APS-300 Series Power Supply/Charger Installation Guide
The APS-300 with standby battery(s) provides an uninterruptible 9.8VDC-13.7VDC or 20.0VDC-27.5VDC power source. When
use with optional Power Distribution modules PD4C or PDFT, it can provide multiple fused outputs or Fire Interface. The DC
output on the APS-300 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. Using 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 by shifting the jumper J1 for 12VDC or 24VDC.
Only change output voltage when AC is OFF and
Batteries are not connected
. The APS-300 Series has a continuous output rating of 9.8VDC-13.7VDC at 2.8 Amps or
20.0VDC-27.5VDC at 1.4 Amps. If a power distribution product is 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 separated by 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 supervision is desired, 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 calculation to ensure your power requirements are within the
unit’s continuous power rating. 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. 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 optional power distribution board PD4C 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.
12. For installation and use of optional PD4C and PDFT, see separate enclosed instructions.
CAUTION: 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.
