Intruder Alarms


Intruder AlarmWhether you are considering an Intruder Alarm System for insurance purposes, or simply for peace of mind, you need expert advice to assess the risk to your property and business and to specify the most cost effective, efficient and straightforward way to protect against intrusion.

Fidelity Integrated Systems are NACOSS Gold accredited and all systems that we design and install are fully certificated to the current European and British Standards; PD6662:2010 and BS8243. Such certification is mandatory if you require police response to your system.

If your insurers have stipulated that a system should be installed as a requirement of your policy, they would normally specify NACOSS Gold as their preferred option. At Fidelity, we can provide fully compliant system specifications which can be forwarded to your insurers for approval prior to any placement of order or works commencing.

Texecom platform and we have full remote diagnostic services available which means that in the majority of cases we can resolve minor issues from our offices without an engineer emergency callout being required, saving you both time and money. We are also taking the lead by implementing the new Emizon dual path signalling system that uses your existing ADSL connection and is backed up by the Vodafone network.

Modern Intruder Alarm Systems combine common building blocks, but these need to be located and programmed to suit your individual needs and office hours:

  1. A central control unit with full rechargeable battery back up
  2. One or more keypads to arm and administer the system
  3. A progammed entry and exit route to arm and disarm the system safely
  4. Intruder detection devices i.e. movement detectors or vibration sensors
  5. Local warning devices i.e. sounders and strobes
  6. A remote signalling device for central station alert

Remote System Monitoring

All of the systems we install can be remotely monitored at our central Alarm Receiving Centre (ARC). This can provide keyholder notification to your nominated staff or keyholding company, and if required the system can be certified to provide a police response to any confirmed intruder alarm activations.

There are numerous forms of signalling devices that can send a signal to a remote alarm monitoring centre. Historically these were of "single path" technology. As many insurers now require "dual path" technology, we now offer just two forms of tried and tested systems for simplicity. Dual path signalling, as the name suggests, provides two independent communication paths to the central station which provides an extremely robust and reliable solution. The two systems we offer are:

Red​care GSM

This system utilises the BT Redcare telephone network as its primary signalling path. This path is remotely monitored for faults or tampering so it is robust in it's own right. It is backed up, however, by a secondary path over the Vodafone cellular network. This forms the "Dual Path" signalling that insurers generally seek.


The Emizon system utilises your existing ADSL or broadband connection, so there is no need to have a separate telephone line installed with the associated installation and line rental costs. The connection is constantly monitored from our central station for faults and tampering, similar to the Redcare connection. Also, similar to Redcare, the Emzion utilises the Vodafone network for it secondary signalling path.

Like our CCTV and Access Control Systems, our Intruder Alarms can form part of an integrated systems solution to provide comprehensive coverage of your premises.

Based in South East London, we provide commercial businesses and residential estate managers from across Central London and the Home Counties with the finest bespoke security and fire system design, supply and installation. Many of our clients have Head offices in London, Kent, Essex, Hertfordshire, Buckinghamshire, Berkshire and Surrey with their systems integrated and networked across both the UK and the rest of Europe to their satellite offices and operational centres.
