Committee Statement and Meeting Notes

CommitteeStatement:

The original 27.5.3 did not adequately provide requirements for those circumstances where themunicipality or government agency has located the Communications Center at a location remote from theAlarm Processing Equipment for the public emergency alarm reporting system. This circumstance mightoccur when the municipality or government agency has moved the Communications Center to combineits service with other emergency dispatching, such as police and emergency medical services, or hasdecided to combine with neighboring towns or cities (regionalization). In such a case, it may beimpractical to completely relocate the alarm processing equipment. This FR also adds A.7.5.3 - see

A.27.5.3

Subsection 27.5.3 provides requirements for circumstances in which a municipality or government

agency has situated a communications center at a location remote from the alarm processing

equipment for the public emergency alarm reporting system. This might occur when the municipality or

government agency has moved the communications center to combine services with other emergency

dispatching, such as police emergency and medical services, or to combine with neighboring towns or

cities (regionalization). In such cases, it might be impractical to relocate the alarm processing

equipment.
