E2S Warning Signals H1 range of heat detectors

The E2S Warning Signals H1 range of heat detectors are designed for hazardous areas. They are globally approved to UL, cUL, IECEx and ATEX standards and offer explosion-proof, flameproof, increased safety and intrinsically safe protection.

The H1 range contains Ex db flameproof, Ex db eb increased safety and Ex ia intrinsically safe variants approved for use in Zone 0, 1, 2, 21, 22 and Class I/II Division 1 and Division 2. They are UL521 and CAN/ULC-S530 approved and SIL2 compliant to IEC61508 (2010).

The E2S termination enclosures are combined with heat detector elements as a complete approved assembly to create a fully certified solution for heat detection in hazardous areas. Primarily used for signalling overheat or fire conditions, the H1 range provides the initial heat sensing in automatic fire and gas detection and suppression systems.

Incorporating industry standard Detect-A-Fire (D-A-F) rate compensated heat detector elements that feature stainless steel housings and hermetically sealed contacts the H1 range is available in a wide range of operating temperatures. All versions feature IP66/67, Type 4/4X/13/3R sealing for the harshest of environments and an optional protective guard for the element. Selected variants can be specified with an LED to indicate an alarm condition and a wide range of addressable modules can be factory installed.
