The battery-powered probe connects to Packet Power's E306 environmental monitor that supports external probes via a 2 meter wire that can be extended as far as 15 meters. When the leak detector senses the presence of water or other similarly conductive liquids it communicates to Packet Power's EMX monitoring application or any DCIM or BMS that supports open protocols such as Ethernet/IP, SNMP, Modbus, MTConnect, BACnet/IP and MQTT.
Mounting
The probe mounts horizontally using an adjustable mounting bracket that allows detection from 1/32 of an inch up to 17/32 of an inch. The tabs on the side of the water detector fit into the slots on the bracket.
The mounting bracket mounts to a drip pan or any flat surface by either the attached adhesive strips or using two #6 or #8 screws.
Notice: Attach the probe to the mounting bracket before attaching the mounting bracket to the desired surface. The adhesive is very strong and is not easily removed once attached.

Replacing Batteries
When the battery is low, a yellow warning LED will begin to flash and an audible alarm will sound every 300 seconds to alert that it is time to change the battery. Using a large flat head screw driver, turn the battery cover 1/4 turn in the direction of the arrows on the cover. Remove the battery cover by lifting it up. Remove the coin cell battery from its compartment. Insert a new 3V CR2450 coin cell battery in the compartment with the positive 
side of the battery facing up. Replace the battery cover and twist the cover using the large flat head screw driver in the opposite direction of the arrows on the cover.
Operation
After mounting, connect the probe to any Packet Power environmental monitor that supports external probes. The leak detector can co-exist with temperature monitoring probes. Once connected, the probe is ready for operation. Water is detected when it bridges the two conducting strips on the bottom of the unit. Upon detecting water, the relay contact will close and a red LED will begin to flash. An audible alarm will begin to chirp until the water bridge between the conducting strips evaporates. After water evaporates, the relay contacts will return to their normal state.
LED Indicators
Yellow: On when low battery condition is detected
Red: On when water is detected
Interfacing with a Wireless Monitor
The leak detector interfaces with Packet Power Environmental Monitors with external probe ports. The Leak Detector is equipped with a two wire connector that interfaces with any port of the wireless Environmental Monitor.
Modbus Interface
To acquire the status of the leak detector via Modbus TCP/IP you must have a Gateway (version 4 / EG4) that is licensed for Modbus TCP/IP. Modbus register maps and expressions used for the leak detector can be found here.
