Hikvision DS-PDSMK-4BAR 4-Wire Photoelectric Smoke Detector with Built-In Sounder

Hikvision DS-PDSMK-4BAR 4-Wire Photoelectric Smoke Detector with Built-In Sounder

R299.00 Incl. VAT

The Hikvision DS-PDSMK-4BAR is a conventional 4-wire photoelectric smoke detector for wired alarm systems, combining smoke detection, an integrated audible alarm and relay output in a compact ceiling-mounted unit.

  • Photoelectric smoke detection: designed to detect smoke using a stable optical sensing chamber.
  • Built-in sounder: provides an audible alarm of at least 85 dB at 3 m.
  • Flexible alarm output: selectable normally open or normally closed relay output for connection to compatible wired alarm equipment.
  • 360° alarm indication: dual red LEDs make the alarm status visible around the detector.
  • Automatic reset: resets automatically after an alarm condition clears.
  • Requires wired power: operates from 10.2–13.8 V DC and requires connection to a suitable wired alarm system.

Description

Hikvision DS-PDSMK-4BAR wired smoke detection with built-in audible warning

The Hikvision DS-PDSMK-4BAR is a conventional, non-addressable photoelectric smoke detector designed for 4-wire alarm installations. It combines smoke sensing, a built-in sounder and a relay alarm output, making it suitable for adding smoke detection to compatible wired security and alarm systems.

Its low-profile ceiling-mounted housing uses dual red alarm LEDs for visibility around the detector, while the integrated sounder provides a local audible warning when smoke triggers an alarm.

Why Choose This Product?

  • Photoelectric detection: the optical smoke-sensing chamber provides a practical solution for detecting smoke without requiring adjustment or routine sensor replacement.
  • Built-in audible alarm: the integrated sounder produces at least 85 dB at 3 m, providing an immediate local warning at the detector.
  • Relay alarm output: the SPST relay can be configured as normally open or normally closed for integration with compatible wired alarm equipment.
  • Automatic reset: the DS-PDSMK-4BAR automatically resets after an alarm condition, with a specified reset period of approximately 28–35 seconds.
  • Easy-to-see alarm indication: two continuously illuminated red LEDs provide 360° visual indication when the detector is in alarm.
  • Compact ceiling installation: the detector measures just 100 mm in diameter and 35 mm high.

Before You Buy

The DS-PDSMK-4BAR is a wired, conventional smoke detector. It requires a 10.2–13.8 V DC power supply and appropriate wired alarm connections; it is not a battery-powered wireless detector.

Its alarm relay supports normally open or normally closed operation. Confirm that the alarm panel or other equipment being connected can accept the detector’s relay output and power requirements.
