    What’s new about BS 7273-4:2015+A1:2021?

    This is an amendment to BS 7273-4:2015 , prompted by research that identified the potential for confusion between red break glass call points and door release units on electronically locked doors, leading to unwanted alarms.

    The amendment:

• Supplies recommendations to resolve this issue
• Provides clarity on when a door may be secured with a panic bar, also known as a panic latch
• Makes it clear that in some circumstances, such as in care homes catering for residents who are living with dementia, the normal green break glass might, subject to a risk assessment, be omitted or subject to a variation in siting
