Viking Electronics E-1600-40-IP-EWP VoIP ADA Emergency Phone with Enhanced Weather Protection
The Viking Electronics E-1600-40-IP-EWP is a surface-mount, handsfree VoIP emergency phone engineered for SIP-based infrastructures where environmental exposure, ADA compliance, and network simplicity all need to land in the same device. Rated IP66 with Enhanced Weather Protection (EWP) extending humidity tolerance to 100%, it covers outdoor lobbies, parking structures, stairwells, and any covered exterior installation where standard IP66 alone leaves moisture risk on the table. A single RJ45 connection handles both data and power via PoE Class 1 — no separate power circuit, no transformer, no conduit run for 120V.
Overview
Emergency phones live at the intersection of life safety, accessibility law, and IP network infrastructure. The E-1600-40-IP-EWP addresses all three without requiring a dedicated analog line or a separate power supply. It runs on SIP 2.0 (RFC 3261) over a standard 100BASE-Tx network drop, integrates into any SIP-compatible phone system or UCaaS platform, and draws under 4 watts — well inside the 802.3af PoE budget of any managed switch port. The 16-gauge steel enclosure with textured red powder coat is built to take physical abuse in high-traffic areas, and the ADA-compliant design ensures code coverage in applications where that matters for permitting and occupancy. For a deeper look at Viking's Viking Electronics emergency communication products, the full line covers a range of mounting and dialer configurations.
Key Features
- IP66 + Enhanced Weather Protection (EWP) to 100% Humidity: Standard IP66 blocks water jets and dust ingress. The EWP upgrade pushes humidity tolerance to 100% non-condensing — critical in covered parking garages, loading docks, and coastal environments where condensation cycles would compromise a standard-rated enclosure over time. If your installation sees regular saturation events, EWP is the version to specify.
- PoE Class 1 Power Draw (<4W): At under 4 watts, this phone draws less from your switch's power budget than almost any IP camera on the same closet. A 30W PoE switch port can theoretically support seven of these devices. No separate UPS branch, no 120V outlet near the mounting location — the network cable does everything. This matters on retrofit jobs where pulling new power is a cost driver.
- 95 dB SPL at 1 Meter: In a loud environment — a loading dock, a mechanical room, a covered parking structure — 95 dB SPL is the difference between a caller actually reaching emergency services and a missed call. At typical emergency phone distances (1–3 meters), that output level cuts through ambient noise without requiring the caller to press the unit against their ear.
- SIP 2.0 (RFC 3261) with G.711u, G.711a, and G.722 Codec Support: G.711 covers standard PSTN-quality voice. G.722 delivers wideband (HD) audio where your SIP platform supports it — noticeably cleaner voice intelligibility in noisy environments. Compatibility with RFC 3261 means this device registers on virtually any SIP PBX, hosted UCaaS system, or SIP gateway without proprietary configuration.
- Operating Range -40°F to 140°F (-40°C to 60°C): This is a genuine cold-climate specification. Most commercial VoIP devices are rated to 32°F or 14°F at best. The E-1600-40-IP-EWP operates through northern Minnesota winters and Phoenix summers on the same unit — relevant for multi-site enterprise deployments where you want a single SKU across climate zones.
- ADA and CE Compliant: ADA compliance is a hard requirement for emergency phones in public access areas under the Americans with Disabilities Act. CE compliance opens European deployment. If you're specifying for a university campus, hospital campus, or municipal parking authority, ADA compliance is a non-negotiable box on the permit checklist — confirmed here.
- Three Gel-Filled Butt Connectors + Single RJ45: The termination kit matters on real installs. Gel-filled butt connectors are weatherproof wire splices — appropriate for damp locations and outdoor conduit entries where standard crimp connectors would corrode. Combined with the single RJ45 for the network drop, the wiring requirements are minimal and the weatherproof termination is included.
- FCC Part 15, CE, and Canada ICES-003 Class A Regulatory Compliance: Tri-market regulatory clearance (US, EU, Canada) means this unit can be deployed on enterprise campuses with facilities in multiple jurisdictions without requalification. For a procurement team standardizing on a single emergency phone SKU across North American and European sites, this matters.
Integration and Compatibility
The E-1600-40-IP-EWP connects to any SIP-compatible VoIP phone system or hosted platform via a standard RJ45 10/100 port. It supports SIP 2.0 per RFC 3261, making it compatible with Cisco Unified Communications Manager, Asterisk/FreePBX, Avaya, Microsoft Teams Direct Routing gateways, and most hosted SIP trunking providers. Audio codec support (G.711u, G.711a, G.722) aligns with the default codec stacks of all major platforms — no forced transcoding. Network compliance with IEEE 802.3af means any 802.3af or 802.3at PoE switch supplies power without configuration. If you're deploying alongside PoE network switches, Class 1 power draw leaves headroom for co-located cameras or other devices on the same switch. For campus-wide emergency communication systems, this model's single-cable deployment simplifies both the initial install and ongoing maintenance compared to analog or hybrid solutions. The surface-mount-only form factor (5.0″ × 5.0″ × 2.25″) requires a flat, rigid backing — plan conduit entry from the rear or side for clean installations. Review your VoIP infrastructure planning to confirm SIP trunk capacity if deploying multiple units on a single extension group.
Frequently Asked Questions
Q: Does the E-1600-40-IP-EWP require a separate power supply?
A: No. The E-1600-40-IP-EWP is powered via PoE Class 1 (IEEE 802.3af) over the same RJ45 cable used for network connectivity. It draws under 4 watts, so any standard 802.3af-capable switch port provides sufficient power without a separate power supply or transformer.
Q: What is the difference between the standard IP66 rating and the Enhanced Weather Protection (EWP) version?
A: The standard IP66 rating protects against powerful water jets and complete dust ingress. The EWP variant extends humidity tolerance from 95% non-condensing (standard) to up to 100%, making it the correct choice for environments with condensation, saturation events, or sustained high-humidity exposure such as covered parking structures, car washes, or coastal installations.
Q: Is the E-1600-40-IP-EWP ADA compliant?
A: Yes. The E-1600-40-IP-EWP is ADA and CE compliant, as stated in the manufacturer's product documentation. It is designed for handsfree operation, which is a key ADA requirement for emergency phones in public access areas.
Q: What SIP platforms is the E-1600-40-IP-EWP compatible with?
A: The device supports SIP 2.0 per RFC 3261, which is the industry-standard protocol supported by virtually all SIP PBX platforms (Cisco CUCM, Asterisk, Avaya, etc.) and hosted UCaaS/SIP trunking providers. It supports G.711u, G.711a, and G.722 audio codecs.
Q: What is the operating temperature range for the E-1600-40-IP-EWP?
A: The unit is rated for operation from -40°F to 140°F (-40°C to 60°C), making it suitable for cold-climate outdoor installations as well as high-heat environments.
Q: Is the E-1600-40-IP-EWP surface mount only, or can it be flush mounted?
A: The E-1600-40-IP-EWP is surface mount only. The 5.0″ × 5.0″ × 2.25″ enclosure requires a flat, rigid mounting surface. Flush or in-wall mounting is not supported by this model.
The spec that stands out most on the E-1600-40-IP-EWP is the combined IP66 + EWP humidity rating — up to 100% humidity versus the standard model's 95% non-condensing cap. That gap is meaningless in a dry office corridor and critical in a parking garage or transit hub where the air is perpetually saturated. I've seen standard-rated emergency phones develop intermittent contact corrosion within 18 months in those environments; the EWP enclosure is the right call for anything that sees sustained moisture exposure.
Technical Highlights:
- PoE Class 1 (<4W): Sub-4W draw means this device consumes less switch power budget than a basic IP camera. On a 24-port 802.3af switch running security cameras and access control readers, adding emergency phones to the same switch closet adds negligible load — no power budget recalculation required in most designs.
- 95 dB SPL at 1 Meter: That output level is loud enough to cut through an active loading dock or a covered parking structure with traffic noise. At 3 meters — a realistic caller distance — you're still in the 85–87 dB range, above the threshold for speech intelligibility in high-ambient-noise environments.
- -40°F to 140°F Operating Range: This is one of the widest thermal envelopes in the class. A university campus in Minnesota and a petrochemical facility in Texas can standardize on this SKU without sourcing a separate cold-weather variant — meaningful for enterprise procurement teams managing multi-site deployments.
Deployment Considerations:
- Surface mount only — the 2.25″ depth of the 5.0″ × 5.0″ enclosure requires a flush backing surface and rear or side conduit entry planning. Factor this into your rough-in drawings; retrofitting conduit after the enclosure is mounted is a common field headache.
- The three gel-filled butt connectors included for field wiring are weatherproof, but they're not a substitute for proper conduit sealing at the entry point. In EWP-rated deployments where you're relying on 100% humidity tolerance, the conduit entry seal is the other half of the protection equation — don't overlook it.
This is the version to specify for university campus emergency call stations, hospital campus exterior pathways, and multi-level parking structures — anywhere a single RJ45 run can replace an analog line and the environment demands more than standard IP66 can deliver.
