Installation Notes
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not fix the sensor to an unstable or vibrating surface.
• Do not install the sensor within 1 m of any lighting, forced air heating, or ventilation equipment.
• Do not install several sensors in parallel near lamps that emit infrared radiation if these lamps are switched via another
PIR switch. This can cause false triggering.
• Make sure that the wires and cables are securely held within the connection terminals.
• Do not connect on a circuit with large inductive loads, as induced spikes can cause false triggering or damage the sensor.
• Protect the sensor by a 6 A MCB or fuse.
• Disconnect the sensor from the circuit before performing insulation testing of the wiring circuit.
