Nice HSDIM24 Instrucciones Y Advertencias Para La Instalación Y El Uso página 4

The detector also has a special "Double Alarm" function to send two consecutive alarms
with two separate radio codes. This particular function acquires the sensor in the AND
mode exploiting the two radio codes transmitted. This allows an alarm to be signalled
only in the event of two consecutive detections, thus reducing the possibility of improper
alarms.
The product includes a protection against attempts to blind it: when an obstacle is placed
in front of the device's lens (10-20cm) a tampering alarm is triggered.
Caution - The use of the Anti-blinding function excludes compliance with standard
EN50131.
Caution - To clean the product, and the lens in particular, place the control unit in Test
mode.
2 - INSTALLATION
Warnings
• Determine the fastening position and height for HSDIM24 depending on the protection
area to be obtained: see fig. 3 and fig. 4.
• Carefully check the shape of the area to protect; if in doubt, prior to the final installation,
it is advisable to fasten the product temporarily and run tests, and then make any neces-
sary adjustments.
• The use of the wall mounting bracket for HSDIM24 makes it easy to replace the batter-
ies by attaching and releasing the sensor from the bracket. To release the sensor, use the
special attachment lever (fig. 5).
01. Select the bracket fastening position, ensuring that it is compatible with the overall
dimensions of the detector: it must be possible to reach the release lever (fig. 5), and
enough space must be available to release and attach the detector.
02. A - Wall mounting: drill two holes for the insertion of the wall plugs and one hole for
the magnet, which is required for the anti-removal protection. Then, fasten the bracket
with the plugs (fig. 6-A) (fig. 11);
B - Fastening with joint mod. HSA4: fix the joint to the wall (see specific instruction
manual) and then fix the Detector to the joint as indicated in (Fig. 6-B). Caution! – By
using the joint HSA4 the anti-removal tamper function is lost. The use of the HSA4 joint
excludes compliance with standard EN50131.
03. Arrange the control unit for the HSDIM24 learning phase (see the instruction manual of
the control unit).
04. Open the battery compartment as shown in fig. 7 and remove the insulation tab that
keeps the batteries disconnected: HSDIM24 emits two series of 3 beeps and its self-
learning program starts; this is confirmed by 1 beep emitted by the control unit (3
beeps indicate that the device is already programmed).
05. Open the detector as in fig. 8 and follow the programming of the dip switches and
jumper JP1 and the adjustment of trimmers PT1 and PT2 (fig. 2), referring to chap.
3 - Programming; then perform the operation "Test", see paragraph 3.1.
06. Close the container and attach HSDIM24 to the mounting bracket (fig. 5).
