Troubleshooting
MPS-4100 product guide • • • 3 - 7
2. Connect a set of headphones to the 1/8 in. local audio plug (P3) on the
Receiver circuit board.
When the microwave field is disturbed, an audio tone is generated. The audio
tone increases in pitch and volume as the disturbance moves through the
field.
3. Listen to the headphones while observing the zone. Look for a correlation
between any activity in or near the zone and an increase in the audio output.
If a potential problem is identified, correct the problem and retest the zone.
4. Decrease the sensitivity slightly and retest the zone. Continue reducing the
sensitivity setting until you achieve an acceptable level of detection without
an unacceptable false alarm rate.
Silver Network/StarNeT 1000 Communication Interface Card
The Communication Interface Card includes 12 diagnostic/status LEDs to assist
troubleshooting. Test the MPS-4100 according to the directions in the alarm
display and control system. Using a two-way radio for communication, have a
technician monitor the LEDs on the CIC while an operator conducts the test. If
the Communications Interface Card is faulty, power down the card, label and
disconnect the network communication cables, and remove the faulty card. On a
replacement CIC, set and verify the dip-switches for proper configuration, install
the new card and reconnect the network communication cables on the new card.
Return the faulty card to Senstar after obtaining an RMA number.
