Max. distance to the RS485 1 km. (insert a 120 ohm 1/4W resistor in the RS485)
Speed 19.200 bauds
Cable characteristics 2 twisted cables with shielding
Cable section AWG22 (0.35 mm²)
Capacity per metre >90 pF/m (for example, BELDEN 8761-8762 cable)
Accessories
Remote terminal
This accessory allows remote controlling and monitoring
of the unit (up to 040 m.). Functions are the same as the
standard keyboard of the control panel. The remote terminal
is compatible with said keyboard of the control panel, and the
unit can be accessed from both devices. For application, it
must be interconnected to the system by means of the
RS485
serial line connection accessory .
Wall mounting
For wall mounting it is necessary to fasten the rear support
(A) to a standard three-switch modular box.
- Fasten the rear of the casing to the box with the two round-
headed screws.
- Connect the telephone cable.
- Rest the control unit on the rear casing and fasten with
the two flat-headed screws (B).
- Fasten the front panel by pressing lightly.
Electrical connections
Connect the RS485 serial device (separate accessory) to
the RJ2
power supply outlet (included with the remote ter-
minal) and to the monitoring connection of the electric panel
keyboard, using screened cable. Power terminals G-G0 by
means of a transformer and a 250 mAT fuse, following the
enclosed diagram. Connect the RJ2
power supply and
the remote terminal with the included telephone cable (80
cm.). This cable can be replaced by a longer one of up to a
maximum of 40 m.
Attention:
- Use only safety transformers (3 VA, class 2).
- For safety purposes, a 250 mA slow fuse should be inserted
in series with terminal G.
- Do not ground the transformer secondary.
