AQD3 , Power Supply/Charger Installation Guide
The AQD3 with standby battery(s) provide an uninterruptible 9.8Vdc-13.7Vdc or 20.0Vdc-27.5Vdc power source.
The Power Distribution modules provide multiple fused outputs, Fire Interface, and Access control Interface. The DC
output on the AQD3 power supply is Power Limited. This makes all subsequent outputs power limited.
1. The installation of this power supply shall comply with the National Electrical Code (ANSI/NPFA 70), the
Canadian Electrical Code, Part 1, and be in accordance with any additional requirements imposed by the local
authority having jurisdiction.
2. For use in Indoor Location Only, Mount the Power Supply in desired location. Utilizing the two keyholes on the
upper end and the two or three holes along the bottom, mount the enclosure to the wall with appropriate
fasteners.
3. Select output voltage J1 for 12vdc or 24vdc. Only change output voltage when AC is OFF and Batteries are not
connected. The AQD3 has a continuous output rating of 9.8Vdc-13.7Vdc at 2.8 Amps or 20.0Vdc-27.5Vdc at 1.4
Amps. If any distribution products are used, the total current draw of these devices must be subtracted from the
available current rating. See selection table below or individual data sheets. Connect AC Line voltage, 110-
240vac with Earth Ground to the Orange AC input Terminal block. This wiring must be run in separate metal
enclosed wiring system only. Note, Ensure all wiring is of appropriate gauge for device being powered. All
Power Limited circuits must be routed a minimum of .25” from Non-power Limited circuits.
4. Connect DC devices to the Output Terminals. Observe polarity. On the distribution boards Negative is identified
with a (-) or (COM). The Positive is identified with (+) or (HOT). Exit the DC wiring out any of the other available
knock outs keeping all the low voltage wiring away from the high voltage wiring and battery leads.
5. If AQD3 series connect N/C Tamper switch and AC fail form “C” contacts to Security system for annunciation.
6. Add the current draw of the distribution boards to your load. Always check the spec sheet; but as a rule, each
LED draws 6ma and each relay draws 20ma.
7. Confirm with Amp meter that your total continuous current conforms to the output current rating and that each
output rating is proper for the powered device(s).
8. On the AQD3 models connect AC fail contacts to annunciate AC Status condition.
9. Connect appropriate standby battery(s). Remove AC and confirm battery output to test standby battery(s). Mark
installation date on Battery with permanent marker.
10. Each protected output on the multi-output distribution boards has a Green Status LED. Green ON indicates
ready.
11. To reset a tripped PTC Circuit Breaker, you may have to turn power off on outputs, or remove faulted circuit
output for up to 2 minutes. This allows the PTC re-settable circuit breaker to cool and reset to its normal “ON”
condition.
CAUTION Reduce the risk of fire replace fuses as marked
When calculated your total DC current be sure to add the current of any distributions options you are using.
Be sure your normal continuous DC current draw does not exceed the marked rating of the supply.
Select 12/24 J1 only with AC off and Batteries disconnected.
