The system includes an electronic relay installed in the electrical panel of the indoor machine and 2
water detectors to be connected in series.
The electrical connections for the probe and the alarm contact are present in the indoor machine's
terminal board.
The sensors are supplied to be connected and installed at customer care.
Is possible to install one or both of the following sensors. Sensors are supplied in mounting kit.
Installation within the room at customer care.
A511 - SMOKE DETECTOR
The device in supplied in mounting kit.
The optical smoke detector senses the presence of combustion by-products (visible smoke) and
activates an alarm.
The operating principle is based on the light scattering technique (Tyndall effect).
The device is in conformity to EN 54-7 standard.

Supplied with unit to be connected and installed at customer care close to the unit.
A512 - FIRE DETECTOR
The device in supplied in mounting kit.
The fire detector has been designed to identify temperatures at which fires may start. When the
temperature exceeds the set threshold or when there is a rapid variation in temperature, the relay is
activated to signal an alarm.
The device is in conformity to EN 54-5 standard.
