The 555 CLAM is an upgrade alarm from Autowatch, it features the same battery back-up siren found on the 446RLi Premium and also has a small attack proof security housing.
As with all upgrade alarms the 555 CLAM is designed to operate from using your factory remote control (read the Upgrade Alarm Introduction post for a better understanding).
The Autowatch comes with a glass break sensor as standard (in New Zealand) but this can be changed depending on your requirements. In Europe the 555 CLAM comes with Ultrasonics and is approved as a Thatcham CAT 2-1 upgrade alarm.
Intelligent alarm!
The 555 CLAM is intelligent, where lesser upgrade alarms simply monitor the signal wires to arm and dis-arm (see Mongoose and Dynatron in the coming weeks) the Autowatch can actually learns the timing sequence. This makes it a great alarm for any competent installer and if fitted correctly makes it impossible to trick into disarming by sly methods!
The 555 CLAM also has a boot sense wire which means that if your factory remote has a boot open button then the Autowatch will disarm the boot and the internal sensor when it is pressed (leaving the main doors still armed), then fully re-arm upon shutting the boot.
Other Features
The key guard feature (Note: it is only an option) is a nice idea on paper. It involves having to press a hidden switch every time you start the car, in reality this is going to become annoying and will end up being turned off! Cobras Drivers card is a far more sophisticated way of guarding your keys against theft.
Intelligent…. Just wait until the “Dumb alarm” review!!!

Would be great to see it come with a pager out-put, but I guess you can’t have everything!
