Code Blue CB4U00142 4-u Underground Help Point Tower
The CB4U00142 is a Code Blue 4-u Series underground help point tower in the Safety Blue/White colorway, built for campus, parking structure, and pathway emergency call stations where a hardwired, code-visible unit is required. It houses a speakerphone module behind a 0.125-inch steel enclosure and mounts to an underground junction box, keeping wiring concealed and out of reach at grade level.
Compatibility
CB4U00142 accepts Code Blue's IA4100 Analog full-duplex speakerphone as a standard feature, and is also listed compatible with the LS1000 VoIP Speakerphone and LS2000 VoIP Handset — so the same tower body supports either an analog phone line or a PoE-based VoIP deployment depending on which speakerphone module gets installed. Confirm which speakerphone ships with or is specified for your unit before wiring, since analog and VoIP modules have different backend requirements (phone line vs. network drop with PoE).
Installation Notes
At 70 lbs. and 26.05 in. H x 14 in. W x 12.78 in. D, this is a two-person, permanent installation over an underground conduit run — plan pad or footing work accordingly rather than a surface-mount job. The steel body is built to NEMA 4 for washdown- and weather-tight performance, so it holds up to direct rain, hose-down, and dust in outdoor pathway or garage locations. It's designed to ADA specifications, which matters for height and reach compliance on public-facing installs — verify your mounting height against your local accessibility code rather than assuming a default. Power input is 12-24V AC/DC; if the VoIP speakerphone option is used, PoE simplifies the run to a single Cat cable instead of separate power and data. The unit carries UL 62368-1 safety listing and includes an LED faceplate light for visibility and location marking at night. Warranty coverage is 1-year.
