Description
The AQD6 series are heavy-duty, self-contained, efficient, clean,
offline switching power supplies, with linear-type performance,
and are jumper selectable between 12 VDC at 6A and 24 VDC
at 6A. The AQD6 series have a dedicated lead acid battery(s)
charger that obtains maximum battery life while providing 12
VDC or 24 VDC uninterruptible power for access control security
systems. The field selectable AC input allows these power
supplies to be powered anywhere in the world. The AQD6
series have exceptional brownout capability with operation down
to 85% of nominal voltage. The AQD6 series have an extensive
filtering system that provides linear output performance, and
they are electronically protected against battery reversal,
shorting, or overloading. Power limited output with thermal
protection is available with Models AQD6-8F, AQD6-8C,
AQD6-16F, AQD6-16C AQD6-8F8R, and AQD6-8C1R; non-
power limited in Model AQD6. Each of these protective features
will self-restore.
NOTE: Before connecting load and battery(s), the 12V/24V jumper
is moved to the desired voltage.

CAUTION
Damage can occur when switched with DC output load.
Proper voltage must be confirmed before connecting
devices.
The AQD6 series are UL Listed and have additional supervisory
features:
Battery disconnect relay when battery(s) are depleted
Set of Form “C” relay contacts that indicate AC power
failure
Set of Form “C” relay contacts that indicate low battery(s)
DC Output is Class II power limited.
Depending on load, low battery trouble indicates 50–75% battery
capacity remaining. Input wiring to the unit should be enclosed
in conduit secured firmly to the enclosure. The AQD6 cannot be
used to power a mercantile bell.
Specifications
AC Input: L, N, G - 3P Terminal block
Safety block with recessed hardware insulation accepts up to
12 AWG
L= Line, N= Neutral, and G = Ground
AC Input .........................................................120–240 VAC / 240W

AC LED Indicator (Panel mounted on the enclosure door)
The AC indicator is a green LED. This LED off with AC at the terminals
would indicate a blown fuse link. A blown AC fuse link would indicate
catastrophic failure and must be returned to the factory for repair.
AC Input Voltage Selection
CAUTION
To prevent damage, the power supply board must be configured for
the proper voltage before applying line voltage.
NOTE: Once the link is cut, there is no conversion back to 120 VAC.
There is a removable link located at the top right of the power supply
board. This link is cut and removed to convert to 240 VAC.
DC Output Voltage Selector Jumper
CAUTION
To prevent damage, the DC load and battery(s) connections are
removed before switching selector switch up or down.
The jumper is slightly left of center near the AC terminal block, and is
marked with “VOLTAGE SELECT 12V / 24V”. The jumper is moved to
the appropriate pins to configure the output voltage.
DC Outputs: 2P Terminal block
NOTE: There is up to a 10-second delay for initial turn on.
Output voltage Nominal ............................................12 VDC / 24 VDC
Output voltage Typical ........................................ AC on 12.5V / 25.0V

Battery Charging: (2P Terminal block marked [–Bat+])
CAUTION
To avoid spark, AC must be applied before connecting battery cable
to battery.
Fault reporting relay rating: 32 VDC, 120 VAC, 1A
The battery charger is precision set to float charge 12V or 24V sealed or
wet lead acid batteries. A 12-inch battery cable assembly is provided
that plugs from module to battery: Red (+), Black (–) Neg.
Battery(s), any type of lead acid ......................12V / 24V, 4 AH–40 AH

UL Approvals for AQD6
UL 294, 6th Edition –Access Control System Unit
Endurance Test Level 1
Attack Test Level 1
Battery Standby Test Level 4
UL 603 –Power supplies for Use with Burglar-Alarm Systems
UL 1481 –Power Supplies for Fire-Protective Signaling Systems
ULC S318-96 –Power supplies for Burglar Alarm Systems
ULC S533-02 –Standard for Egress Door Securing and Releasing
Devices
For ULC-S318-96 compliance, the power supply battery fail line must be
connected to and monitored by a control panel trouble zone.
NOTE 1: The AQD6 uses a standard power supply enclosure, not an
attack proof’ enclosure. As such, the AQD6 should not be
used to power a mercantile bell.
NOTE 2: When using a battery that is not housed inside the power
supply enclosure, the battery leads require protection from
the enclosure via the use of conduit.
NOTE 3: When using the AQD6B in another enclosure, minimum
standard spacing between live electrical circuits shall be
taken into account.

Maintenance
The power supply and stand by battery(s) should be tested at least once a year as follows:
1. CHECK LED’s for normal state:AC ON Green, Trouble Normal ON Green, DC ON Red.
2. CHECK output voltage with normal load (assures proper voltage to float charge batteries): For 12V setting, voltage should
read between 13.6 VDC and 13.8 VDC; and for 24V setting, voltage should read between 27.1 VDC and 27.6 VDC.
3. DISCONNECT AC input: AC LED should be off, and all other LED’s should remain normal.
4. CHECK DC output to be above 12.0 VDC for 12V setting and 24.0 VDC for 24V setting (checks standby batteries to be
operational).
5. APPLY AC and VERIFY AC LED ON.
Battery Selection
The table below shows typical standby time in hours for various loads and batteries. The table works for either 12 VDC or 24 VDC.
The AQD6 was evaluated at UL with a 75 Ah sealed lead acid battery.
