Marine Series 65 Base Mounted UV Flame Detector

Product code: 55000-026MAR

55000-026MAR - Marine Series 65 Base Mounted UV Flame Detector
The Marine Series 65 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.

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 recognised 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.

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. Full a full list of applications for Apollo Flame Detectors, please refer to PP2409, available on request.

Additional Information

Note: When using the detector the following must be avoided; outside viewing, UV lamps, electrical parking, welding and sources of radiation, UV light sources, prolonged ambient temperatures above 60°C and obstructions to the field of view. ACCESSORIES A portable Flame Detector Test unit is available, part number 2960 0 -226. Adjustable mounting bracket, part number 29600-458 (comes complete with Deckhead Mounting Box). Deckhead Mounting Box, part number 45681-217. INSTALL ATION 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 quantity per zone with the chosen panel manufacturer.
