All fire systems installed by us are fully compliant with Irish and European Standards. We provide a large selection of fire alarm systems from all the leading makers of fire detection and control equipment. From the simple conventional device to advanced analogue addressable systems.
Lennon Group will be happy to talk you through the process, from planning through to installation, with all advice based on your individual and specific requirements.
Fire Panels are at the heart of any fire system
Every device links back to the panel and communicates with it. In addressable fire systems every single device can be interrogated and analyzed from the panel.
This is very useful when system tests and fault finding. Another advantaged of this type of system is that you can isolate specific devices rather than whole zones which will allow for phased evacuation procedures which are particularly useful in large buildings.
Also intelligent systems allow for phased evacuation procedures to be programmed into the system. Conventional systems are not as intelligent and can only see faults or fires in certain zones and not a specific area as with addressable systems.
Remote Terminals are also available which allow information to be distributed throughout a building. This is typically information from the main fire panel or specific information about the area the remote terminal is situated.
This is the point of contact with a fire. Detectors can either be used to detect smoke, heat or both. When there is a change in air particles (smoke) or heat in the local environment the detector will be triggered which then sends a signal to the panel indicating a fire. There are also Beam Detectors which detect smoke in large areas such as a warehouse and Flame Detectors which detect flames by analyzing the characteristics of flame movements.
Sounders and Beacons provide audio and visual indication that there is a fire.
Fire Alarm System Categories
There are many types of fire alarm systems each suited to different building types and applications. A fire alarm system can vary dramatically in both price and complexity, from a single panel with a detector and sounder in a small commercial property to an addressable fire alarm system in a multi-occupancy building. Systems have to protect both buildings and occupants. The categories of fire alarm systems are L if they are designed to protect life, P to protect buildings and M if they are manual systems.
