Gent S4-710 S-Quad Optical Heat Sensor

The S4-710 is an optical heat sensor from Gent by Honeywell, designated symbol OH and part of the S-Quad/Vigilon sensor range. It integrates both optical and heat detection within a single addressable unit, supporting up to 200 devices per loop for scalable fire system deployment.

Weighing 110g (170g with base) and measuring 117mm in diameter by 49.6mm in height, the S4-710 is designed for compatibility with the common white S-Quad sensor base (S4-700). Optional accessories include the semi-flush mounting kit (S4-FLUSH) and removal tool kit (805580) for varied installation and maintenance needs.

This device forms part of the broader S4 Detectors range, specifically configured as a detector-only unit within the Gent by Honeywell portfolio. Its dual-sensing capability enhances responsiveness to developing fire conditions by combining smoke and temperature monitoring in one addressable point. The sensor is engineered for reliable integration into addressable fire alarm systems, where loop capacity and device interoperability are critical for system design and expansion. Installation requires the common S4-700 base, with optional kits available to accommodate semi-flush mounting or simplified removal during servicing, helping to ensure adaptability across diverse application environments.
