Viking Electronics E-1600-TP2IPEWP Two-Button VoIP Emergency Phone with Enhanced Weather Protection
Overview
The Viking Electronics E-1600-TP2IPEWP is a flush-mount, ADA-compliant, two-button VoIP emergency phone engineered for SIP-based phone systems in demanding outdoor and industrial environments. Built to integrate directly into Talk-A-Phone back boxes and rated IP66 with Enhanced Weather Protection (EWP) for humidity tolerance up to 100%, this unit is purpose-built for locations where standard VoIP endpoints simply won't survive — perimeter call stations, parking structures, campus emergency call points, and industrial facilities running 24/7 exposure to the elements. It draws under 4 watts via PoE Class 1, so it won't stress your switch budget, and its -40°F to 140°F operating range means it functions from Minnesota winters to Arizona summers without a heater or enclosure upgrade.
For integrators sourcing Viking Electronics emergency communication devices, the E-1600-TP2IPEWP sits at the intersection of rugged hardware and standard SIP interoperability — no proprietary gateways, no special licensing.
Key Features
- IP66 + Enhanced Weather Protection (EWP): IP66 blocks sustained water jets and dust ingress — adequate for most outdoor call stations. The EWP upgrade pushes humidity tolerance to 100% non-condensing, which matters in coastal installations, car washes, and covered loading docks where moisture vapor is constant rather than intermittent. Standard IP66 caps at 95% RH; EWP removes that ceiling.
- PoE Class 1 (<4W): Drawing under 4 watts, the E-1600-TP2IPEWP qualifies as PoE Class 1 — compatible with 802.3af switches without any power budget concern. A 24-port 802.3af switch delivering 370W can support over 90 of these units on power alone. No separate power supply or UPS tap required at the device.
- 95 dB SPL @ 1m Audio Output: At 95 dB SPL measured at 1 meter, the speaker output cuts through ambient noise in parking garages, loading docks, and transit platforms. This is the spec that determines whether someone in a high-noise environment can actually hear the far end — and 95 dB is sufficient for most industrial ambient noise floors without auxiliary amplification.
- SIP 2.0 / RFC3261 Compliance: Native SIP 2.0 means this phone registers directly to any standards-compliant SIP PBX or hosted UCaaS platform — Cisco, Avaya, FreePBX, 3CX, Broadsoft, and others. No proprietary adapter hardware, no vendor lock-in. Pair it with your existing call routing for emergency extensions.
- G.711u, G.711a, G.722 Audio Codecs: G.722 wideband codec support delivers HD voice quality on the emergency call when your PBX supports it — clearer communication in a stressful situation. G.711 fallback ensures compatibility with legacy SIP trunks and older gateways.
- Up to 5 Emergency + 5 Non-Emergency Programmable Numbers: The ability to program five emergency and five non-emergency destination numbers gives facilities managers flexibility to route calls to different dispatch centers, security desks, or maintenance lines without reprogramming the hardware — useful in multi-tenant or campus deployments where call routing changes periodically.
- 2A Relay Contacts (30VDC / 1A @ 125VAC, 250VAC max): The onboard relay contacts allow integration with door strikes, gate controllers, sirens, or strobe lights — triggered on call connect or button press depending on configuration. This turns the emergency phone into an active access control trigger point, not just an audio endpoint.
- -40°F to 140°F Operating Range: This is a genuine extended-temperature spec, not a marketing claim. It covers unheated outdoor enclosures in northern climates and sun-baked southern installations alike. Compare this to standard VoIP endpoints rated to 32°F minimum — those will fail in unheated parking structures during winter.
- Talk-A-Phone Back Box Compatibility: The E-1600-TP2IPEWP is dimensioned to flush-mount directly into a Talk-A-Phone back box — a common infrastructure choice on university campuses and transit systems already deployed with Talk-A-Phone stations. This makes it a direct retrofit candidate for those environments without needing new rough-in.
- 100BASE-TX with Auto Crossover: The single RJ-45 10/100 port with auto crossover eliminates wiring polarity concerns during installation — connect straight-through or crossover cable without checking pin assignments at the patch panel.
Integration and Compatibility
The E-1600-TP2IPEWP connects via a single RJ-45 10/100 Base-T interface and also provides three gel-filled butt connectors for direct wire termination where conduit runs terminate without a jack. The gel-filled connectors are weatherproof by design — appropriate for the EWP rating of this unit. Network compliance includes IEEE 802.3af PoE and SIP 2.0 RFC3261, making it compatible with any standards-based SIP platform. CE, FCC Part 15, and ICES-003 Class A regulatory compliance covers US, Canadian, and European deployments.
For campus and municipal deployments building out a broader emergency phone network, the five programmable emergency numbers allow zone-based routing — calls from a parking structure go to a different queue than calls from a building entrance, all from the same hardware model. If you're planning PoE infrastructure for a multi-station deployment, review our PoE switch selection to ensure switch power budgets and port counts align before installation begins.
Relay contact ratings of 2A at 30VDC / 1A at 125VAC support a range of auxiliary device integrations. Verify the current draw of any relay-driven device (door strike, siren, strobe) against these limits before wiring. For facilities already running Talk-A-Phone infrastructure, this unit provides a direct SIP upgrade path — same back box, same rough-in, modern VoIP operation. Consult our VoIP phone catalog for related SIP endpoint options if you need multiple device types on a single system.
Frequently Asked Questions
Q: Does the E-1600-TP2IPEWP require a separate power supply?
A: No. The E-1600-TP2IPEWP is powered entirely via PoE Class 1 (IEEE 802.3af), drawing under 4 watts. Any 802.3af-compliant switch or PoE injector will power the unit — no separate power supply or local transformer needed.
Q: What is the humidity rating difference between standard IP66 and the EWP version?
A: The standard IP66 rating covers humidity up to 95% non-condensing. The Enhanced Weather Protection (EWP) variant — which is what the E-1600-TP2IPEWP is — extends humidity tolerance up to 100%, making it suitable for environments with condensation, heavy vapor, or near-saturation conditions such as car washes, coastal facilities, and covered wet areas.
Q: Will the E-1600-TP2IPEWP work with our existing SIP PBX?
A: Yes, provided your PBX supports SIP 2.0 (RFC3261). The unit registers as a standard SIP endpoint and supports G.711u, G.711a, and G.722 audio codecs. It does not require proprietary gateways or licensing — configure it like any other SIP extension.
Q: Can the E-1600-TP2IPEWP trigger a door strike or external alarm?
A: Yes. The unit includes relay contacts rated at 2A at 30VDC / 1A at 125VAC (250VAC maximum). These can drive door strikes, sirens, strobes, or other auxiliary devices within those current limits.
Q: What is the minimum operating temperature for the E-1600-TP2IPEWP?
A: The operating temperature range is -40°F to 140°F (-40°C to 60°C). This covers unheated outdoor enclosures in northern climates where standard VoIP endpoints would fail.
Q: Does the E-1600-TP2IPEWP fit into an existing Talk-A-Phone back box?
A: Yes. The E-1600-TP2IPEWP is specifically designed to flush-mount into a Talk-A-Phone back box. If you have existing Talk-A-Phone rough-in infrastructure, this unit installs directly without new back-box work.
The spec that earns the E-1600-TP2IPEWP its place in serious outdoor deployments is the combination of IP66 + EWP pushing humidity tolerance to 100% — most flush-mount emergency phones top out at 95% RH and fail in coastal or industrial moisture environments within a season. I've seen standard-rated units replaced annually at car wash facilities and covered transit platforms; this unit is built to stay in service in those conditions.
Technical Highlights:
- PoE Class 1 (<4W): Under 4 watts means this device consumes less than one-third the power budget of a PoE+ device. On a 24-port 802.3af switch, you can run a full campus emergency call network without power budget concerns or midspan injectors.
- 95 dB SPL @ 1m Speaker: Measured at 1 meter, 95 dB SPL is loud enough to cut through typical parking garage and loading dock ambient noise (typically 70–80 dB). You don't need an external horn speaker in most installations — the built-in audio handles it.
- -40°F to 140°F Operating Range: This isn't a weatherized enclosure rating — it's the device's own thermal spec. That means the electronics themselves survive without a heater in uninsulated northern outdoor installations, and without active cooling in direct-sun southern installations.
Deployment Considerations:
- The three gel-filled butt connectors are the field-termination method when you're landing direct wire runs — confirm your conduit fill and wire gauge before rough-in, since there's no punch-down block or screw terminal on this device.
- Relay contacts are rated 2A at 30VDC / 1A at 125VAC. Door strikes vary widely — a fail-secure magnetic lock can draw 300–500mA at 12VDC (well within spec), but some commercial electrified strikes draw more. Verify the load before wiring the relay output to avoid contact damage.
For university campus blue-light phone retrofits — especially where Talk-A-Phone back boxes are already in the ground — the E-1600-TP2IPEWP (often searched as E 1600 TP2IPEWP) is the most straightforward SIP upgrade path available: existing rough-in, no new conduit, native SIP registration, and a thermal/humidity envelope that handles any North American climate without supplemental conditioning.
