What it is:

The power distribution board centralizes the power sources for multiple
devices, such as CCTV cameras and/or electromagnetic locks, providing
separate fusing on each output, so that problems with one set of devices may
be isolated from the other devices.

Installation:

1. Mount the PC board in the desired location or enclosure and must be
easily accessible for future sevicing.

NOTE: DO NOT USE METAL SPACERS TO MOUNT THE PC BOARD.

2. Connect the output wires of the power supply (transformer or battery) to
the PC board's terminals marked "INPUT" (see Fig.1).
NOTE: If using DC voltage, correct polarity must be observed.

3. Check the main switch, it should be in the OFF position. Connect the
power input wires for the devices to be powered to the PC board (see fig.

1). The terminals marked “P” are for positive wires, and “N” are for
negative wires. Each output consists of one “P” terminal and one “N”
terminal. Run wire pairs from the PC board through or along the wall to
where the devices are located.

NOTE: For best results and to minimize voltage drop, these wires
should be a minimum of 18-gauge in thickness.

4. Turn the main switch ON. The green LED on the PC board will light to show
that power is present. The four or nine red LEDs on the PC board will light
to show the status of each terminal pair, with ON meaning that the
terminal pair is working correctly.

5. Test the voltage output at the end of each wire pair to see if there is
significant voltage drop. The voltage output reading of all wire pairs should
be approximately the same.

Voltage drop can occur for one of three reasons:
a. The wire is too thin. That is why 18-gauge wire is recommended.

b. The wire has run a long distance. If one or more of the wire pairs is

showing significant voltage drop compared to the others, either shorten
the length of the wire pairs with the voltage drop, or lengthen the other
wire pairs so that there is a similar voltage output reading on all wire
pairs.

c. A large number of devices connected to the PC board is causing

excessive power drain across all the outputs.

6. Turn the main switch OFF and connect wire pairs to their respective devices.

NOTE: Using a voltage output in excess of the specified voltage level of
a device may cause damage.

IMPORTANT: Total current drain for any one terminal must not exceed the
output fuse rating or the output PTC fuse will blow. Total current for all terminals must
not exceed the PC board's main fuse rating or the power supply total current capacity.
The main fuse should be chosen to reflect the limits of the power source, such as
transformer or battery. The main fuse amperage rating is typically set at about 1 Amp
above the continuous current limit, so that transient surges will not cause it to blow
unnecessarily. Check the specifications for your power supply to ensure the proper
rating for the main fuse.
