These make contacts are connected tothe trigger input screw terminals (11). The cabling of the first six trigger input contacts (1 through 6) can havesupervision by means of a window comparator. Normal operation of these inputs requires two series connectedresistors of 10 kOhm and 3.3 kOhm, permanently connected to the far end of the cable connected to each triggerinput. Triggering occurs by short-circuiting the 10 kOhm resistor as shown in figure 3.4.Open or short-circuited cables to such an input result in a fault situation that is detected by the window comparator.The fault indicator LED at the front will light up and the internal fault relay will be unpowered which gives acontact change on the screw terminals (10) at the rear.Via the dipswitches 1 through 6 at the rear of the unit supervision of each individual trigger input (1 - 6) can beenabled ('ON') or disabled ('OFF'). When disabled these inputs act the same as inputs 7 through 12.Via dipswitch # 7 it is possible to enable mains failure checking. When enabled ('ON') the fault indicator LED at thefront will light up and the internal fault relay will go to the unpowered state upon mains failure, although the unitmay continue to work on the 24 Vdc battery.When disabled ('OFF') switching between mains and battery operation is automatic and will not be noticed.Via dipswitch # 8 it is possible to switch ON a 20 kHz pilot tone to the output signal for supervision of the cable byconnecting equipment. The level of the pilot tone is adjustable (from 'OFF' to -14dB with respect to maximum audiolevel) via the pilot tone volume control (1). The default volume level is -20 dB.Bosch Security Systems | 2003-09 | 9922 141 50502en
