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 wiresVdS 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 syn-

chronous 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 technol-

ogy, the warning devices in the unaffected fire compartments remain functional,

even without fireproof wiring.

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 possi-ble to deliver sustained operation in a fire situation.

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 add-

itional wiring, power supply

units and longer installation

times.

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 advantages

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 devicesand 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 sounderhas two functions. It serves as a fully functional

alarm device, which generates a uniform 360 sound pressure, and also as a mount-

ing base for Series 9200 fire detectors. Like the base sounder, the addressable

system sounderin red and white contains an isolator. Both the base sounder and

the system sounder are fully integrated bus devices.
