Overview

What it is and how it fits the system.

The Gent S4BK-711 is a Dual Angle Optical Heat Sensor in black from the S-Quad range, combining dual angle optical and heat detection in a single multi-sensor head. It operates on a 35V-48V loop across an ambient range of -10°C to 50°C and supports up to 200 devices per loop. The 117mm-diameter head weighs 110g, finished in black ABS HF380.

Technical overview

S4BK-711 is the Dual Angle Optical Heat Sensor (Black) from the Gent by Honeywell S-Quad range. It combines dual angle optical and heat detection in a single multi-sensor head, operating on a 35V-48V loop across an ambient temperature range of -10°C to 50°C and supporting up to 200 devices per loop. The 117mm-diameter head weighs 110g and is finished in black ABS HF380.

This sensor features an O2H symbol and is designed for use with S4-700 or S4BK-700 sensor bases in white or black, as well as IP21 sensor bases (S4-701, S4-705, S4BK-705) for enhanced ingress protection. It forms part of the Gent by Honeywell Vigilon S-Quad sensor range, offering backward compatibility through appropriate system upgrades. Physical wiring and terminal connections are detailed in the installation manual.
