Description
The Honeywell TC807B1059 is an ionization smoke detector head designed for use with the S911 UL mounting base in intelligent fire alarm systems. It provides early detection of fast-flaming fires by sensing combustion particles in the air through a dual ionization chamber. The device is intended for commercial fire protection systems requiring addressable smoke detection and reliable system integration.

Information About TC807B1059
The TC807B1059 is part of Honeywell’s intelligent sensor series used in addressable fire alarm loops with compatible control panels. It operates using a dual ionization sensing chamber that detects changes in ionization current caused by smoke particles entering the chamber. The detector communicates with the fire alarm panel using a proprietary loop protocol, allowing each sensor to transmit its address, status, and analog detection values. It is designed for plug-in installation into a common base (S911 UL base), making maintenance and replacement straightforward in commercial fire alarm systems.
Key Features:
- Ionization Detection: Uses dual ionization chambers for fast-response fire detection.
- Addressable Operation: Communicates individually with fire alarm control panels via loop protocol.
- Plug-in Design: Installs easily into S911 UL compatible mounting base.
- Dual LED Indicators: Provides 360° visual status indication for alarm and normal conditions.
- Intelligent Sensing: Continuously monitors sensitivity and device condition.
- Stable Performance: Designed for consistent detection in varying environmental conditions.
- Low Profile Design: Compact sensor head for standard ceiling installations.
The TC807B1059 delivers the reliability and precision required for intelligent addressable fire detection systems in commercial environments.
