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!!!

Thatcham CAT 2-1* If fitted with ultrasonics
Obsessive Rating: A versatile alarm which is very effective!
Would be great to see it come with a pager out-put, but I guess you can’t have everything!

How do I turn off the annoying “chirps” when I arm/disarm the 555 CLAM?
Your local Autowatch dealer should be able to turn the chirps off for you.
Hi I have a ’09 Ford XR6, can you please suggest if 555 CLAM alarm be good for it or which one will provide more security to the car?
Thanks much!
If your Falcon is the New shape (FG Series) then the 695CAN would be my recommendation.
Cheers,
Julian
Thanks Julian, yes it is FG Series; Are you able to give me a quote??
Cheers!
Hi Munish,
I’ve just sent you an email with pricing for the 695CAN
Cheers
Hi, would this be a good alarm for an EVO7? I was considering the Mongoose MAP80 until I read your review…..
Hi Glenn,
Yes it would, but only if your Evo7 has a factory transponder immobiliser.
This post covers the details: http://vehiclesecurity.co.nz/blog/upgrade-alarms
Hi Julian, thanks for that… I will need to confirm. If not, what would be your recommendation for an alarm that also has at least 2-points of immobilisation?
That really depends on where you are located (the installer matters) and your requirements. Flick me an email (julian@vehiclesecurity.co.nz) and I can send you some options rather then go off subject here.
I am looking at putting an alarm in my 2000 Holden Commodore VT. Would this alarm be suitable for my vehicle?
Hi Bill,
The 555CLAM works fine in the Commodore VT.
