Apartment Complex Gates
The Phoenix Fire Department requires automatic vehicle gates at residential and commercial properties to have a fire department key switch on both sides of the gate. This allows the emergency personnel to access the
property in the event of an emergency. In 2001 the Phoenix Fire Department implemented the requirement for residential property gates, like those found at apartment complexes, to have a preemption system installed. Preemption systems consist of two components. A detector, found on the gate attached to the control system, and an emitter located on the emergency vehicle. The light and pattern transmitted from the vehicle triggers the detector to open the gate as the vehicle approaches. The preemption system prevents emergency responders from having to stop to use the key switch thus providing quicker access in a emergency response event.
