Viking Electronics E-1600-02-IPEWP VoIP ADA Emergency Phone with Enhanced Weather Protection
Overview
The Viking Electronics E-1600-02-IPEWP is a SIP-based VoIP emergency phone built for outdoor and harsh-environment installations where standard weather ratings simply aren't enough. Engineered around an IP66 enclosure and Viking's Enhanced Weather Protection (EWP) specification — which pushes humidity tolerance to 100%, compared to 95% non-condensing on standard models — this unit is the correct answer for coastal facilities, covered parking structures, transit platforms, and industrial sites that cycle between wet and dry conditions. It ships as a flush-mount configuration in a 14-gauge 316 stainless steel housing, runs on standard 802.3af PoE (under 4 watts), and delivers ADA-compliant voice announcements without requiring a separate power circuit.
For integrators comparing it against the non-EWP variant: if the installation is indoors or in a controlled environment, the standard E-1600-02-IP saves cost. If the enclosure sees condensing humidity, rain intrusion, or extreme temperature swings, the E-1600-02-IPEWP is the right call — the EWP designation is not cosmetic.
Key Features
- Enhanced Weather Protection (IP66 + 100% Humidity): IP66 means no damage from direct water jets or wind-driven rain. The EWP designation adds 100% humidity tolerance — critical in covered garages, loading docks, and coastal environments where condensing moisture destroys standard electronics over time. Standard Viking IP phones are rated to 95% non-condensing; EWP units eliminate that ceiling.
- PoE Class 1 Power (<4W): Drawing under 4 watts, this phone qualifies as Class 1 on an 802.3af switch — the lowest power tier. In large emergency phone deployments across a campus or parking structure, that matters: a 24-port 802.3af switch budgeted at 370W can support far more Class 1 devices than Class 3 or higher units. No separate power supply, no conduit for AC — just a single Cat5e/6 run.
- SIP 2.0 / RFC 3261 Compliance: Native SIP means the E-1600-02-IPEWP registers directly to any standards-compliant IP PBX or hosted SIP platform. No proprietary gateway hardware required between the phone and the call manager — a real cost and complexity reduction in multi-site or cloud-hosted telephony environments.
- Audio Codecs G.711u, G.711a, G.722: G.722 wideband audio delivers noticeably better voice intelligibility than narrowband G.711 — relevant when someone is calling from a noisy loading dock or outdoor mechanical area. G.711u/a ensures compatibility with legacy SIP platforms that haven't implemented wideband.
- 95 dB SPL @ 1m Maximum Sound Pressure: 95 dB at one meter is loud enough to cut through moderate ambient noise — a forklift bay, a transit platform, a covered parking deck. For extremely loud industrial environments (above 85–90 dBA ambient), confirm the ambient level against this output before specifying.
- Operating Temperature -40°F to 140°F (-40°C to 60°C): This range covers essentially every North American outdoor installation, including northern climates that see sustained sub-zero winters and desert environments that hit 130°F+ in direct sun. Most competing units top out at -4°F or 32°F — the -40°F floor is a genuine differentiator for unheated enclosures.
- 14-Gauge 316 Stainless Steel Housing: 316 stainless (marine grade) resists chloride corrosion — the failure mode that takes out 304 stainless and painted steel in coastal, poolside, or chemical plant environments. If the installation is inland and not exposed to salt air, 316 is over-specified but not harmful.
- Built-in Dialer and Voice Announcer: The integrated dialer and ADA-compliant voice announcer mean no external controller board, no add-on modules. ADA compliance is required under Title II and Title III for public facilities — having it factory-integrated avoids field verification headaches.
- Relay Contacts (2 Amp): Two onboard relay contacts allow the phone to trigger a local device — a gate latch, a door strike, a strobe light — at the moment of a call or on command. Useful in parking or building entry scenarios where the emergency phone also needs to control access without a separate relay module.
- Connections: RJ-45 + Gel-Filled Butt Connectors: The single RJ-45 handles data and power (PoE). Three gel-filled butt connectors handle field wiring for relay or auxiliary connections — gel-filled is the right choice for outdoor junction points because it seals against moisture wicking.
Integration and Compatibility
The E-1600-02-IPEWP connects over 100BASE-Tx Ethernet and registers as a standard SIP 2.0 endpoint. It is compatible with any RFC 3261-compliant IP PBX, call manager, or hosted SIP trunk — including Cisco Unified Communications Manager, Avaya Aura, FreePBX/Asterisk, and major hosted platforms. Codec negotiation supports G.711u, G.711a, and G.722; confirm your call manager's wideband support if G.722 intelligibility is a design requirement. The phone draws under 4W, making it compatible with any 802.3af-capable switch or midspan injector — no 802.3at (PoE+) budget required. The two 2-amp relay contacts integrate with access control panels, door hardware, or alerting devices via the gel-filled butt connector terminations. Regulatory compliance includes FCC Part 15, Canada ICES-003 Class A, and CE — covering US, Canadian, and European deployments.
Frequently Asked Questions
Q: What is the difference between the E-1600-02-IPEWP and the standard E-1600-02-IP?
A: The EWP (Enhanced Weather Protection) variant is rated for humidity up to 100%, compared to 5–95% non-condensing on the standard model. Both carry IP66 ingress protection. Choose the E-1600-02-IPEWP for any installation where condensing moisture, coastal salt air, or wash-down environments are a factor.
Q: Does the E-1600-02-IPEWP require a PoE+ switch, or will standard PoE work?
A: Standard 802.3af PoE is sufficient. The phone draws under 4 watts (Class 1), so any 802.3af-capable switch or midspan injector will power it without needing 802.3at (PoE+) budget.
Q: Is the E-1600-02-IPEWP ADA compliant?
A: Yes. The unit includes a built-in voice announcer and dialer designed to meet ADA requirements. Confirm your specific jurisdiction's accessibility code for any installation-level compliance obligations.
Q: What SIP platforms is the E-1600-02-IPEWP compatible with?
A: It implements SIP 2.0 per RFC 3261, making it compatible with any standards-compliant IP PBX or hosted SIP platform. This includes Cisco Unified Communications Manager, Avaya, Asterisk/FreePBX, and major SIP trunk providers. No proprietary gateway is required.
Q: Can the E-1600-02-IPEWP trigger a door strike or gate relay?
A: Yes. The unit includes two onboard relay contacts rated at 2 amps, which can be wired to a door strike, gate, strobe, or similar device. Field connections use the included gel-filled butt connectors.
Q: What are the housing dimensions and weight?
A: The unit measures 13 inches x 10.5 inches x 2.0 inches (330mm x 267mm x 51mm) with a shipping weight of 7 lbs (3.18 kg). It is constructed from 14-gauge 316 stainless steel and is configured for flush mount installation.
The spec I keep coming back to on the E-1600-02-IPEWP is the 100% humidity rating — not IP66, which most outdoor phones hit, but the EWP designation that eliminates the condensing humidity ceiling entirely. That distinction matters more than it sounds on paper. I've seen standard IP66 phones fail inside two years on covered transit platforms and coastal parking structures because the enclosure seals out liquid water but can't handle repeated condensation cycles inside the housing. Viking's EWP addresses exactly that failure mode.
Technical Highlights:
- PoE Class 1 (<4W): Under 4 watts means this phone puts virtually no load on your switch power budget. On a 48-port 802.3af deployment serving a large campus, you can run a significantly higher density of these units per switch without upgrading hardware.
- -40°F to 140°F Operating Range: This is a genuine cold-climate spec. Most VoIP emergency phones bottom out at 32°F or 14°F — this unit handles unheated northern parking structures and exposed exterior columns without a heated enclosure surround.
- 316 Stainless + Gel-Filled Butt Connectors: 316 stainless is marine-grade chloride-resistant — not cosmetic. Paired with gel-filled butt connectors at the field terminations, the entire wetted assembly resists long-term corrosion at the connection points, not just at the face.
Deployment Considerations:
- The phone registers as a standard SIP 2.0 endpoint — provision it exactly like any SIP desk phone on your call manager. The G.722 wideband codec is supported, but confirm your PBX or hosted platform negotiates wideband before advertising that capability to end users.
- The 2-amp relay contacts handle light-duty loads (door strikes, strobes) but are not rated for high-current devices. If the installation requires triggering a heavy gate motor or a large solenoid, interpose a relay rated for that load — don't wire it direct.
This unit is the right specification for coastal university campuses, covered transit hubs, and waterfront industrial facilities where humidity, salt air, and temperature extremes disqualify standard-rated emergency phones. If the installation is a dry interior corridor or a climate-controlled lobby, the standard E-1600-02-IP covers the requirement at lower cost.
