Powering the Unit
To charge the battery, plug the supplied charging cable into the USB-mini socket [14] and then plug
into any full-sized USB socket, for example on a computer or phone charger, or alternatively plug a
dc power supply into the auxiliary power socket [15]. Prior to using an auxiliary power source, it is
important to check that its polarity and voltage are in accordance with the specifications given at the
end of this booklet.
Irrespective of the charging source, the charging LED [13] lights green and once fully charged, the LED
is extinguished. Charging takes approximately 3 hours if the battery is completely flat and the unit
may be used as normal while charging. If the charging LED should flash red during use and the unit
emit short beeps, it’s time to recharge.
Connecting the unit to devices
FREEDOM
may be connected to up to four devices via the four sockets [5-8] and the supplied cables.
Occasionally you may encounter a device which has a switch input which uses a connector other than a
3.5mm socket, in which case one of the supplied cables can be adapted. More cables can be purchased
from Pretorian- the part number is E070010. You do not need to consider the way in which each
respective device is connected to ground or mains earth since each socket in
FREEDOM
is electrically
isolated from the others.
The unit is capable of switching up to 30V and must
NEVER
be used to switch anything above this
voltage, otherwise personal injury or damage may occur.
When connecting your devices to
FREEDOM
, carefully consider which is the most important to have
continued access to, should the battery become flat or the power fail. Ensure that this device is
plugged into socket number 1. In most cases this will be device which may be used to call for attention
so that you are able to get the unit charged, such as a warden call system.
Limiting the Number of Active Devices
Although
FREEDOM
is able to switch between four devices, in many cases it will be used with fewer
than four. To avoid the need to scan to unused devices, the number of active devices may be selected
anywhere between two and four inclusive. By default the unit is supplied to switch between all four
devices, but if you wish to limit that number, press the Devices button [11] repeatedly until the correct
number of LEDs [1-4] are lit*. After a few seconds of there being no further presses of the Devices
button, the LEDs are extinguished and the settings saved.
Devices 1 and 2 are always in use and 3 and/or 4 may optionally be disabled.
*Note that the LEDs blink to help distinguish between this and normal operation.
Connecting the unit to switches
Next connect your switch to the Main Switch socket [16]. Then decide whether you wish to use this
switch to select which device it is connected to, or whether you would like to use a second switch for
this purpose. If you would prefer to use a second switch, plug it into the Scan Switch socket [17].
