The following site-specific information helps with the planning and design of a wireless site. You can use the information that you collect in case you require to troubleshoot implementation. This information is meant as a guide only. The information does not all need to be known, or completely filled out to make design and installation decisions, but a better site understanding typically leads to a better performing design.

It is recommended to perform the site-survey with use of the ZFR-HPSST-0 (Field Controller Bus) Survey tools and following the instructions provided.

  • It is recommended to test as close to the wireless equipment to be installed (temporary mount the tool on a ladder in the probable location of a ceiling repeater/coordinator, position the sensor where the router will be located).
  • Record bidirectional communication from the tool – sensor pair. Due to differences in the signal reflection, there could be different LED blinks seen across devices.
  • Note down the blink count along with the test-route taken.
  • Perform the site-survey during occupied hours.
The following project and site information is representative of useful information to collect to correctly estimate and design the wireless solution.
Note: The fields marked with an asterisk (*) are considered mandatory and required for evaluation while the rest are optional.

Question Site response (Yes / No / Specify)
Are there existing wireless solutions on-site that could interfere with the Johnson Controls wireless solution? *
Does the building tenant’s plan include wireless solutions that could interfere with the Johnson Controls wireless solution? *
Will the building’s Wi-Fi solutions be unmanaged? *
Note: Multi-tenant office buildings often have independent IT departments that do not coordinate Wi-Fi usage
Does the customer require validated environment (21CFR Part 11) compliance? *
Are non-Johnson Controls controllers in the network targeted for TMR Wireless (is interoperability with third party wireless devices a requirement)? *
Does the customer require direct management, prohibit, or restrict any wireless system on their premise?
Do any BAS system applications prohibit an occasional offline or delayed communication response? *
