Key Features
- Addressable optical smoke detection
- Reliable response to smouldering fires
- Designed for Zeta MKII systems
- Low profile detector design
- Simple installation and maintenance
Overview
The Zeta MKII Addressable Optical Smoke Detector provides reliable smoke detection for use with Zeta MKII addressable fire alarm systems. It uses an optical sensing chamber to detect smoke particles produced by slow-burning or smouldering fires, making it suitable for many commercial and public environments.
The detector communicates directly with the fire alarm control panel through the addressable loop, allowing each device to be individually identified and monitored. This improves fault finding and enables faster response during alarm conditions.
Its low profile design allows discreet installation while maintaining effective detection performance. The detector is designed for straightforward installation, commissioning and maintenance within Zeta MKII fire detection systems.
