Satel MSD-350 Wireless smoke detector

Satel MSD-350 Wireless smoke detector

The MSD-350 detector can detect the early stages of fire development when there is some visible smoke. It can operate as a stand-alone device or as part of the wireless system.

Features:

• EN 14604 compliant visible smoke sensor
• Detection of optical chamber fouling
• Red LED for optical signaling
• Built-in sounder
• Test feature
• Tamper protection against enclosure opening (when working in a wireless system)
• Battery status control

Smoke detection
An optical method is used for the detection of visible smoke. The detector automatically compensates for gradual changes in the optical chamber caused by deposition of dust. When the concentration of smoke in the optical chamber exceeds a given threshold, an alarm is triggered.

Fire alarm signaling
The alarm is indicated visually (LED steady light) and acoustically (intermittent sound) for 5 minutes. Pressing the test/reset button (designated with the letter A in Figure 2) during the alarm will clear the alarm condition and will block the smoke detection function in the detector for 5 minutes.

The detector is supported by:

• PERFECTA 16-WRL, PERFECTA 32-WRL and PERFECTA-T 32-WRL control panels
• MICRA alarm module (firmware version 2.02 or newer)
• VERSA-MCU controller
• MTX-300 controller

It can operate as a stand-alone device or as part of the wireless system.
