The pager dispatches rescue workers to handle emergencies. To get it working again, the county was forced to spend $8,000 for a part the next day.
"The public was never in danger. We have workaround plans in place. The message would have gotten out," public-safety director Tom Sullivan said.
But county officials said they regarded that failure as a harbinger of problems to come. In December 2010, Motorola announced it would stop supplying parts and maintenance for systems that date to the mid-1990s.
"We don't want to scare anybody, but we do have a failing system," Maza said.
The commissioners can build on the existing dispatch system with a bare-bones upgrade worth $18 million, or buy a new system for $72 million. Right now, they know too little to choose.
A consultant hired for $27,000 wrote a report, but the commissioners found it too technical.
"He didn't work out," Commissioner Joseph M. Hoeffel III said.
On Wednesday, the commissioners hired another consultant. The cost will be $100,000 to $200,000.
"I am totally on board with hiring another consultant," Commissioner Bruce L. Castor Jr. said. "If we take four weeks or six weeks or eight weeks to pick the right person, we ought to take the time and . . . get it right."
Challenged by a reporter that the board was dragging its feet to shift the burden of deciding onto the two commissioners chosen in the Nov. 8 election, Chairman James R. Matthews disagreed.
"That's not my style," he said. "I'd pick a vendor today, but the public insists on transparency. I am frustrated it is taking this long, but we want to make sure we make the right decision."
