Terminal Identification - Altronix ULXB Series Installation Manual

Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (120VAC, Battery).
Unit should be tested at least once a year for the proper operation as follows:

ULXB Power Supply/Chargers
Under normal load conditions, the DC output voltage should be checked for proper
voltage level.
Under normal load conditions check that the battery is fully charged, check specified
voltage (12VDC @ 13.2 or 24VDC @ 26.4) both at the battery terminal and at the
board terminals marked [– BAT +] to ensure that there is no break in the battery
connection wires.
Disconnect existing batteries. Connect battery to the terminals marked [– BAT +].
Use two (2) 12VDC batteries connected in series for 24VDC operation.

24VDC @ 10A (UL294) (Non Power-Limited output) (Fig. 1d, pg. 4).
Used to notify loss of AC power, e.g.connect to audible device or alarm panel.
Relay normally energized when AC power is present. Contact rating 1A @ 28VDC.
AC or brownout fail is reported within 1 minute of event.
To delay reporting for up to 6 hrs., cut "AC Delay" jumper and reset power to unit
(Fig. 1b, pg. 4).
Used to indicate low battery condition, e.g. connect to alarm panel.
Relay normally energized when DC power is present. Contact rating 1A @ 28VDC.
A removed battery is reported within 1 minute.
Battery reconnection is reported within 1 minute.
Low battery threshold: approximately 21VDC (Fig. 1b, pg. 4).
Stand-by battery connections (Fig. 1c, pg. 4).
AL400ULXB2, AL600ULXB, AL1012ULXB maximum charge current 0.7A.
AL1024ULXB2 maximum charge current 3.6A.
