7.  For Access Control Device and Fire Alarm Interface connections see Application Diagrams, pg. 4 and Terminal
 

Identification Chart, pg. 3

8.  Secure enclosure door with the screws supplied to assure proper ground.

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper voltage level 
(see Power Supply Output Specifications Chart, pg. 1).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the 
battery terminal and at the board terminals marked [+ BAT -- ] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharge is 0.40A.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
