A detector with only two statuses, i.e. normal or fire alarm. The
detector has a "closing contact" and a series alarm resistor.
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 zone line.
A conventional detector is plugged in a CDB, connected to a
conventional zone line input.
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 (It can also be one
of Brooks addressable modules 1200,1202 & 1203).
Input intended for one or more conventional alarm points. End-of-
line device in the last alarm point on the zone must be fitted.
Addressable unit with programmable control outputs. Connected
to a COM loop (see below).
Defined or programmable function. Relay output or voltage output
(supervised or non-supervised), in the FDCIE or an output unit
connected to a COM loop.
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 zone on the COM loop.
Addressable unit (RS485 line) for fire alarm presentation
(including user definable alarm text), alert annunciation, etc., end
of line resistor must be set via a jumper link on the last unit.
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 = 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.
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
personnel.
A part of the FT1020G3 front display, intended for fire brigade or
service personnel, building officer, etc., to "communicate" with the
Control Unit / system. It comprises the bottom part of the front
display.
One or several control units connected via a TLON network (co-
operating control units).
Brief explanations to the words/expressions to be found in
connection with a "TLON Network". See also separate TLON
Technical description.
TLON® = TeleLarm Local Operating Network = a LonWorks®-
based network for communication between several control
units/nodes. The protocol is called LonTalk and the transmission
works with doubly- terminated bus topology (Echelon FTT-10).
To connect a control unit to a network, a TLON connection board
has to be plugged in each control unit. FT1020G3 also supports
a redundant TLON Network. In this case two TLON connection
boards have to be plugged in each control unit.
A network can be one channel (FTT-10) or several channels,
connected via routers. In TLON Network, subnet = channel.
Routers are used for safety reasons in a single TLON
Network (up to six control units per channel). Routers can also
be used to increase the distance (cable length) between the end
nodes in a channel.
