Analogue Multi-Sensor HOCHIKI ACA-E

Hochiki’s Multi-Sensor is a combined Photoelectric Smoke sensor which has an unique ‘Flat Response’ chamber design and a highly linear Thermal sensor within the same housing. This enables the sensor to be equally sensitive to a wider range of combustible materials, thus removing the need of ionisation detectors in the majority of applications. The sensor can communicate the condition of sensing elements using the Hochiki ESP Enhanced System Protocol.
• Different modes allow different sensing elements to be selected
• Compatible with existing ESP bases
• Twin alarm LEDs on the head for 360° viewing
• Remote Indicator output as standard
• Polling LEDs controlled from control panel (Flashing or Non-Flashing
