Wireless bells for Borismaster

BMAC’s wireless bell push system is being deployed on the Wrightbus-built New Bus for London which enters service this month on route 38.

The wireless bell push uses no battery or wires, but instead uses a microchip radio transmitter. When a passenger presses the bell push, this action is converted into enough energy to transmit a signal to the receiver module, that in turn signals the stop sign and sounds the bell.

The signal generated by the transmitter is unique to each individual bell push, according to BMAC, ensuring that there is no cross-over interference between the other bell pushes on the bus or from other buses on the road. The receiver module is connected to the bus’ electrical system and the bell pushes are then fitted into place. Each bell push is then programmed to the receiver module to create, for example, four logical circuits - downstairs, upstairs, wheelchair and priority sitting.

“Threading up to 100 metres of cable to individual bell pushes on a bus, including all the machining to fit the bell pushes can be a lengthy operation,” says a BMAC’ spokesperson. “The wireless bell push removed a lot of this fitting time and the cost of all the cable helping to create a more efficient production line. Such a simple fitting also benefits the bus operator, speeding up the repair of faults and ensuring the bus is back on the road quickly.”
