» BMS Interface Water Leak Detection module : BMS WaterBug and WaterBug +Plus

The BMS WaterBug is a sophisticated liquid leak-detection alarm designed as a stand-alone module which can be powered from mains or low voltage power supplies. WATERBUG units are specifically designed to operate with Building Management Systems (BMS) and have been widely used in Switching Centres, IT Complexes and Telephone Exchanges throughout UK, Europe, USA and Africa.

The WaterBug+Plus additionally has three LED Indicators advising Power On, Leak Alarm, and Line Fault, and also has an internal horn and an external mute button. The audible alarm is activated by any abnormal condition, ‘latches-on’, and is silenced by pressing the mute button. When the mute button is pressed the system will automatically reset, requiring no further operator input, but alarm lights remain on until the condition clears.

The WaterBug water detection circuit uses a bi-directional  “alternating current” field sensing signal to ensure that sensors are not subjected to oxidation or erosion during operating conditions. A sensitivity adjustment pot allows on-site adjustment of water detection sensitivity to suit the application. The WaterBug can be powered from the standard mains power supply or from a 12-24V AC/DC supply. A 'No-Volt' output signalling relay is provided rated at 240VAC 2amp with 'Normally Open/Closed' change-over contacts. Additional optional ‘power’ fault relay can signal loss of power and ‘cable fault’ can signal a break in the monitoring line. 

The WaterBug is designed to monitor for water leaks from Aqualeak sensor cables or tapes, sensor pads, sensor probes, and other specialised Aqualeak sensors. Leader Cable distance between the WaterBug and the Sensor/s, or the maximum linear sensor cable sensing distance, should not exceed 50m. WaterBug units can fitted directly into plant control panels to prove liquid leak detection in pump rooms, power containers and plant areas. WaterBugs can be provided complete with a Sensor Pad or Sensor Probes pre-fitted to the base or side of the housing for direct wall/floor mounting in bunds and drip trays.
