Description
The Honeywell TC808B1058 Intelligent Thermal Detector is an addressable heat detector designed for property protection in fire alarm systems. The detector uses a thermistor-based sensing circuit that provides both fixed temperature detection and rate-of-rise heat detection, allowing the system to respond quickly to rapidly developing fires.
This detector communicates directly with compatible Honeywell fire alarm control panels using FlashScan or CLIP communication protocols over a two-wire signaling line circuit (SLC). The address of each detector is set using onboard decade address switches, enabling precise device identification and location reporting within the fire alarm system.
The TC808B1058 provides rate-of-rise detection at 15°F (8.3°C) per minute, with a fixed alarm temperature of 135°F (57°C). Dual bi-color LEDs provide 360-degree visibility and indicate device status, blinking green during normal communication and lighting steady red during alarm conditions.
Designed as a plug-in detector head, the TC808B1058 installs onto compatible mounting bases, allowing easy maintenance and replacement without rewiring. Optional bases provide additional functionality such as sounder, relay, or isolator capabilities depending on system requirements.
