If the optional EN81-28 standard isn’t used for new lifts today:
There is no mandatory requirement for:
– being able to identify the calling lift remotely
– 72 hour / 3 day automatic test calls
– visual indication that the call has been answered
– visual indication of a failed alarm device in-car
– receive help by simply activating the alarm, no further action
– persistent alarm state until manually verified the lift is clear
– alarm filtering to reduce false calls
– bypass function for alarm filtering (hold button 30 seconds)
Some features will be available on many new lifts with factory fitted equipment, but often comprehensive features aren’t commissioned or regularly tested. The minimum standard of clause 28.2 of NZS4332:1997 is very minimal, and leaves a lot at risk compared to modern standards.
EN81-28 is an 18 page standard for remote alarms, but New Zealand requires not much more than an outdated clause to comply.
