Hochiki SOC-E-IS Conventional Smoke Detector

The Hochiki SOC-E-IS is a high-performance conventional smoke detector designed for dependable fire detection in hazardous and general-use environments. Featuring a removable sensing chamber and advanced drift compensation technology, it ensures long-term stability and reduced maintenance requirements. With Automatic Sensitivity Window Verification (ASWV), the detector continuously self-monitors and adjusts its sensitivity to compensate for dust build-up, helping maintain accurate detection over time. Certified for use in explosive atmospheres (ATEX), the SOC-E-IS is suitable for Category 1 hazardous areas while still being ideal for a wide range of commercial and industrial settings.

Product Features

Removable High-Performance Chamber The detector features a high-efficiency sensing chamber that is fully removable, simplifying maintenance and cleaning without compromising sensor performance. Automatic Sensitivity Window Verification (ASWV) Incorporates advanced drift compensation technology that automatically adjusts detector sensitivity, maintaining reliable performance and reducing false alarms due to contamination or environmental changes. Remote Indicator Output Supports a remote LED indicator connection for clear alarm visibility in concealed or high-mounted installations. Certified for Hazardous Areas ATEX classified as Ex ia IIC T5 Ga, allowing safe installation in Category 1 hazardous areas (and all lower categories), where explosive atmospheres may be present. Wide Operating Voltage Range Operates between 12V and 30V DC (supports up to 30V), providing flexible compatibility with a wide variety of fire alarm panels. Low Profile, Compact Design The detector’s sleek, low-profile design with a single-piece outer casing enhances aesthetics and makes it easy to install in space-constrained environments. 360-Degree Alarm Indication Equipped with a single red LED visible from all angles for quick alarm identification from any direction. Third-Party Approvals Approved by leading certification bodies including LPCB and VdS, ensuring high safety and quality standards are met.
