BOSCH DS835B-ITA dual technology sensor 15 mt

Equipment: DS835B-ITA

Feeding detector : 9 to 15 V -; 16 mA @ + 12 V - (maximum 48 mA in alarm or fault).

Exit of alarm : "reed" type relay, normally closed, with dry contacts at 28 V -, 125 mA, 3 Maximum watts with resistive loads. Not to be used with type loads capacitive or inductive.

Duration alarm relay activation: 2-3 seconds.

Exit of tamper : Normally Closed Contact (with detector cover closed) for detection of detector cover opening. Clean contacts at 28 V -, maximum 125 mA.

Range of temperature for detector operation and storage : from -40 ° C to + 49 ° C (performance not IMQ certified).

Container : in white ABS. Dimensions: 71mm (width) x 127mm (height) x 56mm (depth).

Frequency microwave : 9.9 GHz ± 25,000 MHz.

Features microwave : pulse type signal: 20 μ sec. ON and 1 msec. OFF maximum power radiated: 15 mWatt average radiated power: 0.3 mWatt

Flow microwave : adjustable with a special potentiometer.

Orientation PIR detection field : adjustable from + 2 ° to -10 ° vertically by loosening the appropriate adjustment screw

and moving up or down the card so that the vertical angle of the PIR detection field is optimal for the mounting height and for the maximum flow required by the application.
