Photoelectric Smoke Detector - Wired

PA-1045H Wired Photoelectric Smoke Detector

The PA-1045H Photoelectric Smoke Detector is a reliable wired smoke detection device designed for early fire warning in residential, commercial, and light industrial environments. Using photoelectric sensing technology, it detects visible smoke particles produced by slow-smouldering fires, helping provide an important layer of protection for people, property, and equipment.

Designed for ceiling-mounted installation, the PA-1045H operates on 12V DC and is suitable for integration with compatible alarm panels and security systems. Its low standby current makes it efficient for continuous monitoring, while the relay output and LED alarm indication provide clear status feedback during an alarm event.

With a detection area of approximately 20m², the PA-1045H is ideal for rooms, offices, passages, storage areas, reception spaces, small shops, and other indoor areas where dependable smoke detection is required.
