An isolated section of the installation which is provided with its own flow meter for leakage monitoring, and possibly its own cut-off valve.
Functional description of the installation section, e.g. 'Humidifiers', 'Fire Hoses' or 'Warm Supply Water'
Dimensioning water flow qd  converted into m³/h (DS439).
Specify whether the section must be cut-off on alarm.
Alarms must be transmitted elsewhere for sections without cut-off valve.
Monitoring is forced to high/low consumption phase by external switch.
When a modem is attached, the WLP can be programmed to perform dial-out on alarm to up to four different phone numbers or SMS-pool (in Denmark), while DanTaet can provide swift assistance and troubleshooting by remote control of the WLP.
Whenever a building contains more than one WLP computers, these may be connected in a DCN-network, permitting any computer to utilize an attached modem, and permitting remote control of all WLPs.
The flow meters of the WLP system can be employed as secondary meters by the BMS, saving space and reducing acquisition and installation costs. The WLP can reproduce the meter impulses directly, or supply an impulse per volume unit adjustable 1-1000 liters.
The alarm outputs of the WLP system may be used to indicate system status on the BMS or other technical equipment.
The open BMS protocol of the WLP systems permits data communication with and a degree of remote control from the BMS.
Local protection of a particularly sensitive or exposed location from aggregate water by means of liquid sensors LS-X attached to the WLP system.
Response time of the point protection is adjustable from 1 sec to ½ hour. This permits tailoring the response to prevailing conditions, e.g. enabling the system to tolerate temporary wetness of a sensor during room cleaning procedures.
Specify whether the sensor must cut-off one or more installation branches on aggregate water alarm.
Specify whether the system may automatically acknowledge an aggregate water alarm if the sensor subsequently dries up.
Specify the length of cable between sensor and computer - this should possible be part of the tender for electrical installations. An LS-X sensor may be equipped with up to 10,000ft of the suitable type of cable.
This form is printed, filled and used as a tender document enclosure. Employ your browser's 'Print Preview' and 'Scale' functions to fit the form into one sheet of paper. Ensure no baloon help is visible before starting the printout.
Functional description of the point protections, e.g. 'Cable Tray Corridor East', 'Floor Drain Building K5' er 'Cooling Unit Server Room'

Description of Supply Water Leakage Protection System

The supply water installation of the building is to be equipped with a leakage protection system which continuously monitors the consumption and provides automatic cut-off on detection of a leakage if a cut-off capability is present. The system must perform regular self-testing of its primary components.
The leakage protection is divided into the following primary branches, which are individually protected:

Branch      Identification
Nom. Load
Qn m³/h

Connections to external equipment (tick off):
   Monitor phase control via door switch/burglar alarm
   The leakage protection system comprises a modem (POTS) for alarm dial-out and service
   The leakage protection system comprises a DCN data communication network connection
   Meter flow impulses are (scaled and) repeated to the BMS
   Status/alarm outputs are wired to the BMS/building alarm system/other...
   Communications port is wired to the BMS

Options (tick off):
  The leakage protection is extended with point protection using liquid sensors situated as follows:
