Short circuit isolators (addressable)

According to the EN54 standard, at least one short circuit isolator is
required per 32 alarm points on the COM loop. In the Australian and
New Zealand conventions at least one isolator per 40 alarm points.
National regulations have to be followed.
Up to 64 isolators can be used per COM loop.
Each COM loop short circuit isolator is to be programmed (via
EBLWin) regarding:

54
Technical address

Name (Normally not changed)

Sequence Number (Serial Number in the COM loop's A-
54
direction.) 0-63.
Connections, see drawing 128-21. (See especially about the L wire!)
4313 Analog base with isolator.
built-in short circuit isolator. In case of short circuit on the
COM loop, the number of disabled units will be minimised.
4313 is power supplied via the COM loop. For more
information, see the Product Leaflet. 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 EBL128.
2330 mode: Not used in system EBL128.
2312 mode: Not used in system EBL128.
Up to 64 isolators can be used, which gives 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! EBL128 has one built-in isolator in the-
A direction (no. "A") and one in the B-direction (no. "B").

The units 4433, 4439 and 4477 have a built-in isolator that don'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.
