Bosch introduces click and go technology


Bosch says it is taking modular fire prevention systems a step further with its FPA-5000 panel.

It uses a bus system for standard plug in modules, employing what the company calls ‘click and go’ technology. It has no exposed circuit boards and using a hot plug principle, all system modules are automatically connected to the fire panel controller as they are inserted. The modules are encapsulated to make them robust and to protect them from electrostatic discharge. Even if the system is upgraded while it is in operation, the possibility of coming into contact with live components is extremely remote, says the company.

The most important component is the LSN module (Local Security Network) for installing detector and signalling appliance rings. A 2-wire cable is all that is required for an LSN loop/branch with 254 elements and it carries both power and data. Automatic and manual fire detectors, smoke extraction systems and signalling appliances are typical LSN elements.

Bosch modular fire detection technology is suitable both for large premises as well as smaller buildings such as country hotels and supermarkets. Even the entry-level version has an easy-to-use panel controller with an interactive touchscreen, and two module rails with six slots. This enables installers to configure a customised system containing up to 750 network components, while an expandable upgrade version is available for larger buildings. The basic version has ten slots and can be expanded in stages to 48 slots – sufficient for a network of up to 4064 detectors. The alarm output is initially displayed on a large touchscreen, the operation of which is described as intuitive and interactive.

A few spare standard modules are all that contractors need for planning, installation and ongoing maintenance, explains the company, so lowering spare part storage costs and installation time.
