En 50133 and fire alarms releasing access doors

[alonso]

Anyone got anything definite on en50133 and the need for fire alarms to release external doors? We used to have double pole green breakglasses inside and no link from the fire alarm to release external doors as it was judged a security risk. (Fire alarms could release internal doors only) We've been told that due to a new revision of en 50133 we now have to have fire alarms releasing the external doors. Anyone got an excerpt of en50133 I could quote from regarding this? A specific clause relating to this topic?
