Hochiki ESP Addressable Weatherproof Heat Detector
£54.61 (inc VAT: £65.53)
Summary
The Hochiki ACB-EW is a waterproof multi-heat sensor designed for harsh and external environments where reliable fire detection is critical. With its IP67 rating, this sensor provides complete protection against dust and water ingress, making it ideal for outdoor applications, car parks, warehouses, and industrial environments.
Fully compatible with Hochiki’s ESP analogue addressable protocol, the ACB-EW offers sophisticated fire detection through its dual thermal sensing technology. The sensor incorporates both a variable fixed temperature heat element and a rate of rise heat element, which can be controlled independently or simultaneously from the control panel. This flexibility allows the system to be optimised for different environmental conditions and application requirements.
The ACB-EW features twin fire LEDs providing 360° visibility for easy status identification from any angle. The sensor is supplied complete with its own fixing base and connects to the loop system via flying leads and waterproof connectors, ensuring reliable performance in demanding conditions. With LPCB and VdS approval to Classes A, B and C, the ACB-EW meets the highest industry standards for fire detection.
Please note: You will need a Hochiki PL-2 Programming Lead to address this detector.

FAQ
What is the IP rating of the Hochiki ACB-EW?
The ACB-EW is rated to IP67, providing complete protection against dust ingress and temporary immersion in water. This makes it suitable for external use and harsh environments.
Can the ACB-EW be used outdoors?
Yes, the ACB-EW is specifically designed for external use. Its IP67 rating and operating temperature range of -10°C to +50°C make it ideal for outdoor applications, car parks, and industrial environments.
What types of heat detection does this sensor use?
The ACB-EW incorporates two thermal elements: a variable fixed temperature heat element and a rate of rise heat element. Both can be controlled from the control panel, allowing either element or both to be active simultaneously.
Is a special base required for installation?
The ACB-EW is supplied with its own dedicated fixing base. The sensor cannot be used with standard detector bases and must be installed using the supplied base with fixing centres of 48-74mm.
How does the sensor connect to the fire alarm loop?
The ACB-EW uses flying leads that connect directly to the loop circuit via waterproof connectors, ensuring reliable connections in wet or damp environments.
What protocol does the ACB-EW use?
The sensor is fully compatible with Hochiki’s ESP (Enhanced Systems Protocol) analogue addressable protocol, providing digital communications with the control panel.
Do I need any special equipment to programme this detector?
Yes, you will need a Hochiki PL-2 Programming Lead to address this detector.
Can the LED indicators be controlled?
Yes, the sensor’s twin LEDs can be set to either pulsing or non-pulsing mode via the control panel, subject to panel compatibility.
