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
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.
•
The green LED will flicker if the receiver is connected to a working transponder.
•
There will be no data transmitted to the central station.
•
The central station will receive a "not responding" failure.
2)
Activate the transmitter from at least five different locations near the receiver.
•
The 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.
Testing Receiver Spacing
Receiver Spacing Mode is enabled with Jumper P5 in place (Jumper P4 removed). This mode is exactly the
same as the Test Mode above, except that only transmissions with an adequate receive margin are sounded.
This indicates the maximum acceptable spacing of receivers. Use the following procedure to test the spacing of
receivers:
1)
Mount the first receiver.
2)
Take the second receiver and a transmitter a distance away from the first receiver.
3)
Activate the transmitter.
4)
If Receiver 1 sounds the test beeps, Receiver 2 is within range. Repeat this test until Receiver 1 no longer
sounds the test beeps. Move back to the last location where Receiver 1 received the test beeps. This
location marks the maximum spacing between receivers. Mount Receiver 2 at this location or closer to
Receiver 1.
NOTE: Do not use the Test Mode (Jumper P4) to determine receiver spacing.
