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.
