General
EBL128 is an Analog addressable fire alarm system but can also be used with conventional detectors. The CIE can communicate with up to 128 input and/or output units on a single loop. The loop is used for connecting detectors, manual call points, and general inputs and outputs for freely programmable customer specific functions. EBL128 fulfils the EN54 standards: EN54 part 2 (control and indicating equipment) and EN54 part 4 (power supply).
EBL128 - a unique concept for early detection without unwanted alarms.
The EBL128 is a member of 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 Analog detector in the system is individually set so that it adapts to the surrounding environment. The sensitivity of each Analog detector is constant in spite of the individual contamination or background particle level. Every long term 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.
A family of state of the art Analog 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 detector loop:
- Analog detectors
- Conventional detectors
- Addressable manual call points
- Addressable short circuit isolators
- Monitored addressable output units
- Addressable output units
- Addressable sounders and sirens
EBL128 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 Analog detector.
- 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.
- Up to 8 display units such as external fire brigade panels or alert annuncation controllers can be connected to each CIE.
- Can be connected to WEB-server for remote access and/or one-way communcation to external system.
Control Unit 4550 is a complete system with one loop for 128 addresses. The CU is equipped with an internal power supply unit. Batteries are placed inside the cabinet. Up to 4 expansion boards can be connected internally.
Expansion boards are:
- 8 zones expansion board 4580. Expansion board for 8 detector zone lines. 2 boards can be connected in in CIE.
- 8 relays expansion board 4581. Expansion board with 8 programmable change-over relay outputs.
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 Win128 PC software which is a complete support packet for the EBL128. All configurations is done in the PC and downloaded into the control unit.
