Series 65 Base Mounted UV Flame Detector

Product code: 55000-025APO

55000-025APO - Series 65 Base Mounted UV Flame Detector
The Conventional Base Mounted UV Flame Detector is designed to protect enclosed indoor areas where open flaming fires may be expected. The detector has a fast-acting response to flames up to 25m away and is equipped with a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation.

Brand Information

Series 65 incorporates well-proven sensing technologies, including an Integrated Circuit based on that used in XP95 analogue addressable detectors. The Series 65 range has a wide operating voltage of 9–33V and consists of ionisation, integrating ionisation and optical smoke detectors, four grades of heat detector and a range of bases.

Brand Features

Wide-operating voltage of 9–33 V DC Wide-operating and storage temperature of -20°C to +60°C Can be used on security systems Electrically and mechanically compatible with Series 60 Proven detection performance

Electrical Description

The detector signals an alarm state by switching an alarm latch on, increasing the current drawn from the supply from 550μA to a maximum of about 75mA. This fall in the impedance of the detector is recognized by the control panel as an alarm signal. The alarm current also illuminates the detector’s integral LEDs. A remote indicator connected between the L1 IN terminal and the –R terminal will have a voltage equal to the supply voltage less 1V across it and so will illuminate. To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 33V DC and a minimum of 12V DC in normal operation. The supply may fall to 6V DC in alarm conditions if a supply current of at least 10mA is available at this voltage. To ensure effective illumination of the integral LEDs and any remote indicator, the supply to the detector should exceed 12V. To restore the detector to quiescent condition, ensuring all flames are extinguished, interrupt the electrical supply to the detector for a minimum of one second. Note: When using the detector the following must be avoided; outside viewing, UV lamps, electrical sparking, welding and sources of radiation, UV light sources, prolonged ambient temperatures above 60°C and obstructions to the field of view.

Operation

The detector is sensitive to ultraviolet radiation emitted by flames during combustion. Since it requires only UV radiation the Flame Detector responds even to stationary flames with no flicker like cigarette lighters and blue gas flames. The detector is set to respond to ultraviolet radiation (185 to 260nm) emitted by almost all flames, including those invisible to the naked eye, e.g. hydrogen fires. The detector has a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation and is designed for internal fully enclosed areas. Caution: The detector will also detect electrical discharges from lightning or arc welding.

Application

UV flame detectors are designed for use in enclosed spaces and require a clear line of sight within the area to be protected. They are unaffected by draughts or convection currents. They are fast reacting and respond to a flame more than 25m away.

Additional Information

Installation note: If fitting to an XP95 Zone Monitor do not fit more than one device per zone. If fitting to a conventional control panel, please verify the quanity per zone with the chosen panel manufacturer. The field of view of the flame detector is shown in Fig. 1 (refer to datasheet PP2399). This also provides information on the size of fire detectable at various distances. The Flame Detectors can also be ceiling mounted, positioned above the anticipated flame source or at the centre of the area to be protected, perpendicular to the floor below. If the detector cannot see the whole of the area to be protected, one or more additional detectors may be required. Refer to the angle of view diagram Fig. 2 (refer to datasheet PP2399) to establish the detector performance. The area of detection is dependent on the detectors height above the likely source of flame. The detector has a 90° conical field of view or 45° either side of the viewing axis centre line. The maximum ceiling height is 20m. If the detector is perpendicular to floor and at a height of 10m then the detector will view a circular floor area below with a 10m radius (20m diameter circle).
