Local EAS Info Has Moved

San Diego broadcasters should now get local EAS information from the SBE Chapter 36 EAS page. The site contains EAS resource links and an RMT schedule.

Oscar Medina is retiring from the position of Local Emergency Committee Committee (LECC) Chair and Gary Stigall volunteered to take it, tackling the San Diego EAS plan 2022 revision.

Gary will work with the Vice-Chair of the California State Emergency Coordination Committee (SECC), Richard Rudman, to revise the 2013 San Diego County plan. That plan will be posted when complete.

The EAS broadcast information email distribution will continue from the same MailChimp source, using the same subscriber list. No need to re-apply

It was in August 1999 that local EAS LECC Chair Jeff Williams left for Santa Barbara and passed the position to Oscar Medina, who at that time was Chief Engineer at KNSD (TV). Oscar has maintained a website and helped revise the local EAS plan. 

Bill Thompson, broadcast engineer at iHeart Radio San Diego, continues as LECC Vice-Chair.

Digital Alert Systems Issues New FEMA IPAWS CA File to Replace Expiring Certificate

DASDEC and One-Net Users Must Update Certificate Before Aug. 21 to Maintain Proper Operation

LYNDONVILLE, N.Y. — July 20, 2021 — Digital Alert Systems, the global leader in emergency communications solutions for video services providers, today announced the availability of an important update of Federal Emergency Management Agency (FEMA) digital certificates used to authenticate messaging from the Integrated Public Alert and Warning System (IPAWS).

The company has released updated IPAWS Certificate Authority (CA) credentials for the DASDECTM and One-NetTM series of Emergency Alert System/Common Alerting Protocol (EAS/CAP) encoder/decoders to replace a certificate in the current certification chain that will expire on Aug. 21. All U.S. DASDEC and One-Net users are advised to replace the soon-to-expire certificate to ensure the required message authentication continues to operate properly. Digital Alert Systems reminds all EAS participants the FCC requires them to “configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature.”

“With just a few weeks to go, we urge DASDEC and One-Net customers to update their certificate files before Aug. 21 to prevent any disruptions,” said Adam Jones, senior sales engineer for Digital Alert Systems. “While this seems like an annual occurrence, our customers will be pleased to know this new certificate is good until April of 2024!”

Digital certificates, called CAs, are used by FEMA to create a chain of trust between an EAS device and the IPAWS servers. The DASDEC and One-Net EAS/CAP devices use these special digital certificates to validate the authenticity of IPAWS-sourced CAP alerts. These certificates are designed to expire on a specific date and time, requiring the issuing authority to publish new certificates as replacements.

All DASDEC and One-Net customers using the IPAWS system must have the latest certificates in place so only messages authenticated through IPAWS are processed. IPAWS users who do not update their equipment before Aug. 21 could see this error message: “Event Log: Digital Signature

VERIFICATION ERROR: Signer UNTRUSTED! Check for correct CAP decoder CA file.” Alternatively, the device might simply ignore valid IPAWS alerts.

The new field service bulletin and CA file are now available from the Digital Alert Systems website at www.digitalalertsystems.com/DAS_pages/resources_fsb.html. DASDEC and One-Net customers should go to the website, download the field service bulletin for instructions, and link to the new CA file.

Sage ENDEC Offers Firmware Update

Sage Alerting Systems has announced that the Sage Digital ENDEC model 3644 users should concern themselves with two upcoming events:

FEMA Signing Certificate updates (CR-Rev6)

A signing certificate used by FEMA to validate CAP alerts will expire on Aug 21, 2021 at 21:00:00 UTC. Sage has released a free firmware update for Rev95 that you must install to permit your ENDEC to continue to receive EAS CAP alerts from FEMA after that date. You can install the CR-Rev6 update at any time before August 21, 2021. You do not need to install it before the National Periodic Test as the NPT will not use CAP this year.
Please go to the Sage firmware update page at https://www.sagealertingsystems.com/support-firmware-new.htm to read the release notes and download the update file. You must already be running the Rev95 release to install this update.

National Periodic Test (NPT)

This year’s test will be sent via the Primary Entry Point (PEP) network, that is, via over-the-air audio-EAS only, on August 11, 2021 at 2:20p.m. EDT. CAP will not be used. To help ensure that you will receive and relay this test, take the following steps:

1) Check your log to make sure that you are receiving weekly tests from your monitor assignments, and that you have been originating weekly tests and relaying Monthly Tests as required by your license type.

2) Make sure your ENDEC has a filter to receive and relay the NPT. The easiest way to check this is to access your ENDEC with a web browser. From the main page, click the Tools button on the left column, then click the “Verify Req” button. If you see “Your ENDEC will meet the FCC requirements for the National Periodic Test” on the last line, your ENDEC is ready.

If you have any questions regarding this update or the NPT, please email us at support@… or call 914-872-4069 and press 1 for support. If you get voice mail, please leave a message and we will call you back.
