Emergency Communications Systems (ECS)
Area of Refuge/Rescue (AOR)
Used to provide 2-way communication between the building exterior and one or more designated areas offering relative protection from hazards (mainly fire) in an emergency.
An AOR system usually also includes illuminated directional signage.
Important
Despite their similarities in purpose, AOR is not a fire alarm system nor a component of one. When requesting low voltage quotes, it is necessary to specifically list AOR, else contractors may assume it is by others.
Area of Refuge is defined in nfpa-101_life-safety-code.
Two-Way Communication Systems
In NFPA 101 "two-way communication system" is used as generic term, to be installed in accordance with the governing code nfpa-72_national-fire-alarm-code.
nfpa-72_national-fire-alarm-code#Chapter 24 Emergency Communications Systems (ECS)
Emergency Responder Radio Communication Systems (ERRCS)
[!info] Also Known As
- Emergency Responder Radio Coverage (ERRC)
Relevant Standard: NFPA 1225
Where required, compliance is achieved by means of BDA and DAS systems as required by the AHJ.
[!quote] An Emergency Responder Radio Coverage (ERRC) system is a Public Safety Radio (PSR) DAS system that enhances the coverage of wireless signals in buildings. This allows first responders to communicate more effectively during emergencies.
