Faraday 8811 Photo/Thermal Detector P/N: 500-095112FA

In general, the Faraday 8810 and Faraday 8811 are plug-ins, two-wire photoelectric detectors, compatible with Faraday’s MPC-Plus systems. Also, each detector consists of a dust-resistant, field serviceable photo chamber, microprocessor-based electronic circuitry with a plastic cover and base. Electronic component packaging uses surface-mount technology. Besides, the entire electronic assembly is fully protected from noise transients by shielding and is coated to resist moisture and corrosion.

The 8810 and Faraday 8811 photoelectric detector utilizes a light-emitting diode (LED) and a light-sensing photodiode assembled in a fixed array so that under normal conditions, light transmitted by the LED is directed away from the photodiode and scattered throughout the smoke chamber in a controlled pattern. Furthermore, the smoke chamber is designed to manage light dissipation and extraneous reflections from dust particles or other nonsmoker airborne contaminants in such a way as to maintain stable, consistent detector operation.

The 8810 and 8811 detectors’ microprocessor uses an integral EEPROM to store the detector’s address, as well as other critical operating parameters, which include an assigned, programmable value for alarm and trouble thresholds.
