Frequently Asked Questions

What is the difference between a PIR sensor and a photocell sensor?

A PIR sensor detects movement using infrared, so it controls lights or alarms when someone moves nearby. A photocell measures light levels and switches circuits on or off according to ambient daylight.

Can PIR motion sensors be used for both indoor and outdoor lighting control?

Yes, PIR motion sensors can be used indoors and outdoors, provided the product states it is designed for the environment and has an appropriate IP rating for external installations.

How should I position a PIR sensor to get reliable motion detection?

Aim the sensor so it covers the main walking paths, avoiding obstructions like tall furniture. Mount at the recommended height and angle to reduce blind spots and unwanted triggers from adjacent areas.

Do PIR sensors work with LED lighting and low-energy lamps?

Yes, many PIR sensors work with LED and low-energy lighting, but you should check the maximum load type and rating to ensure compatibility with the lighting circuit and any drivers or transformers.

What does the IP rating on a PIR or photocell mean?

The IP rating shows how protected the device is against dust and water ingress. Outdoor or exposed locations usually require a higher IP rating than sheltered indoor areas or recessed installations.

Can I adjust the time delay and sensitivity on PIR sensors?

Yes, most PIR units have adjustable controls for time delay, sensitivity and sometimes light level. These settings allow fine-tuning so lights stay on long enough without causing unnecessary operation.

What is the purpose of using a photocell on exterior lighting?

A photocell allows lights to come on automatically at low light levels and switch off again during daylight, helping keep outdoor areas illuminated at night without manual intervention or additional timers.

Why does my PIR-controlled light keep turning on with no one around?

This can be caused by oversensitive settings, moving branches, pets, traffic or heat sources. Reducing sensitivity, adjusting the detection angle or repositioning the unit often helps minimise false activations.

Can PIR sensors be used to control ventilation fans as well as lighting?

Yes, many PIR devices can trigger fans if wired correctly within their load rating. Always check the product documentation and, if unsure, consult a qualified electrician before installation.

Do PIR sensors need a neutral connection to work?

Some PIRs require a neutral conductor, while others are two-wire designs that do not. The wiring requirement is shown in the product specifications and installation instructions provided by the manufacturer.

How do I prevent a photocell from being affected by nearby lighting?

Position the sensor so it does not directly see the light it controls. Shielding or adjusting the mounting point can prevent feedback where the fitting turns itself on and off repeatedly.

Is professional installation recommended for PIRs and photocells?

Yes, hard-wired units must comply with electrical regulations, so many customers use a qualified electrician. This helps ensure correct positioning, wiring, circuit protection and safe long-term operation.
