Coming Soon: The 'Holy Grail' of Central Station Communications

CSAA and APCO and industry vendors partner to develop new digital communications standard for alarm reporting


The standard may make some industry long-timers recollect a time in the 1990s when a similar system was attempted, but was being developed by just one provider. Many business owners reacted negatively to it, thinking it would be expensive and would only ensure that money was going to one pocket. The industry outcry – right or wrong – kept the project, which wasn't developed with public and private sector input, from ever growing legs, explains Doyle.

The implementation of this joint APCO, CSAA standard, however, will be quick in our industry, says Doyle, because the system was not designed to make money for any of the involved parties, but simply to solve a persistent problem in the industry.

"This is one of the things trade associations have to do these days – they have to bring the public and private sectors together," says Doyle. "And that's what we're doing here."

Still, says Pam Petrow, the executive vice president of Vector Security, and a key player in the creation and testing of the standardized interface, the industy shouldn't expect this software out by Christmas 2005, especially since most of the work is on a gratis basis, with software developers donating the time when they are able.

According to Petrow, her company has been involved with testing the interface with PSAPs for the City of Richmond and York County, Va., as well as with CAD vendors and General Electric's Monitoring Automation Systems software. The second part of the test that Vector Security is participating in will move to the software from DICE and MicroKey as well as PSAPs from California and Florida. And a third testing period is planned after that.

The challenge, says Petrow, is getting on board with all the PSAPs to interface with their CAD software.

"There are a lot of established [CAD] vendors, and then there are companies that are producing independent software designs, and then there are even in-house players, IT staff members who are creating software," says Petrow, explaining why the interface isn't an "instant gratification" project.

But if that was the only challenge, the project would have been a piece of cake. Petrow lists the following challenges as areas that the CSAA/APCO interface standard had to overcome, and she says the testing has been vital to this process:

  1. Terminology - The alarm industry uses many alarm event types interchangeably. During a discussion the operator could clarify if a panic was a silent or audible signal and possibly the type of emergency condition it signified. Electronically, we had to define what type of response we wanted for the various signal types - burglary, panic, emergency, duress, hold-up, etc.
  2. Which data elements to pass - All CAD systems are different with different fields available for recording data and these fields have varying lengths. We had to determine what information was critical to communicate and how that data would be passed: number of characters, if the characters could be alpha, numeric or alpha/numeric, if the field was mandatory or optional.
  3. Technology roadblocks - many CAD systems are self-written and the authors don't have the experience to write an interface for their products. We needed to spell out the exact requirements so consistent data could be exchanged from many different parties with different levels of IT sophistication.
  4. How does a PSAP know to accept data from an incoming source - There has to be a way to authenticate the sending party.
  5. Ability to accept or reject transmissions - Depending on the circumstance a PSAP may decide they are not accepting an alarm transmission (may be the wrong PD, wrong emergency agency police vs. fire vs. EMS, storms, etc) so a protocol for rejecting a transmission had to be established.
  6. IT security issues
  7. Street nomenclature - Different databases use different abbreviations and data entry protocols for addresses which could lead to rejections if not compatible.

Even with this heavy list of challenges that must be surmounted to create a shared standard, the rough spots in the technology are being smoothed over, and the process is moving forward.

"Our goal is to have testing done at the end of the year and then move on to the registration server [an online database of sorts that would be part of the authentication process and would tell station's which PSAPs are on board with the new standards, and tell PSAPs which stations are up to speed as well]," explains Petrow. "We hope to have the interface standard set up by mid to late 2006, but for now, we're just thrilled have it working."
