Ampire CAN3903V - Car alarm system for CAN bus (high-speed CAN)

Ordering information

This alarm system is delivered without software as standard. If you specify the car manufacturer, vehicle type and year of manufacture, we will load the appropriate software onto the alarm system free of charge and provide you with a connection diagram for the car.

You no longer have to do without a necessary alarm system in your vehicle due to the complexity of installation. The Ampire CAN bus alarm systems are armed via the vehicle's own CAN data bus of the comfort electronics and supplied with all alarm-specific

information, which means that installation costs are significantly lower than with conventional systems. In addition, the CAN bus alarm systems from Ampire also automatically control the indicators, central locking and comfort locking if the car supports this. Because in contrast to most cheaper CAN bus alarm systems on the market, Ampire CAN bus alarm systems can not only read information on the data bus, but also write commands.

Equipment

• Arming/disarming only with the original factory remote controls or comfort key
• No disarming by breaking into the door lock or trunk lock
• Flashing LED with integrated service button enables you to diagnose, operate and program
• Integrated 2-stage shock sensor with advance warning warns of break-ins or parking bumps
• No false alarms when the trunk is opened remotely or when the auxiliary heating or remote engine start is activated
• Emergency disarming and service mode possible at any time and safely in the event of a defect Radio remote control
• Includes high-current immobilizer relay for safe starter interruption

Alarm zones

The Ampire CAN bus alarm system optimally protects your vehicle via 6 separate alarm zones. With the "NPC" anti-false alarm function, individual zones are automatically skipped in the event of a malfunction. The long-term memory allows you to read out the two alarm zones that last triggered an alarm at any time.

• Alarm zone 1: triggered when the hood/trunk is opened (via CAN)
• Alarm zone 2: triggered by strong impacts via the integrated shock sensor (sensitivity adjustable)
• Alarm zone 3: triggered when the doors are opened (via CAN)
• Alarm zone 4: triggered by optional sensor (analog)
• Alarm zone 5: triggered when the ignition is switched on (via CAN)
• Alarm zone 6: triggered by optional alarm contact (analog)

Pre-warnings due to light impacts (via the integrated shock sensor) or by the optional sensor are not switched off as an alarm zone.

Engine compartment siren

This Ultra-compact siren with ferrite magnet is the best and loudest siren in our range. The siren has 6 different siren tones that are played one after the other and change every 5 seconds. All 6 siren tones can be switched off individually or the order can be changed. In addition, the volume of the siren chirp can be adjusted during arming and disarming using the "Soft Chirp" function.

• Sound pressure level (SPL): 121dB (1 meter distance)
• Magnet material: Ferrite
• Current consumption during alarm: 1200mA
• Number of different siren tones: adjustable 6 (different) or 1 (constant)
• Alarm duration: adjustable 30/60 seconds
• Volume of the siren chirp: adjustable ("quiet", "loud", and "off")
• Dimensions of the siren: 84x83x72mm

Outputs

• Immobilizer relay "FailSafe" included (15A load capacity)
• analog alarm output (200mA load capacity), for the vehicle horn or an optional GPS tracking system
• analog indicator/parking light output (200mA load capacity), if it cannot be controlled via the CAN
• analog AUX channel for controlling optional accessories (200mA load capacity), if the remote control lock button is pressed twice
• analog arm output (500mA load capacity), for controlling optional accessories

Note on the firmware

These CAN bus alarm systems are delivered without vehicle-specific firmware. Because the alarm systems can read and write on the data bus, the firmware is significantly more complex and must first be loaded using the XKLOADER2 or XKLOADER3 programming device. We can load the appropriate firmware for you free of charge. Please state the exact vehicle type and year of manufacture when ordering. It is also important whether the vehicle has comfort access (smart key). You can find further information and the latest firmware for your vehicle at: www.directechs.com in English. 

Settings

You can change the most important operating settings yourself using the service button integrated in the LED. This can be done more quickly and comprehensively using the optionally available "Bitwriter" programming device. It can simply be plugged into the serial "ESP" interface. This also allows you to enter a code into the alarm system or to lock the settings through manual access by third parties.

Legal notice

We recommend activating the siren sounds when arming/disarming (menu item 1-2). This means that you, as the user of the alarm system, receive acoustic messages about the status of the alarm system. You are informed by quiet siren sounds (siren chirping) whether the alarm system has been armed correctly. An acoustic error message (siren chirping) would immediately report an open door, manipulated alarm sensor, etc. However, this siren chirping is not permitted within the EU. The EU guidelines only allow a constant siren tone after a break-in lasting <30 seconds.

General technical data

• Operating voltage 12 Volt DC
• Quiescent current 14mA max.
• High speed CAN bus
• Alarm control panel dimensions 9.0 cm x 5.7cm x 3.2cm

E-approval

Thatcham insurance certification 

In combination with a 515M emergency power siren and a US509 interior sensor, this alarm system has been certified by Thatcham in the following classes:

• Vehicle category 2 classified as an alarm system in category 2-1
• Vehicle category 3 classified as an alarm system in category L2-1
• The certificates issued by Thatcham.org can be found under the "Download" tab.

Note on firmware upload 

Please only use Microsoft Internet Explorer with the XpressVIP 4.3 (ActiveX) software to upload the firmware to the CAN3903V alarm system. Other browsers are not automatically supported and errors may occur.

Installation notes

The optionally available MS508 radar sensor cannot be connected directly to the 4-pin sensor socket of the CAN3903V. The power consumption of the MS508 is too high for this. Connect the power lines of the MS508 directly to permanent plus and the "ground when armed" output.

Equipment notes 

Depending on the vehicle type and equipment, additional costs for installation, adaptations and data bus modules may arise if you want to control and remotely start the vehicle. The panic alarm or the AUX channel can only work if the vehicle supports the function.
