E2S Warning Signals has introduced the new H1 range of heat detectors.

Globally approved to UL, cUL, IECEx, and ATEX standards with explosion-proof, flameproof, increased safety, and intrinsically safe protection, the H1 range is available as part of the D1x and D2x families with marine grade, copper-free LM6 aluminum termination enclosures, in the STEx family with 316L stainless steel enclosures and the GNEx with GRP enclosures. 

UL521 and CAN/ULC-S530 approved

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).

heat detection in hazardous areas

The highly reliable and robust H1 range provides initial heat sensing in automatic fire and gas detection

The robust E2S termination enclosures are combined with heat detector elements as a completely approved assembly to create a fully certified solution for heat detection in hazardous areas.

Primarily used for signaling overheating or fire conditions, the highly reliable and robust H1 range provides initial heat sensing in automatic fire and gas detection and suppression systems.

D-A-F rate-compensated heat detector

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. 

availability and advantages

Selected variants can be specified with an LED to indicate an alarm condition and a wide range of addressable modules can be factory-installed.

Full details of the advantages of the E2S H1 rate-compensated detectors can be found on the E2S website and the advantages over traditional fixed or rate-of-rise detectors can be found in the associated Technical Bulletin.
