|2600 Series Seismic Sensor
For Industrial & Commercial Applications
This industrial, user-friendly system detects both vertical and horizontal ground movements. The system stores the peak acceleration (in "g") in each axis for up to 15 seismic events. Custom activation points can be set through the user interface menus on the Liquid Crystal Display (LCD). The set points can be returned to their default values at any time through the user interface.
The Liquid Crystal Display (LCD) provides an easy-to-use and easy-to-understand interface.
In meter mode, the LCD display is updated every second with the absolute value of the peak acceleration over the previous second. second. The metering mode can also display the angle of deflection from level in each axis. In this mode, the accelerograph function is disabled and the angle (in degrees) is displayed on the LCD.
The system has two independent relay contact outputs (Form C) for seismic alarm. One set of contacts is latching and will remain in the "activated" position until manually (or remotely) reset. The other contact is a non-latching contact and will automatically reset when the seismic disturbance is over. These contacts can be connected to a control panel, or used to trigger an external device such as a siren or pre-recorded message on a public address system.
Another set of latching relay contact outputs (Form C) is provided for trouble or error indication. This contact will activate if an error is detected during a self-diagnostic check. The cause of the trouble condition will be displayed on the LCD. The relay contact will remain activated until it is manually reset.
