If your Pyronix alarm siren's been acting up, it might just be the batteries.
This is a 2-pack of BATT-ES1 3V batteries specifically for the Pyronix Deltabell-WE MK 2 bell box.
They're brand new, in original packaging, and designed for outdoor use only – exactly what you need for external alarm systems.
Made by Pyronix themselves, so compatibility is spot on.
Each battery is 3V, and you get two in the pack.
EAN is 5056105601616 and MPN is BATT-ES1.
No extra items included besides the batteries – just pop 'em in and your siren's back to scaring off intruders.
Perfect for UK installations and built to last.
Don't wait until your alarm goes silent – grab these replacements and keep your security system loud and proud.
Simple, effective, and a whole lot cheaper than a new bell box.
