Wiring

The wiring between the transmitter / detector / push-button and the station should NEVER be installed in a
conduit alongside power, control or supply cables.
Always disconnect the power supply to carry out wiring.
For disconnection, the power supply circuit must be equipped with a switch of at least 2 A, 230 V, located near
the device. The power supply cable will be H05VV-F or NYM 1x16/3. The section to be used will depend on
current local regulations, but should never be less than 1.5 mm .
Cables for wiring the relay contact should have the relevant section for the device to be connected
The 120 / 230 V~ wiring area must be kept clear of any other external element.
Certain international standards indicate that alarm power supply should originate from a different circuit to
that used for the refrigeration and ventilation system. Be sure to comply with current local regulations.
