    Just to clarify AFAIK / IIRC, the detection range is calibrated and set to say just several centimetres (about half an arm length or so). You'll have to literally be shoving your face almost up to the door for the interlocks to be triggered thus preventing people just standing around in the elevator lobby and away at a safe distance from obstructing with the operation.

    In fact, if you checked out the Mitsubishi Electric (Elevators & Escalators): "Hall Motion Sensor (HMS)" link earlier. it is specified that detection diameter underneath the Infrared (IR) sensor at a height of - 1000mm (100cm) and - 2000mm (200cm) is 130mm (13cm) and 250mm (25cm) respectively.

    I checked out the below diagram....



    Did not really indicate how far the sensor reach from the door.... but I suppose everything is adjustable.....

    I wondering if it is 2 phase detection? The 2000mm is first actuated and when the 1000mm pick up motion and actuated, the door will re-open??

    But sensor failure is not uncommon, and sensors can be fooled... some sensor will go haywire, and be affected by the working environment, especially if there's strong lighting....

    and sometimes the lift take a bit of time to react to re-open the doors because people love to rush in when the doors are closing.

    the sensors only work at 100% effectiveness when the doors are wide-open and people are walking in and out. not when they're closing. if you don't believe, try rushing in when the doors are about to close
    There is a simple solution to this.

    All owners and dogs should not be allowed to use lifts.

    They should use the fire escape. Walking up and down the stairs is good for the owners and the pets.

    Well, this could easily derail into something very .. controversial.. (at its best).

    ya lah, the seemingly safe everyday act of posting in KPT can become fatal, if people starts to behave this way. LOL

    Diagram probably just showing a lateral (X axis) / vertical (Y axis) zone of coverage within the protective area, any obstruction at this specified space will either open the closing doors or stop the doors from closing in the first place just like the Infrared (IR) approach sensor for an automatic sliding door.

    Almost all HDB Apartments are equipped with Lift Telemonitoring System (TMS) linked to a centralized master control and monitoring station, faulty sensors will trigger a systematic red flag and be tagged as inoperative with the property management services provider being notified remotely.

    You can't have a safe "everyday affair". Sure to turn fatal.

    Lifts have become part of our life especially in Singapore. It is timely they start working on improving the door sensor. Modern advanced building lift's door sensor is a complete row not single photo cell. Don't wait till a human accident before the authorities act.

    Life is getting very UNSAFE!!.
    Taking the MRT is also a everyday affair. Lets hope that the train will not derail and crashes onto the road below.
