Emerson 8102-HO-IP Hazardous Area IS+FM Approved Siren/Horn

Description

Emerson 8102-HO-IP Hazardous Area IS+FM Approved Siren/Horn

Overview

The Emerson 8102-HO-IP is a robust, high-output audible signaling device engineered for critical alarm and notification applications in hazardous and industrial environments. This siren/horn combines a powerful acoustic output with an integrated, certified flame path (IS+FM) assembly, allowing it to be installed directly in classified hazardous areas without the need for an external explosion-proof enclosure. It is designed to provide unmistakable auditory warnings for gas detection, fire alarm, process shutdown, and other safety-critical systems in the oil & gas, chemical, petrochemical, and energy industries.

Key Features & Benefits

• Intrinsically Safe & Explosion-Proof Design: The unique integrated IS+FM flame arrestor design provides dual protection: it prevents the device from being an ignition source (intrinsic safety) and contains any potential internal explosion. This allows for installation in Class I, Division 1 and 2 hazardous locations.

• High Acoustic Output: Engineered to produce a loud, penetrating sound output (e.g., up to 115 dBA or higher) that can cut through high levels of ambient industrial noise to ensure alarms are heard clearly.

• Rugged & Corrosion-Resistant Construction: Typically constructed from high-integrity materials like copper-free aluminum with a durable polyurethane coating or stainless steel, offering excellent resistance to corrosion, moisture, and environmental degradation.

• Ingress Protection: Features a high IP rating (e.g., IP66 or IP67), making it dust-tight and protected against powerful water jets, ensuring reliable operation in harsh outdoor and wash-down environments.

• Versatile Voltage Options: Available in a range of standard voltage ratings (e.g., 24 Vdc, 24 Vac, 120 Vac, 230 Vac) to suit various control system requirements.

• Multiple Sound Patterns: Often capable of supporting multiple sound patterns (steady, wail, pulse) selectable via wiring or internal switches, allowing for differentiated alarms for different emergency scenarios.
