Hikvision 4-Wire Photoelectric Smoke Detector DS-PDSMK-4BAR

The Hikvision DS-PDSMK-4BAR is a wired 4-wire photoelectric smoke detector designed for early fire detection in residential, commercial, and industrial environments. It uses a stable photoelectric sensing chamber to detect smoke particles in the air, providing reliable and fast response to potential fire hazards.

The detector features advanced algorithms for improved detection discrimination, helping to reduce false alarms caused by dust or environmental interference. It supports 4-wire connection with 12V DC power supply and includes a relay output (NO/NC) for integration with fire alarm panels or intrusion alarm systems.

The device is designed with a low-profile housing and SMD circuit board for improved durability and compact installation. Dual LEDs provide 360° visibility for status indication. It may also support optional features depending on configuration, such as auto-reset functionality and internal sounder (built-in buzzer).

This model is ceiling-mounted and suitable for continuous monitoring in indoor environments such as offices, warehouses, residential buildings, and technical rooms.
