EM24EX Self-Resetting Emergency Exit System
SECURED BY DESIGN, NEW HOMES 2014:
24.11 Break glass emergency door exit release devices (often green in colour) on communal external doors that give access into the building are not permitted due to constant abuse.
Instead, vandal resistant stainless steel self‑resetting emergency exit systems are to be installed.
The installation and system type must be in full compliance and achieve final ‘sign-off’ by local Building Control.
