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.
