b. For a latching fire alarm interface connect a normally [NO] reset switch to the removable terminals
marked [REST] and [GND] (Figs. 6-11, pg. 9).
19. Set the power disconnect circuit breaker to the ON position (Fig. 15a, pg. 11).
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
(Output Voltage and Stand-by Specification Charts, pg. 5).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at the battery
terminals and at the board terminals marked [– BAT +] to insure that there is no break in the battery connection wires.
