Unit I GENERAL INFORMATION

DESCRIPTION

The UVC120 Flam e Detectors combined with the U1F, U2F or U4F-UVFire Controller provide fast, reliable flam e detection in a wide variety of applications. The microprocessor based controllers sim ultaneously monitor up to four ultraviolet (UV) detectors to provide maxim um operating flexibility at minim um expense. The Autom atic Visual Integrity (vi) feature provides a continuous check of optical surfaces, sensitivity and electronic circuitry of the detector/controller system . Autom atic fault identification monitors system operation and provides a digital display of system status using a numerical code. Controller response includes actuation of relays for direct control of field response devices and a full array of faceplate indicators. Other features include individual channel and area identification, "voting" capability and manual vi testing.

<System Sensitivity:

Sensitivity for the standard controller is field adjustable over a range of 8 through 120 counts per second (cps) in increm ents of 8 cps. The maxim um response distance is achieved at an 8 cps sensitivity setting. For applications involving high background radiation potential, the system can be de-sensitizedby increasing the count rate required to actuate alarm s. The 120 cps setting is the lowest sensitivity.

<Response Time:

Response to a saturating (high intensity) UV source is typically 10 m illiseconds for the instant alarm outputs and 0.5 seconds for the area alarm outputs when sensitivity is set for 8 cps and tim e delay is set for 0.5 seconds (m inim um settings).

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 andSELECT/RESET pushbutton 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 visual integrity fault is detected, it indicates the channel number of the alarm or fault. The digital displays indicate system status including system error codes, visual integrity (vi) faults, system faults or fire alarms. The right side of the display shows ‘nor’ in normal operating mode. If more than one channel is in an alarm or fault condition the digital displays will cycle through these channels. Since at least one side of the display is always lit they also function as a power indicator.

<Bar Graph Display - Normally off. Flashing when fire detected in any area.

<Instant LED - (no time delay) Flashes when any detector signal exceeds the fire sensitivity setting.

<Area 1 & 2 LEDs - (Area 1 only for U1F) If the selected “voting” criteria of the area and the preset time delay has elapsed the corresponding LED starts flashing.

<Fault LED - flashes upon detection of an overall system fault orvi fault.

<Channel LEDs - (1, 2 or 4 depending on model) flash to indicate detector in alarm and remain illuminated until reset after an alarm condition has returned to normal.

<MENU/SET Reed Switch - is used to enter the main menu, to toggle through menu selections and in conjunction with theSELECT/RESET Reed Switch to enter the special functions menu.

<SELECT/RESET Reed Switch - is used for a basic system reset, menu selection and with theMENU/SET Reed Switch to enter the special functions menu. This switch is also used during the manualvi test.
