The Arlington County Board yesterday agreed to consider a law that would make business and residents pay for false burglar alarms.

The proposal, which has angered local banks, would make business and others pay $25 for each false alarm to which police respond. County officials say that 98 per cent of all burglar alarms the department receives are false, triggered by faulty alarm systems or careless employes.

Under the proposed Arlington law, to be considered Sept. 23, the county's police chief would be empowered to disconnect any alarm from the department's alarm system after three or more false alarms in a six-month period. After that, the county would charge $500 to reconnect the alarm.

In letters to the board sever bankers opposed the disconnection clause, saying that the police department alarm board creates a deterrent to robbery. But the board put off debate on the issue until next month.

Since 1972 Charlottesville has had a similar law, according to a recent Virginia State Crime Commission report. False alarms in that city have been reduced from three a day to three a week, the report said. No other Nothern Virginia jurisdiction has a similar charge, Arlington officials said.
