The SS450 is a quirky little alarm that comes with a 4 button multi-function remote that can operate two cars. It’s incredibly small which is never a bad thing. In fact, it’s so small that I actually managed to install one into a lego car some years ago!
It’s also a very versatile alarm so is good for some of the more customised installs.
Good Remote Controls
The remote is sensible in that it has a lock, unlock, * and # buttons.
The lock and unlock do exactly what they say, but can also be programmed for double locking, for a car that has deadlocks, and selective unlocking.
An extended press of the unlock button functions as a boot pop, and the * button works as a programmable AUX output. This leaves the # button which when pressed first works for car number 2.

Now it does have some flaws that can be irritating. The Blue LED never truly turns off which can be a pain whilst driving at night! Personally, I like to change the LED to a red one so it is not so much of a distraction.
The LED also comes on when a door is opened which could be useful for the rare car that does to have this already!
There is a built-in impact sensor on the SS450 that can be adjusted with the remote control, the only other alarm I can think of that offers this is the Autowatch 279RL.

Obsessive Rating:
Despite having some annoyances it can be a good alarm and toy!
Sure it’s no Viper, but then it does not have that Viper price tag!
