Gamewell-FCI ATD-L3H High Temperature Heat Detector

The Gamewell-FCI ATD-L3H is an addressable high temperature heat detector designed for commercial and industrial fire alarm systems. It provides fixed temperature thermal detection at 190 degrees Fahrenheit 88 degrees Celsius, making it suitable for areas where higher normal ambient temperatures may make standard temperature heat detectors inappropriate.

Part of the Velociti Series 3 detector family, the ATD-L3H features addressable communication, rotary decimal addressing, dual LED status indicators, and a built in magnetic functional test switch. Its bright white, low profile housing provides a modern appearance for commercial life safety installations.

Product Functions

• Detects high temperature fire conditions
• Activates at 190 degrees Fahrenheit
• Reports alarm conditions to the fire alarm control panel
• Provides addressable point identification
• Continuously communicates detector status
• Provides visual status and alarm indication
• Supports rotary decimal addressing

Electrical & System Information

The ATD-L3H operates from a 15 to 32 VDC signaling line circuit and communicates using the Gamewell-FCI Velociti protocol. Rotary decimal switches provide addressing from 01 through 159, allowing each detector to be individually identified by the fire alarm control system.

Dual LEDs provide 360 degree status visibility. The indicators flash during normal communication and illuminate during alarm conditions according to system operation. A built in functional test switch can be activated with an external magnet to simplify routine detector testing and maintenance.
