MaximalDV Series Overview:
Altronix MaximalDV Access Power/Controllers distribute and switch power to access control systems and
accessories. They convert a 220VAC (working range 198VAC - 256VAC), 50/60Hz input into sixteen (16)
independently controlled 12VDC or 24VDC PTC protected outputs. The outputs are activated by an open col-
lector 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.

10. Stand-by Battery Connections (Fig. 3, pg. 8):
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 (Fig. 3a, pg. 8). Use two (2) 12VDC batteries wired in
series for 24VDC operation.
11. Battery and AC Supervision outputs (Figs. 3-4, pgs. 8-9):
It is required to connect supervisory trouble reporting devices to outputs marked [AC Fail, BAT FAIL]
and [Power Fail] supervisory relay outputs marked [NC, C, NO] to appropriate notification devices.
Use 22 AWG to 18 AWG for AC Fail & Low/No Battery reporting.
12. Installation of tamper switch (Figs. 3-4, pgs. 8-9):
Mount UL Listed tamper switch (Honeywell Model 112 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
(Figs. 3b and 4a, pgs. 8-9). Connect tamper switch wiring to the Access Control Panel input or the
appropriate reporting device. To activate alarm signal open the door of the enclosure.
13. Multiple power supply inputs (Fig. 2, pg. 7):
When using an additional external power supply, jumpers J1 and J2 located on corresponding ACM8CB
boards must be cut (Fig. 2c, 2d, pg. 7 and Fig. 7, pg. 12). Connect power for the ACM8CB boards to the
terminals marked [– Power +] and connect power for the access control devices to the terminals marked
[– Control +]. When using DC power supplies polarity must be observed. When using AC power supplies
polarity needs not to be observed (Fig. 2d, pg. 7). All field wiring connections must be made employing
suitable gauge CM or FPL jacketed wire (or equivalent substitute) (Figs. 5a and 6a, pgs. 10-11).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
FACP Supervision: To ensure 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. 10, pg. 13) or Normally Closed (Fig. 12, pg. 14) 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. 7).
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 ensure that there is no break in the battery connection wires.

NEC Power-Limited Wiring Requirements for Maximal3DV:
Power-limited and non power-limited circuit wiring must remain separated in the cabinet. All power-limited
circuit wiring must remain at least 0.25” away from any non power-limited circuit wiring. Furthermore, all
power-limited circuit wiring and non power-limited circuit wiring must enter and exit the cabinet through differ-
ent conduits. One such example of this is shown below. Your specific application may require different conduit
knockouts to be used. Any conduit knockouts may be used. For power-limited applications use of conduit is
optional. All field wiring connections must be made employing suitable gauge CM or FPL jacketed wire (or
equivalent substitute).
Note: Refer to wire handling drawing below for the proper way to install the CM or FPL jacketed wire (Fig. 5a).
