We provide fire alarm systems in Dublin and throughout Ireland
How Fire alarm systems work
Optical smoke Detectors:In some optical smoke detectors use a light beam which when blocked by smoke activate the alarm In others it is triggered by light scatter caused by the smoke. These are slightly less sensitive.
Ionisation Smoke Detectors Detectors:Ionization detectors have an ionization chamber and a source of ionizing radiation, this ionises the air in the detector. When smoke enters the ionization chamber, the smoke particles neutralise the ionised air and triggers the alarm. These detectors are very sensitive and when choosing a detector the building environment most be taken into consideration.
Rate of rise heat Detectors.Rate-of-Rise (ROR) heat detectors operate by detecting a rapid rise in temperature of 6.7° to 8.3°C increase per minute, irrespective of the starting temperature. When this rate is exceeded the alarm is activated..
Fixed heat detectorsThis is the most common type of heat detector. Fixed temperature detectors operate when the heat sensitive eutectic alloy reaches the eutectic point changing state from a solid to a liquid. The most common fixed temperature point for electrically connected heat detectors is 58°C. These detectors are often used in boiler rooms.
Break Glass unitsIf someone in your building sees a fire before it has reached a smoke detector or heat detector, they need to be able to let everyone in the building know immediately. Manual call points or "break glasses" enable them to signal the emergency simply by pressing the glass.
Fire BeamsReflected beam smoke detectors consist of a transceiver (a transmitter/receiver) unit that projects, monitors, and receives a beam reflected across the protected area. The detector works on the principle of light obscuration.
Fire DoorsMagnetic Smoke Door Holders: Wall or floor mounted solenoids or electromagnets controlled by a fire alarm system or detection component that magnetically secures spring-loaded self-closing smoke tight doors in the open position. Designed to de-magnetise and allow automatic closure of the door on command from the fire control.
Fire Alarm Control Panels:Fie control panels are the nerve centre of the fire alarm system. They are designed give an audible warning in the event of a fire detection device been activated. They can communicate with fire brigade if required utilising a digital communicator.
