General
EBL512 is an analogue addressable fire alarm system but can
also be used with conventional or addressable detectors and
addressable inputs or outputs. EBL512 fulfils the EN54 standards:
EN54 part 2 (Control and Indicating Equipment) and EN54 part
4 (Power supply). Every CIE can communicate with up to 512
input and/or output units.
Each control unit has four loops for the connection of detectors,
manual call points, displays and general inputs and outputs
for freely programmable custom specific functions. Each unit
on the loop uses one address.
Every EBL512 unit can work standalone, or can be connected
in an Echelon network, with up to 30 units. Every control
unit has access to all the information from the other units
in the same network. The total number of detectors and/or
input units in a full system is more than 15.000.
EBL512
- a unique concept for early detection without unwanted alarms.
The EBL512 is a new generation of fire alarm systems. With
unique functionality in co-operation with adaptation to the
surrounding environment, self-diagnosis and inter activity
can the system be installed in almost any premises.
* Each analogue detector in the system is individually set
so that it adapts to the surrounding environment. The sensitivity
of each analogue detector is constant in spite of the individual
contamination or background particle level. Every longterm
change is distinguished from short time variations of a smouldering
fire.
* The self-diagnosis function detects every deviation from
the accurate normal condition in the electronic circuits and
in the detection chamber.
* The inter activity function is using information from one,
two or a larger number of detectors in the system to provide
a more secure detection of a real fire.
* A family of state of the art analogue detectors gives the
system accurate and noise free information about smoke and
heat levels in the installation.
System
overview
A
large variety of units can be connected to the four detector
loops:
* Analogue detectors
* Addressable detectors
* Conventional detectors
* Addressable manual call points
* Addressable short circuit isolators
* Monitored addressable output units
* Addressable output units
* Display units
* Addressable sounders and sirens
EBL512
fire alarm system has a set of functions that meets the most
stringent requirements relating to fire detection, presentation
and measure.
* Service signal is automatically emitted when the detector
is contaminated.
* Large number of fire detection algorithms is supported by
the system and can be set to each analogue detector.
* Remote control of the system via global networks.
* Alert annunciation. The output for the alarm transmitter
can be delayed for immediate on site investigation of an alarm.
* Disablements. Zones, programmable outputs and outputs for
the alarm transmitter can be individually disabled.
* Internal or external time channels. Zones may be disabled
using an external timer.
* User programmable outputs. The outputs are programmable
in a very flexible way enabling control of external devices,
such as alarm devices, extinguishing systems etc.
* Compatible with the older EBL1000 and EBL 2000 systems.
* Up to 16 External Fire brigade panels can be connected to
each CIE.
* One-way communcation to external system via data converter.
Network
of EBL512 control panels
The EBL512 control panels can be connected to an Echelon-network
(TLON). Up to 30 nodes can be installed into one network.
One of the nodes can be an external PC. A software driver
that can be installed under Windows NT is provided and gives
the PC full control of and access to all data in the EBL512
control units connected to the network.
Planning,
commissioning and installation tool
Modern fire alarm systems are very complex and versatile.
In order to get the optimal performance and cost effective
planning, installation, commissioning and maintenance of the
system does PEW provide the distributors with a powerful tool.
This tools is the Win512 PC software which is a complete support
packet for the EBL512. All configurations is done in the PC
and downloaded into the control units. |
