George Risk Industries' GRI 2826 - detector is an internally powered, microprocessor controlled device that samples the conductivity between any two adjacent sensor points located on the bottom of the device. Power consumption is less than 1 micro-amp while in the standby mode. This allows for an extended duty cycle. Relay contacts are latched in an open or closed position based on the conductivity measured between the sensors. eXternal wire connections are provided to allow access to the C form relay contacts for output control of an external device.
APPLICATION:The GRI 2826 - detector was designed in response to a direct request for a small electronic sensor capable of detecting non-volatile liquids in remote hard to reach locations. The sensor, in conjunction with your favorite wireless transmitter, can be used to detect and report the encroachment of non-volatile liquids into an isolated sensitive location.
The GRI 2826FS - provides remote probes plus a fail safe capability. When the on board battery expends the last of its power, 3 to 5 years under normal conditions, the GRI 2826FS automatically places itself in a safe mode to help prevent danger to devices, properly and/or people. This safe mode keeps the zone assigned to the GRI 2826FS in an alarm condition. This causes an authorized person or an alarm technician to physically inspect the GRI 2826FS and replace the batter, prior to resettling and re-arming the system.
