Medium Domestic and Low Commercial Risk
SR2 will provide an enhanced level of security over SR1 and is rated under the new rating of B3. This means it is rated for 3 minutes using conventional power tools. In conjunction with HVM and PAS rated products the likelihood of a intruder or unwanted visitor is greatly reduced. With added security features onsite, the security team can be informed of a potential break in within this 3 minute window.

Sites with a raised risk of a deliberate and persistent forced entry
SR3 is the highest current standard in the UK for a high security site, it is also rated as C5 (C being the tool grade and 5 indicating the minutes) using more substantial power tools and a gained entry time at a minimum of 5 minutes. This provides ample time for the other security measures in place to alert the site owners.
