Description
The Hikvision DS-PDSMK-4BAR is a conventional wired photoelectric smoke detector designed for early smoke detection and audible alarm notification in residential and commercial applications.
It uses an advanced photoelectric smoke sensing chamber to provide reliable smoke detection with high immunity against unwanted alarms. The detector operates on a 4-wire, 12V DC system and includes an alarm relay output configurable as Normally Open (N/O) or Normally Closed (N/C).
Unlike the standard DS-PDSMK-4, the DS-PDSMK-4BAR includes a built-in sounder rated at ≥85 dB at 3 meters and supports an automatic reset function with a reset time of 28–35 seconds. Dual red LEDs provide 360° visual alarm indication.

Why Choose Hikvision DS-PDSMK-4BAR?
The DS-PDSMK-4BAR combines smoke detection, audible warning and visual indication in one device. Its integrated ≥85 dB sounder means the detector can provide an immediate local audible warning when smoke is detected.
Compared with the DS-PDSMK-4, this BAR version adds both the built-in sounder and automatic reset function, making it the more feature-rich option when local audible notification is required.
