External detector
The detector is the actual eye that receives the IR-signal. There is an internal detector on the
circuit board of the receiver. The colors of the wires are to be connected as shown in the
figure when connecting an external detector. Make sure that the wires are correctly
connected when connecting a detector.
There are two terminals for connecting external detectors. It is possible to connect more than
two external detectors by connecting them in parallel on the existing terminals. A maximum
of 5 pcs can be connected.
Note! The range will be reduced if the detector eye is covered or hidden in some way, for
example by curtains or furniture.
Connecting control switch
There are two terminals for connection of control switches to Gewa Andromeda. A control
switch is connected to the terminal for external detectors. For example, an elbow switch can
be connected.
Note! When the relay is activated by a control switch, the relay is held about 0.5 seconds
after releasing the control switch.
Relay Connection
The receiver has four relays with alternating relay contacts. Inductive loads, such as motors
and relays, should be connected through a disturbance filter. The maximum relay loading is
specified in the Technical specifications.
Power supply
The receiver is powered with 12-24V AC/DC (-10% - +20%).
