Unit I GENERAL INFORMATION DESCRIPTION The UVC120 Flame Detectors combined with the U1F, U2F or U4F-UV Fire Controller provide fast, reliable flame detection in a wide variety of applications. The microprocessor based controllers simultaneously monitor up to four ultraviolet (UV) detectors to provide maximum operating flexibility at minimum expense. The Automatic Visual Integrity (vi) feature provides a continuous check of optical surfaces, sensitivity and electronic circuitry of the detector/

BASIC OPERATION - CONTROLLER CONTROLLER FACEPLATE DESCRIPTION The controller faceplate provides LEDs and two digital displays for identifying status conditions, a bar graph display for indicating an alarm condition and MENU/SET and SELECT/RESET push- button switches (See appendix for instructions on activation) for testing and resetting the system. Refer to Figure 3. Figure 3 - Controller Face-Plate < Digital Displays - The left side of the digital display is normally off. If a fire alarm or vi

OUTPUTS Relay Outputs: The Instant, Area and Fault relays have SPDT contacts rated 5 Amps at 30 Volts DC or 250 Volts AC. The Instant and Area alarm relays are programmable for either normally energized or normally de-energized operation and for latching or non-latching (programmable as a group not individually). The fault relay is only normally energized. The relays can be configured with jumpers for normally open or normally closed contacts. RECOMMENDATION The fault relay output should not b

The UV sensor responds to radiation other than ultraviolet. X-rays can activate the detector and are often used in industrial inspection. It may be necessary to disable the system if X-ray inspection is conducted nearby. UV radiation other than that produced by an actual fire is referred to as “background UV.” An example of a high level of background UV could be the case of a flare stack situated outside of a building. The UV radiation produced by this flare may be detected when a door to the

sensitivity levels by programming the controller to respond at a pre-determined detector count rate which is dependent upon the intensity of the ultraviolet radiation reaching the detector, which in turn depends on the type of fuel, temperature, flame size, distance from the detector and concentration of UV absorbing vapors present. Programming the controller to respond to a low count rate results in high system sensitivity. Unit III SYSTEM INSTALLATION INSTALLATION GENERAL WIRING REQUIREMENTS N
