Title:                     Third Party Test

Owner:                Alexandria Real Estate Christopher Clement

Daswave was asked to perform the required Third Party Inspection for the ERCES (Emergency Responder Communication Enhancement System) per CFC (California Fire Code) section 510.4.11 through 510.4.1.3 and SDFD bulletin dated 9/22/2023 for design, installation and testing.

This project was for a five-story building where Leidos built for office space and lab testing.  The top three floors were open office space with private offices, cubicles and conference rooms.  The bottom two floors were for lab testing for Leidos military sector of their business.  The bottom two floors were heavy with RF shielding per military security standard, SCIF (sensitive compartmented information facility) contracting requirements.

The 700 MHz system used a Westell 700 MHz BDA with Battery Backup Unit (BBU).  This project involved performing a 20-grid test on each floor to ensure adequate signal was being delivered as designed.

We are tasked with ensuring acceptable signal is present on each of the 20 grids tested per floor to ensure first responder handheld radios will work inside the building when responding to an incident.  This is critical communication to aid in saving lives.

This building passed the inspection and is ready for occupancy.

We came to site and performed a 20 section grid test throughout the entire building testing for (SINR) Signal to interference plus noise ratio, (DAQ) digital audio quality and (BER) Bit error rate.

This building was able to pass where the customer turned our report into the fire department probably saving this customer $60-$75k on designing and installing a ERCES system.

Many times some contractors test a system only to “say” it failed to earn more money on the installation portion of the project.  The customer paid roughly $2,500 for this test that saved them quite a bit.

We like to earn the customers trust in them knowing the true results of their building.  We showed them our testing equipment and the readings at the site so they knew how the test was going to be transparent.

This customer was very appreciative.

It is important to test your building annually not only to comply with the fire code requirements but also to know if your building is still able to receive radio signals to all areas inside the building.

Many times in congested areas another building gets built and degraded the signal the existing building was receiving causing them to fail on their annual inspection.  When dealing with life safety it is vital to only state the facts and true signal readings at the site to ensure that when a critical event occurs that first responders are able to communicate inside your building and save lives!
