Three Zones Of Integrated Leak Detection
The BMS-LD3Z provides three zones of RLE’s patented leak detection that directly integrates via protocols into any building management system (BMS) or alarm monitoring system.
Pair the BMS-LD3Z with RLE’s SeaHawk sensing cables and spot detectors to monitor for conductive fluid and caustic chemical leaks and integrate this information directly into a BMS or BAS.
What Sets The BMS-LD3Z Apart?
- Designed specifically for system integration, the BMS‑LD3Z leverages robust protocol communications to communicate with any Modbus RTU or BACnet MS/TP system.
- Notifies users quickly when an alarm condition is met.
- Zone leak detection system alarms when water comes into contact with the attached sensing cable or spot detector. It is the right fit for spaces where sensing cables and spot detectors are visible so leaks can easily be located.
- A supervised system, the controller continuously monitors the cable for leaks, breaks, and disconnects and sends an alarm notification when one is detected.
Key Features
- No user interface or separate software required – integrates directly with existing BMS and alarm monitoring systems
- Enclosure mounts in a panel, on a DIN rail, or on a wall
- Incorporates RLE’s patented leak detection technology into any existing BMS or alarm monitoring system
