Commercial Intruder Alarm Systems in Peterborough, Milton Keynes, Northampton, Nottingham, Leicester & surrounding areas

Intruder Alarms

Here at Swift Fire and Safety we design, install and maintain wired and wireless domestic and commercial intrusion and perimeter systems, all with remote monitoring and app capabilities.

With the increase in theft, vandalism and corporate sabotage a good security system effectively safeguards your asset, data and commercial property in wherever you are.

As much as you’d like to watch over your business 24 hours a day, it’s just not possible but an intruder alarm can. Swift’s state of the art systems can operate in single standalone businesses or multiple occupancy buildings with several businesses offering flexible setting and un-setting options.

Swift work with the leading manufacturers to ensure our system communicate with each other and with you, giving you complete peace of mind that we have your premises covered.

From 1st October 2005, New European Standards for Intruder Alarms replaced British Standard 4737. These apply to all Intruder Alarm Systems to be installed to Domestic and Commercial premises alike.


The System Design Proposal (previously ‘Specification’) is to be based on a Risk Assessment. One of the fundamental differences between the current British Standards and the new EN standards is the way in which systems are to be designed.

EN standards require system designs to be based on RISK.

To aid this, intruder alarm systems installed in buildings are graded. The grade of system (please refer to next section) will consider the:

  1. Risk level of the premises/house
  2. Risk level to the occupants (or householders)
  3. Contents value
  4. Typical knowledge intruders might be expected to have

The risk assessment is a fundamental part of the survey, this will form the basis of the System Design ‘Proposal’.

It is therefore essential that all the risks are considered and that the system (as designed) is therefore suitable and adequate to protect the particular risks.

Grading of Systems and Grading of Equipment

System grades (1-4) are categorised within the EN standard as:

  • Grade 1 – Low risk system where intruders are expected to have little knowledge of intruder alarm systems and be restricted to a limited range of easily available tools. (This standard is less than the previous BS4737 and it is expected that Grade 1 will not be acceptable to most Insurance Companies. e.g. certain devices are not required to be ‘tamper proof’)
  • Grade 2 – Low to medium risk system where intruders are expected to have a limited knowledge of intruder alarm systems and the use of a general range of tools and portable instruments.
  • Grade 3 – Medium to high-risk system where intruders are expected to be conversant with intruder alarm systems and have a comprehensive range of tools and portable electronic equipment.
  • Grade 4 – High-risk system where security takes precedence over all other factors. Intruders are expected to have the ability or recourse to plan an intrusion in detail and have a full range of equipment, including means of substitution and vital components in the intruder alarm system.

Additional Items

The equipment is now graded according to the level of protection built into the device, with Grade 1 being the lowest (least secure) security grade. Twelve hours of standby battery power is now mandatory (BS4737 was 8 hours). Control Panels are to have considerably more ‘reporting information’ e.g. for greater event recording and memory.

Environmental Classification of Equipment:

As well as the 4 security grades, the equipment now must conform to one of 4 environmental classes:
Class 1 – Indoor (even temperature) (e.g. office / living room)
Class 2 – Indoor General (e.g. garage)
Class 3 – Outdoor Sheltered
Class 4 – Outdoor General (open to the elements etc)
