for false fire alarms. The fire detection control panel BC216-1, besides automatic adjusting of the sen-
sitivity of the detectors, is capable of displaying a
dirt message
on the control panel before the detec-
tors activate false alarms due to dirt, by using ADM-, ADMPRO- as well as addressable conventional
technology.
The control panel is capable of making a
forecast
for each detector about the time of the next cleaning
by analyzing the measured values provided by the automatic detectors of ADMPRO- and
ADM-technology.
2.3.2 Fire detection control panel BCnet216 (network control panel)
The network fire detection control panel BCnet216 (consisting of BCnet sectional control panels
BC216-2 and BC216-3) is designed to be used in a modern fire detection system of medium to very
large size as a receiving and controlling unit. Due to its compact modular construction of the single
BCnet sectional control panels and its flexibility in the setting of parameters, it can be very easily
adapted to different demands and thus generally can be used in a large variety of circumstances. The
control panel sets new standards for the security in the fire alarm technology while reducing the costs
due to the simplicity of cabling.
The listed features from page 17 in Chapter 2.3.1: "Fire detection control panel BC216-1 (stand-alone)"
of the stand-alone control panel are valid also for
every BCnet sectional control panel
of the network
control panel BCnet216.
The
operation
of the whole network control panel BCnet216 is made via the display and operating
units of one or more BCnet sectional control panels or via remote display and operating units in the
same way as the operation of a compact control panel. The user will not recognize that in reality the
control panel consists of several components which are spread over a wide range of space.
Display and operating units of BCnet sectional control panels or remote display and operating units can
also be configured as
sectional display and operating units
for displaying and operating area parts of
the whole system, depending on the requirements.
The network is constructed
circularly and redundant.
In case of a line fault of the network through
wire breakage or short circuit all BCnet sectional control panels and other GSSnet members keep work-
ing uneffectedly. Even in case of multiple faults of the network cabling all GSSnet members keep
working, but in this case displaying and operating is probably only possible directly on the BCnet sec-
tional control panels and limited to the corresponding surveillance area. Optionally the activation of a
transmitting device can be constructed so that even with a double fault in the network cabling no im-
pairing of the function occurs. Connection of the BCnet sectional control panels to the network is made
by one of the serial interfaces built into the sectional control panels.
Up to
127 GSSnet members
(i.e. BCnet partial control panels, remote display and operating units,
gateways, etc.) can be connected to the network. The line length between two neighbouring GSSnet
members may be up to 1200m, for larger distances
repeaters
can be interposed.
Up to 9699 detector zones, 9699 actuations, 99 transmitting devices and 99 alarming devices can be
managed in a network fire detection control panel BCnet216.
2.4 Peripheral devices for the fire detection control panel Series BC216
In a fire detection system a series of peripheral devices such as fire detectors, sirens, transmitting de-
vices, displaying devices, etc. are used which are activated and/or monitored by the fire detection con-
trol panel.
2.4.1 Detectors
Fire detectors of a fire detection system are combined locally to fire protective efficient detector zones
and connected to the fire detection control panel BC216-1 or to the BCnet sectional control panels of a
fire detection control panel BCnet216. The location of fire is identified by the zone number(s) dis-
