Advanced Large-Area Fire Detection

The Honeywell Gent S4-34740 S-Quad Beam Detector Pair offers an industry-leading linear beam detection solution for open and high-ceiling spaces. Comprising a dedicated transmitter and receiver pair, it uses advanced infrared optical technology to continuously monitor for smoke across massive distances (up to 100 meters). This makes it highly economical, allowing a single pair to cover expansive areas that would otherwise require multiple traditional point smoke detectors.

Seamless Loop-Powered Integration

Engineered for effortless system integration, the S4-34740 is entirely loop-powered and addressable. It derives power directly from the Gent Vigilon fire alarm loop, eliminating the need for external power supplies, extra wiring, or complex interface modules. Up to 16 beam pairs can be wired onto a single loop, drastically reducing cabling overhead and installation labor costs.

Intelligent Operation & Fewer False Alarms

Utilizing sophisticated panel software filtering, this beam pair delivers an incredibly rapid response to real fire hazards while robustly rejecting ambient interference to minimize costly false alarms. The device features an automatic gain setting (Auto-Gain) for seamless, one-man alignment and commissioning, alongside a key-operated test feature to safely simulate beam obscuration during routine maintenance.

Key Features & Technical Benefits:

• Analogue Addressable Performance: Fully compatible with Gent Vigilon and Nano control panels.

• Cost-Effective Coverage: Monitors wide-open spaces up to 100m, replacing multiple individual smoke detectors.

• Loop-Powered Efficiency: No external Power Supply Unit (PSU) or extra power cables required.

• Built-in Line Isolators: Features two integral short-circuit isolators to protect loop integrity.

• Certified Standards: Fully approved and compliant with EN54 Parts 12 and 17 fire safety regulations.

• Smart Maintenance: Auto-gain alignment and key-switch remote test capability for fast commissioning.
