Switching Behavior in Semi-automatic Mode
The behavior in semi-automatic operation is basically the
same as in fully automatic operation, except for the fact
that the lighting is never switched on automati-cally, i.e.
it must always be switched on manually.
“Room or Corridor” Push Button Function
By means of the DIP switches, the function of the push
button(s) can be set to “Room” or “Corridor”. In the
“Room” position, the lighting can always be switched on
and off manually, whereas in the “Corridor” position, the
detector is used as staircase lighting timer, i.e. the light
cannot be switched off manually.
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.
Switched Output for Presence
The switched output for presence is used for HVAC cont-
rol and room surveillance. The switching behavior of the
potential-free contact is only affected by presence and not
by brightness. The contact closes in case of presence and
opens in case of absence. The contact is not affected by
the push buttons.
HVAC Control with Switch-on Time Delay
The switch on delay (0s - 10min) prevents that the system
is switched on immediately. The contact does not close
before the switch on delay time has elapsed, provided of
course that persons are present all the time. If the con-
tact is closed the switch off delay time (10s - 120min) is
restarted at each detection of movement.
Room Surveillance
If the switch on delay is set to “Surveillance”, the sensi-
tivity of the switched output for presence is reduced. The
contact closes in case of distinct move-ments only and
thus reliably indicates the presence of persons. The switch
off delay time remains active. The switch-on time delay is
inactive.
Interconnection
In single unit operation, the compact office is set up to
detect presence and brightness and controls the lighting
and HVAC/surveillance by means of its two contacts. If
the detection range of one detector is insufficient (e.g.
in case of very large rooms) up to 10 detectors can be
connected in parallel by interconnecting the P-terminals
of the detectors. Depending on the application, a detec-
tor is referred to as master or slave. Master and slave are
identical devices with different wiring.
“Master-Slave” Parallel Connection
The detector controlling the lighting is always referred to
as master. The brightness measurement and the adjust-
ment of all potentiometers is done centrally on the mas-
ter. Any push buttons are connected to the master only,
and the entire load is switched by the master. Any further
detectors are referred to as slaves. Their only task is to
supply the presence information.
