Detection and Alarm

From the initial Fire Risk Assessment to the design and installation of the appropriate fire detection and suppression technologies, our range includes the most sophisticated detectors and alarms, through to fire extinguishers, fire suppression systems and other essential products such as signage and emergency lighting.

All companies in the UK must comply with the Regulatory Reform (Fire Safety) Order (RRO). Within the requirements it states that businesses should have a means of alerting a fire (fire alarm), a method of escaping from the fire (including fire escape and emergency lighting), and the ability to fight the fire (extinguishers).

It is also a legal requirement for all businesses regardless of their size to undertake a fire risk assessment which must be carried out by a competent person. This should be supported by a written fire safety procedure and training to ensure that staff can adequately use their fire extinguisher equipment.

DMI designs and installs complete fire systems with features such as:

  • heat and smoke detection

  • smoke beams

  • audio and visual warnings

  • air sampling and wire-free systems

  • automatic door and ventilation operations

  • flame detectors

  • intrinsically safe systems

  • together with remote monitoring and fire brigade signalling systems.

Our products range from traditional, standalone detectors and conventional fire detection systems to fully analogue addressable systems with networking capability which enables integration with existing security systems. To combine and simplify monitoring and detection processes all our products are open protocol.

Open protocol products are fully accessible and provide customers with freedom of ownership, and the freedom to choose any service provider for the ongoing maintenance of the system.

Auto Detection

The early detection at the start of a fire can make a significant difference to the outcome.


At DMI Group we partner with a selection of leading manufacturers including Gent, Hochiki and Apollo, each of which has been chosen by us to provide quality products that incorporate cutting edge technology.

Our team of experienced staff can help assess which system is most appropriate for your application, and offer unbiased advice to ensure that the system we install offers the best solution for both your current and on-going needs.

Our Fire Detection Products

  • Multi range detectors

  • High –sensitivity smoke detectors (HSSD)/ Aspirating

  • Flame detectors

  • Linear heat cable; digital, analogue, fibre

  • Video smoke detection

  • Gas Detectors

Public Address / Voice Alarm Systems

The benefits and uses of public address and voice alarm systems are self-evident.

Voice evacuation systems provide an effective solution to emergency crowd control, issuing clear unemotional yet compelling commands that help create a sense of calm and facilitate a quick, safe exit for people.

Our range of systems includes:

  • Stand alone and networked systems

  • Voice alarm integrated and/or combined fire systems

  • Integral within smoke detectors e.g. fire cryer and S- Quad

Aspirating Systems (Air Sampling Systems)

Air Sampling systems are specifically designed to detect fire at a very early stage and are often used in high risk environments such as data centres, document storage, museums and archive rooms.

These systems operate by sampling the air in a room by drawing the air through sample holes located in a network of pipes and passed through a high sensitivity laser detection device. This is an active detection system capable of detecting very small amounts of smoke and providing early warning of fire.

These systems are commonly used in conjunction with fire suppression systems …link to Gaseous and Fixed Extinguishing Systems

Although originally designed for high sensitivity detection, these devices are now commonly used to provide automatic detection in areas that are difficult to access or where discrete detection is required.

DMI Fire and Security are able to offer design, installation, commissioning and maintenance of these systems in line with BS5839-1 and FIA (Fire Industry Association) Code of Practice for Aspirating Smoke Detection systems.
