Hi folks not sure if this is the right location to post this so apologies if its not.
I was talking to another electrician the other day about intruder alarms and i was under the impression that it was regulation to have the tamper working on the inertia sensors on the likes of windows etc. he claimed its not regulation any more that it changed arouind a year ago.
Can anyone confirm this please as i found it hard to believe that regulations would take a step backwards when it comes to safety/security
Thanks in advance for any replies.

The standards are now graded. If its certified as Grade 1 . then tampers are optional.
For Grade 2 on they are mandatory.

hi koolkid thanks for the reply
but i dont really understand the grades.
what i mean is would a 3 bedroom house consist of a grade 1 or grade 2?

It is based on risk.

• Grade 1 - low risk
• Grade 2 - low to medium risk
• Grade 3 - medium to high risk
• Grade 4 - high risk

For a Grade 1 system intruders are expected to have little knowledge of intruder alarm systems and be limited to a range of easily available tools.

A Grade 2 system expects intruders to have a limited knowledge of intruder alarm systems and the use of a general range of tools.

A Grade 3 system expects intruders to be conversant with intruder alarm systems and have access to a comprehensive range of tools.

Finally, a Grade 4 system is where security takes precedence over all other factors. At this level intruders are expected to have the ability and resources to plan an intrusion in detail and have a full range of specialised equipment, including means of substitution of vital components within the intruder alarm system. As you can see systems are evaluated against the risk of the level of intruder that may attack the system hence the requirement that system design meets the appropriate grade.

The will be defined by a security surveyor, customer or insurers. It is most likely that insurers will specify systems at Grades 3 and 4.

This would by my version of grading 10

Grading all depends on risk and for each grade there is suitably graded equipment to match. The grade of a system is defined by the lowest graded component so don't go and install all grade 2 equipment and put a cheap grade 1 contact on the front door

Grade 1 - Don't even go there. As pointed out no tampers and equipment that is grade 1 is usually very cheap

Grade 2 - 99.5% of my installs are grade 2, most of the hkc europlex etc is grade 2. This will cover domestic and a lot of commercial
Good practice would be to work to grade 2 and no lower

Grade 3 - High end financial and some domestic. I only have a have a few of these. All equipment will have to be grade 3 ie the panel will have more battery capacity, will consist of anti masking PIRS, anti biasing contacts etc
Chances are that you will never have to worry about this

Grade 4 - I have yet to see any. I will keep an eye out at IFSEC for some, but I am open to correction here, it may not even exist yet
