LPS 1673

About LPS 1673 and our tested and certified solutions

The recent increase in fast-moving, violent attacks targeting high-profile locations brought growing scrutiny towards physical security systems. Most importantly, their resistance against pre-planned and opportunistic forced entry attempts and marauding terrorist attacks.

LPS 1673 is LPCB's latest security standard, developed in collaboration with the National Protective Security Authority (NPSA), the National Counter Terrorism Security Office, and the US Bureau of Diplomatic Security. The standard is designed to assess resistance against fast-moving, violent attacks using brute force as well as bladed and blunt-impact weapons. Physical security solutions that achieve this standard can be installed to protect your safe spaces with confidence in their resistance against these types of attacks.

A selection of Tindall Engineering locking solutions has been tested and certified to meet LPS 1673. When combined with tested and certified doorsets, these locking systems provide robust protection for locations vulnerable to fast-moving, violent attacks.

The Rimlock and Modula are forced entry-resistant products already tested and certified to LPS 1175. Meeting the rigorous requirements of LPS 1673 has increased their flexibility for a broader range of applications, including designated safe places designed to protect people from harm.

MICO Rimlock

The Rimlock is a surface-mounted rim lock with an automatic deadlocking function that instantly secures the door upon closure. Its modular design, flexible entry device options and LPS 1673 certification make it suitable for both places of work and private residences.
