Twinflex ASD Smoke and Heat Sensor Complete With Base & Sounder

The Twinflex ASD Smoke and Heat Sensor is an advanced addressable detector designed to deliver high-performance fire detection with the convenience of an integrated sounder and base. Combining a photoelectric smoke sensor and a thermistor heat sensor, the unit can be configured to detect smoke, heat, or both—making it ideal for a wide variety of environments. With seven programmable sounder tones and adjustable volume levels (65dB(A), 80dB(A), or 85dB(A)), this device also eliminates the need for separate sounders, reducing installation time and system complexity.

Built-in short circuit isolators protect the loop in the event of a fault, while intelligent communication allows direct interaction with Fike SITA200plus, Duonet, and Quadnet panels for faster, more reliable response. The unit self-calibrates every six hours to maintain optimal sensitivity, and a clear LED status indicator provides real-time visibility of the device condition.
