Overview of Hikvision DS-PDSMK-4BAR

The Hikvision DS-PDSMK-4BAR is a 4-wire photoelectric smoke detector designed for connection to intrusion and alarm panels on a 12 VDC supply. A stable photoelectric sensing chamber needs no adjustment or replacement, while advanced algorithms improve detection discrimination and reduce unwanted alarms. It provides a relay alarm output, an internal sounder rated at 85 dB or more at 3 m, and dual red LEDs visible through 360°. The slim ceiling-mounted housing suits villas, apartments, offices, hotel rooms, shops and storerooms where early smoke warning is required.
