Viking Electronics K-19FDEA Custom Speed Dial Default Software for K-1900-3
Overview
The Viking Electronics K-19FDEA is a factory-installed custom software configuration for the Viking Electronics K-1900 Series telephone — specifically the K-1900-3 model. Its defining behavior: if no touch tones are entered within 6 seconds of going off-hook, the unit automatically defaults to and dials a programmed speed dial position. For entry phone and emergency hotline deployments where callers may hesitate or not know what to dial, this auto-default behavior eliminates the dead-air problem and ensures the call connects every time. The K-19FDEA (often searched as K 19FDEA) is not a standalone device — it is a software-defined variant of the K-1900-3 hardware platform, ordered as a unit with this behavior pre-programmed at the factory.
Key Features
- 6-Second Auto-Dial Default: If no DTMF tones are detected within 6 seconds of off-hook, the unit dials the configured speed dial number automatically. In entry phone or lobby intercom scenarios, this prevents abandoned calls from callers unfamiliar with the system.
- Telephone Line Powered (20V DC / 18mA minimum): No separate power supply or AC outlet needed. The unit draws power from the telephone line itself, simplifying installation in locations where running power is impractical — stairwells, parking structures, gate posts.
- 1–32 Digit Programmable Speed Dial: The auto-default destination supports up to 32 digits, accommodating extensions, outside lines with access codes, or long-distance numbers without truncation.
- Dual Dialing Speed — Normal (120ms / 10 pps) and Fast (50ms / 20 pps): Fast mode at 20 pulses per second cuts connection time noticeably on high-call-volume entry points. Match the dialing speed to your PBX or CO line requirements during commissioning.
- Hearing Aid Compatible Amplified Handset with Rotary Volume Control: ADA-relevant in public-access or commercial environments. The rotary control lets users adjust to their own hearing level without staff intervention.
- Available in Desk and Wall Mount Configurations: The desk unit measures 9.0″ × 8.25″ × 4.75″ with an RJ11 connection. The wall version flips the profile to 4.0″ × 4.75″ × 9.0″ with an RJ11W connector — same footprint, different orientation for surface or gang-box mounting on corridors and entry vestibules. Both ship at 3 lbs.
- Operating Range 0°C to 32°C (32°F to 90°F), 5–95% RH Non-Condensing: Rated for climate-controlled interior environments. Not suitable for unheated vestibules, outdoor enclosures, or locations subject to condensation — plan accordingly.
- Red or Ash Color Options: Red units are immediately visible in emergency or safety-critical locations. Ash blends into standard commercial interiors. Specify color at order time — factory-programmed units are not field-swappable.
Integration and Compatibility
The K-19FDEA connects to any standard analog telephone line or analog port on a PBX via RJ11 (desk) or RJ11W (wall). It requires a minimum 20V DC at 18mA from the line — verify your analog port or CO line meets this threshold before deploying in lower-voltage PBX environments. The speed dial destination is programmed at the factory; confirm the target extension or outside number before ordering. For broader emergency phone deployments, pair with a Viking-compatible analog port aggregator or door-control relay for full entry management.

Frequently Asked Questions
Q: What happens if a caller picks up the handset but doesn't press any keys?
A: The K-19FDEA automatically dials the pre-programmed speed dial number after 6 seconds of off-hook with no DTMF tones detected. The call connects without any caller action required.
Q: Is the speed dial number field-programmable or factory-set?
A: The K-19FDEA is a factory-installed custom software configuration. The speed dial destination should be confirmed and specified at the time of ordering. Consult Viking Electronics for programming change procedures if the target number needs to change post-delivery.
Q: Does the K-19FDEA require an external power supply?
A: No. The unit is telephone line powered, drawing a minimum of 20V DC at 18mA from the connected analog line. No AC outlet or separate power supply is required.
Q: Can this phone be used outdoors?
A: The K-19FDEA is rated for 0°C to 32°C (32°F to 90°F) operating temperature and 5–95% non-condensing humidity — indoor environments only. For outdoor or unheated locations, a different Viking model with an appropriate enclosure and extended temperature rating would be required.
Q: What is the warranty on the K-19FDEA?
A: Viking Electronics provides a two-year limited manufacturer warranty on the K-19FDEA.
Q: What mounting options are available?
A: The K-19FDEA is available in both desk (9.0″ × 8.25″ × 4.75″, RJ11) and wall-mount (4.0″ × 4.75″ × 9.0″, RJ11W) configurations. Specify the required mounting style and color (Red or Ash) at the time of order.
The K-19FDEA solves a specific and recurring problem in entry phone deployments: callers who pick up the handset and do nothing. The 6-second DTMF timeout means the unit auto-dials the programmed destination regardless of caller action — no abandoned calls, no security desk wondering why the phone rang and dropped. That behavioral guarantee, baked in at the factory, is what separates this variant from a standard K-1900-3.
Technical Highlights:
- Line Power (20V DC / 18mA min): Draws from the analog line — no power conduit run to the phone location. In concrete stairwells or mechanical rooms where pulling AC is a change-order, this is the spec that keeps the project on budget.
- Dual Dial Speed (Normal 120ms / Fast 50ms): Fast mode at 20 pps cuts post-pickup connection time meaningfully on high-traffic entry points. Set this during commissioning to match your PBX's DTMF acceptance window — mismatched timing is the most common cause of failed auto-dials on analog ports.
- 1–32 Digit Speed Dial Capacity: Handles trunk access codes, full 10-digit outside numbers, or internal extensions without truncation — relevant when the dispatch or security center number requires a prefix digit before the extension.
Deployment Considerations:
- The 0°C to 32°C (32°F to 90°F) operating range means this unit is strictly for climate-controlled interior locations. A vestibule that drops below freezing overnight disqualifies it — plan for a different Viking variant with a wider temperature envelope in those cases.
- The speed dial destination is factory-programmed. Confirm the exact target number — including trunk access code and area code if applicable — before submitting the order. A post-delivery reprogramming request adds lead time and cost.
The K-19FDEA is the right call for ADA-accessible interior emergency stations, lobby courtesy phones, and secured entry vestibules where the assumption that callers know what to dial cannot be made — healthcare facilities, assisted living, government lobbies, and multi-tenant commercial buildings with after-hours access control are the primary deployment fits.
