Overview
What it is and how it fits the system.
The Gent S4-711 is a dual optical heat sensor, a Vigilon loop-powered fire detection device from the S-Quad range. It carries a device load factor of 0.5, with up to 200 supported per loop.
Technical overview
The Gent by Honeywell S4-711 is a Dual Optical Heat Sensor from the S4 Detectors range, specifically a Vigilon loop-powered fire detection device. It is defined by its dual optical heat sensing capability and loop-powered operation within the S-Quad family of detectors.
This SKU supports a maximum of 200 units per loop, with each device contributing a load factor of 0.5 units, enabling efficient system design for larger installations. It requires the common S4-700 white sensor base for mounting and is compatible with optional accessories including the S4-FLUSH semi-flush mounting kit and the 805580 removal tool kit. Unlike its siblings S4-770-S and S4-771-S, the S4-711 uniquely combines optical and heat detection in a single loop-powered unit without specifying separate sensitivity classes or temperature ratings in this data slice.
