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.
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!
Volatile Memory Issue!
Having said that I highly recommend installing the 555CLAM in what Autowatch call “Master Motor Mode” where possible. The 555CLAM has an issue where it can lose it’s programming memory if the battery is slowly discharged. It seems OK if the battery is disconnected when fully charged, but if left to go flat over a period of time the alarm programming is often reset.
Remote Boot Bypass
The 555 CLAM 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.
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.
Horrid emergency over-ride!
One of the weak points with the 555CLAM is the pin code over-ride. It requires turning the ignition on, then pressing the over-ride switch to start entering the code (see user manual for full details). The switch is ugly so it’s not realistic to place is in a nice location. I’ve seen some installers place them installed behind the glove box before now making it mission impossible to for the user should they ever need it! It really could have been better thought out.
The door inputs also need to be boosted with a relays on some cars to trigger the alarm. Whilst this is not a problem for the user it is annoying from an installers point of view.
RRP NZ: $570.00
Obsessive Rating: A versatile alarm which is very effective!
Would be great to see it come with a pager out-put, and the over-ride pin code needs a better design, but on the whole a good alarm so long as you don’t let your battery drain!
