It is necessary to consider the local regulations and related standards while designing the fire detection and alarm system. In accordance with the principle of design and application made according to the standards, more than one fire alarm control panel can be used in the system. Depending on the structure of the facility, the layout of the buildings and the scenario, the fire alarm panels may need to communicate with each other.
In general, the distances between the fire alarm control panels are excessive in the campuses with distributed structures. Copper network lines allow maximum transmission distances of 1200m. Fiber optic network lines are used for the points above these distances. It is possible for the panels to communicate with fiber cabling up to 40km. In addition, fiber networks are preferred at distances below 1200m due to their more stable structure than the copper network in the external environment.
There are MM (Multi Mode) or SM (Single Mode) cabling options depending on the distances between the fire alarm panels. Although it varies depending on the characteristics of the fiber optic converters to be used, it is possible for the panels to communicate with each other through Multi Mode fiber network lines between 1.2-2.4 km and Single Mode fiber network lines between 2.4-40 km.
How Often Should I Have My Fire Detection Systems Serviced? »
The most important issue for fire alarm systems is that all equipment used complies with the standards and is certified. This point should not be overlooked while selecting a product. The fiber optic converters which are produced or tested by the manufacturers and which are of the brand/model recommended by the manufacturers should be used. End-to-end proper design and appropriate product selection are important for the fire alarm system, which is a life safety system.
