CUSTOMER FAULT ANALYSIS 

 

8.1  Fault Finding 

 
 

 

FAULT 

 

CAUSED BY 

 

REMEDY 

 
Red LED does not glow on 
power up. 

 
If the indicator is off then there 
is a fault on the power 
connection to the unit. 
 

 
Check power feed to the unit. 

 
After the initial tune period the 
CH1 Green Channel LED 
remains flashing at 2Hz. 
 

 
Unit cannot tune to the loop 
due to faulty loop or feeder 
connection. 
 
 
Loop may be too small or too 
large. 
 
 
Faulty detector unit. 
 

 
Check on-board diagnostics to 
confirm fault. Check loop 
installation and connections. 
 
 
Check on-board diagnostics to 
confirm fault. Recut as per 
installation instructions. 
 
Replace unit. 
 

 
After tuning, the loop output 
LED flashes intermittently and 
the relay chatters. 
 
 

 
The loop is getting spurious 
detects due to: 
 
a) Crosstalk with adjacent 
    detector. 
 
b) Faulty loop or feeder  
    connection. 
 

 
 
 
 
a) Change frequency    
    setting. 
 
b) Check that the feeders are 
     correctly connected and 
     adequately twisted.
