The Electronic Control Unit has an alarm signalling relay. Its contact is closed during normal operation and is opened in the
case of an alarm or a power blackout.
Refer to the wiring diagram for the relative connections.
In TAEevo Tech MINI 08-10 models a green light remains on to indicate that there are no alarms in the unit.
If an alarm occurs, the light turns red to indicate its presence.
