be easily recognised by the flashing ALERT

needs to be entered.  
Depending on how the system has been 
set up by your engineer, it may be 
possible to arm the system with a fault, to 
do this press the I key.

Modem fault 100, Digi Fail Comm, CHC Test Fail, Line Fault 100, ATE Line Fault, ATE Fail Comm, 
Device Fail ###, 485/Comms Lost, SAB Tamper, Case Tamper, Battery Fault, or Mains Fail.  
The faults mentioned above may affect the overall performance of your alarm control panel, if 
any of the above are displayed you should contact your engineer immediately. 
11.2 Unable to Set 
If ‘unable to set’ is displayed, it indicates 
that an input is already active and the 
area where the input is should be checked 
for open windows, pets, movement etc. 
If the problem cannot be solved contact 
your engineer, or omit the input (page 16)
