Hochiki CDX Conventional Optical Smoke Detector (Ivory Case) (SOC-E3N)

The Hochiki SOC-E3N is a conventional photoelectric (optical) smoke detector from the Hochiki CDX range, supplied in an ivory case. It is compatible with the majority of existing conventional fire alarm systems. Hochiki's High Performance photoelectric chamber removes the need for ionisation detectors in most applications, and ASWV drift compensation keeps the detector at its optimum sensitivity to help reduce false alarms.
