Disconnect the mains power. Verify that the green Mains LED extinguishes and the yellows Fault LED starts 
to pulse (indicating that the PSU is running from its standby batteries). 

15)

 

If  connected,  verify  that  the  EPS  Fault  monitor  shows  an 

open

  contact  and  the  GEN  PSU  Fault  monitor 

shows a 

closed

 contact. 

16)

 

Perform a full functional test of system including full alarm condition. Verify that the standby batteries can 
support the system load. Note: ensure batteries have sufficient charge. 

Final 

17)

 

Reconnect the mains. Verify that the green Mains LED illuminates and the yellow Fault LED extinguishes. 

18)

 

If  connected,  verify  that  the  EPS  Fault  monitor  shows  a 

closed

  contact  and  the  GEN  PSU  Fault  monitor 

shows a 

closed

 contact. 

 

NOTE: Batteries must be connected before mains power is applied to enable the 
batteries to be utilised. When replacing batteries, re-connect new batteries and then 
cycle the mains power.

In the event of loss of mains, a battery fault or a GEN PSU fault, the corresponding Fault signal contacts will 
open.  
 
If  the  output  of  the  PSU  fails,  the  cause  of  the  failure  should  be  investigated  e.g.  short  circuit  load, 
connection of a deeply discharged battery. The fault should be rectified before restoring power to the PSU. If 
any of the fuses require replacing, ensure the correct fuse rating and type is used.

This unit is intended for use by Service Personnel only.  There are NO USER SERVICEABLE parts inside. 
 
There is no regular maintenance required of the PSU other than periodic testing, and replacement of the 
standby battery.  

Reference should be made to the battery manufacturer's documentation to determine 

typical/expected battery life with a view to periodic replacement of the battery.
