Description

Honeywell-Gent S4-770-S Optical Heat Multisensor and Sounder

System Overview

The S4-770-S is an Analogue Addressable Multisensor (Optical Smoke & Heat) with an integral sounder built into the unit.

A truly intelligent analogue sensor combining local processing in the sensor and the panel to achieve an immediate response to real fi res whilst minimising the risk of false alarms.

S-Quad leads the industry in fire sensing technology. A complete range of devices sensors with a unique combination of sensing elements to provide quick, intelligent fire decisions.

The innovative S-Quad multi-sensor is capable of detecting the products of combustion such as heat, smoke and carbon monoxide. Smoke detection is enhanced using patented dual optical scatter technology. This allows it to be configured to filter specific risks such as steam and dust, resulting in significantly reduced false alarms.

S-Quad’s inherent flexibility means it can be programmed to suit specific site applications. Different sensitivity states are set to incorporate combinations of optical, dual optical, heat and CO sensing elements. States can be selected depending on the different conditions in a room or a time period when interference may be more likely.

Key Features
