Page 6: Introduction
Introduction Floodline leak detection systems are designed to detect water/liquid leaks within buildings. The alarms generated by the Floodline systems allow early action to be taken to prevent damage, reduce disruption and limit loss caused by unnoticed leaks. Floodline systems are installed in sensitive and critical areas to give early warning of leakage from any source and typical installations include modern offices, call centres, historic buildings, communication rooms, dealing rooms, etc. - Page 7 When a zone or certain system alarms are detected a full text message of the nature of the alarm is displayed on the control unit’s LCD, a red LED indicator flashes and buzzer sounds. Any person pressing the MUTE button can silence the buzzer, but this does not cancel the alarm or clear any of the visual alarms.
-
Page 8: Floodline Sensors
In the event of an alarm the appropriate relays activate providing a “clean contact” output for connection to a remote monitoring system, BMS etc. Although the mute button being pressed can silence the buzzer the relay outputs can only be cancelled by using the control unit’s menus. The standard output relays can also be linked and the three options available are: 1. -
Page 9: Principle Of Operation
Principle of Operation The Floodline system works from the principle that water, or other conductive liquid must touch one or more of the sensors for an alarm to be activated. (Any liquid will activate the OIL Sensor). The system essentially detects differences in loop resistance on each of its zone inputs. The leak detection and system fault alarms are activated when the loop resistance falls between, below or above set limits as detailed below. -
Page 10: Mounting Floodline 128 Base Unit
A retaining clip is provided with the IEC plug to ensure it is not accidentally disconnected. The Floodline 128 must be provided with an EARTH (Ground) to ensure correct operation and for safety reasons. If the base unit is not correctly earthed Andel Limited cannot guarantee correct operation of the system. -
Page 11: 32 -Zone Leak Detection Module
32 –Zone Leak Detection Module The 32-zone leak detection module are house in card slots within the base unit and connect to the motherboard via a ribbon cable. A read indicator on each module shows that it is connected. The base unit can handle up to four 32-zone leak detection modules giving a total of 128 zone if required. - Page 12 Alarm Active Indicator Mute Button Display Window Up Scroll Key Menu Access Key Menu Key Down Scroll Key Enter Key Leak Alarm A leak alarm is generated on a per zone bases when the loop resistance of the zone falls below the set limit as set by the engineer at time of commissioning.
-
Page 13: Short Circuit Alarm
Short Circuit Alarm A short circuit alarm is generated on a per zone bases when the loop resistance of the zone falls below 1k ohm. When a short circuit alarm is generated the audible alarm in the control unit is activated, the alarm indicator on the control unit flashes and the display window indicates the zone in which the alarm was activated as shown below. -
Page 14: Module Communications Failure Alarm
Module Communications Failure Alarm A module communication failure alarm is generated on a per module bases (module 1 to 5) when communications between the base unit’s motherboard and one of the 32 zone leak detection modules or communications module has failed. When a module communications failure alarm is generated the audible alarm in the control unit is activated, the alarm indicator on the control unit flashes and the display window indicates the module number as shown below. -
Page 15: Display Disconnected Alarm
Display Disconnected Alarm A display-disconnected alarm is generated if the physical connection between the base unit and the control unit is lost. When a display disconnected alarm is generated the audible alarm within the base unit pulses, the self-test relay activates if relays are armed, and the “Display Disconnected” indicator on the front of the base unit activates. -
Page 16: Remote Disconnected
Remote Disconnected This alarm is generated when the remote alarm (if connected) is disconnected. When a remote disconnected alarm is generated the audible alarm in the control unit is activated, the alarm indicator on the control unit flashes and the display window indicates that the remote has been disconnected as shown below. The self-test relay in the base unit will also activate if the relays are armed. -

Page 29: Single Zone Detection (Sensing) Tape
Single Zone Detection (Sensing) Tape Introduction The Single Zone Detection Tape is the simplest of all the Floodline detection sensors and is a low-cost solution where a large amount of basic leak detection is required. It is very absorbent and will therefore react to the smallest amount of liquid. -
Page 30: Returning Sensor To Use
Returning Sensor to Use The single zone detection tape can be wetted and dried any number of times as long as it does not become contaminated with a substance which irrevocably changes its electrical characteristics. Eg.vending machine syrup, some chemical floor treatments, paint etc. The detection tape will dry out naturally and the effected part of the cable must be completely dry before the zone can be reset. -
Page 31: Fixing
Fixing The detection cable is laid flat on the floor in the pre-determined pattern and special 4 Zone Junction Boxes are used to connect the detection cable “string” to the leader cable coming from the control panel and at the start of each subsequent zone in turn. A further junction box is used at the end of line. The detection cable is usually fixed with screwed “P”... -

The multi-8-zone detection cable should not be tie-wrapped to pipes (– use multi-4 Zone detection cable instead) As with all Floodline sensors water contacting the cable changes its electrical characteristics (resistance) and when the change is sufficient the Floodline control panel, to which the sensor is connected will generate the appropriate alarm. - Page 34 Please note the 2 black core of the detection cable must not touch, as this will cause a short circuit alarm because the back is not an insulator.

The M8- detection cable should not be tie-wrapped to pipes (– use M4 detection cable instead) As with all Floodline sensors water contacting the cable changes its electrical characteristics (resistance). When the change is sufficient an appropriate alarm will be generated at the Floodline panel. The M8 detection cable has an outside diameter of 4.5mm. -
Page 37: Returning Sensor To Use
Note: The zone numbers are for the zones on the string. When more than 8 zones are used you simply connect the cores into the appropriate zone numbers (i.e. zone 1+, - can be wire to zone 17 +, - or any other zone). -
Page 38: Fixing
Where it is not possible to fix to the wall surface or other convenient surface the assembly can be bolted to struts or other fabricated bracket and special right angle supports are available from Andel. The Horizontal Point Sensor must be used in conjunction with a guard plate and can be mounted on any flat surface with the tips of the sensing probes facing downwards. -
Page 39: Returning Sensor To Use
A diagram of the connection details for the point sensors is presented in Appendix E. Once the point sensor, or last sensor in a string has been connected to the leader cable the 1M “sleeper” resistor, from the zone input terminals in the control panel, should be fitted to the output terminals of the point sensor. -
Page 40: Returning Sensor To Use
Returning Sensor to Use Flexi-pad sensors can be wetted and dried any number of times provided the sensor element/ fabric cover is not contaminated with a substance that irrevocably changes its electrical characteristics. An example may be vending machine syrup, chemical floor treatments paint etc. After activation, the fabric cover can be replaced with a spare or removed for drying. -
Page 41: Oil Sensor
Oil Sensor Introduction The Floodline oil sensors can be used with a Floodline Control Panel to provide a dedicated oil leak alarm system or as part a larger water leak detection system. The oil sensor is usually mounted vertically and activates when oil (or any other liquid) touches the infra-red sensing dome at its base. -

Page 43: Using Other, Non-Liquid, Types Of Sensors With The Floodline System
Using other, non-liquid, types of sensors with the Floodline system The flexibility of Floodline allows certain types of detection devices other than water/liquid sensors to be connected to the system. These could be temperature or humidity sensors and some smoke detectors etc. There are certain restrictions which must be observed such as not exceeding the available power and the ability to latch, or hold, a set of clean contacts for sufficient length of time for the Floodline Control Panel to recognise the alarm. -
