Fire Alarm Interface connection options:
a . Connect the FACP trigger input to the removable terminals marked FACP1 and FACP2 . When using
the polarity reversal from an FACP signaling circuit, connect the negative [–] to the terminal marked
FACP1 and the positive to the terminal marked FACP2 (polarity is in alarm condition)
(Rack Mechanical Drawing and Dimensions pg. 12) .
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. 12) .
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 ensure that there is no break in the battery
connection wires .
