Model 10C
4.7 Test
The 10C Controller “TEST” provides a means of checking the external alarm system by artificially setting off
Relay Outputs without having to force them on/off through the external sensor input to the Controller. The
“TEST” consists of an internal test variable that starts at zero and increases to full-scale range and then
decreases back to zero. The internal variable is fed into the internal Controller processing as if it were an
external sensor signal. During this test the 10C Output Current stays at nominal zero reading or 4mA. As the
internal test variable sweeps through alarm set point values, the appropriate triggering of alarms should occur.
This allows the verification of proper operation of the relays, the connection through to the backplane, the
wiring, the power source, and the actual Horns, Strobes or other actuated devices. The alarm configuration
with regard to set-point thresholds, direction, latching, coil energize setting, and silenceable setting, can all be
tested for desired performance. Performance results deviating from expected desired results should be
evaluated for cause, whether equipment malfunctions, or incorrect settings or bad configuration.
The “ENT” pushbutton can be used to enter the “TEST” function and “TEST OFF” will display. The “ENT”
pushbutton can be pressed again and the test begins with the displayed text: “TEST ON”. Then the display
will start displaying the internal test variable value, starting at zero and increasing. When the display returns
to zero, the test in complete. The “ESC” pushbutton can be used to return the display to the menu selection or
back to display Normal Operation. The “ESC” pushbutton can be used during the test to exit the test.
NOTE: Alarm Outputs that are latched during the test remain latched after the test is finished
and are not automatically reset.
