Dycon D1545 Installation Manual

Installation Manual for a
D1545 5A, Multi-Indicator, General Purpose
Power Supply

Installation

To protect the battery on install, mains power is required to start the PSU. Once the mains is
connected, the battery will automatically charge and provide stand-by power.
Mount the metal enclosure onto the wall.
Connect the Live, Earth and Neutral terminals to an un-switched fused spur.
Connect the tamper outputs to the control panel as appropriate (see control panel manuals for details).
Connect the 12v power output to the system. NOW fit the battery, not before!
Switch on the AC supply and confirm that the green LED marked "230V AC" is lit.

External power supply (AC supply)

The power supply has a three-way terminal block for Live, Earth and Neutral connections, and is protected by
a 20mm anti-surge fuse. Mains earth is isolated from the 0V output, although, when supplied boxed, mains
earth is connected to the metal enclosure.

Tamper output

This voltage-free output is connected to the tamper switch. These terminals will be shorted when the tamper
switch is closed.

12V power output

Terminal blocks are provided to connect to the system. The green 230V AC LED or orange standby LED
indicates that the 12V is available from these terminal blocks.

. Auxiliary power supply (batteries)

These power supplies are compatible with 7AH or 8AH Sealed Lead Acid or Gel batteries which are connected
to the "BATT" terminals. The orange standby LED, marked with a battery symbol, indicates when AC power is
off and power is being supplied by the batteries.
If two batteries are used, they must be connected in parallel.

Output protection

The output is protected by resettable fuse. Should the output be overloaded and the fuse trip, the red fuse
fault LED, marked with a battery symbol, will be lit. The fault can be reset by removing the short and re-
applying power after a minute to allow the fuse to cool.

Battery protection

The batteries and electronic circuitry are protected against reverse polarity connection by a self- resetting
electronic fuse.

Output splitters

An output splitter can be connected to a D1545's 12VDC power output to provide up to 4 or 8 individually fused
outputs, e.g., a D1545 could support outputs 1 to 6 = ½ A and outputs 7 and 8 = 1A (5A in total). A Dycon D15X8
8-way splitter is supplied fitted with 8 fuses rated at ½ Amp, plus 2 fuses rated at 1 Amp in a separate spares
bag. You may fit any combination of fuses, provided that the overall load does not exceed that provided by the
power supply. A red LED is provided for each output, which lights if the relevant fuse ruptures. In addition, a
9 th LED is provided which lights when the input voltage is present. A 2-way Molex connector is provided to
connect a remote LED to indicate if ANY fuse fails.
