BREEAM Water Leak Detection – Type BLDA1-2

Designed to meet the requirements of BREEAM WAT02 and WAT03 water leak detection accreditation. BLDA1-2 detects major leaks within the building. The system is fully user programmable with output alarms and onward meter pulses for external water flow metering by a Building Management System.

Water Meter Sizes that can be used?

The singel zone BREEAM Water Leak Detection – Type BLDA1-2 and the two zone BREEAM Water Leak Detector – Type BLDA-2 can use:

Water meters ranging in size from 1/2″ (15mm) to 2″ (50mm) and Flanged Water meters from 2 1/2″ (65mm) to 20″ (500mm)

When does the BLDA1-2 go into alarm?

The Alarm Panel will not only flash but also emit an audible alarm in the event that the water flow surpasses a predetermined level. For example, if the water flow rate exceeds 140L in a 10-minute interval, the Alarm Panel will activate.

Additionally, the Alarm Panel will go into alarm when there has been a constant flow of water over an extended time period. For example the Alarm Panel can be set to check if there has been no water flow for 2 minutes in a five hour time period. This means that an Alarm will be triggered if there is no break in water flow that lasted longer than two minutes in the five hour time window.

Advantages of using the BLDA1-2 BREEAM Water Leak Detection

User-friendly – With its large digital display, you can easily monitor the current water flow through the supply water pipe.

Fully Programmable – Push buttons inside the Alarm panel allow you to adjust the criteria required for your building. This will include:

1. Size of the water meter (1L/pulse, 10L/pulse, or 100L/pulse).
2. Threshold of water usage (L/time) for both High and Low periods of water usage.
3. Continuous flow alarm time periods.
4. High Flow time periods for different days of the week.

Control – Use the ‘Mute’ button to silence the audible warning. Press the ‘Water On’ button to reset the system and turn the water supply back on.

BREEAM Criteria – the BLDA1-2 Alarm is WAT 02 and WAT 03 accredited.

Flexibility – the Alarm Panel can be easily connected to a Building Management System. For greater control you have the option of installing a ball-valve to shut off the water supply. Additionally, you can choose to have a Sounder Beacon and a SMS Text Messaging Unit fitted.

Why we use Actuated Ball Valves

CMR Electrical were one of the first Water Leak Detection companies in the UK to use Actutated Ball Valves. Read this article to discover the Benefits of Actuated Ball Valves in water detection systems. Find out why we rarely use Solenoid Valves.
