Hi folks
I clean the stairwell windows on 6 blocks of new build flats, most of the windows turn in but there are 5 windows that are fire escape doors that open automaticly only if if the smoke alarm or firealarm is set off and i have to get the ladder off to clean these trad

I cant use my wfp as the windows have railings covering the lower half and is too much hassle messing about trying to get the brush between the railings So.....
Does anyone know how i can get the doors open ( without setting a small fire in the stairwells )

Is there an override switch in the utility room or something?

?
