8. It is required connect supervisory trouble reporting devices to outputs marked [AC FAIL, LOW BAT] (Fig. 1, pg. 3).
Use 22 AWG to 18 AWG for AC Fail & Low Battery reporting. AC Failure will report in 5 minutes.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on. To delay report 6 hours cut “AC Delay” jumper (Fig. 1b, pg. 3).
9. Please ensure that the cover is secured with the provided Key Lock.
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 Terminal Identification Tables).
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.
Note: Maximum charge current under discharge is 0.7 amp.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if necessary.
