- 24.10* Two-Way Emergency Communications Systems for Rescue Assistance:
- Editor's Note: For the 2022 edition of the Code, the title of this section has been revised to reflect the inclusive set of requirements covered within the section. As explained in A.24.10, types of two-way ECSs can vary but are generally members of the same system type and are often required by building and fire codes in many locations within a building. These systems are provided to allow building occupants to communicate with emergency personnel when they need assistance or rescue. These systems are grouped together because they are basically the same type of equipment that provides communications in a different location. Many of the requirements found in 24.10.1 through 24.10.14 are new for the 2022 edition and include requirements from UL 2525, Two-Way Emergency Communications Systems for Rescue Assistance.
- 24.10.1: Systems used for area of refuge emergency communications systems, stairway communications systems, elevator landing communications systems, and occupant evacuation elevator lobby communications systems shall be listed in accordance with applicable standards, such as UL 2525, Two-Way Emergency Communications Systems for Rescue Assistance.
- 24.10.2: Where required by the enforcing authority, governing laws, codes, or standards, any communications system specified in this section shall be installed in accordance with 24.10.2 through 24.10.14
- 24.10.3.1: When a remote call station(s) is activated by a building occupant(s), a two-way live voice communication shall be required to operate between the remote call station(s) and a constantly attended location.
- 24.10.3.2*: The master control station shall be installed in a central control point within the building.
- 24.10.3.3*: The constantly attended location shall be located either within the building or at a monitoring location and be approved by the authority having jurisdiction.
- 24.10.6*: If the central control point is not constantly attended, the system shall have a timed automatic communications capability to connect with an off-premises constantly attended monitoring location approved by the authority having jurisdiction, where trained personnel can initiate the appropriate response.
- 24.10.7*: In the event of an off-premises connection, a signal shall be transmitted to the off-premises monitoring location, identifying the specific building prior to initiating the live voice two-way communication.
- 24.10.8: Two-way emergency communications systems shall have the capability of transmitting a verbal signal to identify the specific building address to off-premises monitoring personnel before operators complete the connection to the remote call station.
- 24.10.9*: The physical locations of the remote call stations and the master control station shall be as designated by the building code in force and the system designer and approved by the authority having jurisdiction.
- 24.10.10: The specific location of each active remote call station shall be identified on the master control station display on a floor and area basis in accordance with 24.10.11.
- 24.10.11: Where all active calls are not simultaneously displayed, the master control stations shall provide the following:
- 1.) Previously answered calls shall be capable of being prioritized as urgent on the master control station to differentiate more urgent life safety related calls from less urgent calls.
- 2.) A minimum of 8 active call station identifiers shall be visible in the following order of priority:
- a) Previously unanswered calls, oldest first
- b) Previously answered calls, prioritized as urgent, oldest first
- c) Previously answered calls, not prioritized as urgent, oldest first
- 24.10.12: The remote call stations shall provide for hands-free, two-way communication and provide an audible and a visual signal to indicate communication has occurred.
