Clifford Arrow 5.1

The Clifford Arrow 5.1 is a system that uses a dual stage shock sensor to trigger the alarm if it detects vibrations when the alarm is 'armed'. These systems are suitable as car or van alarms fitted when there is no need to provide a Thatcham system for Insurance compliance.

Arrow 5.1 supplied and fitted for £499* (see notes below)

Car Security Alarm System

Clifford authorised dealer logoThe Arrow 5.1 has some very useful and well thought-out features.

The device benefits from an amplified antenna, (like all Clifford products) and this means that you will be able to use the remote from a distance away, however this begins to wane if the remote battery needs replacing, or if there are obstacles in the line of sight.

This system also saves vehicle battery power by stepping down the LED status indicator flash. To save battery power 48h after the vehicle is armed the LED flash rate will slow to 50% and after 96h the LED will slow to 25% of the normal rate.

If the siren gives five quick chirps when disarmed then this indicates that the vehicle battery is low. We advise customers to firstly give their vehicle a good 'run' and secondly, if the fault persists, to get their battery performance checked at their local garage.

False Alarm Control Technology (FACT II) prevents annoying repetitive triggers from setting off the alarm, for example thunder or large passing vehicles. If the alarm triggers three times and the same sensor is making those triggers within 60 minutes of each other then, FACT II will ignore or bypass that sensor for 60 minutes. Should the bypassed sensor be triggered within the time-out period then the ignore period starts again for 60 minutes.

Additional Options

Please note there is only 1 auxiliary output so only one extra module can be added and all of these additional functions cost extra.


* Extra Parts and Labour will incur a reasonable additional charge as some vehicles require extra time for fitting e.g. Nissan Elgrand adds £80 to any alarm system, built motorhomes may need extra installation time, and door motor fitting is charged extra on a per door basis.
