Abstract
A control or detection arrangement for escalators, moving walks and the like includes a detector, an encoder unit connected to the detector, a wireless transmitter connected to the encoder unit, a wireless receiver, a decoder unit connected to the wireless receiver, and a microprocessor connected to the decoder unit. When an unsafe condition is detected by the detector, the encoder unit generates a trigger signal having at least one unique identifier for the detector. When received, the signal is passed by the decoder to the microprocessor which causes generation of a command signal to, for example, stop motion of the escalator. Alternatively, the inventive arrangement operates according to continuous or periodic transmission modes, which permit the arrangement to monitor operability of the detector, encoder unit, transmitter, receiver and the decoder unit.
