photo electric (optical) and ionization.
2.2.2 Sensor
Sensor = Analog detector
2.2.3 Analog detector
Contains an A/D-converter. The Control Unit pick up the digital
values ("sensor values") for each detector individually. All
evaluations and "decisions" are then made in the C.U. Analog
detectors are addressable – an address setting tool is used for detector
types 3xxx and a DIL-switch in the ASB (see below)for detectors
2xxx. An analog detector has to be plugged in an ASB.
2.2.4 (Analog) Sensor Base (ASB)
A sensor is plugged in an ASB, which is connected to a COM loop
(see below). Sensor Base types 2xxx have a DIL-switch for COM
loop address setting.
2.2.5 Conventional detector
Detector with two states, normal or fire alarm. The detector contains a
closing contact and a series alarm resistor. Some types are plugged in
an ADB (see below) or a CDB (see below). Some types are also
available as addressable, to be connected to a COM loop (see below).
(Normally plugged in a CDB (see below), connected to a conventional
zone line with end-of-line resistor.)
2.2.6 Conventional Detector Base (CDB)
A conventional detector is plugged in a CDB, connected to an external
line, an addressable zone interface, conventional zone line, etc.
2.2.7 Addressable Detector Base (ADB)

Unit intended for fire alarm presentation, etc. for the fire brigade
personnel. Can be a part of the control unit (front adhesive) or a
separate unit; an external FBP.
In the ext. FBP. a printer can be included or not included.

Brief explanations to the words/expressions to be found in connection
with a "network". See also separate TLON Technical description.
TLON®= TeleLarm Local Operating Network = a LonWorks®- based
network1for communication between several control units (nodes).
The protocol is LonTalk and the transmission works with doubly-
terminated bus topology (Echelon FTT-10). To connect a control unit
to the network, a TLON connection board is plugged in the control
unit. (Some old types of control units, not prepared for network
connection, have to be connected via a serial interface and a
Gateway).
A network can be one channel (FTT-10) or several channels,
connected via routers or repeaters.
Repeaters are used to increase the maximum cable length, C.U. to
C.U. in a network.
1LonWorks®= A "summing-up-name" for the market of Echelon
Corporation Inc. technology.

activated when the control unit door is opened. In some
configurations does a key switch replace this door switch.
The LED "Key switch" is indicating "door open" / key switch in
position "access".
2.18 SSD / Site Specific Data
This data is unique for each installation. All alarm points,
presentation numbers, user definable text messages, programmable
outputs, etc. are programmed (configured) in the PC program Win512
and has to be downloaded in EBL512.
2.19 SW / Software / System program
The SW makes the control unit (the microprocessor) work. It is
factory downloaded but a new version can be downloaded in EBL512
on site.

3 Overview
3.1 The EBL512 system
EBL512 is a microprocessor controlled intelligent fire alarm system,
intended for analog addressable smoke detectors, as well as
conventional detectors and manual call points. Programmable control
outputs and output units are available. Up to 512 addresses can be
connected to each control unit (c.i.e.).
Regarding alarm points, outputs, display units, etc. see chapter
"Definitions / Explanations", page 6.
EBL512 is available in several types, versions and configurations. It
can be connected to a TLON network, a "system", with up to 30
independent control units. Each control unit has total access to all
information.
EBL512 is designed according to the European standards EN 54, part
2 and 4.
3.1.1 Expansion boards
In the control unit (c.i.e.) it is possible to mount up to six expansion
boards. The following types are available:
1580 8 zones expansion board
1581 8 relays expansion board
1582 External FBP interface board2
1583 German FBP interface board3
1584 Autronica interface board (four BS4 loops)4
Regarding the expansion boards, see the EBL512 Planning
Instructions.
3.1.2 Printer
In control unit 1548 it is possible to mount a 1558 Printer.
3.2 SW versions
Due to continual development and improvement, different SW
versions could be found. When installing a new control unit in a
system with "older" control units, you may have to update the SW in
the old control units.
2Max. two 1582 boards per C.U.
3Max. one 1583 board per C.U. 1583 board is not possible to use in
Swedish convention.
4Max. four 1584 boards per C.U.

3.3 Documents
The following documents are available:
•Planning instructions (incl. drawings)
•Operating instructions
Normally information that is found in one document is not to be found
in another document, i.e. the documents complements each other.
3.4 Applications
The EBL512 system is intended for small, medium and large
installations. The intelligent control units offer the system designer
and end user a technically sophisticated range of facilities and
functions. Programming (PC SW Win512) and commissioning of the
control unit / system is very easy. Start with one control unit and then,
when required, add more units. The TLON network makes it possible
to install the control units in one building or in many buildings.
3.5 PC SW
Win512 is used for programming and commissioning of one or more
control units:
•download / backup of site specific data
•download of SW / settings / configurations / C.U. & system data
•create and download the user definable text messages shown in
the alphanumeric display in the C.U. / ext. FBP and in the Display
units.
TLON Manager is used for programming of network data / addresses
/ etc.
NEWTEXT (DOS based "older" program) could be used to create /
download the user definable text messages shown in the Display units
connected to the COM loops.

4 Control Unit
Figure 1. EBL512 Control Unit (1548 / 1549). The look may
vary according to configuration, country, etc.
The control unit (c.i.e.) is housed in a grey metal cabinet. The door
has a Plexiglas ahead of the FBP part, see Figure 1. When the door is
open, you fully see the front adhesive (the Fire Brigade Panel, FBP,
and Control Panel, CP), see Figure 2.
Figure 2. Front adhesive; FBP (upper black part) and CP (lower
grey part) in EBL512. The look may vary according to
configuration. (English config. in figure).
The fire brigade personnel use the FBP to see which alarm point(s)
having generated fire alarm. In the display (LCD, 2x40 alphanumeric
characters), is on the first row displayed the zone number and the

address within the zone. On the second row is shown a user definable
text message, if programmed.
Required fire brigade personnel manoeuvres can be performed from
the FBP.
The CP is used to "communicate" with the system, e.g. for
commissioning, monthly tests or maintenance. The CP has several
system status LEDs. A keypad is used to get access to the system (a
menu tree with main and sub menus) and for different manoeuvres.
Access codes for different access levels are required.
