MaximalD Series Overview:

Maximal Access Power/Controllers distribute and switch power to access control systems and accessories. They con­vert a 115VAC 60Hz input into sixteen (16) independently controlled 12VDC or 24VDC Class 2 Rated PTC protected
power-limited outputs. These Fail-Safe/Fail-Secure power outputs may be converted to dry form “C” contacts. The outputs
are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Keypad,
Push Button, REX PIR, etc. Units will route power to a variety of access control hardware devices including: Mag Locks,
Electric Strikes, Magnetic Door Holders, etc. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may
be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the
sixteen (16) outputs. All interconnecting equipment must be UL Listed.

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.18).

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.

Keep power-limited wiring separate from non power-limited wiring. Minimum .25” spacing must be provided

(Figs. 6-9, pgs. 13-16).

3. Select desired DC output voltage by setting SW1 to the appropriate position on the power supply board
(Maximal11D and Maximal33D), (Fig. 1, pg. 9). Maximal55D power supply is factory set at 12VDC.
Maximal77D power supply is factory set at 24VDC. Maximal75D consists of one (1) power supply board that is
factory set at 12VDC, and one (1) power supply board that is factory set at 24VDC.

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. Output options (Fig. 2, pg. 9):
The unit will provide either sixteen (16) switched power outputs, sixteen (16) dry form “C” outputs, or any
combination of both switched power and form “C” outputs.

- 4 - Maximal11D/Maximal33D/Maximal55D/Maximal77D/Maximal75D Access Power Controllers (PTC)

(a) Fail-Safe Switched Power outputs:

For Fail-Safe operation connect the positive (+) input of the access control devices to terminal marked [NC].
Connect the negative (-) input of the access control devices to terminal marked [COM].
(b) Fail-Secure Switched Power outputs:
For Fail-Secure operation connect the positive (+) input of the access control devices to terminal marked [NO].
Connect the negative (-) input of the access control devices to terminal marked [COM].

(c) Form “C” outputs:

When form “C” outputs are desired the corresponding output PTCs (1-8) of each ACM8CB board must be removed.

6. Auxiliary Power outputs (unswitched):
Connect access control devices that require constant power to terminals marked [C] positive (+) and [COM] negative (-).

7. Input trigger options (Fig. 2, pg. 9):

(a) Normally Open [NO] input trigger:

Inputs 1-8 are activated by normally open or open collector sink inputs.

 Connectaccesscontrolpaneloutputs,keypads,pushbuttons,REXPIRs,etc.toterminalsmarked[IN]and[GND].

(b) Open Collector Sink inputs:

Connect the access control panel open collector sink positive (+) to terminals marked [IN] and the negative (-) to

 terminalsmarked[GND].

8. Fire Alarm Interface options (Figs. 10-15, pg. 17):
A normally closed [NC] or normally open [NO] input trigger from a fire alarm control panel or a polarity reversal
input from an FACP signaling circuit will affect selected outputs. To enable FACP Disconnect for an output
open the corresponding switch(es) [SW1-SW8] on each ACM8CB board. To disable FACP disconnect for an
output close the corresponding switch(es) [SW1-SW8] on each ACM8CB board.

(a) Normally Open [NO] input:

For non-latching hook-up refer to (Fig. 12, pg. 17). For latching hook-up refer to (Fig. 13, pg. 17).

(b) Normally Closed [NC] input:

For non-latching hook-up refer to (Fig. 14, pg. 17). For latching hook-up refer to (Fig. 15, pg. 17).

(c) FACP Signaling Circuit input trigger:

Connect the positive (+) and negative (-) from the FACP signaling circuit output to the terminals marked [+ INP -].
Connect the FACP EOL to the terminals marked [+ RET -] (polarity is referenced in an alarm condition).
Jumper J3 must be cut (Fig. 11, pg. 17).

9. FACP Dry form “C” output (Fig. 2a, pg. 9):
FACP form “C” contacts can be use to trigger reporting or signaling devices. These contact switch
upon a fire alarm input trigger to the ACM8CB boards.

10. Stand-by Battery Connections (Figs. 3-5, pgs. 10-12):
For Access Control applications batteries are optional. If batteries are not used a loss of AC will result in the loss of
output voltage. Batteries must be lead acid or gel type. Connect one (1) 12VDC battery to the terminals marked
[+ BAT -] for 12VDC operation (Figs. 3, 5, pgs. 10, 12). Use two (2) 12VDC batteries wired in series for
24VDC operation (Figs. 3-5, pgs. 10-12).

11. Battery and AC Supervision outputs (Figs. 3-5, pgs. 10-12):
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.

12. Installation of tamper switch (Not Included) (Figs. 3a, 4a, 5a, pgs. 10-12):
Mount UL Listed tamper switch (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. 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.

13. Multiple power supply inputs (Fig. 2, pg. 9):
When using an additional UL Listed external power supply, jumpers J1 and J2 located on corresponding
ACM8CB boards must be cut (Fig. 2b, pg. 9 & Fig. 10, pg. 17). Connect external UL Listed power-limited access
control power supply to the terminals marked [- Power +] (only applicable on Maximal11D). When using DC power

supplies polarity must be observed. When using AC power supplies polarity need not be observed. All field wiring
connections must be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute),
(Fig. 6a-9a, pgs. 13-16).

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:
FACP Supervision: To insure proper connection and operation of the Fire Alarm disconnect hookup. Please follow the
appropriate procedure below:
Normally Open Input: Placing a short between terminals marked [T] and [+ INP] will trigger the Fire Alarm
Disconnect. Remove the short to reset.
Normally Closed Input: Remove the wire from terminal marked [INP -- ] will trigger the Fire Alarm
Disconnect. Replace the wire to terminal marked [INP -- ] to reset.
FACP Signal Circuit Input: It is necessary to trigger the Fire Alarm System.

 InalloftheabovescenariosthegreenTRGLEDoftheACM8CBswillilluminate.Alloutputsselectedfor

Fire Alarm Disconnect will activate releasing locking devices.
Note: All outputs [OUT 1 - OUT 8] must be in a normal (de-energized) condition prior to testing. When the unit is
configured for Normally Open (Fig. 13, pg. 17) or Normally Closed (Fig. 15, pg. 17) latching operation it is
necessary to reset the Fire Alarm Disconnect by activating the Normally Closed reset switch.
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level

(Power Supply Board Stand-by Battery Specifications, pg. 8).

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 0.7 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.
