Switched Output for «Light»
The switching behavior is controlled by presence and
brightness. The contact closes in case of darkness
and
pres-
ence, and opens in case of brightness
or
absence.
The minimum switch off delay time (10s - 20min) and the
desired brightness switching threshold (10 - 1500Lux) are
adjustable. The switch off delay time automatically adapts
to the occupant’s behavior (self-learning characteristic),
i.e. the unit is able to automatically extend the switch off
delay time to max. 15min or reduce it to the minimum set
time.
Note:
The switch-off delay time does not change with a
setting of 2 minutes or less. Optimum switching beha-
viour will be obtained when the switch-off delay time is
controlled from the detector with settings of more than 2
minutes.
Pulse Function
In order to control existing staircase lighting timers, the
switch off delay time can be set to “Pulse”. In this posi-
tion, the switched output for light generates a short pulse
(duration 0.5s) every 10 seconds in case of presence and
darkness.
