Description
The Apollo 55000-217APO is a conventional ion smoke detector designed to provide dependable fire detection in commercial fire alarm systems. It utilizes a low activity radioactive foil to ionize the air within the sensing chamber, enabling rapid detection of fast flaming fires that produce relatively small amounts of visible smoke.
Part of the Apollo Series 65 range, the detector features low current consumption, a wide operating voltage range, and a highly visible alarm LED. Its plug in design allows quick installation and maintenance, making it suitable for a variety of commercial and industrial fire detection applications.
Product Functions
- Detects smoke using ionisation sensing technology
- Reports alarm conditions to the fire alarm control panel
- Provides visual alarm indication
- Supports remote LED indication
- Continuously monitors smoke conditions
- Operates on conventional two wire initiating circuits
