Results of a Link Quality Test
The following table explains the LED patterns before and during a link quality test.
The LED pattern for a link quality test will continue to be displayed until the device is tampered or the batteries die for a device that is
addressed 100 or lower. For devices addressed 101 to 150, the result will be displayed until the device starts the RF Scan.
To repeat the link quality test, toggle the tamper state. To toggle the tamper state on a detector, twist the detector in the base counter-
clockwise as if removing the detector from the base, then twist it back in clockwise to lock it in. To toggle the tamper state on a module,
remove the faceplate and then reconnect it. Once the device is tampered, it will return to the pending site survey state. Once the tamper is
cleared, the link quality test will be restarted. Only the results for the last link quality test are retained.
After a Link Quality Test
Retrieve the link quality test results for devices 001-100. To retrieve the site survey results, refer to the topicB.1.3, "Retrieving Site Sur-
vey Results"at the end of this section. For devices 101-150, wait to retrieve the link quality results until the device starts an RF Scan test.
B.1.2 RF Scan Test
A Radio Frequency scan test is conducted to assess and measure the background noise and interference from other wireless systems if
any, in the site. The RF Scan test can be conducted individually or following the link quality test. An RF Scan test will be conducted for
any device with an SLC address set between 101 and 150 at the end of a Link Quality Test.
Conduct an RF Scan Test
To conduct an RF scan test, follow the same procedure for a link quality test. However, the device addresses for an RF scan test must
start at 101 and have the subsequent devices address set as 102, 103, etc. Each device will conduct the link quality test as described
above, then transition to the RF scan test 5 minutes after the last link quality test is performed to or from that device.
If several devices are being tested, it is possible that some devices will start and complete the link test and progress to the RF scan test
while other devices are finishing the link quality test. The RF Scan test may take up to 70 minutes. The time remaining and the test status
are displayed at the device using the LEDs. The LED patterns are shown below.
Status of an RF Scan Test
State Pattern LED Results & Description
Site survey pending Double blink every 5 seconds Red Device is tampered, ready and waiting to start a site survey link
quality test
Link quality test in progress Single blink every ½ seconds Yellow Transmission of data to another device.
Link quality test complete On steady Red Failure - no data received
Link quality test complete Single blink every 5 seconds Red Poor - partial data received or signal strength measured lower
than the acceptable limit for a primary or secondary link (-81dBm
or lower)
Link quality test complete 2 blinks every 5 seconds Green Good - all data received at a signal strength acceptable for a
secondary link but not for a primary link (-66dBm to -80dBm)
Link quality test complete 3 blinks every 5 seconds Green Great - all data received at a signal strength acceptable for a
secondary link and marginally acceptable for a primary link
(-51dBm to -65dBm)
Link quality test complete 4 blinks every 5 seconds Green Excellent - all data received at a signal strength acceptable for a
primary link (-50dBm or better)
