a ground (earth) signal, usually from the
vehicle's horn switch (or other user supplied switch), to remotely activate the MANUAL or AIR HORN functions.
(MANUAL or AIR HORN is selected via the slide switch located on the front panel of the siren amplifier. The
siren is factory set for a GND (Earth) signal and may be reconfigured to accept a positive signal. See
SETUP and Adjustments and Operation sections for details.
Noise Cancelling Microphone - Plug-in microphone that is easily unplugged for service or replacement.
