Sensor for escalators

Which escalators in Hong Kong, except those fitted in HKBU, are fitted with a sensor which stops the escalator when no one is using and re-activate the escalator when someone starts to use?

其實中環都有好多裝0左 sensor 0既扶手電梯，位置如下↓

1. 置地廣場畢打街入口，地下上一樓
2. 置地廣場二樓告羅士打大廈大堂旁，二樓落一樓
3. 遮打大廈全部扶手電梯
4. 歷山大廈全部扶手電梯

以上全部都係用迅達扶手電梯。
