With its new generation of wireless detectors, Bosch Building Technologies
offers a flexible fire protection solution that works almost entirely without cabling. It is therefore ideally suited for historical buildings, for retrofitting and expansion of existing buildings, and for temporary installations. Thanks to the combination of two frequency bands and highly reliable mesh technology, the new wireless fire alarm system offers high system availability and maximum protection. The solution consists of a gateway, which is connected to the fire alarm system by cable, as well as up to 30 detectors and 10 manual call points, which communicate with the gateway by radio and can therefore be installed anywhere without cabling.
The new wireless solution from Bosch is highly scalable, as up to 10 gateways can be networked. They are compatible with every Bosch fire panel and can thus easily integrate into existing solutions. The gateways are battery-powered and can therefore be configured prior to installation, making commissioning much easier. Installation and configuration are intuitive and fast, and an intuitive diagnostic tool allows easy verification of the entire installation.
The detectors are arranged in a mesh topology instead of a conventional star topology. This ensures that redundant connection paths are always available to all devices, so that reliable alarming is ensured even if one radio link fails. Each detector acts as a repeater and can forward alarms from other detectors, so that radio-based fire detection can now be used even in very large buildings. No direct connection to the gateway is required for this.
The redundancy created through the mesh topology is complemented by the use of two radio bands to ensure reliable operation even in the event of interference on one frequency. In this case, switching takes place automatically. Both radio bands can be used without restrictions throughout Europe. The new wireless solution from Bosch uses EN54-certified multisensor detectors with optical and thermal sensors.
Main areas of application are hotels, town halls, shopping centers and temporary installations, for example in exhibition halls. Thanks to its redundant configuration, the radio-based solution is also suitable for challenging applications in which radio has often caused problems in the past, for example environments where many walls could interfere or block the radio signal.
