button #2 followed by button #1 will arm or disarm the alarm without chirping.

l Audio Confirmation — Siren chirps once when armed, twice when disarmed, and

three times for zone override (such as a door is open when armed).

l Multi-use Remote Control — Transmitter button #2 can also be used to open or

close a garage door when used with the optional SEA910 receiver or control another
Uniden VS1100XR or VS2100XR.

l Alarm Status LED — The LED will indicate whether the alarm is armed (LED

flashes) or disarmed (LED is off), also which sensor was triggered.

l Unique Built-In Electromagnetic Shock Sensor (with pre-intrusion feature)

Revolutionary sensitivity-stable design ensures the sensor never needs readjusting
once it is installed. Constructed to eliminate contact problems associated with
corrosion, cold-soldering, and condensation. If there is a light shock to any part of
the vehicle, the siren will "chirp," but the alarm will not trigger. If a harder impact is
made to the vehicle, it will trigger the alarm and sound the siren.

l Complete Protection for the Car — The alarm triggers when:

1. A drop in current from the car's battery is sensed (e.g. when domelight comes
on).

2. Shock or impact to the car is sensed.

3. Any attempt is made to start the car engine when the alarm is armed (starter
sensing).

4. Any door of the car is opened.

l 115dB Siren — Will blast for 25 seconds upon intrusion and will reset automatically.
l Car's Door Lock/Unlock — Locks or unlocks the doors when the alarm is armed or

disarmed. (VS255XR only) Optional accessories may be required.

l Parking Lights and Car Locator — One flash for arming, two flashes for disarming,

3 flashes for tamper zone overridden and 4 flashes for tamper indicator. (VS255XR
only)

l Door Switch Input — Normally-open (N.O.) negative trigger input.
l Backup Battery Capability — Use a rechargeable 9V Nickel-Cadmium battery (not

included) to provide backup power to the alarm.

OWNERS MANUAL

ARMED

When button #1 is pressed, the siren chirps and parking lights flash once, and the LED starts flashing to
show the alarm is armed. (No lights flash for the VS235XR.)

ZONE BYPASS

When you press transmitter button #1 to arm the alarm, and the alarm responds with three chirps and three
light flashes (no flashes for the VS235XR), there are two possibilities:

A. Delayed domelights — If your domelights do not immediately turn OFF when you close your car door

(in other words, your vehicle has delayed domelights), it is normal to hear the three chirps. The alarm
should protect all the openings once the domelights go OFF.

B. A zone was bypassed — In other words, the alarm has armed, but a door may not be protected (either

because it is open, or because its pin switch is broken). If the bypassed door is later closed, it will be
restored.

If your alarm indicates a bypassed zone, find the cause as soon as possible to ensure your vehicle is
completely protected. For instance, if your driver's door is not properly closed when you arm your alarm, a
thief may be able to open any door without setting off the alarm.

NOTE — Make sure your car's domelight switch is not in the ON position when you arm your alarm. The
alarm may not arm properly if the domelight switch is left ON.

NOTE — There are references to opening or closing a door throughout this manual. "Door" also includes
your Boot or Bonnet, if they are protected. Ask your dealer.

NOTE — The chirps to confirm zone bypass will not sound if chirp delete is engaged. However, the parking
lights (VS255XR only) will still flash three times. (See CHIRP DELETE).

SENSOR BYPASS (Shock Sensor)

This is useful if you know, based on experience, that your shock sensor will false trigger, such as when you
park near a construction site.

Should you wish to bypass your alarm's shock sensor, first press button #1 to arm the alarm. The siren
chirps and the parking lights flash once (three times if a zone is bypassed) (no flash for the VS235XR) to
confirm armed. Within three seconds, press button #2. The siren chirps three times and the parking lights
flash three times (no flash for the VS235XR) to confirm shock sensor is bypassed. The sensors are
automatically restored the next time button #1 is pressed.

NOTE — The chirps to confirm zone bypass will not sound if chirp delete is engaged. However, the parking
lights (VS255XR only) will still flash three times. (See CHIRP DELETE).

DISARMING

Press transmitter button #1. You will hear two chirps. The red LED will stop flashing. The parking lights
will flash twice, at the same time the car doors will be unlocked (VS255XR only). The alarm is now
completely disarmed.

EMERGENCY DISARM

If you lose your transmitter, you can disarm your alarm with the ignition key switch. While your alarm is
either armed or triggered, turn the ignition switch ON/OFF 4 times within 15 seconds. The siren and the
flashing lights stop if the alarm was triggered, and then chirp and flash three times. The alarm is now in
valet (see VALET). (No lights flash for the VS235XR.)

EMERGENCY CALL FOR HELP (panic)

To trigger the alarm in an emergency, press and hold transmitter button #1 for 3 seconds. The siren
sounds and the parking lights flash for about 30 seconds. Stop the siren and the parking lights any time by
pressing button #1 again. (No lights flash for the VS235XR.)

If the alarm was disarmed when you triggered the emergency call for help, the alarm immediately arms and
the doors lock. If the alarm was armed, the opposite will occur.

TOTAL PROTECTION

While your alarm is armed, your car is protected in the following ways:

l Potential thieves or vandals should be deterred by the flashing LED.
l If anyone opens a door, the alarm will immediately sound the siren and flash the parking lights

(VS255XR only) for 30 seconds, after which the alarm will rearm, bypassing any open doors.

l Turning the ignition key ON will trigger the alarm for 30 seconds.
l The optional Engine Immobilizer prevents the car from being started.
l If the shock sensor detects light taps on the car, it will trigger the pre-intrusion alert (the siren chirps

three times, and the parking lights flash three times [lights flash for VS255XR only]) to warn potential
thieves and vandals. However, if the shock sensor detects a strong shock to the car, such as shock
caused by prying the Boot open, it will trigger the alarm for 30 seconds. (See DUAL-STAGE SHOCK
SENSOR.)

CHIRP DELETE (silent arm/disarm)

There are times, especially at night, when you may not want to hear the siren chirps.
Just press button #2 any time before you need the chirps deleted. For instance, press button #2 before

you press button #1 to arm or disarm the alarm, and the chirps will not sound, but the parking lights will still
flash (lights flash for VS255XR only). The chirps are restored the next time you press a transmitter button.

NOTE — This function deletes the chirps for disarm, zone bypass, sensor bypass, valet, and tamper.
However, it does not affect the flashing parking lights. (VS255XR only)

VALET

Sometimes you may not wish to arm your alarm when you leave your vehicle. (For instance, if you leave
your car with a valet attendant, you may not want to teach him how the alarm operates.)

To enter valet, first disarm the alarm and turn the ignition ON/OFF 4 times within 15 seconds. The alarm
is now in the valet mode. The siren chirps and the parking lights flash once to confirm (lights flash for
VS255XR only). Your alarm also goes into valet when you use emergency disarm. (See EMERGENCY
DISARM).

To exit valet, just turn the ignition ON/OFF 4 times within 15 seconds. The siren chirps twice and the
parking lights flash twice (lights flash for VS255XR only) to confirm valet is exited and the alarm is
disarmed.

If you press transmitter button #1 while the alarm is in valet, the alarm will not arm but the doors will lock
or unlock, and the parking lights will flash four times (VS255XR only). The alarm's emergency call for
help operates normally.

DUAL-STAGE SHOCK SENSOR

Your alarm includes a patented dual-stage shock sensor.
The first stage (pre-intrusion alert) warns thieves the alarm is armed. For instance, the alarm will chirp

three times and the parking lights will flash three times (lights flash for the VS255XR only) if the sensor
detects a light bump to the vehicle. However, if the thief attacks the car with sufficient force, the alarm will
trigger.

Your dealer can make the shock sensor more or less sensitive to attack, depending on your vehicle.

POWER DOOR LOCKS (VS255XR only)

With this optional feature, your alarm can automatically lock the doors when armed and unlock the doors
when disarmed. The doors lock and unlock any time transmitter button #1 is pressed (exception — See
EMERGENCY CALL FOR HELP ). For extra security, they lock automatically if the alarm is triggered.
Extra accessories may be required, i.e. SEA169 Interface, SEA170 Door Motor.

ENGINE IMMOBILIZER SEA865

With this optional feature, while your alarm is armed, your car will not start.

TAMPER INDICATOR

If your alarm was triggered when you were away, the siren will chirp four times and the parking lights flash
four times, then turn ON for 6 seconds when you disarm your alarm.
These "memory" flashes automatically reset when the ignition is turned ON.

OPTIONAL BACKUP BATTERY

With main power disconnected, the backup battery will normally last for at least 24 hours, assuming the
alarm was not triggered. If triggered continuously, it would last for approximately 6 minutes. A 9V
rechargeable Nickel-Cadmium battery must be used. The alarm will recharge the battery automatically.

CODE LEARNING

The alarm can learn a maximum of 4 remotes. RF CodeWash™ deletes all previous remotes when any
new remote is learned. This prevents unauthorized use of lost or stolen transmitters, and alerts the user if
someone has secretly code- learned a new transmitter. However, it also means that, when code-learning
is being done, ALL THE USER'S TRANSMITTERS MUST BE CODE LEARNED AT THE SAME TIME.
