AC-DBX Dummy Siren (with Flashing LED) - Sync Alarm Accessory

The Yale AC-DBX Dummy Siren is a simple but very effective addition to any home security setup. It looks identical to a real siren once installed, with a solid build and convincing design that gives a clear impression of a working alarm system. The flashing LED adds an extra layer of realism, especially at night it’s bright enough to be noticed but not distracting. Installation is quick and straightforward, and it feels sturdy once mounted. It’s a great deterrent for anyone wanting to enhance security without the cost or complexity of a full system. Reliable, well made, and definitely worth it for the extra peace of mind.

A quality product that looks real with its intermittent strobe light. Good value and easy to fit.

Great dummy siren and also looks good when up

I ordered this as an addition to my existing Yale alarm system. It’s placed in a very prominent position on my house, because the main siren is positioned principally to be in good range of the hub. Visually it’s identical to a working siren. And when you open it up, you can see why - it’s the same mouldings, but with simpler electronics. It’s easy to fit and batteries were supplied (these are supposed to last 2 years). Maybe it’s a bit pricey, but it’s well made, works well and is indistinguishable from a functional siren.

Great deterrent. If you’ve ever been burgled , then you know how it feels….if not , good for you ….then get yourself organised and DETER ! Super easy to fit , identical to real alarm , terrific value . Buy two - front and back / side door / wherever it’s obvious to spot

Looks exactly like the real thing. There is a switch inside that turns off the flashing light if that's what you prefer.

Easy to install and very realistic

Couldn't be happier with this dummy alarm box. So easy to install and visually looks great. It's an excellent deterrent.

Looks nice Does not flash!
