Gent S4-34740 Beam Sensor Pair (Transmitter and Receiver)

Gent S4-34740 Beam Sensor Pair (Transmitter and Receiver) – Excluding Bracket and Base

The S4-34740 Beam Sensor Pair is a high-performance linear beam detection solution for large, open areas where standard point detection isn't practical or is too expensive. This system is perfect for high-ceiling environments like warehouses, atriums, and sports halls. Because it's powered and controlled directly through the loop, it eliminates the need for separate power supplies and helps keep installation costs low.

Featuring advanced one-person alignment and commissioning using integrated auto gain settings, the S4-34740 ensures precise setup with minimal labour. A built-in key-operated test facility allows for easy simulation of fire conditions from ground level, significantly improving maintenance efficiency and safety.

Certified to EN54 Parts 12 and 17, this beam detector integrates seamlessly with Gent Vigilon and Nano fire alarm control panels. Its intelligent software filters minimise false alarms while ensuring rapid fire detection. The unit’s dust-resistant optical lens design also reduces cleaning requirements, further lowering long-term maintenance costs.
