Cobra AB7928

The Cobra AB7928 has been around for a good 10 years now, but despite its age has features which are sadly lacking from most of the rival brands here in New Zealand. Ultrasonics come as standard along with a digital battery back-up siren.

One of the strongest points with the AB7928 is the immobiliser housing which is a sealed attack proof unit that is connected to the main alarm module via a digital data wire. This means that even if it is located it is not possible to simply undo the screws and pop it open and by-pass the Immobiliser cuts.

The larger button arms/disarms the alarm and the second button will turn off the ultrasonic sensors and additional sensors and act as a panic button.

One odd thing with the AB7928 is that there are no arm/disarm chirps so you have to look for the indicator flash to confirm. This can be quite annoying at times.

The remote controls, despite the odd appearance are very rugged and have certainly passed the test of time, they are also great to use in the dark as the main button has a nipple in the centre making it easy to locate with your thumb.

Over-ride Touch Key

Cobra seem to have over done the over-ride options on this model as the alarm not only has an additional touch key (in-case the remote ever fails) as well as a 4 digit pin number. Personally I wouldn’t want the over-ride touch key cluttering up my key-ring but it is certainly easier than having to use a pin number.

The one thing that is missing is a pager output but on the whole this remains a solid alarm.

Note: Both a working Touch Key, and the 4 digit pin code are required to program a new remote.
