5.2. IMPORTANT SAFETY INFORMATION
Please pay particular attention to the following points if hazardous
voltages (>48V) are to be connected to either of the control outputs:
The circuits that the relay contacts are connected to must be of the
same type, i.e. Both mains or both low voltage. It is not permissible to
mix the types of circuit connected to these relays.
These products are Class II Equipment, meaning that they are
designed with double insulation to protect against electric shock
hazards. They must be installed in strict accordance with these
instructions. It is the installer’s responsibility to ensure that any live or
hazardous conductors are properly connected, not accessible to users,
and that the equipment is left in a safe condition.
It is acceptable to connect mains circuits in the frequency range 45 to 65
Hz to these relays.
For currents up to 3 Amps, the minimum conductor cross sectional area
must be 0.75 mm
2
(19awg) for flexible cords, or 1mm
2
(18awg) for other
cables.
Circuits connected to these relays must be protected against over-
current and short circuit by a suitable method, for example a fuse or
circuit breaker rated at less than or equal to the relay contact rating.
The use of an isolated supply or an RCD is recommended for these
circuits.
Cables must be correctly rated and specified for the intended
environment, and of indoor or outdoor type as appropriate.
Extra precautions must be taken for flush-mounted Titan and Help Point
products (where a GAI-Tronics rear enclosure is not used). In this case
it is the installer's responsibility to ensure that the installation is safe, that
there is no possibility of any contact being made to live terminals, that
cables are properly restrained to prevent them becoming detached, and
that there is no possibility of water, dust or other fluids coming into
contact with the rear of the product.
Always ensure that sufficient clearance is maintained between
hazardous voltages and any accessible conductive parts.
If in doubt always use a GAI-Tronics rear enclosure, installed according
to these instructions.
5.3. Emergency Services warning
If, as configured, the telephone cannot make a direct call to the
emergency services, check with your network administrator whether it is
necessary to warn users, and if so provide a suitable warning notice. A
