Conventional detector
A detector with only two statuses, i.e. normal or fire alarm. The
detector has a "closing contact" and a series alarm resistor (560
Ohm). Normally plugged in a conventional detector base CDB
(see below), which is connected to a conventional zone line input.
Some types are water proof types and cannot be plugged in the
standard base, it is connected directly to a zone line. An end-of-
line device has to be connected in the last unit on the
Conventional Detector Base (CDB)
A conventional detector is plugged in a CDB, connected to a
conventional zone line input.
Addressable
A unit with a built-in address device. Each unit is individually
identified, handled and indicated in the FDCIE. (The unit can be
an I/O unit with a zone line input, to which one or more
conventional "alarm points" can be connected.)
Conventional zone line input
Input intended for one or more conventional alarm points. End-of-
line device in the last alarm point on the zone must be fitted.
Output unit
Addressable unit with programmable control outputs. Connected
to a COM loop (see below).
Output / Control output
Defined or programmable function. Relay output or voltage output
(supervised or non-supervised), in the FDCIE or an output unit
Short circuit isolator (ISO)
Addressable unit for automatic disconnection of a COM loop
segment (see below) in case of short circuit on the loop. As per
AS1670.1, one isolator is required every 40 alarm points on the
Remote Display Unit (RDU)
Addressable unit (RS485 line) for fire alarm presentation
(including user definable alarm text), alert annunciation, etc. Two
types are normally used: External presentation unit 1728 (EPU)
and alert annunciation unit 1736 (AAU).
Note: In standard FT1020G3 software ≥ V2.4.1, up to 30 display
units (1728 / 1736) can be connected, end of line resistor must be
set via a jumper link on the last unit. For more information, refer to
the technical manual of 1728 and 1736
COM loop
Loop = twisted pair cable, to which all the addressable units can
be connected. Starts in the FDCIE and returns back to the FDCIE.
Control Unit / C.U. / FDCIE
Control Unit = Fire Detection Control and Indicating Equipment
(FDCIE) = Unit to which the alarm points are connected (via e.g.
a
COM loop). Indicates on the front fire alarm, fault conditions, etc.
Fire Brigade Panel (FBP)
The fire brigade panel is an integral part of FT1020G3 intended
for fire alarm, fault and disablement presentation, etc. The FBP
compromises the top part of the front display.
Intended for fire alarm presentation and for the fire brigade
Control panel (CP)
A part of the FT1020G3 front display, intended for the building
occupier / officer, service personnel, etc., to "communicate" with
the Control Unit / system. It comprises the bottom part of the front
System / Installation
One or several control units connected via a TLON network (co-
operating control units).
Network / TLON® / LonWorks® /
Echelon / Node / TLON Conn. board
/ Channel / Backbone net / Router /
Repeater
Brief explanations to the words/expressions to be found in the
relevant documents. Refer to the TLON Technical Manual.
TLON® = TeleLarm Local Operating Network = a LonWorks®-
based network for communication between several control units /
LED
LED (Light Emitting Diode) = Yellow, green or red optical indicator
("lamp").
External Indicator / RIL
A unit with a red LED connected to a base (ASB / CDB) or a
detector with an output for a remote indicator RIL.
Lit when the built-in LED in the detector / base is lit.
