Viking Touch Free VoIP Entry Phone Surface Mount - E-20TF-IP

Viking Electronics E-20TF-IP Touch-Free VoIP Entry Phone

The Viking Electronics E-20TF-IP is a surface-mount SIP entry phone built for access points where hands-free operation matters — loading docks, cleanrooms, food-processing facilities, and any controlled-entry environment where occupants can't or won't touch a call button. Motion triggers the call instead of a physical press, eliminating contact entirely while delivering full two-way audio over your IP network.

Overview

The E-20TF-IP rides your existing SIP 2.0 (RFC 3261) infrastructure, draws power directly from a standard 802.3af PoE switch at under 4 watts, and provides a 2-amp relay for direct door strike or gate control — no separate controller required for single-door applications. Viking Device Manager software handles parallel programming, firmware updates, and polling across multiple units from a single workstation, making multi-door deployments far less labor-intensive than unit-by-unit configuration.

Key Features

• Touch-Free Motion Sensor: Adjustable detection range of one to four inches initiates a call the moment someone steps up to the door — no button press, no surface contact. In hygiene-sensitive environments (medical facilities, commercial kitchens, pharmaceutical labs), this eliminates a touch point entirely and reduces liability around shared surfaces.
• PoE Class 1 Power (<4W): Draws less than 4 watts via IEEE 802.3af — the lowest PoE class. This means virtually any managed or unmanaged PoE switch can power it without stressing the port budget, and no electrician is required for power at the door. A single Cat5e or Cat6 run handles both power and data.
• SIP 2.0 / RFC 3261 Compliant: Registers as a standard SIP endpoint on any compliant PBX or IP phone system — 3CX, FreePBX, Cisco UCM, Avaya, and hosted VoIP platforms. No proprietary gateway hardware needed. If your facility already runs a SIP system, the E-20TF-IP integrates without additional licensing or middleware.
• 2-Amp Relay Contacts: The on-board relay handles up to 2 amps, sufficient for most electric door strikes, magnetic locks, and gate controllers. Call the front desk, the guard station, or a SIP mobile app — whoever answers can trigger the relay remotely to release the door without leaving their desk or pulling out a separate access credential.
• Wideband Audio (G.722): Supports G.711u, G.711a, and G.722 codecs. G.722 delivers HD-quality voice — material in noisy industrial environments where narrow-band audio degrades intelligibility. Combine with the 90 dB SPL speaker output at 1 meter, and the unit is clearly audible in loud mechanical or HVAC-heavy spaces.
• Up to 5 Programmable Numbers: Store up to five destination numbers for failover routing — primary desk, backup extension, mobile, guard station, or alarm company. If the first number is busy or unanswered, the unit can roll to the next. Useful in facilities running lean staffing across shifts.
• Wide Operating Temperature Range (-40°F to 140°F): Certified for both extreme cold and desert-heat environments without enclosure heaters or coolers. This is a genuine outdoor-rated spec — relevant for northern climate loading docks, unheated stairwells, or rooftop mechanical room access points where entry phones regularly fail in winter.
• 100BASE-Tx Network Connection via RJ45: Standard RJ45 jack with 10/100 Base-T Ethernet. The three gel-filled butt connectors included in the wiring kit allow in-line splices without stripping insulation — a meaningful time-saver on installations where you're mid-run on existing cable rather than pulling a clean home-run.

Integration & Compatibility

The E-20TF-IP connects to any SIP 2.0 compliant phone system as a standard endpoint. This covers on-premises PBX platforms, hosted UCaaS providers, and SIP trunking services — provided your provider supports RFC 3261 direct SIP registration. The unit operates on a VoIP entry phone architecture rather than a proprietary protocol, which means it fits within existing dial plan structures without custom integration work.

For multi-door or campus-wide deployments, Viking's Device Manager software supports parallel configuration and firmware management across the E-20TF-IP and related Viking Electronics entry devices, reducing per-unit commissioning time significantly. Door control integration is handled directly through the 2-amp relay — pair this with a compatible electric door strike or gate controller and the relay handles release on call answer. For facilities needing a full access control workflow with credential management and audit logging, pair with a dedicated access control platform using the relay as a momentary trigger from the panel rather than from the phone.

Regulatory compliance covers FCC Part 15, Canada ICES-3 Class A, and CE — the unit ships ready for US, Canadian, and European deployments. Humidity tolerance is rated 5% to 95% non-condensing for standard installations; the EWP (Enhanced Weather Protection) variant of the product line tolerates up to 100% humidity for fully exposed outdoor use — confirm which suffix your order carries if moisture ingress is a concern for the specific install location.

Frequently Asked Questions

Q: Does the E-20TF-IP require a proprietary phone system, or does it work with any SIP PBX?

A: It works with any SIP 2.0 RFC 3261 compliant system — on-premises PBX, hosted UCaaS, or SIP trunking. No proprietary gateway or middleware is required.

Q: What PoE standard does the E-20TF-IP require?

A: The E-20TF-IP is IEEE 802.3af PoE Class 1, drawing under 4 watts. Standard 802.3af PoE switches and injectors are compatible — no 802.3at (PoE+) required.

Q: Can the E-20TF-IP control a door strike or electric lock directly?

A: Yes. The unit includes a 2-amp relay that can directly trigger most electric door strikes, magnetic locks, or gate controllers. The party answering the call activates the relay remotely to release the door.

Q: How many destination numbers can be programmed on the E-20TF-IP?

A: Up to 5 programmable numbers, allowing failover routing across multiple extensions or devices if the primary number is unavailable.

Q: What is the touch-free sensor range on the E-20TF-IP?

A: The motion sensor range is adjustable from one to four inches, letting you tune it to avoid false triggers from passersby while reliably detecting an approaching visitor.

Q: Is the E-20TF-IP suitable for outdoor installation in cold climates?

A: The operating temperature range is -40°F to 140°F (-40°C to 60°C), making it suitable for extreme cold environments such as outdoor loading docks or unheated entryways without supplemental heating.

James Everett

The E-20TF-IP (often searched as E 20TF IP) is the unit I reach for when a client asks for contactless entry at a controlled door and already runs a SIP phone system. The adjustable 1-to-4-inch motion sensor range is the detail that separates a clean install from a nuisance one — set too wide and you're generating calls every time someone walks past; dialed back to 1 inch and it only fires when someone steps directly up to the intercom plate.

Technical Highlights:

• Sub-4W PoE Class 1 Power: Under 4 watts means this device consumes roughly the same power as an idle IP phone. On a 24-port 802.3af switch with a 150W budget, you can power 37+ of these units before hitting the ceiling — relevant on campus-scale deployments.
• G.722 Wideband Audio: HD voice codec paired with a 90 dB SPL speaker at 1 meter. In a loading dock environment with active forklifts and HVAC, narrow-band audio at a door intercom is the single biggest usability complaint I hear. G.722 addresses that without any infrastructure change beyond codec negotiation at the PBX.
• 2-Amp Relay: Handles direct door strike or gate control without a separate access panel. For single-door deployments where you want attended remote release — guard station answers, clicks relay, door opens — this is sufficient and keeps the BOM tight. Multi-door or credential-based access still wants a dedicated panel; use the relay as a trigger input there.

Deployment Considerations:

• Viking Device Manager supports parallel programming across units — commission the SIP credentials, relay behavior, and destination numbers for a batch of E-20TF-IP devices from a single workstation session rather than touching each unit individually at the door. Plan for this in your pre-install workflow.
• The standard humidity rating is 5–95% non-condensing. If the installation point is directly exposed to rain, weather-driven condensation, or wash-down environments, confirm you're ordering the EWP variant rated to 100% humidity — the surface-mount E-20TF-IP as specified here is the standard humidity unit.

This unit fits best in healthcare corridors, pharmaceutical manufacturing entry points, and food-service back-of-house access where contact-free operation is a compliance or hygiene requirement and SIP infrastructure is already in place — not a general-purpose outdoor bullet-proof intercom, but exactly right for controlled indoor and protected-outdoor SIP deployments.
