Two-phase occupancy sensor

Electrical Review Logo

Automated lighting control specialist BEG has launched an innovative new occupancy sensor that can keep buildings using two power supply circuits illuminated even when one fails.

Designed to control two separate lighting loads from a single unit, the PD4-M-2C-DS-FC is the German manufacturer’s latest energy-saving product to be released from its popular Luxomat range.


The new two-phase occupancy sensor is ideal for hospitals and data centres as it can be connected to two different AC circuits. Health care institutions and server rooms typically use separate channels to protect their power supplies, such as an emergency back-up generator in addition to the main power supply, so escape routes are illuminated in the event of a power outage.

The Luxomat enables the illumination system to be divided into two electronically isolated and distinct groups which reduces the risk of total light failure.
