Automatic brightness control of the device
In the standard version, a lighting sensor is included. The device, in response to the intensity of daylight, adjusts
the brightness of the clock display.

Executive relay module
The device is equipped with an embedded executive relay, which enables signalling up to 30 alarms. The duration
of each alarm can be set in a time interval between 1 and 59 seconds. Sample applications:
1)
Activating an acoustic signalling device for industrial applications
4
, signalling, for example, a break or a shift
rotation in an industrial plant;
2)
Activating a school bell;
3)
Giving a time signal to separate systems or devices.

There is a possibility to connect a different signalling device (e.g. visual or visual-acoustic) to the relay connector. In
such case, be careful not to exceed the relay electric parameters.
