Single & Two Zone Oil Detection Units

The FLD range has been designed to monitor critical areas for oil leaks and spillages via spot optical sensors. Up to 10 sensors can be connected to each zone.  The unit includes an audible warning device, mute push button, flashing 8mm red alarm lamps and 8mm Control live green lamp.  Once an oil leak has been detected, the controllers red “Alarm” lamp will start to flash, the audible warning device will start and the common alarm relay will close. The unit will remain in this condition even if the oil is removed from the sensor. Only muting the alarm will stop the sounder, turn on the lamp permanently and de-latch the alarm. If oil is removed from the sensor before pressing the “Mute Alarm” button, after Muting the alarm lamp will extinguish indicating that oil is no longer present and the common alarm relay de-energise. However if oil is still being detected only the audible warning will stop leaving the lamp permanently on and the relay energised. Only when the oil has been removed will the lamp extinguish and the relay de-energise. AllFLD units have a common alarm set of volt free contacts for onward signalling to Building Management Systems, telephone dialler, control systems and shut off valves.

Features

• Large indication LED lamps for ease of Alarm identification from a distance
• On board audible warning device to alert local operators of a problem
• Alarms latched until Mute operated to give indication of transient water leaks
• Common alarm relay to onward signal to a BMS or used to shutdown Oil valves
• Lamps, relay and Horn test Facility to ensure that the unit is working correctly
• Small foot print, wall or surface mounted

2 Zone Oil Detection System With Battery Backup

This unit contains a battery to allow the unit to operate during a power cut. The life of the battery is dependent upon the number of sensors that are connected but would be in the range of 5 and 10 hours. The size of the housing is size 200mm x 150mm x 80mm deep, Surface mounted, cable entry/exit via glands on any side or through the back. Input power to the unit 230VAC, but any AC voltage can be catered for. Sensing voltage is 5 Volts DC. Large indication LED lamps for ease of Alarm identification from a distance. On board audible warning device to alert local operators of a problem. Common alarm relay to onward signal or used to shutdown valves. Lamps, relay and Horn test Facility to ensure that the unit is working correctly. Small foot print, wall or surface mounted.

Four Zone Oil Detection Unit With Events History

The FLD4 has been designed to monitor four independent zones in critical areas for oil leaks via optical sensors. Up to 10 sensors can be connected to each zone. The unit contains an audible warning device, Mute push button, History & history Exit buttons and a back lit alphanumeric display. A non-volatile event history is included as standard to show the past 250 events. This can be used to identify sensitive areas or faulty equipment. When oil is detected by one of the zones, the display will start to flash with the location, the audible warning device will start and the zone alarm relay closes. The unit will remain in this condition even if the oil is removed from the sensor. Muting the alarm will stop the sounder and the display flashing. If oil is removed from the sensor before pressing the “Mute Alarm” button, after Muting the display will revert back to its normal state indicating that oil is no longer present and the zone alarm relay will de-energise. However, if oil is still being detected only the audible warning will stop leaving the location in the display and the zone alarm relay energised. Only when the oil is removed from the sensor will the display revert back to its normal mode.  The FLD4 as standard has an individual relay for each zone with a normally closed set of volt free contacts. All four relays can be used to individually onward signal to a Building Management Systems, telephone dialler, control systems and oil Shut Off valves or can be wired together to give a common alarm output.
