Site Survey
seconds. The results appear in approximately 20 seconds and the LEDs on the first device
change to solid red. This is due to the absence of a lower-addressed device with which to form
a pair. This result is expected from the 1st device when a link quality test is performed.
5.
Bring the second device (002) to the second location and repeat steps 3 and 4.
6.
The device will conduct a link test to the next lowest address; in this case device 001. The
result of the link test from 002 to 001 is displayed by the LEDs on device 002. Refer to
Table B.1 below.
7.
Once the link test is complete between 002 and 001, continue for address 003, 004, etc. for all
devices that will be used in the site survey. This test may be repeated any number of times. For
devices addressed to 101 or higher, the test must be repeated, if desired, within five minutes of
the last concluded test or the devices will start an RF scan 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 Survey 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.
