Automatic fire detection originally started with “Conventional Systems”. This product line that seemed destined to disappear continues to find always new applications.
The heart of this system is a control panel with well-defined physical zones with generic alarms. The control panel identifies the macro area where the principle of fire developed. The Norms have then introduced construction rules that make it an extremely functional and simple system. There are very precise limits that define in detail the dimensions of the area (not more than 1600 m2) and the number of detectors (not more than 32 per zone). The buttons in the area must have a dedicated zone and must not be mixed with the detectors.
The application areas of a conventional system are small systems with large open areas and systems that use special products (barriers, flame detectors, intrinsically safe detectors) and/or extensions linked to wireless systems. Two other situations deserve a separate chapter: extinguishing systems and gas detection systems. Extinguishing systems are closely linked to conventional systems. The logic of the double configuration on 2 crossed zones, the instant extinguishing discharge activation, as well as the procedures related to attendance control in premises, closed doors, discharge lock, etc. are optimally managed by conventional control panels. These systems are often paired with analogue/addressable control panels to manage areas where protection with fire extinguishing is requested. Also gas leak detection, which in many case is composed of small systems with 3/4 detectors, is well managed by conventional systems. In the gas line there is a “AS” interface with current absorption, which is used to connect gas detectors to conventional control panels in a simple and economical way. Riellofire offers three models of control panels in accordance with EN54-2 ed EN54-4 with special features: the use of a single battery, the possibility to schedule the maintenance and adapt to any kind of detector.
