# 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|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 and Signaling Code]].
|
|
|
|
[[nfpa-72_national-fire-alarm-code#Chapter 24 Emergency Communications Systems (ECS)|Chapter 24 Emergency Communications Systems (ECS)]]

|
|
|
[[nfpa-72_national-fire-alarm-code#24.8 Two-Way, In-Building Wired Emergency Services Communications Systems.]]

## 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.

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.
