HSDIM24 is a volumetric presence detector with dual technology, infrared and microwave
radar. It is designed to cover an area of up to 12m (27 zones over 3 floors) with an opening
angle of 100°; it includes sensitivity and alarm type adjustment (immediate or on second
pulse), protection against opening, removal and blinding attempts. Suitable for indoor use.
Any other use is to be considered improper and is strictly prohibited! Nice
declines all liability for any damage resulting from improper use of the product
and any use other than specified in this manual.
1 - OPERATION
HSDIM24 is a dual technology volumetric presence detector (PIR = passive infra-red
detector + MW = micro wave Doppler detector) designed to detect a person moving
inside the protected zone. The two different technologies reduce the possibility of improper
alarms due to environmental factors. Correctly position and adjust the product for optimal
operation. The use of the adjustable joint mod. HSA4 (optional accessory) allows the prod-
uct to be correctly positioned.
HSDIM24 works with 3 AA type alkaline batteries; it has no external electrical connection
and if intrusion is detected, it transmits the alarm to the control unit via radio.
In the product, the infrared detector is always active and, if an intrusion event is detected
(green LED on), it activates the microwave detector immediately (orange LED on); if this
one also confirms the existence of a moving body, the alarm status is generated (red LED
on).
HSDIM24 has a function to reduce battery consumption in the event it is used to protect
a heavily used area; as a matter of fact, after each alarm it suspends its operation and
restarts after 2 full minutes of no movement in the protected area.
To check the operation of HSDIM24, simply set the control unit to test mode and remove
it from its sliding bracket; for 3 minutes the block function is cancelled after an initial alarm
and HSDIM24 transmits and displays all the detected events through the LEDL1 (fig. 2).
Caution! – When the top cover of HSDIM24 is removed, the system stays in "TEST"
mode.
The detector has protections against removal and opening and against attempts to blind it.
HSDIM24 transmits a signal to the control unit every 28 minutes to indicate that the system
is running; this is necessary for the "supervision function" present on the control unit.
