Short Circuit Isolators (Addressable) - Panasonic Firetracker FT1020G3 CIE Technical And Programming Manual

4383 Light indicator. The light indicator 4383 is used as a complement to 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.
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: Used for 4383 in system FT1020G3.

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 used per
COM loop.
Each COM loop short circuit isolator 4313 is to be programmed (via EBLWin) for the
following:

COM loop 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 a 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 3314 / 4414 is also used for mode setting:
NORMAL mode: Used for 4313 in system FT1020G3.
Up to 64 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: FT1020G3 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 chapter "Short circuit isolators", page 94. See also FT1020G3 Operation Manual,
chapter "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
