Peripheral devices
Alarm points. Analog alarm points (detectors, etc.) are connected
directly to a COM loop. Conventional alarm points (detectors, etc.)
are connected to an 8 zones expansion board (4580) zone line input or
a COM loop unit (e.g. 3361) zone line input. Programmable inputs
can also be used for flow switches etc.
Short circuit isolators can be used on the COM loops.
Sounders, door release magnets, etc. are connected to COM loop unit
(e.g. 3361 / 3364) outputs and/or control unit outputs (S0-S3, R0-R1)
and/or 8 relays expansion board (4581) outputs.
sounders (3377 / 3379) are connected directly to a COM loop.
Input devices as key cabinet, timers, external faults, etc. are connected
to a programmable input, i.e. to COM loop unit (e.g. 3361) inputs
and/or to the control unit inputs (I0-I3).
Routing equipment is normally connected to the control unit outputs
"Fire alarm" (for Fire brigade tx) and "Fault condition" (for Fault tx).
(Also, any programmable output can be used).
External Fire Brigade Panels and External Displays Units are
connected directly to the RS485 channel.
As an alternative the RS485 channel can be used for:
German Fire Brigade Control Panel (FBF) and German Fire Brigade
20
Indicator Panel (FAT).
More information, see the Product Leaflet for the device respectively.
COM loop units
Each COM loop (0-3) can handle up to 255 addressable COM loop
units, i.e. in total up to 1020 COM loop units, of which max. 512 can
be alarm points. Depending on the type of units and the number of
units the total current consumption will vary and this will affect the
cable length.
See chapters "COM loop cable length", page 145,
"Current consumption", page 148 and dwg 512 G3 - 41.
NOTE! The control unit can be configured for up to 128, 256 or 512
alarm points. Normally this is factory set but can be changed on site
21
(via WinG3)
. In menu H4/U7 is the current configuration shown.
The units should be distributed as even as possible on each COM loop
and between the COM loops (0, 1, 2 & 3). Up to 1020 units can be
used but max. 512 of these can be alarm points, according to
EN54-2.

If German panels are connected to the RS485 channel, no other units
can be connected to the RS485 channel.
