Water Sensor – 319.5 MHz


The ELK-319WA is a Supervised, Wireless Water Sensor designed so that the transmitter mounts on a wall or other flat vertical surface, and the remote probe is placed in the location where water leakage is most probable.

Moisture forming a bridge between the two metallic contacts on a remote probe is all that is needed for the unit to signal an alarm condition. The output on the ELK-319WA will remain in alarm state until the moisture bridge is broken. As sensitive as the water sensor is, it will not alarm due to high humidity or condensation. The ELK-319WA is ideal for use in homes, offices, computer rooms, warehouses, etc.

Compatible with E27 Alarm Engine, M1 Controls, and other systems that support 319.5 MHz wireless devices.
