Astra-621

Basic data: – 2 channels of detection: volumetric optoelectronic (IR), surface sound (AC); – microprocessor-based signal analysis; – two optoelectronic relays; – additional protection with a metal shield against electromagnetic interference; – "alarm memory" mode; – mode testing of the AK-channel; – control of the supply voltage; IR: – discrete adjustment of the detecting ability; – anti-tampering zone; – resistance to external illumination of at least 6500 lx AC: – detection of destruction of ordinary glasses protected by a polymer film, – reinforced, patterned, multilayer building, hardened flat; – discrete sensitivity adjustment Tech. specifications Technical data: – IR channel range 12 m – AK channel range 6 m – IR channel detection area angle in the horizontal plane 90 ° – recommended installation height 2.4 ÷ 2.5 m – supply voltage 8 ÷ 15 V – current consumption, no more than 15 mA – resistance of the relay channel in standby mode, no more than 8 Ohm Operating conditions: – temperature from -20 to + 50 ° С – relative humidity of air without moisture condensation up to 95% at + 35 ° С – degree of protection by the shell IP30 Informative value: "exit to standby mode" ; "norm – IR"; "alarm – IR"; "norm – AK"; "alarm – AK"; "supply voltage below the permissible"; "increased level of interference at high frequency"; "increased level of interference at low frequency".
