      Smoke Detector

        D-A411 Intelligent Photoelectric Smoke Detector is an addressable fire alarm device cooperating with SHIELD intelligent fire alarm control panels to build a fire detection system. It shows fire alarm by LED indicators and transmits the fire signal to the control panel.

        • Twin LED for 360° view.
        • Electronically addressed in field.
        • Built-in microprocessor stores 14 history data.
        • Drift compensation to suit environment changing extensively.
        • Self-diagnostic.
        • Remote indicator output available.
        • Complies with EN 54-7 standard.
