S300RPTU Hand tool communicates via infrared with 800 range detectors allowing to adjust the sensitivity, see the production date and the last maintenance, empower/cancel the LEDs blinking, realize an automatic test and focus the sensor to obtain a directioning by using the module in ZDU zone. Can be configured to operate in a infrared mode for short distances, 30mm, and via radio for distances up to 4,5m. Requires S300SAT placed on the detector to realize radio communication for distances from 30mm to 4,5 meters.
