AL300ULXD - 3 -
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
(Power Supply Output Selection chart).
Battery Test: Under normal load conditions, check that the battery is fully charged, check specified voltage both at bat-
tery 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 discharges is 600mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
LED Diagnostics:
Red (DC) Green (AC) Power Supply Status
ON
ON Normal operating condition.
ON OFF Loss of AC, Stand-by battery supplying power.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or no stand-by battery. No Dc output.
Terminal Identification:
Terminal Legend Function/Description
AC/AC
Low voltage AC input (28VAC / 100VA).
+ DC – 12VDC / 24VDC @ 2.5 amp continuous power-limited output.
AC Fail
NC, NO, C Indicates loss of AC power, e.g. connect to audible device or alarm panel. Relay normally ener-
gized when AC power is present. Contact rating 1 amp @ 28VDC. AC or brownout fail is report-
ed within 1 minute of event.
Bat Fail
NC, C, NO Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized when DC
power is present. Contact rating 1 amp @ 28VDC. A removed battery is reported within 5 min-
utes. Battery reconnection is reported within 1 minute.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC,
24VDC output threshold set @ approximately 21VDC.
– BAT + Stand-by battery connections. Maximum charge current 0.7 amp.
