AL1012X220 series
Note:
When servicing the unit, AC mains should be removed.
5. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the
loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
6. Connect appropriate signaling notification devices to terminals marked [AC FAIL] and [BAT FAIL]
(Fig. 1, pg. 5)
supervisory relay outputs.
Note:
When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used to
provide a visual indication of AC power on.
Wiring:
USE 14 AWG or larger for all power connections.
Note:
Take care to keep power-limited circuits separate from non power-limited wiring (220VAC, Battery).
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.
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified voltage both at the
battery 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 0.7A.
Note:
Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

AL1012XB220 - Power Supply Board
Terminal Legend Function/Description
L, N
Connect 220VAC (working range 198VAC - 256VAC), 50/60Hz to these terminals:
L to Hot, N to Neutral. Do not use the [G] terminal.
--- DC +
12VDC @ 10A continuous non power-limited output.
AC FAIL
NC, C, NO
Indicates loss of AC power, e.g. connect to annuciator/alarm panel. Relay normally energized when
AC power is present. Contact rating 1A @ 30VDC. AC Fail condition will report approximately
one (1) minute after the loss of AC. To delay report for 6 hours cut jumper J1 on the Power Supply
Board (AC trouble output delay option). If this mode is selected, the Power Supply Board must be
reset by removing all power to it for 30 seconds.
BAT FAIL
NO, C, NC
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized when DC
power is present. Contact rating 1A @ 30VDC. Low battery conditions will report approximately
10.5VDC. Battery presence detection will report approximately 1 minute after battery remains unde-
tected (missing or removed).
+ BAT ---
Stand-by battery connections. Maximum charge rate 0.7A.
