Viking Electronics E-1600-22-IPEWP VoIP ADA Emergency Phone with Enhanced Weather Protection

The Viking Electronics E-1600-22-IPEWP is a two-button, hands-free SIP VoIP emergency phone engineered for demanding outdoor and semi-outdoor installations where ADA compliance, extreme weather durability, and reliable one-touch emergency communication are non-negotiable. Rated IP66 and tested across a -40°F to 140°F operating range, this stainless steel unit deploys via a standard double gang flush mount or — with the optional VE-5x5 enclosure — as a surface mount with enhanced weather protection (EWP) that extends humidity tolerance to 100%. It draws less than 4 watts over standard 802.3af PoE, eliminating the need for a local power supply and simplifying wiring to a single CAT cable.

Overview

Designed for SIP 2.0 (RFC 3261) environments, the E-1600-22-IPEWP integrates directly into any standards-compliant IP phone system without proprietary gateways or adapters. The unit supports HD voice via G.722 alongside G.711u and G.711a for compatibility with legacy SIP infrastructure. With a maximum sound output of 95 dB SPL at 1 meter and a built-in voice announcer, this phone is practical in noisy environments like parking structures, loading docks, stairwells, and building perimeters — anywhere voice intelligibility is critical but wiring conduit is limited.

Key Features

• IP66 Ingress Protection with EWP Option: IP66 means the unit withstands sustained water jets and complete dust ingress — appropriate for covered outdoor installations. Pair it with the optional VE-5x5 surface mount enclosure to achieve EWP status, which pushes humidity tolerance to 100% for exposed outdoor environments like parking decks and exterior wall installations where condensation and rain are constant factors.
• PoE Class 1 Power (<4W): Under 4 watts means this phone imposes almost no load on your PoE switch budget. A 30W 802.3af port can support multiple devices; the E-1600-22-IPEWP won't compete with cameras or access control readers for power headroom. No separate power supply, no AC outlet needed — one CAT cable handles power and data.
• -40°F to 140°F Operating Range: Verified performance across this range means cold-climate installations — unheated parking garages, exterior walls in northern climates — won't generate nuisance failures in winter. The 140°F ceiling also covers sun-exposed metal enclosures in summer without thermal shutdown risk.
• 95 dB SPL Voice Output at 1 Meter: That's roughly the volume of a loud shout at close range. In ambient-noise environments — loading docks, mechanical rooms, exterior locations near HVAC equipment — this output level ensures the far-end party is heard without the caller pressing their ear to the unit. Pair this with the built-in voice announcer to confirm call connection audibly.
• SIP 2.0 / RFC 3261 Native: No proprietary protocols, no analog adapters. The E-1600-22-IPEWP registers directly on any RFC 3261-compliant SIP server or UCaaS platform. This keeps the install within your existing IP telephony infrastructure and avoids the cost and failure point of an ATA.
• G.722 HD Audio Codec Support: G.722 wideband audio delivers noticeably clearer voice compared to narrowband G.711 — a real advantage in an emergency scenario where call clarity affects response quality. G.711u and G.711a are also supported for legacy SIP trunk compatibility.
• Dual Relay Contacts (2 Amp): Onboard relay outputs let you trigger a door strike, strobe, or alarm panel contact when a call is initiated. This closes the loop between an emergency phone activation and a physical access or alerting response without requiring a separate control module.
• ADA Compliant Design: ADA compliance is a hard requirement in most commercial and institutional new construction projects. This unit ships ADA-compliant out of the box, removing the need for third-party hardware modifications that typically void field compliance documentation.
• RJ45 10/100 Base-T with Gel-Filled Butt Connectors: The single RJ45 port handles both data and PoE. Three included gel-filled butt connectors support field splices in conduit runs where a direct RJ45 termination isn't practical — useful when pulling new cable through existing conduit to an exterior box.
• CE, FCC Part 15, and Canada ICES-003 Class A Certifications: Multi-jurisdiction regulatory compliance covers North American and European deployments from a single SKU, reducing procurement complexity for multi-site projects spanning the US, Canada, and international facilities.

Integration & Compatibility

The E-1600-22-IPEWP communicates over 100BASE-Tx Ethernet and registers as a standard SIP 2.0 endpoint — compatible with Cisco Unified Communications Manager, Asterisk/FreePBX, Avaya, Microsoft Teams Direct Routing (with a SIP gateway), and any platform supporting RFC 3261. The unit's dual relay contacts integrate with access control panels and alarm inputs without additional relay modules. For VoIP phone infrastructure planning, confirm your SIP server supports RFC 3261 and that your PoE switch provides 802.3af Class 1 — this unit won't require PoE+ budget. Review your PoE switch port allocation when deploying multiple emergency phones across a site; at under 4W each, budget impact is minimal. Surface mount installations require the separately sourced VE-5x5 enclosure; flush mount installations use a standard double gang electrical box. See Viking's broader emergency communication line for additional call station configurations including single-button variants and models with different housing profiles. Consult a VoIP emergency phone planning guide to map call routing, relay logic, and SIP trunk capacity before specifying quantities across a multi-building deployment.

Frequently Asked Questions

Q: What is the difference between the standard E-1600-22-IP and the E-1600-22-IPEWP?

A: The E-1600-22-IPEWP adds Enhanced Weather Protection (EWP), which extends humidity tolerance to 100% (versus the standard 5–95% non-condensing). The EWP variant is designed for use with the optional VE-5x5 surface mount enclosure in exposed outdoor locations. Both models share the same IP66 rating, SIP feature set, and operating temperature range.

Q: Does the E-1600-22-IPEWP require a separate power supply?

A: No. The unit is powered entirely via PoE (IEEE 802.3af, Class 1, under 4 watts). A standard 802.3af-capable switch or midspan injector is all that's required — no local AC power outlet needed.

Q: Is the E-1600-22-IPEWP ADA compliant?

A: Yes. The unit is designed and documented as ADA compliant, which is a common requirement for emergency phones in commercial, institutional, and public-access installations.

Q: What SIP platforms is the E-1600-22-IPEWP compatible with?

A: The phone supports SIP 2.0 (RFC 3261) and registers as a standard SIP endpoint. It is compatible with any RFC 3261-compliant SIP server or UCaaS platform, including Cisco CUCM, Asterisk/FreePBX, Avaya, and others. No proprietary gateway is required.

Q: Can the E-1600-22-IPEWP trigger a door strike or external alarm?

A: Yes. The unit includes dual relay contacts rated at 2 amps, which can be wired to door strikes, strobes, alarm panel inputs, or other low-voltage control devices to trigger a physical response when a call is initiated.

Q: What mounting options are available for the E-1600-22-IPEWP?

A: The unit supports flush mount installation in a standard double gang electrical box. Surface mount is also supported using the optional VE-5x5 enclosure, which also provides the Enhanced Weather Protection rating for exposed outdoor use.

The spec I keep coming back to on the E-1600-22-IPEWP is the -40°F floor on the operating temperature range. Most VoIP endpoints aren't rated below 32°F — this one is tested to -40°F, which is what you need when you're mounting emergency phones on exterior walls or in unheated parking structures in cold-weather regions. Combined with IP66 ingress protection and the EWP option pushing humidity tolerance to 100%, this unit handles outdoor environments that would degrade lesser hardware within a season.

Technical Highlights:

• PoE Class 1 (<4W): At under 4 watts, this is one of the lightest loads you'll put on a PoE switch. Relevant on sites where you're also powering cameras, access readers, and WAPs from the same switch — the E-1600-22-IPEWP doesn't compete for power headroom.
• 95 dB SPL at 1 Meter: That output level is loud enough to be heard over ambient HVAC noise or loading dock activity. Combined with the voice announcer confirming call connection, users in high-noise environments get both audible confirmation and volume that reaches the far end clearly.
• Dual 2-Amp Relay Contacts: These are often overlooked in spec comparisons. Being able to wire the call initiation directly to a door strike or alarm panel input means you get an integrated response loop without adding a relay module — cleaner wiring, one fewer failure point.

Deployment Considerations:

• The EWP rating requires the optional VE-5x5 surface mount enclosure — it's not inherent to the phone alone. If you're specifying for exposed outdoor locations, confirm the VE-5x5 is included in the BOM before submittal.
• The unit connects via a single RJ45 (10/100 Base-T). Three gel-filled butt connectors are included for field splicing, but plan your conduit pull lengths carefully — you can't extend PoE beyond 100 meters total from switch to device without a midspan or switch relocation.

This unit is the right call for university campus emergency call station projects, hospital parking structures, and transit facility platforms — anywhere ADA compliance is mandated, outdoor conditions are harsh, and the install crew is running a single-cable PoE infrastructure rather than AC power drops.
