Viking Electronics K-2000-DVA Eight-Input Voice Dialer and Digital Announcer
The Viking Electronics K-2000-DVA is a fully programmable multi-input auto dialer and digital announcer built for facilities where a single alarm trigger is not enough — think eight independent monitored zones, each capable of broadcasting a distinct recorded message and reaching up to eight stored phone numbers. Whether you're deploying it as a perimeter intrusion notifier, a store-cast paging system, or a critical-infrastructure alert relay, the K-2000-DVA handles the message routing without a dedicated monitoring subscription.
Overview
At its core, the Viking Electronics K-2000-DVA is an eight-channel voice dialer: eight discrete inputs, each with its own one-minute recording slot, totaling eight minutes of onboard message storage sampled at 64K — enough fidelity for clear speech announcements in a commercial environment. Each input can dial out to up to eight stored 32-digit phone numbers in sequence until the call is acknowledged. That combination makes it suitable for both emergency escalation (dial until someone picks up) and non-emergency broadcast (store-cast PA announcements triggered by schedule or sensor).
Compatible with access control and alarm integration workflows, the K-2000-DVA works alongside Viking's RC-2A and RC-3 remote DTMF controllers without conflict — a detail worth confirming before wiring if you're extending an existing Viking infrastructure.
Key Features
- Eight Independent Inputs with 1-Minute Messages Each: Each of the eight inputs stores a separate voice recording up to one minute long — so a door alarm, a temperature sensor, and a motion detector can each announce a contextually accurate message rather than a generic alert tone. Total onboard capacity is eight minutes at 64K sampling rate.
- Eight 32-Digit Phone Numbers Per Alarm: Each input can dial up to eight stored numbers sequentially. That 32-digit field accommodates extensions, pause codes, and international prefixes — useful in multi-site or PBX environments where a straight 10-digit number isn't enough.
- Programmable Qualifier Timer (1 Second to 18 Hours): The qualifier timer lets you filter nuisance triggers — a contact that must stay active for a set duration before the dialer fires. Configurable from one second to 18 hours, it prevents a brief door bounce from sending a midnight alert to your entire escalation list.
- Programmable Resume Timer (1 Second to 18 Hours): After an alarm event clears, the resume timer controls how long before the unit resets and arms again for the same input. This prevents rapid re-trigger loops on intermittent sensors.
- 80ms Input Detection Time: Inputs are scanned with an 80ms detection window — fast enough to catch brief contact closures reliably without requiring a long-hold activation signal.
- Dual Power Input — 120V AC or 12V DC: Accepts both 120V AC mains and 12V DC at 500mA. That dual-input flexibility means you can back it with a 12V battery or integrate it into an existing DC-powered panel without a separate AC adapter.
- Touch Tone Dialing with CPC Detection: Dialing uses 100ms on/50ms off DTMF timing with a 320ms minimum CPC (Call Progress Code) detection window — long enough to reliably detect call pickup on most PSTN and VoIP lines without false-positive acknowledgments.
- Operating Range 32°F to 90°F, 5–95% Non-Condensing Humidity: Rated for standard indoor commercial environments. Not designed for unheated exterior enclosures or high-condensation mechanical rooms — factor this in when choosing a mounting location.
Integration and Compatibility
The K-2000-DVA (often searched as K 2000 DVA) is designed for full compatibility with Viking's RC-2A and RC-3 remote DTMF controllers, allowing remote programming and control over standard phone lines. For broader alarm and notification infrastructure, its contact-closure inputs make it straightforward to wire into virtually any dry-contact output device — PIR sensors, door contacts, relay outputs from access control panels, or temperature switches. Pair it with a Viking intercom or entry system for a unified notification architecture on a single vendor platform. Review your phone line type (PSTN vs VoIP) against the 100ms/50ms DTMF timing and 320ms CPC window to confirm compatibility with your carrier before deployment.
Frequently Asked Questions
Q: How many phone numbers can the K-2000-DVA dial per alarm input?
A: Each of the eight inputs can store and sequentially dial up to eight phone numbers, each up to 32 digits long — accommodating extensions, pause codes, and international dialing strings.
Q: What is the total recording capacity of the K-2000-DVA?
A: Eight minutes total — one minute per input across all eight inputs — recorded and stored digitally at a 64K sampling rate.
Q: Can the K-2000-DVA run on battery backup?
A: Yes. It accepts both 120V AC and 12V DC at 500mA, so it can be powered from a 12V battery source or DC-backed panel during a mains outage.
Q: What is the warranty on the K-2000-DVA?
A: Viking Electronics provides a two-year limited manufacturer warranty on the K-2000-DVA.
Q: Does the K-2000-DVA work with Viking RC-2A and RC-3 controllers?
A: Yes. Viking explicitly documents full compatibility with the RC-2A and RC-3 remote DTMF controllers with no conflicts.
Q: What environments is the K-2000-DVA rated for?
A: It is rated for indoor commercial use: 32°F to 90°F operating temperature and 5% to 95% non-condensing humidity. It is not rated for outdoor or unheated enclosure installations.
The K-2000-DVA sits in a practical niche that full alarm panels often overlook: standalone multi-zone voice notification without a monitoring contract. The qualifier timer — adjustable from one second all the way to 18 hours — is the spec I point to first when integrators ask whether this unit will generate nuisance calls. Dial it in to match the sensor's expected dwell time and you eliminate most false-dispatch scenarios before they happen.
Technical Highlights:
- Dual Power Input (120V AC / 12V DC, 500mA): The 12V DC path is the one that matters in a real outage — pair this with a sealed lead-acid or Li-ion 12V backup and the dialer keeps firing even if mains power drops. No relay or converter needed.
- 32-Digit Phone Number Storage: Most competing dialers cap at 16 digits. The 32-digit field on each of the eight numbers per input handles PBX access codes, pause characters, and international country codes — critical in multi-tenant or enterprise PBX environments.
- 80ms Input Detection with 320ms CPC Window: The 80ms scan catches brief contact closures that slower dialers miss; the 320ms CPC detection prevents false acknowledgment on ringback tones, which is a common failure mode on VoIP trunks with non-standard call progress signaling.
Deployment Considerations:
- The RC-2A and RC-3 DTMF controller compatibility is documented explicitly — if you're extending an existing Viking installation, verify your controller model before assuming plug-and-play. Other third-party DTMF controllers may work but are not documented in the evidence.
- The 32°F to 90°F operating ceiling is a hard limit for indoor commercial spaces — do not install in an unheated exterior enclosure, a rooftop equipment cabinet, or a boiler room where ambient consistently exceeds 90°F.
This unit is the right specification for a mid-size retail chain, light industrial facility, or municipal utility site that needs eight independent monitored trigger zones, custom recorded voice messages per zone, and sequential escalation dialing — all without recurring monitoring fees.
