Verification of installation tightness under asymmetric cut-off. Since this executes free of masking from the consumption flow, it can detect very small leaks.
Peak flow resulting from the building's cooling demand at the provided operating conditions on the warmest day of the year.
The maximum amount of available differential pressure that the leakage protection system may absorb.
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.
When equipped with Option E the WLP-2-BCW can issue an impulse per consumed kWh to an external counter.
WLP-2-BCW with Option E perform energy transfer calculation according to DS/EN1434. Resulting data may solely be used for technical purposes (distribution key), since the system's layout prevents sealing. For the same reason the system is not accredited for energy measurement.
Local protection of a particularly sensitive or exposed location from aggregate water by means of liquid sensors LS-X attached to the WLP system.
Functional description of the point protections, e.g. 'Cable Tray Corridor East', 'Floor Drain Building K5' er 'Cooling Unit Dealer Room 334'
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 the cooling water installation 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.
WLP-2-BCW with option E is equipped with two temperature transmitters attached to two of the WLP computer's eight analog inputs. The remaining six may then be used e.g. for LS-X liquid sensors.

Description of Leakage Protection System for Cooling Water Installation

The cooling water installation of the building is to be equipped with a leakage protection system which continuously monitors the consumption and provides automatic installation cut-off on detection of a leakage. The system must further execute a distinct tightness test of the installation while simultaneously testing the functionality of all its primary components.

Maximum permissible combined pressure loss of all protection system components (flow meters and cut-off valves) at maximum load _____ m³/h: ____ kPa or. ____ mvs.


Connections to external equipment (tick off):
   The leakage protection system comprises a modem (POTS) for alarm dial-out and service
