Hikvision DS-PDSMK-4BAR 4-Wired Non-addressable Smoke Detector

Hikvision DS-PDSMK-4BAR 4-Wired Non-addressable Smoke Detector The Hikvision DS-PDSMK-4BAR is a four-wire photoelectric smoke detector designed for ceiling-mounted fire detection applications. Its stable smoke-sensing chamber, advanced detection algorithms and resistance to unwanted alarms help provide dependable detection without requiring routine chamber adjustment or replacement. Dual red LED indicators offer clear 360-degree alarm visibility, while the built-in sounder produces an audible output of at least 85 dB at 3 metres. Its low-profile housing provides a neat, unobtrusive finish when installed on a ceiling. Reliable Photoelectric Smoke Detection The detector uses a stable photoelectric smoke-sensing chamber together with advanced algorithms to distinguish smoke conditions more effectively. Its alarm threshold is rated at 0.10 to 0.16 dB/m, equivalent to 1.51% to 2.73% per foot obscuration. Clear Visual and Audible Indication Two continuously emitting red LEDs provide 360-degree visibility, making detector status easier to identify from different positions in the room. An internal sounder delivers an output of at least 85 dB at a distance of 3 metres. Practical Four-Wire Integration The DS-PDSMK-4BAR operates from a 10.2 V to 13.8 V DC power supply. Its four-wire configuration includes N/C or N/O alarm relay output support and an automatic reset function for integration with compatible wired alarm systems.
