This reliable car alarm, which is easy to install, can protect your car and its contents against robbery. The alarm detects snap voltage drops of the battery, caused e.g. by the courtesy light or luggage boot light being switched on. To ensure the good working of the alarm, the kit is fitted with the following indicators:
- Flashing LED to indicate that the adjustable step out delay time has expired and that the alarm is armed. Moreover, this LED, when installed in such a way that it is visible from the outside, discourages potential burglars.
- Pre-alarm (built-in buzzer) to remind the user of the fact that the alarm is armed, so that he does not forget to switch it off.
The pre-alarm delay time is also adjustable.
The alarm can be switched on and off very easily, either automatically through the ignition lock or remote controlled by e.g. our infrared code locks VK6708 - VK6709, or the RF code lock VK6706B and VK6707.
The alarm has a relay output which can activate the horn or a separate siren continuously or in an intermittent way (selectable).
The alarm, after having been activated, will stop sounding after 60 seconds (statutory), whereupon it will rearm itself automatically.
- Detects voltage drops of the battery.
