Keeping your commercial or residential rental property safe and protected against fire damage is vital. At Assured Electrical Solutions, we strive to provide exceptional service in Cardiff and across Wales through our use of cutting-edge technology.
Designed to rapidly detect fires and minimise the damage and disruption caused to your business, our fire alarm systems provide you with the peace of mind you need as a property owner.
Fire is a serious risk to any business or private landlord, and it’s your responsibility to ensure your premises have an effective fire detection system installed. If you fail to install and maintain a fire alarm system, you could be putting your entire business or tenants at risk should the worst happen.
Conventional or four-wire fire alarm systems have been used extensively in smaller properties, such as shops and restaurants, for decades. Four-wire fire alarm systems are less expensive to purchase than other types of alarm systems. They work by dividing the building into a number of detection zones, with the detectors and call points within each zone hardwired on dedicated circuits to the control panel. There may be multiple detectors in a single zone. A separate two-core, fire-protected cable for each alarm sounder or bell is required due to the fact they are wired to different loops. If a detector is activated:
Predominately designed for smaller properties, two-wire fire alarm systems are based on standard conventional system technology.
The two-wire system, the detectors, call points and alarm devices for each zone are wired on the same set of two-core zone cables back to the control panel. This enables the fire alarm to use a single circuit per zone both for detection and to power the sounders or sirens.
Although two-wire systems are more expensive to purchase than four-wire systems, they are quicker, more flexible, and less expensive for our installers to put in place.
Two-wire systems also provide more flexibility in operation, and have additional functionality, including:
Analogue-addressable fire alarm systems provide details on individual detectors, whereas conventional systems only provide information about specific circuits or zones.
Addressable, also known as “intelligent” fire alarm systems are designed for large commercial premises and more complex networked systems.
They are significantly more expensive and complicated than conventional two or four-wire systems in that they have:
The fire control panel receives information and status reports from each device and indicates its exact location if there is a fire, fault, smoke, heat, or contamination.
Wireless or battery-powered radio-linked fire alarm systems are more expensive to buy but are:
There are no cables between the detection devices and the control panel, eliminating the need for long-term cable tests.
Increasingly sophisticated, wireless fire alarm systems today are more reliable than alarms that originated in the 1980s and are required to comply with EN54-25 standards.
They have multi-frequency links to eliminate signal blocking and collision, allowing a high margin of signal strength to be maintained.
