Product details
The Hochiki SOC-E3N(BLK) is the black version of Hochiki's CDX conventional optical smoke detector, made for dark ceilings and interiors where a white or ivory head would stand out. It is LPCB approved to EN 54-7 and runs on 12-30 V DC. For white, ivory, addressable ESP and multi-sensor models, see all Hochiki smoke detectors.
The Hochiki SOC-E3N(BLK) is a conventional photoelectric (optical) smoke detector from the Hochiki CDX range, supplied in a black 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.

Hochiki smoke detector FAQs
Is the SOC-E3N(BLK) an addressable or conventional Hochiki smoke detector?
It is conventional. It belongs to the Hochiki CDX range and is compatible with the majority of existing conventional fire alarm systems. If you need an addressable black-case detector, the Hochiki ESP ALN-EN(BLK) is the ESP equivalent.
Which base does it fit?
The detector head is supplied without a base. Compatible bases are the YBN-R/6, YBN-R/6SK, YBO-R/6R, YBO-R/6RS, YBO-R/6RN and YBO-R/6PA, with base fixing centres of 48-74 mm.
Can the smoke chamber be cleaned or replaced?
Yes. The High Performance smoke chamber is removable for cleaning or replacement (replacement chamber SLV/ALK), and the red LED flashes once every three seconds if the contamination limit is exceeded.
