Overview
What it is
PrimeMotion B is a 24.125 GHz microwave (radar) motion detector that mounts above an automatic pedestrian door and sends an opening pulse to the door controller. It is the configurable version of the PrimeMotion range, set with DIP switches and a potentiometer.
What it is used for
Bircher shows PrimeMotion for opening sliding doors, including tall doors and wide telescopic sliding doors where one detector per side is enough. The Sensorama brochure also lists swing and revolving doors.
Key features
- Direction recognition (forward only or both directions)
- CTO (cross traffic optimisation) and swing filter to reduce unwanted openings
- Door and electromagnetic interference filter for sites with fluorescent lamps
- Slow motion detection enabled at the factory
- Wide field up to 4.0 x 2.0 m or narrow field up to 2.0 x 4.0 m at 2.2 m, changed by rotating the radar module 90°
- Output active (NO) or passive (NC) by DIP switch
Buying considerations
The manual states PrimeMotion B is not a safety component under the EU Machinery Directive. Pair it with a presence sensor if the door needs protection. PrimeMotion C is the simpler model without DIP switch functions.
Installation considerations
Mounting height is 1.8 to 4 m. The radar module tilts and swivels to aim the field. Housing protection is IP54; a PMCAP rain cap is available. Operate from SELV (safety extra-low voltage) and earth the door drive and transom.
Compatibility
Supply 11.5 to 32 V DC or 12 to 28 V AC. The semiconductor relay output switches up to 48 V AC/DC and 80 mA, which suits common door controller activation inputs.
