MaximalE Installation Instructions:

Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/ANSI, and with all local codes and
authorities having jurisdiction. Product is intended for indoor use only.

Power Supply Board Terminal Identification (pg. 5)
Power Supply Stand-by Battery Specifications (pg. 5)
Power Supply Board LED Diagnostics (pg. 6)
Power Supply Board Output Voltage Settings (pg. 6)

1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top three keyholes in the
enclosure. Install three upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the three upper screws, level and secure. Mark the position of the lower three holes. Remove the
enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s upper keyholes over the three
upper screws. Install the three lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 13).

2. The power supply is pre-wired to the ground (chassis). Connect main incoming ground to the provided green
grounding conductor lead. Connect unswitched AC power (115VAC 60Hz) to terminals marked [L, N] on both
power supply boards. Use 14 AWG or larger for all power connections. (Fig. 2, pg. 7).
Keep power limited wiring separate from non-power limited wiring. Minimum .25” spacing must be provided.

3. Select desired DC output voltage by setting SW1 to the appropriate position, (Maximal11E, Maximal13E,
Maximal33E, Maximal35E and Maximal37E) (Fig. 1, pg. 6). Maximal55E power supplies are factory set at 12VDC.
Maximal77E power supplies are factory set at 24VDC. Maximal75E power supplies are factory set at 12VDC and
24VDC, (Power Supply Board Stand-by Battery Specifications, pg. 5).

4. Measure the output voltage of the unit before connecting any devices to ensure proper operation.
Improper or high voltage will damage these devices.

5. Connect devices to be powered to terminals marked [+ DC -] (Fig. 2, pg. 7).

6. 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.
Connect battery to terminals marked [+ BAT -- ] (Figs. 2-7, pgs. 7-12).
Use two (2) 12VDC batteries connected in series for 24VDC operation (battery leads included).

7. Battery and AC Supervision outputs: It is required to connect supervisory trouble reporting devices to outputs marked
[AC Fail, BAT FAIL] supervisory relay outputs marked [NC, C, NO] to appropriate visual
notification devices. Use 22 AWG to 18 AWG for AC Fail & Low/No Battery reporting (Fig. 2a, pgs. 7).

8. Mount UL Listed tamper switch (Not Included) (Sentrol model 3012 or equivalent) at the top of the enclosure.
Slide the tamper switch bracket onto the edge of the enclosure approximately 2” from the right side (Fig. 2b, pg. 7).
Connect tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device.
To activate alarm signal open the door of the enclosure.

9. Please insure 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

(Power Supply Stand-by Battery Specifications, 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 insure that there is no break in the battery
connection wires.
Note: AL400ULXB, AL600ULXB and AL1012ULXB (Power Supply Board) maximum charge current is .7 amp.
AL1024ULXB (Power Supply Board) maximum charge current is 3.6 amp.
Expected battery life is 5 years, however it is recommended to change batteries within 4 years or less if necessary.

Function/Description

L. G, N Connect 115VAC 60Hz to these terminals: L to hot, N to neutral, G to ground.

- DC + Refer to Maximal Series Configuration Chart, pg. 3.

AC FAIL

NC, C, NO

Indicates loss of AC power. To meet with UL requirements it is mandatory to connect visual notification
devices, connecting audible notification devices is optional. Relay normally energized when AC power is
present. Contact rating 1 amp @ 28VDC. AC or brownout fail is reported 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 minutes.
Battery reconnection is reported within 1 minute.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC.
24VDC output threshold set @ approximately 21VDC.
