Jaycar Large 12V Piezo Tweety Pie Siren – 119dB, Low Current Draw 250mA

You need a siren that actually gets heard over the traffic on the main road, not one that pings politely like a microwave. This is the big-brother Tweety Pie. 119 decibels of piezo scream, and it only pulls 250mA from your 12V supply — so it won't drag down your battery or trip your fuse. It's bigger than the small Tweety Pie but still a fraction the size of a full alarm siren. If you've got a shed, a van, or a workshop where you need to be heard without running a 40-amp circuit, this is the one. Plug it in, trigger it, and the whole street knows something's up

• 119dB piezo output — loud enough to cut through traffic and workshop noise
• Only 250mA draw at 12V — gentle on batteries and low-current power supplies
• Larger than the standard Tweety Pie but far smaller than full alarm sirens
• Piezo design means no moving parts to wear out or fail
