While both are multi-sensors, the S4-710 is a standard Optical-Heat detector. The S4-711 uses Dual-Angle Optical Scatter technology. This means the S4-711 is much better at distinguishing between real smoke and "nuisance" sources like steam or dust, making it the superior choice for hotel corridors or near bathrooms.

No, the S4-711 is the detector head only. To install it, you will need the S4-700 Common Base. This modular design allows you to swap heads for maintenance without rewiring the base.

The S4-711 has a Device Load Factor of 1. This is the lowest possible rating for an S-Quad sensor, allowing you to populate a full loop of up to 200 devices (subject to total loop current limits).

The S4-711 is designed for the Gent Vigilon and Vigilon Compact/Compact Plus addressable systems. It is a closed-protocol device and is not compatible with standard conventional fire panels or other addressable brands.

• 
  
  Flashing Green: Device is operating normally and communicating with the control panel.
• Flashing Red: Indicates the detector is in alarm condition (fire detected).
• Flashing Amber/Yellow: Fault condition, such as contamination, sensor failure, or communication error.
• Steady Red: Detector is latched in alarm (may require reset from the panel).
• No LED: Device is not powered or not communicating with the loop.

These LED patterns help engineers and maintenance staff quickly identify the status of the detector during routine checks or fault-finding. For site-specific programming, the flash rates or colors may be customized, but the above are the standard factory defaults for the S-Quad range

• The Gent S4-711 is part of the S-Quad range, which uses a different protocol and base compared to the older Gent 34000 series detectors.
• Direct replacement (i.e., simply swapping the detector heads) is not possible. The S4-711 requires the S-Quad (S4-700 series) base, and the wiring may need to be adapted.
• The control panel must support the S-Quad protocol. Most 34000 series systems are legacy and may not be compatible with S-Quad devices without a panel upgrade or interface module.
• If you are upgrading a system from 34000 series to S-Quad (including S4-711), you will need to:
  
  Replace the detector bases with S-Quad bases.Re-address the new detectors as per the S-Quad system requirements. Confirm that the fire alarm control panel is compatible with S-Quad devices, or plan for a panel upgrade.
