For decades, conventional or four-wire fire alarm systems have been used extensively in smaller properties, such as shops and restaurants. This is primarily because four-wire fire alarm systems are less expensive to purchase than other types of alarm systems, which is always a bonus.
In terms of how they work, they divide the building into several 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, and a separate two-core, fire-protected cable for each alarm sounder or bell is required because 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 back to the control panel on the same set of two-core zone cables. This enables the fire alarm to use a single circuit per zone to detect and 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. This is made possible by the fire control panel receiving information and status reports from each device and indicating its exact location if there is a fire, fault, smoke, heat, or contamination.
Therefore, addressable, also known as “intelligent” fire alarm systems, are best used for large commercial premises and more complex networked systems.
The main downside is that they are significantly more expensive and complicated than conventional two or four-wire systems, but they do benefit from the following:
Today’s increasingly sophisticated, wireless fire alarm systems are more reliable than alarms that originated in the 1980s and are required to comply with EN54-25 standards. There are no cables between the detection devices and the control panel, eliminating the need for long-term cable tests.
Wireless or battery-powered radio-linked fire alarm systems are more expensive to buy but are:
