Trailer Alarm

Whilst the bulk of my work tends to be on cars, vans and such like, my golden rule of thumb is that if it has a 12 volt power supply (or 24 volt) then I’m happy to install an alarm in it.

This leads me nicely into introducing one of the more interesting installs I’ve done recently. A massive trailer that I got involved with about 8 months ago when Tom (the owner and an exiting customer) informed me that he was about to build a new trailer for his chimney cake business. He would be making it from scratch and wanted my input into the best way to install an alarm.

Anyway 8 months later I had the pleasure of seeing the finished beast (alarm and all) when I caught up with Tom at the Left Bank market off Cuba Street. I’m am in absolute awe of the machine he has made.

The Construction…

Most people simply would not have the ambition to take on such a huge project. The fact that Tom was driven (and crazy) enough to take it on speaks volumes about the man. The attention to detail is incredible. What makes it even more remarkable is that this is the first trailer Tom has ever made.

Anyway, it was great that Tom asked for my input at an early stage. It’s quite rare for someone to consider where I would need to run cables and such like but once Tom explained how the trailer would operate I began to understand why I needed to be involved so early.

The upper section of the trailer would lift up pneumatically so that there would be enough head room to work inside, then drop down to about half the height to make towing easier. This would mean that the electrics in the upper section needed to be planned so that there were enough cables, as adding them at a later date would not be an option.

It would be made so that it could be towed from either end to make it easier to maneuver.

On top of that it would also have the wheels fold down underneath the frame when not being towed.

The trailer would be lit by LED strips which would draw less power then conventional bulbs so I decided that it would be a nice touch if they could be turned on and off with the alarms remote control. It would also be wired so that the red park lights and white navigation lights would light up on the right end of the trailer regardless of which end he plugged the tow bar electrics in.  Tom asked if the alarm could flash them so I wired them up to flash alternately when the alarm was triggered.

The Alarm

We decided that the Steal Shield SS450 would be the prefect alarm for what was required. It has a simple 4 button remote.

Lock – Arm
Unlock – Disarm
* – Lights on (Aux out)
# – Optional second alarm control

Note: Extended press of the unlock button turns external lights off.

So apart from being a user friendly toy, the alarm was wired with switches on all hatch opening, a couple of sirens (one is never enough in my world), as well as a internal movement sensor.

The other useful feature with the SS450 is that the LED will stay on when any door is open. This makes it easy to check that all hatches on the trailer are shut.

Finally I can’t finish without mentioning the chimney cakes. They are bloody fantastic and I urge everyone who reads this to head on down to one of the markets and try one whilst checking out Tom’s trailer.

You’ll normally find him down the Te Papa market on Sundays and from what I’ve seen there is normally a long line of people waiting which simply goes to show how good they are 🙂
