Faraday 8810 Addressable Photoelectric Detector

Faraday 8810 and 8811 are plug-in, two-wire photoelectric detectors, compatible with Faraday’s MPC-Plus systems. Each detector consists of a dust resistant, field serviceable photo chamber, microprocessor based electronic circuitry with plastic cover and base. Electronic component packaging uses surface mount type technology. The entire electronic assembly is fully protect it from noise transients by shielding and is coat it to resist moisture and corrosion.

Faraday 8810 and 8811 photoelectric detector utilizes a light emitting diode (LED). Also light sensing photodiode assembled in a fixed array so that under normal conditions. Light transmitted by the LED is direct it away from the photodiode. Also scatter it throughout the smoke chamber in a controlled pattern. The smoke chamber is design it to manage light dissipation and also extraneous reflections from dust particles. Or other nonsmoke airborne contaminants in such a way as to maintain stable, consistent detector operation. The 8810 and 8811 detector’s microprocessor uses an integral EEPROM to store the detector’s address, and other critical operating parameters which include an assigned, programmable value for alarm and trouble thresholds.

The microprocessor’s software employs sophisticated, proprietary algorithms to identify and disregard false alarms caused by radio frequency (RFI) and electromagnetic (EMI) interference and also validates all trouble conditions before annunciating or reporting to the control panel. Communications within the detector itself and also between the 8810 and 8811 detectors and the control panel or the 8820 programming accessory are supervised and safeguarded against disruption by reliable, microprocessor based error checking routines. Additionally, the microprocessor supervises all EEPROM memory locations and provides a high degree of EEPROM failure fault tolerance.
