Conguration N4640
Infrared ray detectors require assignment of the appropriate zones and the progressive
number of the sensors in the zone, setting of the detection mode and possibly
assignment of an auxiliary prealarm channel.
Z
This congurator assigns the number of the appropriate zone to the detector.
Congurator 1 assigns zone 1 to the detector, congurator 2 assigns zone 2 and so on to
a maximum of 8 zones.
N°
This congurator assigns the progressive number of the detector inside the appropriate
zone.
Congurator 1 identies the rst detector, congurator 2 identies the second and so on
to a maximum of 9 sensors (IR detectors and contact interface) for each of the 8 zones.
This congurator sets the sensor detection mode.
It can be used, for EXAMPLE, when the device is directed towards a possible source of
disturbance (window or radiator), and its position cannot be changed.

AUX
Auxiliary function activation. The device, in any system
status (enabled or disabled), sends an auxiliary alarm
to the channel specied in the AUX position. If the
assigned zone is divided, the auxiliary command will
be disabl
ed.
AUX
If the AUX congurator has been connected to the
position, the 1 to 9 value of
the congurator in this position activates the auxiliary function assigned to the 1 to 9
number of the auxiliary channel.
If no congurator, or one of the congurators from 1 to 7 is connected to the
position, the device only activates the auxiliary function when the system is disarmed.
High sensitivity = maximum coverage 9 metres
Medium sensitivity = maximum coverage 6 metres
Low sensitivity = maximum coverage 3 metres
