Step 9. Sensor Shunt

TM 5-6350-275-24&P

3-131 Continued

The keypad starts selecting and controlling each sensor. During the test, the display changes to the following:

WLK SLF ZNE SGL

PIR 1 ST OK

The ST indicates self test. If the test is successful, the ST changes momentarily to SG1 SELF TEST OK to indicate an

alarm tested good.

If the sensor fails the test, the display changes to "Test Failure" momentarily.

At the end of the sequence, if all sensors test OK, the keypad displays a test completed message.

Step 9. Sensor Shunt

With the required access level, you can selectively shunt sensors in the alarm state to secure areas if a sensor fails.

Only alarm indications can be shunted. Sensor tampers must be corrected. Only zone and perimeter alarms can be

shunted. Sensors classed as 24 hour alarm cannot be shunted.

Step 10. Applying Shunt

To apply a shunt to a sensor, log into the keypad to the first menu level by entering your PIC number followed by GO.

Select F1 (SNT) with either F3 (ZNE) or F4 (PER) to list sensors defined in the zone. The display scrolls through the

points. Use F3 (HALT) to stop the display at the sensor to be shunted. F4 (OPER) applies a shunt to the sensor. The

display appears as:

TST SNT CLR

PIR 1 SH OK

The SH indicates a shunted sensor.

After a time-out period, the display returns to the second and the first level menu.
