Distributed Intelligence in the GSSnet

The ﬁ re detection control panel BCnet216 opens up ma- nifold possibilities for the realization of speciﬁ c requests of ﬁ re detection, especially in spacious buildings, high- rise buildings or wide-stretched areas.

The decentralized security network that has been crea- ted by BCnet216 offers increased security and reduces the total expenses due to a much lower cabling volume. The consistent ring-shaped cabling guarantees commu- nication between the sectional control panels even in the event of a line fault.

A sectional control panel of the BCnet216 is parame- terised as main operating unit for the administration of the GSSnet, all other members can be equipped with or without a display and operating unit.

The system is designed modularly and can be gradually expanded according to future demands. The maximum size of a BCnet216 comprises 127 network members, 9700 detector zones, 9700 actuations, 999 alarming devices, 99 transmitting devices as well as 199 logic sectors. Different interfaces are available for the con- nection of external information devices, e.g., a facility management system or a remote maintenance sys- tem.

Cabling of the detectors is required only between two neighboring sectional control panels. This clear and ﬂexible arrangement of the sectional control panel cre- ates a powerful network. In this way, most economical cabling and thus efﬁ cient use of the installation expen- ses is guaranteed. Larger distances between individual sectional control panels can be bridged through the use of optical ﬁ ber modems or long distance modems.

The entire virtual control panel BCnet216 provides for the monitoring in mid-sized and large systems, applying the same technology and the same software tools as with the single control panel BC216-1. This guarantees a minimum of training and expansion costs as well as expenses of the user and thus guarantees the optimal use of resources during the usable life of the building.

BCnet sectional control panels are available in wall mount cabinets, as 19“ compact version and in 19“ slide-in technology.

Extinguishing Control System

If required, the BCnet216 can be easily expanded to an extinguishing control panel LCnet216 according to EN 12094-1. The panel can control up to 127 ﬂooding zones in a maximum of 127 extinguishing systems.

The function of the extinguishing control panel is fully in- tegrated into the ﬁ re detection control panel BCnet216, a combined operation is therefore possible.

The LCnet216 is certiﬁ ed to EN 54-2, EN 54-4, EN 12094-1 and VdS as a pure extinguishing control panel and as a combined ﬁ re detection and extinguis- hing control panel.

Optionally, the LCnet216 can be implemented with full hardware redundancy.
