Zone Leak Detection

Many situations require monitoring large areas for the presence of water. The Darwell AT1-M modular zone water detector module provides an excellent solution for these needs. This unique technology combines proven reliability with the utmost in flexibility. The low maintenance sensing cable provides the AT1-M with the suitability for a wide range of applications, including:
· Perimeter monitoring
· Pipe leak detection
· Under-floor detection
· Air conditioner vicinity monitoring

Sensing Cable, AT1-15M, AT1-25M, AT1-30M, AT1-50M
Used in conjunction with the AT1-M module this unique sensing cable is designed to absorb moisture and activate the AT1-M's output relay when water levels are sufficient to complete an electrical circuit. Best of all, the sensing cable is non-destructive, so that when the water evaporates, the unit may be automatically reset with no need for cable replacement. Cables can be coupled together up to 100 feet.

Features include:
· Non-destructive sensing cable
· Durable mesh cloth construction
· Self locking cable connectors

 

AT1 Zone Detection Module

 

The AT1-M is a Modular Zone Water Detector module used with modular zone (AT1-XXM) sensing cable. The AT1-M can be operated with 12-24 AC or DC voltages. For application flexibility, form "C" relay points are provided to connect to a MPR, GMP or similar monitoring system. A galvanized steel enclosure is standard. The AT1-XXM sensing ribbon is designed to absorb moisture and activate the alarm signal when enough water is present to complete the electrical circuit.
