4383 Light indicator. 4383 is a light indicator used to complement the audible alarm
devices. It is of type A for indoor use. All electronics and the eight red LEDs
(visible 360°) are mounted in a transparent ABS housing. Flash rate is 1 Hz. 4383
is COM loop powered, i.e. the number of indicators is dependent on the type and
number of other units connected to the COM loop. The light indicator is plugged
in an analogue detector base 3312, 3379 or 4313 and an analogue detector is
plugged in the light indicator.
A control expression for activation has to be programmed, similar to a
programmable output or alarm device. It takes one COM loop address. For
more technical data, see the Product Datasheet.
The COM loop address is set with the Address setting tool 3314 / 4414. The unit
has a label for the COM loop address and another label for the detector's COM
loop address.
The Address setting tool is also used for mode setting:
NORMAL mode: 4383 used in system FT128.
6.1.4 Short Circuit Isolators (Addressable)
According to the Australian standard AS1670.1, at least one Short Circuit Isolator must
be used every 40 alarm points on the COM loop. Up to 64 isolators can be connected
to FT128 COM loop.
Each COM loop Short Circuit Isolator is to be programmed (via EBLWin) for the
following:
Technical address
Name (Normally not changed)
Sequence Number (Serial Number in the COM loop’s A-direction) 0-63
For connections, see drawing F733.
4313 Analogue base with isolator. 4313 is an Analogue base with built-in Short Circuit
Isolator. In case of short circuit on the COM loop, the number of disabled units will
be minimised. 4313 is a COM loop powered unit. For more information, see the
Product Datasheet. The COM loop address is set with the Address setting tool
3314 /4414. The unit has an address label on which the programmed COM loop
address is to be written.
The Address setting tool is also used for mode setting:
NORMAL mode: Used for 4313 in system FT128.
Up to 64 Short Circuit Isolators can be used, which give 65 loop segments. Each isolator
has to be given a Sequence Number 00-63. The isolators have to be connected
consecutively (Sequence Number 00-01-02-03-04-05-06-07-08-09-10-11-12-13-14-15 …
up to 63) in the COM loop's A-direction.
Note: FT128 has one built-in isolator in the-A direction (no. "A") and one in the B-direction
(no. "B").
Short circuit / cut-off (break) on the COM loop
See Refer to Chapter 11 “Short Circuit Isolators” page 92 for more information. See also
FT128 Operation Manual, Section "Fault messages".
The units 4433, 4439 and 4477 have a built-in isolator that doesn't occupy any COM loop address and the isolator’s Sequence
Number is set in the dialog box for the 4433, 4439 and 4477 unit respectively.
