L4V Van Alarm User Guide

You are protected by the L4V Van Alarm, the only Thatcham certified alarm dedicated to the LCV market. The L4V Van Alarm is programmed to interact seamlessly with your vehicle’s original remote and provides features that will add a new level of protection to the load area.

Arming and Disarming the Alarm

The alarm is programmed to use your vehicles original remote. This means when you lock and unlock your doors you will be arming and disarming the alarm at the same time.

Arming and disarming the alarm is signalled by and audible beep.

One beep for armed, 2 beeps for disarmed.

The system has a 30 second pre- arming period (arming delay) during which the LED is on steady. After 30 secs the LED will flash once per second to confirm the alarm is armed.

Disabling Internal Sensors

The alarm system can be armed without activating the internal sensors i.e., Wireless Infrared Sensors (PIR) (Load Area) or Ultrasonics (Cab Area) while keeping exterior perimeter protected (Anti-Peel / Anti-Tamper Sensors and Movement Sensors).

  1. Make sure the system is disarmed and ignition key is “OFF”.
  2. Insert the electronic key into its receptacle; the LED will give a quick flash
  3. Close vehicle doors and press the lock button on the vehicle original remote control
  4. System activation is confirmed by a beep and a flash of the turn indicators (if features are enabled)

Note → Sensor exclusion is bound to each single arming cycle.

LED / Alarm Trigger Diagnostics

This feature allows you to ascertain the reason why your alarm triggered and what part of the vehicle caused it.

If you return to your vehicle and the alarm has triggered, the system will give five beeps and five flashes of the turn indicators on disarm (Instead of the usual 2 beeps) this will indicate there has been an alarm trigger prior to disarming.

To identify the cause of the last alarm trigger, turn the ignition key “ON” and count the number of flashes of the red status LED installed on the dashboard; it will indicate the last alarm detected. Optical signals are repeated 3 times in a row; to interrupt, turn ignition key “OFF”.

The table below lists the various alarm causes and relative number of LED flashes…

LED FLASHES

LED OFF (2 seconds)      LED ON (1 seconds)

Note → Once the ignition key has been turned off, it will clear the alarm memory. Make sure you have identified the cause before doing so.

Emergency Override (Service Mode)

Service mode is for ‘’emergency disarming of the alarm’’ or ‘’total disarming of the alarm’’. To enter service mode:

  1. While the alarm is sounding you place the electronic touch key into the receptacle.
  2. Once you have done this, the siren will stop sounding. This confirms you have disabled the alarm and entered valet mode.
  3. To exit service mode and restore normal operation, touch the electronic touch key into its receptacle. A high-pitched beep and flash of the status LED will confirm that the system is back to normal mode.

Note → It is extremely important you only do this in an emergency.

PIR (Passive Infrared Sensors)

PIR sensors work by detecting infrared light given off by a moving object or person that emits heat. Positioned to give maximum protection and ready to trigger an alarm if anybody enters the load area.

  • To turn ‘’ON’’ your PIR, press and hold the button on the front → Release the button once the light comes on → It should flash 3 times. This means the PIR is now ‘’ON’’.
  • To Turn ‘’OFF’’ Your PIR – press and hold the button on the front → release the button once the light comes on → It should flash 2 times. This means the PIR is now ‘’OFF’’.
  • To check the PIR is working → press the button once, it should flash to show its on, if this doesn’t happen, follow above to ensure it is turned on. If it won’t turn on, then please replace the batteries.
MAINTENANCE→ The PIR takes 2 x CR2032 batteries, please ensure you check them periodically.

Anti-Peel / Anti-Tamper Sensors

Locks 4 Vans have designed and manufactured vehicle specific brackets for our electronic sensors to reduce the risk of the common ‘’Peel and steal’’ type attack (vehicle dependent).

  • To test the sensos make sure the system is disarmed → Ensure the magnet on the door is next to the electronic sensor on the bracket, slowly pull the door away from the sensor → the LED should light up for 1-2 secs.
  • If the sensor doesn’t light up, it either means the sensor and magnet were not in its tolerance range and / or the batteries in the electronic sensor are flat
MAINTENANCE→ Each sensor takes 1 x CR2032 battery, please ensure you check them periodically.
