esserbus -PLus maximum security, minimum costs www.novar.de
The innovation The latest in ringbus technology: The esserbus -PLus supplies data, signals and power, too, for the direct operation of alarm devices on only 2 wires VdS certified. l For the first time in Germany, thanks to the esserbus -PLus, the certified and approved operation of addressable, loop-powered alarm devices on the ringbus together with fire detectors and other devices is possible. The esserbus -PLus enables alarm devices to be powered directly, tolerant of short circuits and wire breaks, from the 2-wire analog loop. In other words, all participants, including alarm devices, are connected directly to the bus. In an alarm situation, the ring loop increases the voltage to 42 volts and thus provides them with the necessary power. An alarm can therefore be signalled using completely new (wiring) paths: reliably, economically and in conformity with the relevant standards. An additional and unique quality characteristic of the esserbus -PLus is the synchronous alarm signalling function. All sweep and intermittent tones are therefore no longer distorted unrecognisably by the irregular emission of several tones in the fire compartment. For a building sector affected by fire esserbus -PLus means the alarm signal is not compromised until the device itself is destroyed by fire. Thanks to the loop technology, the warning devices in the unaffected fire compartments remain functional, even without fireproof wiring.
The status quo Ringbus technology has been used in modern alarm systems for a long time. However, separate power sources must be provided for high-current devices, such as alarm sounders. This means unnecessary costs are incurred for additional wiring, power supply units and longer installation times. l At present all internal alarm devices must be activated in conformity with various installation standards through monitored circuits. In addition, wiring that bridges more than one fire section, must satisfy the requirements for fire resilience. With conventional resources, this can only be achieved by the costly installation of a separate power unit for each fire compartment. The only exception: the wiring system is realised with powered loop technology and the alarm devices are short circuit and open circuit-tolerant. In this way it is possible to deliver sustained operation in a fire situation.
The advantages The esserbus -PLus enables versatile new system components to be used. A base sounder with an integrated fire detector base and a system sounder are available as alarm devices in conformity with EN 54-3. Both have 4 programmable and approved sounds. The esserbus -PLus offers numerous advantages in terms of security and cost-effectiveness. l Maximum planning reliability l Permanent monitoring of the alarm device l No detailed consideration of fire sections for alarm devices and their wiring paths is needed l Measures to ensure continued functionality of wiring systems with alarm devices can be dispensed with in most cases l Maximum security in cases of alarm l Savings due to lower material costs and shorter installation time l No separate power supply units for fire compartments l Synchronous alarm signalling
System components The addressable base sounder has two functions. It serves as a fully functional alarm device, which generates a uniform 360 sound pressure, and also as a mounting base for Series 9200 fire detectors. Like the base sounder, the addressable system sounder in red and white contains an isolator. Both the base sounder and the system sounder are fully integrated bus devices. Technical data common features: 4 different tones, which can be programmed using the customer data editor Warning tone to DIN 33404 Part 3 Technical data base sounder: Conforms to DIN EN 54-3, VdSapproval G 202046 Sound pressure 93 db (A)/1 m Current: < 6 ma at ring voltage, 22 ma at battery voltage Flush-mount kit available for false ceilings Up to 48 signal bases can be accommodated on one ring loop Technical data system sounder: Conforms to DIN EN 54-3, VdSapproval 202049 Sound pressure 97 db (A)/1 m Current: < 10 ma at ring voltage, 55 ma at battery voltage The sound level in the warning device is adjustable Up to 16 warning devices can be accommodated on one ring loop
