# Emergency Communications Systems (ECS)
## Area of Refuge/Rescue (AOR)
See also [[fire-alarm]].
Used to provide 2-way communication between the building exterior
## "Two-Way System"
With the exception of ERCCS,
it is not appropriate to refer to one or any of these as _the_ two-way system.
_A_ "two-way communication system" as used by the ICC codes
refers to a single connection (for lack/ignorance of a better term),
therefore any building will always have more than one.

For a high-rise condominium project,
To exclude _the_ two-way communication system
would be as nonsensical as excluding _the_ unit subfeed.

All systems currently listed in this note
are described as "two-way communication systems".
Those listed directly below have no overlap:
* stairway communication systems --- [[ibc_s0403#403.5.3.1 Stairway communication system.|IFC 403.5.3.1]]

* area of refuge communication systems --- [[ibc_s1009#1009.6.5 Two-way communication.|IFC 1009.6.5]]
* emergency responder communication coverage system -- [[ifc_s0510#SECTION 510---EMERGENCY RESPONDER RADIO COVERAGE|IFC Section 510]]

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.
