Hochiki ACC-EN(SCI) Addressable Optical/Heat Multi-Sensor Detector with SCI - Ivory Case

The Hochiki ACC-EN(SCI) is an intelligent optical/heat multi-sensor with a built-in short-circuit isolator (SCI), in an ivory case, for the Hochiki ESP analogue addressable fire detection system. It combines a thermal element with a High Performance photoelectric smoke chamber and has three modes controlled from the fire alarm control panel: optical, heat or both.

Key features

• Integral short-circuit isolator
• Three user-selectable modes: optical, heat or combined
• Removable High Performance smoke chamber for easy maintenance
• Twin LEDs give 360° viewing
• Polling LEDs can be set to pulsing or non-pulsing from the panel (control panel compatibility required)
• Variable sensitivity
• Electronically addressed with the Hochiki TCH-B200 hand-held programmer
• LPCB and VdS approved to classes A1 and C
