Viking Electronics SP422-E1600ATP2 E-1600A-TP2 EWP Special Faceplate Package
Overview
The SP422-E1600ATP2 is a packaged configuration of the Viking E-1600A-TP2 red emergency phone with EWP (Extreme Weather Protection) treatment and a special faceplate — supplied without an adapter. This SKU targets installers who need a telephone-line-powered emergency handset in harsh or wet environments where standard IP-rated housings fall short. The unit ships ready for surface or recess mounting, with gel-filled butt connectors included for weatherproof field terminations. At 5.25″ × 4.0″ × 2.0″ and 2.5 lbs shipping weight, it fits standard single-gang and custom rough-in boxes common in stairwells, parking structures, and outdoor call stations. The steel body with red powder-coat finish makes it immediately visible in emergency scenarios without requiring supplemental signage in most code-compliant installs. Telephone-line power (no separate power supply or PoE infrastructure required) means the phone remains operational during power outages — a critical reliability factor for life-safety deployments on dedicated emergency lines.
Compatibility
Designed for the Viking Electronics E-1600A Series emergency phone platform. Pairs directly with the E-1600A-TP2 base unit; the SP422 designation indicates this specific faceplate and EWP package variant. Compatible with standard POTS/analog telephone lines and central-office loop-start signaling — no PBX feature programming required for basic emergency call operation. The EWP moisture seal makes this variant appropriate for outdoor emergency phone installations where the standard E-1600A housing would be exposed to condensation or direct water contact. Not compatible with VoIP-only systems unless an analog terminal adapter (ATA) is provisioned upstream; note this package ships without an adapter by design.
Installation Notes
Operating temperature range of -30°F to 170°F suits unheated parking decks, cold-climate exteriors, and high-heat mechanical rooms where standard electronics fail. EWP treatment raises humidity tolerance to 100% — versus 95% non-condensing on the base model — so seal integrity at the mounting surface matters: use the included gel-filled butt connectors for all field wire splices rather than standard wire nuts, which wick moisture. Mount to a standard electrical box (surface or recess) per local code; no special substrate required. Steel construction and red powder finish are factory-applied — no field finishing needed.
