🏭 Manufactured in Dorset, UK
We are the original designers and manufacturers of the twin flashing LED module fitted in this unit.
As a family-run security systems company established in 1993, we use these same modules in our own alarm installations.

Our bell box may cost a pound or two more, but no other seller includes a pre-fitted lithium battery with a true lifetime guarantee!

You won’t be climbing a ladder every 18 months to change batteries — ours are still flashing after over 10 years of service!

• Looks and performs just like a genuine Deltabell alarm

• Twin LEDs – not the cheaper single LED version

• Professional-grade, UK-assembled unit

• No wiring required – ready to install
