Viking Electronics K-1900-W2-ASH Ash Hot-Line Wall Phone with Non-Volatile Memory
The Viking Electronics K-1900-W2-ASH is a single-line, telephone-line-powered hot-line wall phone designed for facilities that need a dedicated, always-ready emergency or direct-dial station — no separate power supply, no programming lost during an outage, and no dependency on network infrastructure. It draws power directly from the telephone line (minimum 20V DC at 18mA), making it a reliable choice for elevator lobbies, stairwells, parking structures, and any location where a discrete, wall-mounted emergency phone needs to work the moment it's picked up. The ash color finish (K-1900-W2-ASH, often searched as K 1900 W2 ASH) integrates cleanly into commercial interior environments without the visual urgency of red.
Key Features
- Telephone Line Powered (20V DC / 18mA minimum): No local AC power circuit required — the phone draws everything it needs from the POTS line. That eliminates an entire category of installation complexity in locations where conduit runs for power are cost-prohibitive, and it means the phone stays operational during a facility power failure as long as the CO or PBX line stays up.
- Non-Volatile Memory: Programmed speed dial numbers survive power interruptions without a backup battery. In a hot-line application — elevator emergency phone, parking lot call station, loading dock — losing a programmed destination number after a line glitch is not acceptable. Non-volatile memory closes that failure mode entirely.
- 1–32 Digit Programmable Speed Dial: Field programmable directly at the unit. A single number up to 32 digits covers virtually any PSTN, PBX extension, or long-distance string you need to reach, including pause-injected sequences for PBX access codes. No programming hardware or software required on-site.
- Touch Tone or Pulse Dialing: Supports both dialing modes, which matters when integrating with older PBX systems or analog loop-start lines that still require pulse. Normal dialing runs 120ms tones / 10 pps; fast dialing compresses to 50ms tones / 20 pps for systems that can handle it.
- Hearing Aid Compatible Amplified Handset with Rotary Volume Control: The handset meets hearing aid compatibility requirements — relevant for ADA compliance considerations in public-access emergency phone installations. The rotary volume control lets the installer or end user set a fixed level appropriate for the ambient noise environment.
