Description
The Hikvision DS-PDSMK-4 is a conventional wired photoelectric smoke detector designed for early smoke detection in residential and commercial alarm applications.
It uses photoelectric smoke sensing technology and operates as a 4-wire, non-addressable detector. When smoke reaches the configured alarm threshold, the detector activates its alarm relay and provides a clear visual alarm indication through two red LEDs.
The detector operates from 10.2–13.8V DC, features low standby current, and provides an SPST relay output configurable as N/O or N/C, making it suitable for integration with compatible wired alarm control panels.
