A wired or hardwired Intruder Alarm system relies on wires running through your premises to send information back to the central control panel, triggering alarms or notifications when appropriate and notifying your security company if that is part of your service package.

Hard wired systems always perform well unless there's a system fault. However both systems perform as well as each other and have to in order to meet EN 50131 British Standards.


Wireless intruder alarms are one of the most efficient ways of securing your property. As their name suggests, there is no cabling or wires to run through the premises, allowing the system to be installed much quicker than wired intruder alarms.

If you need a new motion sensor in a flat roof extension, summer house or garage area etc., wireless wins hands down. Adding a new device to an existing wireless intruder alarm system is a very simple and clean job.

An alarm's Grade comes from the UK and European Standards on intruder alarms (described in BS EN 50131). It relates to an intruder alarm's ability to recognize genuine break-ins and avoid false burglar alarms. For each installation, the grade of the system has to be chosen according to various factors. In the EN the grade is described in terms of the type of intruder and how much effort they would put into a burglary.

There are four intruder alarm grades, which include:

  • Grade 1 Intruder Alarms

    Premises unlikely to be targeted by intruders. It is assumed that a thief is likely to be opportunistic rather than bothering to plan things. This is for domestic properties without insurance requirements for an alarm system.

  • Grade 2 Intruder Alarms

    Premises of a slightly higher risk of an intruder or theft due to valuables kept theft on site. In this case, the intruder is expected to have some knowledge of how alarm systems work and possibly carry tools to overcome a simple alarm system. This system would be for domestic and low risk commercial properties.

  • Grade 3 Intruder Alarms

    Premises at substantial risk from intruders due to high-value contents. The intruder is expected to have knowledge of how alarm systems work and have tools to overcome the system. This grade would be for high risk domestic properties and most commercial premises.

  • Grade 4 Intruder Alarms

    Premises have a very high risk of being targeted by organised criminals who have the knowledge and equipment to alter parts of the alarm system to prevent activation. The intruder will most likely not be working alone. A grade 4 system would be for extremely high-risk domestic and higher risk commercial properties.

Lone Worker Alarms

Lone worker alarm systems provide employees who work alone with a way to signal for help in an emergency. The alarm is usually triggered on a smartphone or device, and is sent to an external monitoring station, employer or emergency services. The alarm can come in many different forms including smartphones and wearable devices.

With different industries requiring slightly different approaches, there are many different alarms with alternative functions that help protect lone workers namely:

  • Duress Alarm – when workers are confronted with an attacker.
  • Man Down Alarm – the main use being when someone has collapsed or is experiencing a medical emergency.
  • Discreet Panic Alarm – sends an alert without an audible alarm in instances when a worker feels threatened and panicked but does not want to escalate the situation by initiating a loud alarm.
