Jumpers
There are two groups of jumpers on the EA102A-304 Receiver. The first group contains Jumpers P1 through P3.
The second contains Jumpers P4 through P8. The function of each jumper is indicated in the table below:
NOTES:
*
Remove Jumpers P1, P2, and P3 when installed in an outdoor enclosure.
**
Remove Jumpers P4, P5, P6, and P7 for normal operation.
Test Mode
Each EA102A Receiver provides a Test Mode that may be used to check the unit's functionality. The module
goes into Test Mode when Jumper P4 is in place (Jumper P5 removed). In this mode, all test and alarm
receptions will be sounded.
NOTE: The sounder and LEDs (Jumpers P1, P2, and P3) must also be enabled to operate the Test Mode.
Each receiver should be tested using the following method (test only one receiver at a time):
1)
Enable the Test Mode by placing the P4 Jumper across both pins (Jumper P5 removed).
The red LED will turn ON and stay ON during the test. This indicates that power is properly connected
and the receiver is in Test Mode. If the red LED does not come on check the POWER+ and POWER-
wiring to this receiver. Also verify the corresponding transponder bus enable jumper is in place and the
transponder is on and powered.
The green LED will flicker if the receiver is connected to a working transponder. If the green LED is not
flickering verify the BUS+ and BUS – wiring to this receiver (note, this is a rapid flickering).
There will be no data transmitted to the central station. Therefore, the Central Station will report this
receiver as "Not responding" while the receiver is in test mode.
2)
Activate the transmitter from different locations near the receiver.
The red and green LEDs will respond to a received transmission.
If the receiver detected all the packets from the transmission, the sounder will beep three times.
If the receiver detected the transmission, but some of the packets were missing, it will beep once. This
could indicate that the signal is not sufficient from this location.
3)
Remove the P4 Jumper to return the receiver to normal operating mode.
