1.1.2.1  Card Missing/Failed 
 
   
Description: 
 
The circuit card is not communicating correctly with the panel controller. 
 
Possible causes: 
 
  Card has not been fitted 
  Card is not seated correctly on connector  
-  Power down panel, clean connectors and reinsert 
  Card has not been addressed correctly 
  Card DIP Switch incorrectly set (Dipswitch 1 always in ON position) 
  Another card has been addressed the same as this card 
  Card has failed 
 
1.1.2.2  Correct Card Abnormal 
 
Description: 
 
The wrong type of card has been addressed at this location. 
 
Possible causes: 
 
  Incorrect card fitted in the panel. 
  Two cards have the same address. 
 
1.1.2.3  Short Circuit Abnormal 
 
Description: 
 
The addressable loop has a short circuit or the + and – wires are crossed over. 
 
Possible causes: 
 
  If there are no isolators fitted or the short is between the panel and the isolator then the loop will stop 
operating. This may also display a channel fail 
  Find the short circuit and fix – disconnect the loop totally, check each pair for a short circuit with a 
Multimeter.  If  fault  evident  continue  these  checks  at  half  way  points  around  loop  until  short  is 
narrowed down 
  If  short  circuit  cannot  be  detected  with  a  Multimeter,  disconnect  one  side  of  the  loop  only  and 
disconnect  devices  at  half  way  points  until  the  short  circuit  fault  clears,  to  narrow  down  the  fault 
location.  
 
NOTE:   Panel will need to be reset between each disconnection as this fault will latch
