Presence time delay
Presence switch-on delay
Mechanical safety lock
Channel A light
Switching response is controlled by presence and brightness.
The switch contact closes during darkness and when some-
one is present. It opens with a delay when there is brightness
or when no one is present.
Time delay
The time delay enables delayed switching off of lighting after
the room is vacated. The time delay is adjustable in a range
of 10 s to 60 min. If someone goes into an unoccupied room
only briefly and leaves it within 30 seconds, then the light
will be switched off prematurely after 2 minutes (short-term
presence).
Push button control
The lighting can be manually switched at any time via a push
button or switch. If the light is switched on manually, it will
remain on for at least 30 minutes provided that people are
present. It then switches off when the brightness is adequate.
The light is forced off after the preset time delay if the room
was (previously) vacated. If artificial lighting is switched off
manually, the lighting remains switched off as long as the
room is occupied. The lighting switches again automatically
after the time delay has expired.
Fully or semi-automatic device
Lighting control can be fully automatic for increased comfort,
or semi-automatic for greater energy savings. The lighting
switches on and off automatically as a "fully automatic
device". As a "semi-automatic device", the lighting must
always be switched on manually. The lighting is always swit
-
ched off automatically.
Pulse function
Time delay can be set to pulse for controlling existing stair-
case light timer switches. To do so, the light output produces
a pulse of 0.5 s in duration every 10 s if people are present or
it is dark.
Channel H presence
Channel H presence is used for HVAC control. The switching
response of the floating contact is influenced only by pre
-
sence and not by brightness. If the contact is closed, the time
delay will be restarted at every movement. Push buttons or
switches do not influence the contact.
Switch-on delay
The switch-on delay prevents instantaneous switching on.
The contact closes only on expiry of the switch-on delay,
provided that people are permanently present.
Time delay
The time delay enables delayed switching off of HVAC devices
and systems after the room is vacated. The time delay is
adjustable in a range of 10 s to 120 min.
5. Detection area
The rectangular detection area of thePassa presence detec-
tor covers a large detection area, and permits a complete
coverage of the corridor. It is possible that, in certain areas,
the detection area is larger than stated. Please bear in mind
that, based on the walking direction, the detection area is
divided into different sectors. The recommended installation
height is 2.0 m – 6.0 m. As installation height increases, the
sensitivity of the presence detector decreases.
From installation heights of 3.5 m, the detection areas of
several detectors should overlap in the marginal zones. The
detection range is reduced as the temperature increases.
The detection area is divided into two zones. These can be
easily activated or deactivated by using the remote control.
