Site Survey
Description
Appendix A: Site Survey
A.1 Description
The site survey allows you to assess and qualify the site for installing the wireless fire alarm sys-
tem. The site survey view in the PC tool allows you to view the Radio Frequency (RF) assessment
of the site. The tool reports the suggested device spacing based on the data collected during the site
survey. This helps to optimize the reliability and performance of the wireless network in the wire-
less fire alarm system.

A.1.1 Conducting Site Survey at the Job Site
The site survey includes two tests:
• Link quality test
• RF Scan Test
The link test can be conducted individually or it can be done followed by the RF Scan test. This
section explains the steps for a link quality test and a link quality test followed by RF Scan test.

Link Quality Test
A link quality test is a quick and repeatable test that provides immediate feedback on the device
connectivity. It is conducted primarily to check if there is an event of pocket loss during data trans-
mission between devices. In a link test, the device addresses are set in the range of 001 to 100.

mission between devices. In a link test, the device addresses are set in the range of 001 to 100.
Basic Requirements
To conduct a link test, ensure that
•
You possess two or more devices.
•
The devices are in factory default condition.
NOTE: The LEDs in the device blink red (single or double blink) upon starting the device if it is in
a factory default condition. Refer to 4.6.4, "Restoring a Device to Factory Default" for more
information on setting the device to factory default state.

Conduct a Link Test
NOTE: The below procedure lists the steps for conducting only a link test. Hence, examples on
the setting the address on devices is explained considering only link test.
the setting the address on devices is explained considering only link test.
To conduct a link test, perform the following steps.
1.
Remove the batteries if any present, from the devices and set the address of the first device as
001.
001.
NOTE: For each subsequent device, use the next highest SLC address. For example, set the
first device address as 001, second device as 002 and third device as 003. The upper address
limit for a device address is 100 while doing a link test.

2.
Bring the first device to the required location to conduct the test.
3.
Insert one battery in to the factory fresh device. After inserting the battery, the LEDs in the
device blink red twice every five seconds, if the device is ready for site survey.
