Egress
Exits
D1 + D5 — south wall
Max Occupancy
8 persons
Path
Rooms → D1 / D5 → corridor
Two exits on the south wall: D1 (STC 50, main entry serving Video/Podcast and VO Live) and D5 (STC 50, dedicated external exit from the Control Room, opens outward). Egress paths must remain clear at all times. No equipment, cables, or furniture may block the path from any of the 3 rooms to D1 or D5.
Fire Ratings for Acoustic Assemblies
| Assembly | Fire Rating | Notes |
|---|---|---|
| Float floor (18mm T&G plywood) | Requires intumescent treatment or fire-rated underlayment | Per local code |
| Gypsum partitions (12.5mm) | 30–45 min fire rating | Standard gypsum inherent rating |
| Green Glue partitions (double gypsum) | Verify Green Glue does not degrade rating | Use fire-rated Green Glue Compound (available) |
| Ceiling tiles — Rockfon Sonar E | Class A fire rated | VO / Control / Video/Podcast |
| Acoustic panels (fabric-wrapped rockwool) | Must use Class A fire-rated fabric | All rooms |
Fire Detection
| Device | Location | Qty | Notes |
|---|---|---|---|
| Smoke detector | Each room | 3 minimum | Connected to building fire alarm |
| Heat detector | Server room B313 (adjacent east wall) | 1 | Not part of zone but affects egress |
| Plenum detector | Above ceiling (if plenum is air return) | As required | Required if plenum serves as air return |
Emergency Lighting
| Requirement | Specification |
|---|---|
| Per-room | Minimum 1× emergency light per room on battery backup |
| Egress path | D1 exit must be illuminated during power failure |
| E-Light dual purpose | 3× E-Light 5W 4000K near D1/south wall serve ambient + emergency egress |
Cable Fire Ratings
| Location | Required Rating | Notes |
|---|---|---|
| Above-ceiling (plenum) | CMP (plenum-rated) | Already specified in electrical |
| In-wall audio cable | CM or CMR rated | Mogami W2534 meets CM |
