6. General instructions
The Supercom 646 Radio Central must only be installed by authorized persons.
The technical specifications of the Supercom 646 Radio Central must be respected.
The lower part of the radio central case is made to be laid flat or fixed to a wall. The attach-
ment to a wall can be done with four screws or a DIN track.
The Supercom 646 Radio Central can be installed horizontally or vertically in an area free of
metallic obstacles.
Radio data transmission quality depends on the wave propagation of the radio central installa-
tion site, the radio connections of the different radio devices as well as atmospheric and geo-
graphic conditions (in particular in enclosed areas or so-called dead zones)
Radio communication cannot be guaranteed at any time and anywhere. The user must check
the radio propagation conditions at the planned installation spot of the radio central Supercom
646.
Keep heat emissions or electrical fields far from the radio central Supercom 646
The radio central Supercom 646 must not be exposed to humidity.
The connection of the power cable to the terminal must be as short as possible.
Avoid electrostatic discharges during installation or manipulation. Before touching the radio
central or a communication interface, one is advised to touch a ground such as a hot water
pipe to discharge oneself of any static electricity.
With the option of the power network module, be careful with high tension power sources.
Avoid touching accessible electronic circuits or contacts.
The RS232 interface cable must not be longer than 5 meters.
6.1.1 Power network stopped or power battery discharged
In case of an electrical breakdown or a dead battery, the clock of the central is always active while
all radio communications are deactivated. It is no longer possible to collect radio device data con-
tained in the radio central list but it is always possible to question the radio central Supercom 646
and read the data of the devices contained in the radio central optically or by the other wireless
methods available.
6.1.2 Care of the batteries
The batteries must not be opened, be in contact with water or short circuited. Empty batteries must
be eliminated in appropriate collection points. Battery life depends strongly on temperature. There-
fore, the Supercom 646 radio central must be installed far from sources of heat or cold. The 2 3V
format A batteries used with the battery powered module soldered to the motherboard must be
identical and correspond to the batteries delivered by the manufacturer. If another battery than the
one recommended by Sontex is used, there could be a danger of explosion.
6.1.3 Changing batteries
If changing batteries, it is imperative only to use the same type of battery.
Always double check with Sontex.
