General

he TC806B1076, TC806B1084 Photoelectric Smoke Sensors and TC807B1059 Ionization Smoke Sensor are intelligent detection devices that provide 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.

The TC806B Photoelectric Smoke Sensor has an optical sensing chamber and uses the light-scattering principle. The TC806B with Thermal Smoke Sensor also includes a dual 135°F (57°C) fixed temperature thermal sensing element. The TC807B uses a dual, unipolar ionization chamber. These sensors provide stability and fast response to a broad range of fire conditions. The address for each sensor is set via two direct-dial decade switches. Dual LEDs on the sensors provide 360-degree visual indication. A common mounting base accommodates the TC806B or TC807B. A total of 99 addresses in the Conventional Loop Interface Protocol (CLIP) mode are supported. Control panels that support FlashScan can use up to 159 detectors on a loop.

Specifications

• Make: Honeywell
• Model: TC806B1076
• Electrical Ratings: Voltage Range: 15 Vdc to 32 Vdc, peak.
• Standby Current: 300 µA at 24 Vdc (one communication every 5 seconds with LED blink enabled). LED Current: 6.5 mA at 24 Vdc.
