The TC806B1076 Photoelectric Smoke Sensor is an intelligent detection device which provides two-way communication with the Honeywell fire alarm systems. The fire alarm panel loop controller uses a proprietary communication protocol containing both digital and analog signals that allow each sensor to communicate its individual address, sensor type (such as photoelectric or ionization) and an analog value. The panel analyzes the analog signal to measure the sensitivity of each sensor and to determine its status: alarm, prealarm, normal and trouble.
