Description

SECURICO SEC-PSD4 Photoelectric Smoke Detector provides early fire detection using optical sensing technology. Designed with a modern low-profile aesthetic, it seamlessly integrates into commercial and residential fire safety systems. Operating across a wide voltage range of 9 to 32VDC (nominal 12/24VDC), it delivers steady performance with minimal power draw.

Equipped with automatic drift compensation, the SEC-PSD4 maintains consistent sensitivity over time by adjusting for environmental dust accumulation. The unit incorporates dual bi-colour LEDs providing 360-degree status visibility, locking solid red during an alarm condition
