Product Description

Please note: This ionisation smoke alarm transmitter has now been replaced with the B1551 smoke alarm transmitter (insert link here). It has the same functionality however it now has a sleek square design. This transmitter is best suited for detecting explosive fires.

The B1550 smoke alarm transmitter has been upgraded and is now the B1551. The functionality is exactly the same however it looks different. The B1551 has a square, sleek new design. (Click here to be redirected to the B1551) When smoke is detected the smoke alarm will transmit a fire alarm signal to all receivers within its range, while giving out an audible sound like a normal smoke alarm.

We recommend that at least one smoke detector is placed on each level in a multi-storey house.
