Joint alarm
It may be difficult to notice alarms if the unit is located in a place where access is difficult or infrequent, and if the control panel is locat
-
ed in the same place.
An external alarm indicator in the form of an electric bulb or an acoustic signal can be connected to the ventilation unit and announce
when an alarm occurs. This could, for example, be when filters need replacing.
Fire thermostat / external fire automation system
The ventilation unit can be connected up to an external fire thermostat that will stop the ventilation unit in the event of fire. The same
port can be used for connection of an external fire automation system.
The control system registers a broken input signal as fire, and stops. It will only restart once connection to the fire thermostat has been
reestablished or the external fire automation system starts signalling again. This must be done manually through the PC Tool program.
When you connect up an external fire automation system, the ventilation unit will have to restart automatically. You can set it to do so
in the PC Tool program. Please consult the software instructions for further information.
ATTENTION
The setting of which signal to send is made in the PC Tool program.
