Activation + Safety Infrared Sensor
3H-IR14C(EN16005)(Successor model of HR94D1-C1)

Cost efficient door opening & pedestrian safety in one compact sensor.
3H-IR14C is further enhanced Row 1 detection (12 spots), is made communication with controller possible and is improved dust & water proof.

*EN16005 is the regulations of power operated pedestrian door sets in all CEN member countries.

*For Users of HR94D1-C1, Hotron recommends the replacement to 3H-IR14C since HR94D1-C1 is discontinued.


Active Infrared Sensor

Active Infrared sensors take a snap shot of the reflection levels from the ground. Any change in the properties of the reflected wave will indicate that a person or object is in the detection area.
