Audio Tactile Pedestrian Detector Push-Button Assembly

Representing a major technology advance from ATS, this product, the audio tactile detector and push button assembly, is available with a selection of either audio only, tactile only, or audio plus tactile indication. The audio tactile facilities can be partnered with either the new ATS pedestrian push button assembly, or the CW45 series push button assembly, where uniformity at existing installations or visual wait sign indication is desired.

All pedestrian including those with sight or hearing impairments, are catered for with the ATS pedestrian detector and indication systems.They are powered by 240V but models to suit 110V, 48V and 42V are also available.

Audio Tactile Signals

The system produces two distinct types of audio signals and two distinct tactile pulse rates. The functions of these signals are:

1. The audible locating signal is continuously present for the duration of time the associated pedestrian traffic signal is in the Don't Walk condition. This serves to assist pedestrians with sight impairments to locate the push-button assembly thereby permitting use of both the audio and tactile indication facilities available.
2. The audible crossing signal comprises two tone audible signals, the first of which is a change tone which immediately peaks and then decays follows by a rapidly pulsing tone of a fixed frequency. This sequence ensures positive identification by pedestrians with sight impairments and also serves to enhance pedestrian walk indication to all pedestrian at the traffic signal installation.
3. During the Don't Walk condition, a tactile signal pulses at the same rate as the corresponding audio signal, thereby giving second sensory confirmation of the Don't Walk condition.
4. During the Walk (cross) interval, the tactile indication pulse rate operates coincident with the distintive audible Walk (cross) signal pulse rate.
