Installation instructions / ACS-2 plus 57
Description of the CPU board shown on the opposite page
Number Explanation
ST1 Extention plug for external modem certified byNovar GmbH
ST2 w.o. function
ST4 Power supply unit connector PIN 1+ 2 = OPEN
PIN 3 >1V-> battery fault
PIN 4 = 10-15V
PIN 5 = 0V
PIN 6 >1V-> power failure
ST5 Watchdog and danger signal output PIN 1 = 0V,
12V semiconductor outputs, 50mA, short-circuit proof PIN 2 = Watchdog output,
PIN 3 =output 6
ST6 Door strike monitoring jumper 1-3; 2-4 = no door strike monitoring
Jumper 3-5, or 4-6 = with door strike monitoring (only
admissible with connected door strike item no. 019 042 /
019 042.01. Deactivate if other devices, such as a flash
lamp, are connected to these outputs/relays).
ST7 Cover contact connection (open = tamper)
ST8 Jumper used to connect the watchdog to the alarm relay.
ST10 Alarm lines 7 and 8 / inputs 11 and 12 PIN 1 = Alarm line 7/ input 11
(terminate with 12.1 kOhm) PIN 2 = 0V
PIN 3 = alarm line 8/ input 12
ST13 Connector for LED board in the housing cover
ST14 Power supply connector for the controller voltage 45 and 46 (with 026547 12V DC, not
stabilized)
ST16 Basic definition of tamper / alarm relay (above board layout version no. 467.00-75-01/02)
Jumper 1-3 = Relay 3 (alarm) activated during system failure
Jumper 2-4 = Relay 4 (tamper) activated during system failure
Jumper 3-5 = Relay 3 (alarm) deactivated during system failure
Jumper 4-6 = Relay 4 (tamper) deactivated during system failure
BU2 Expansion connector for e.g., RAM cards
BU3 Service connector
BU4 and BU5 Slot for the host interface card
LD100 The LED lights up if a watchdog reset occurred previously
LD1 Software LED (see chapters 8.5.1 and 10.1)
LD3 If this LED lights up, then the ACS-2 plus runs with flash 1
LD4 If this LED lights up, then the ACS-2 plus runs with flash 2
Si1 1.0AT, for the terminals 13 and 22
Si2 belongs with ST2, therefore likewise w.o. function (1.0AF)
DB1 and DB2 Grounding/shielding (see chapter 5.1)
