4.6 - Infrared detector with volumetric lens
(model HSDIM11)
4.6.1 - SPECIAL WARNINGS
To avoid intentional damage, install the product in a position that is difficult
to reach
• Do not install the product near possible hot or cold air turbulences or
where there are animals (hot blooded).
• If pets enter the environment controlled by the sensor the sensor must be adequate-
ly positioned and aimed so that the sensitivity area is 50-70 cm above the ground as
shown in fig. 23; if necessary, reduce sensitivity of the sensor.
4.6.2 - PRODUCT DESCRIPTION AND INTENDED USE
HSDIM11 is an infrared detector with volumetric lens for indoor use; it detects the
movement of an intruder in the protected area and transmits it via radio to the control
unit to which it is associated. Any other use is to be considered improper and prohibit-
ed! Nice declines all liability for damage resulting from improper use of the product and
any use other than that specified in this manual.
4.6.3 - OPERATION
HSDIM11 is an intruder detector that signals the movement of people in the protected area.
To increase protection it is fitted with a second input for NC type contact which can be
used to connect another sensor, also pulse type (detector for rolling shutters); the alarm
can be single or differentiated for the two different detections. It contains anti-tampering
and anti-break-in detectors.
Communication is completely via radio with dual band technology; battery operated –
standard 9 V. Equipped with LED indicator visible from the outside.
Types of alarm signal:
– Intruder alarm: alarm signal caused by the detection of movement in the protected
area. In order not to waste the batteries the detector does not send out any other
signal after the first alarm signal if there is no further movement for at least 2 minutes
(except when the battery compartment is open).
– Second alarm: the HSDIM11 can be programmed to transmit 2 different alarms
(transmission of 2 different codes): one for movement detection and one for the NC
contact.
– Supervision: transmission of a signal every 40 minutes to indicate that the system is
running.
– Anti-opening protection: the opening of the battery compartment and/or separa-
tion of the device from the surface on which it is fixed triggers the "tampering" alarm.
To avoid this set the control unit to "TEST" mode before opening the sensor.
– External LED:
• when the LED comes on for 1 second it indicates that there has been an alarm
signal;
• after the alarm signal, if the LED flashes quickly 4 times it means that the battery is
almost discharged.

Replace the battery only when the control unit indicates that the detector has a dis-
charged battery. To replace the battery see the instruction manual of the HSDIM11.
4.6.4 - INSTALLATION
For installation operations see the instruction manual of the HSDIM11.
4.6.5 - PROGRAMMING OF DIP SWITCHES
Caution! – To program the "dip-switches" remove the battery from the device;
remove the battery also to make any changes and then reprogram.
Dip-switch functions (fig. 24):
1 OFF = sensitivity: for range of about 5 m.
1 ON
= sensitivity: for range of about 10 m.
2 OFF = non-differentiated alarm signal: transmission of single code for both alarms.
2 ON
= differentiated alarm signal: transmission of 2 different codes, one for the
detector alarm and one for the alarm of the NC input.
3 OFF = immediate alarm signal of opening of NC input.
3 ON
= alarm signal after 6 pulses on NC input.
4 OFF = alarm signal when movement of the intruder is first detected.
4 ON
= alarm signal when movement of the intruder has been detected twice.
5* OFF = Anti-removal/tamper protection enabled.
5* ON = Anti-removal/tamper protection disabled (to be used when fixed on irregular
or unstable surfaces)
6*
= Not used.

4.6.6 - CONNECTION OF EXTERNAL DEVICES
To connect external sensors using wires to the NC contacts see fig. 25. With dip-
switch 3 set to "ON" the input is suitable to control rolling shutter detectors or inertia
sensors where the alarm is signalled after 6 pulses in 30 seconds.
The NC input is automatically activated by closing the contact for about 10 seconds
after inserting the battery.
To memorise the detector in the control unit see chapter 6.2.4.
If the NC input on the terminal board is used and a differentiated alarm is required, the
following memorisation steps must be carried out:
• at first leave the dip switch N° 2 = OFF (non-differentiated alarm)
• set the control unit for the memorisation of the first code (infrared detector); then
insert the battery to carry out memorisation
• set the control unit for the memorisation of the second code (NC input); then move
the dip switch N° 2 = ON when requested to "insert battery in detector".
