Delivered Audio Quality (DAQ). A measure of audio quality over a transmission medium as defined in standards published in TIA/TSB-88C. The following table shows the DAQ descriptions as published in the document:

Delivered
Audio
Quality
(DAQ) 
Faded Subjective Performance Description
1 Unusable, speech present but unreadable.
2 Understandable with considerable effort. Frequent repetition due to noise/distortion.
3 Speech understandable with slight effort. Occasional repetition required due to noise/distortion.
3.4 Speech understandable with repetition only rarely required. Some noise/distortion.
4 Speech easily understood. Occasional noise/distortion.
4.5 Speech easily understood. Infrequent noise/distortion.
5 Speech easily understood.

Dedicated Radio Console (DRC). A fixed location console that contains at least the following components: 
  1. A handset or headset to broadcast and/or receive voice communications from/to ARCS.
  2. A visual display to identify all signals transmitted from the Firefighter handheld units and supervisory signals.
  3. Fire Department city wide standard key (#2642) to enable/disable radio transmission.
In-Building Auxiliary Radio Communication System (ARCS). Wireless two-way radio communication enhancement system installed in buildings to propagate Fire Department wireless frequencies for the use of the Fire Department in case of an emergency.

Repeater Channel System. A repeater system utilizing channels with paired receive and transmit frequencies. When a user within the building transmits on a repeater channel, the repeater system rebroadcasts the users' signal to the DRC and all users within the building on that channel. This transmission increases the distance from which users can directly talk with each other. A user at the DRC must enable repeater channel for users to communicate.

Simplex Channel System. A simplex system utilizing channels with the same frequencies for transmit and receive. Users communicate on simplex channels radio-to-radio without going through infrastructure. However, their radios need to be within a certain distance to be picked up by one another. A simplex system allows a user at the DRC to communicate with a user on a simplex channel anywhere in the building, even though the distance between the DRC and the user would typically be prohibitive. A simplex system only extends the transmission's reach for the DRC. It does not improve coverage between individual user radios.

Add 24.9.2.1 to read as follows: "Critical Areas. Critical areas, such as the fire/emergency command center(s), the fire pump room(s), exit stairs, exit passageways, elevator lobbies, standpipe cabinets, sprinkler sectional valve locations, and other areas deemed critical by the authority having jurisdiction at the time of plan examination, shall be provided with 100 percent floor area radio coverage."
