- Detects Non-Volatile Liquids - For Use With Wireless Transmitters - Microprocessor Controlled - Installs Easily - “C” Form Relay Contacts
|
APPLICATION:
The G.R.I. 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 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.
DESCRIPTION:
The G.R.I. 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 microamp
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.
