GRI LIQUID LEVEL DETECTOR - STAND ALONE DETECTS NON-VOLATILE LIQUID LEVELS, POWERS 10 SENSORS The G.R.I. 2826FS 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 new 2826FS from GRI 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 2826FS automatically places itself in a safe mode to help prevent danger to devices, property and/or people. This safe mode keeps the zone assigned to the 2826FS in an alarm condition. This causes an authorized person or an alarm technician to physically inspect the 2826FS and replace the battery, prior to resetting and re-arming the system. The G.R.I. 2826FS 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. INNOVATION, QUALITY AND SERVICE At G.R.I. only the finest raw materials are used in producing a contact switch you can install with confidence. GRI's Purchasing Department requires vendors to meet or exceed specifications on reeds, plastic, wire and potting material. Their name and logo are also found on products other than security switches. G.R.I. produces the Air Traffic Control Board used by the F.A.A. in their control towers across the nation. One of GRI's pushbutton switches is a special design developed specifically for the F.A.A.’s use. GRI's Engineering Department makes use of in-house CAD/CAM to design not only security contacts, but custom designed Keyboards and Switches, built to rigid specifications for applications in Military, Aerospace, Industrial and Medical Fields.
