Overview
The AT-MNC-001 is a microprocessor-based master controller for water and liquid leak detection. A single detection channel supervises multiple locating and non-locating Sensor Interface Modules, giving the exact leak position along the cable when locating modules are used.
Alarms are signalled locally through the display, LEDs and built-in buzzer, through four potential-free relays, and to the BMS over Modbus RTU (RS485). The controller can be networked with the ATYSEN Intelli Panel for graphical representation and detailed location mapping.
Key Features & Advantages
Precision Leak Detection
Instantly detects the presence of water or conductive liquids along the sensing network through Sensor Interface Modules and leak sensing cables.
Accurate Identification
Accurate identification of cable break faults.
Sensor Module Connectivity
Connects up to 50 Sensor Interface modules in a daisy chain, covering a 1500 meter sensing network.
Visual Display
OLED display along with status LEDs for leak and break indication.
Audible Buzzer
In-built audible buzzer alarm for leak and break, with provision to silence it.
External Hooter
The internal buzzer can be switched off and an external hooter wired through the relay outputs.
Digital System Integration
Fully compatible with the ATYSEN digital panel and controllers.
Strong, Reusable and Low Maintenance
Flame retardant ABS enclosure, designed for repeated use without performance degradation.
BMS Connectivity
Sends real-time alarms and status reports to Building Management Systems.
High Sensitivity and Reset
Immediate response upon contact with water or conductive liquids. Reset within seconds after leak removal.
