Introduction
FREE 50 R: Hands free activator with presence detection signal for external presence detectors.
FREE 50 RS: Hands free activator with presence detection signal and presence detector incorporated (sonar).
In the FREE 50 RS version a sonar is incorporated, it does the function of presence detection. This device operates with ultrasound (not audible) at 42kHz. It can detect little objects at a
few meters and big objects at more distance. For a good detection of the obstacle, this has to be at an angle of 90° respect the sonar (See Installation).
The presence detection signal, free contact input, allows connecting external presence detectors, like photocells or magnetic detectors, and when the device detects a presence it activ-
ates the signal and enables the tag inside the activation field.

Connection
Connect the power supply wire to the 230Vac and connect the 4 signal wire as follows:
Signal Cable colour
Presence Red
- (GND) Black
Sync IN Green
Sync OUT White
In the FREE 50 R version, if the presence detection signal (red) is not used, please join it to the black wire (GND), and the device will always detect presence.
In case of using more than one activator in series (maximum 4), connect the synchronism signal OUT to the synchronism signal IN of the following activator, to avoid interference
between them.
If you only desire to connect one activator join the two synchronism signals IN and OUT.
