Main risks

• Electric shock or short circuits during installation or when handling cables and terminals.
• Overheating or failure if sensors are covered or unsuitable power supplies are used.
• Falls when working at height, and damage from the device detaching if not securely fixed.
• False alarms or unwanted activations due to poor placement, direct sunlight, draughts, vibrations or proximity to heat sources.
• Damage from moisture, dust or rain in models not designed for outdoor use or damp areas.
• Risk of ingestion or choking from button batteries and small parts.
• Interference from magnets (in magnetic contacts) with pacemakers or other implanted medical devices.
• Accidental puncturing of hidden cables or pipes when drilling during installation.

Safe use

• Switch off the power before connecting, disconnecting or handling cables. Use the power supply specified by the manufacturer.
• Position the sensor at the recommended height and orientation, avoiding direct sunlight, air vents, heating appliances and areas subject to vibration.
• Keep the detection field clear and do not cover the optics or grilles. Do not paint the device.
• Check operation after installation and periodically; adjust sensitivity, timing or detection zones if the model allows.
• Secure the unit with fixings appropriate to the surface. If using adhesive, clean thoroughly and periodically check the bond.
• For magnetic contacts, correctly align the sensor and magnet and avoid nearby sources of strong magnetism.
• With batteries: observe polarity, do not mix types or brands, do not recharge non-rechargeable batteries, and replace them all at the same time when appropriate.
• For work at height, use a stable ladder and avoid overreaching.
• Use the device indoors or outdoors only as appropriate for the model and its protection rating.

Storage and maintenance

• Store sensors in a dry, ventilated place, away from sources of heat, moisture and dust.
• Clean them with a soft, dry cloth. Avoid solvents, compressed air or direct water spray.
• Periodically check the condition of fixings, housings, seals, cables and connectors. Replace damaged parts.
• Regularly check correct operation, especially after relocation or refurbishment of the room.
• Replace the batteries when the device indicates a low level or if you notice reduced range or false alerts. Remove the batteries if it will not be used for an extended period.
• If the model allows, keep the software/firmware up to date following the manufacturer's instructions.
• If the device gets wet, is dropped or suffers an impact, disconnect it, allow it to dry completely and consider replacement if anomalies persist.

Restrictions on use

• Do not use these devices as the sole system for safety-critical functions (e.g., life protection or emergencies). Use dedicated solutions where required.
• Do not install in potentially explosive atmospheres or in areas with continuous condensation unless the model is specifically designed for it.
• Do not modify, drill or open the enclosure, except for the intended access to batteries or fixing points.
• Do not cover or paint the sensors, or install them behind curtains or objects that block detection.
• Keep button batteries and small parts out of reach of children and pets; use secured battery covers.
• Keep magnets and magnetic contacts away from pacemakers or other implants; maintain a safe distance.
• Avoid use near strong sources of interference (powerful motors, RF equipment) if you observe unstable operation.
• Do not expose the device to extreme temperatures or immersion in water unless the model is designed for it.
