"Blackboard light":
■
Additional illumination can be switched on and off separately. E.g. illumination for a
blackboard in school classrooms. The additional illumination also switches off
automatically together with the ceiling lights.
–
The additional lighting is operated with a separate push-button connected via the
6494-500 Extension unit connection.
–
The additional switching output must be configured as a panel light through the app.
"Manual":
■
The additional switch contact (actuator 2) is switched only manually via the app. There
is no dependence to actuator 1 (e.g. DALI output).
"HVAC":
■
The "HVAC" operation mode (heating, air conditioning and ventilation) enables a purely
presence-dependent switching of the additional switch contact (actuator 2). The ambient
brightness is not taken into consideration here.
This function, for example, is used to control a fan motor in WC facilities.
Extension unit operation
–
An additional operation for on/off switching via a push-button:
–
For Monoblock devices on extension unit input 1C of the presence detector.
–
For ABB flexTronics
mounted insert used.
–
A manual change of the current switching state can be implemented. The return to
automatic mode and/or previously selected operation mode takes place after the room is
left plus the set switch-off delay.
–
The lighting is also switched on in semi-automatic mode through the operation of this
extension.
Continuous ON
–
The lighting is switched on. For devices with infrared remote control, the duration amounts
to 8 hours. For devices with Bluetooth function, the duration is freely selectable through the
smartphone app "ABB Watchdog Remote control".
–
To activate this function, press the corresponding button on the IR service remote control
6843.
–
A renewed press of the button on the remote control deactivates the continuous light ON
function.
–
Only Monoblock devices:
–
For the activation of this function, a push-button is connected to channel 1 of the 6494-
500 Extension unit connection. In the case of the DALI main unit, the "Continuous Light"
function must be activated via the extension push-button.
–
The return to automatic mode and/or previously selected operation mode is
implemented through one of the following possibilities:
Push-button/extension operation (directly connected to the extension input 1C of the
■
presence detector).
Simultaneous actuation of the push-buttons for "Continuous ON" and "Continuous
■
OFF".
Via app.
■
Automatic after the expiration of the "Continuous ON" time.
■
–
This function cannot be combined with the panel light.
