Installation instructions / ACS-2 plus
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
ST5
Watchdog and danger signal output
12V semiconductor outputs, 50mA, short-circuit proof PIN 2 = Watchdog output,
ST6
Door strike monitoring jumper
ST7
Cover contact connection
ST8
Jumper used to connect the watchdog to the alarm relay.
ST10
Alarm lines 7 and 8 / inputs 11 and 12
(terminate with 12.1 kOhm)
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)
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)
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).
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
PIN 1+ 2 = OPEN
PIN 3 >1V-> battery fault
PIN 4 = 10-15V
PIN 5 = 0V
PIN 6 >1V-> power failure
PIN 1 = 0V,
PIN 3 =output 6
(open = tamper)
PIN 1 = Alarm line 7/ input 11
PIN 2 = 0V
PIN 3 = alarm line 8/ input 12
