Tampines Mall - (Lift Lobby B Tour on Levels 5, 6, 7) Refurbished OTIS 3200 Elevators

UPDATE : The 5th floor is used as a pathway to the projection rooms for the Cinema.
Welp, this concludes the tour of levels 5, 6, 7 and even 8 (Rooftop). Levels 5 and 6 are relatively easy to access while level 7 is locked which houses Capitaland Management Office. Unfortunately, the 3200 buttons had been wiped out of trace after the refurbishment.
If you are wondering how I accessed the staircase, level 4's staircase doors are unlocked.
Details :
Level 5
Its an empty lobby that serves only the Fireman Lift which the one beside it dont for some reason. There is a keypad locked door when you turn to the right which leads to an unknown place (Probably the GV Office or something). The segmented part of the indicator is no longer working except the up and down lanterns.
Level 6 :
This lobby serve the exit way of the cinema which imo is one of the well preserved lobbies in the mall except the buttons. The Fireman Lift segmented indicator does not work while the one beside it works perfectly fine.
Level 7 :
This lobby serves the mall's management office on the right when you exit the lift and the indicator looks like its messed up.
Rooftop Level :
This serves the motor room of the lifts which I unfortunately can't access currently. The malls diagram shows how it looks through the door.

By right it supposed to be locked but the 4th Floor door knob was broken so I easily went in there
