The GRI 2600 is a wired flood sensor designed to trip an environmental zone on a security system. Ideally, this device is wall mounted near the lowest point in your home or business. You can also install this sensor in areas near washing machines, sinks, and other appliances that tend to cause flooding. It is a very simple device. It is a contact with two metal probes. When these are shorted by water the zone will trip and send a fault back to the alarm panel.
This is a 4-wire sensor: 2 power connections and 2 data connections. The power connections can be landed on the alarm panel's keypad bus. This is 12VDC+ and a ground connection (i.e. terminals 4 and 5 on a VISTA-20P). The data connections should be landed on an open zone. You can supervise the wire by wiring a resistor in series at the end of line at the flood probe. Then set the input type to EOLR. If you do not use a resistor set the zone as NC (normally closed).
Generally, the zone is configured in a way that it is monitored 24/7 and does not rely on the armed state of the system. This way if it detects water at any time (even while the system is disarmed) you will be notified. For Honeywell panels, we recommend configuring the zone as 24 Hour Auxiliary. This will result in local keypad alarms and phone calls from the central station if you are monitored.
The GRI 2600 is an affordable alternative to the Honeywell 5821 which offers wireless temperature and flood detection. Although the 5821 is wireless back to the panel, you will still need the 470pb wired locally to the 5821 for flood sensing. The 2600 is an easy option if you are able to run a wire directly back to your alarm panel which generally is installed in the basement near commonly flooded areas.
