Fire door latch replace with spring loaded ball catch

[Guest JohnLi]

I live in a Retirement Block of Flats in Sydenham London.
Our House manager recently replace the normal Latches of 4 of the 5 Fire Doors in our main stairwell with Ball Catches. Poorly fitted.
The only thing holding some of the doors closed is the Pressure of the Hydraulic closer. Neither Peverel or the London Fire Brigade see any fault with this. What can I do?
With thanks John

Only asking. What do YOU think is wrong with having ball catches and door closers on fire doors.

London Fire brigade are one of the the enforcing authorities for blocks of flats in London and if they accept the Ball Catches then there is not much you can do about it, other than go to the local housing authority who are to other enforcing authority.
