Viking Electronics E-1600-TP-IPEWP ADA VoIP Emergency Phone with Enhanced Weather Protection
Overview
The Viking Electronics E-1600-TP-IPEWP is a SIP-based, ADA-compliant emergency phone designed as a direct physical replacement for Talk-A-Phone ETP-series units — it drops into the existing Talk-A-Phone back box without structural modifications, which means you can migrate aging analog emergency stations to a VoIP emergency phone infrastructure without touching walls or conduit. That's a meaningful labor and code-compliance advantage on retrofit projects in parking structures, campus walkways, and transit facilities. The E-1600-TP-IPEWP ships with Enhanced Weather Protection (EWP), expanding its operational envelope down to -40°F — well beyond what most interior-rated stations can handle.
Key Features
- Talk-A-Phone Back Box Compatibility: The E-1600-TP-IPEWP measures 9.5" x 11.75" x 2" (241mm x 299mm x 51mm) and is engineered to flush-mount directly in a Talk-A-Phone back box. On retrofits, this eliminates saw-cutting, patching, and permit re-submittals for new rough-in — the mechanical footprint is already there.
- PoE Class 1, Under 4 Watts: Drawing under 4W via IEEE 802.3af/802.3at/802.3bt compliant PoE, this station puts almost no load on your switch's power budget. A 30W PoE port can theoretically feed seven of these — relevant when you're powering a string of campus emergency stations from a single closet switch. No local power transformer, no conduit for 120VAC.
- 100 Mbps Full-Duplex Network: The 100Mbps full-duplex connection is more than sufficient for compressed voice traffic and keeps the station compatible with existing Fast Ethernet infrastructure. No need to upgrade edge switches to gigabit just to support emergency phone endpoints.
- Wide Wire Gauge Acceptance (19–26 AWG, max 0.082" insulation): Existing Talk-A-Phone field wiring is often 22 or 24 AWG — this unit accepts the full 19–26 AWG range, so you're not re-pulling cable on a retrofit. Verify insulation diameter against the 0.082" max if you're working with oversized plenum jackets.
- -40°F to 140°F Operating Range: The EWP designation is earned here. At -40°F this station works in unheated parking decks, loading dock vestibules, and outdoor kiosk columns in northern climates. The 140°F upper limit covers sun-baked southern exposures without thermal shutdown.
- Relay Output (2A @ 30VDC / 250VAC max): The onboard relay supports door strike, gate, or auxiliary alert device control — useful when you want the emergency call to simultaneously trigger a strobe or release a mag-lock without running a separate control path from the head end.
- ADA Compliance: Meeting ADA requirements is a code mandate, not a differentiator, but it matters at permitting. The E-1600-TP-IPEWP is ADA-compliant out of the box — one fewer variance to negotiate with the AHJ on new construction or renovation projects.
- Stainless Steel Construction: Stainless resists corrosion, vandalism, and cleaning chemicals — the right material choice for transit stations, parking structures, and campus outdoor enclosures where painted steel would pit and rust inside two winters.
Integration and Compatibility
The E-1600-TP-IPEWP connects to any SIP-compatible IP PBX or VoIP call manager — the same platform managing your desk phones can dispatch and log emergency calls from this station. Because it's designed as a physical replacement for the Viking Electronics Talk-A-Phone ETP line, it integrates directly into existing Talk-A-Phone back boxes in the field, a key advantage when maintaining design consistency across a multi-building campus. The relay output adds a local control loop for downstream devices (strobes, strikes, gates) without additional interface hardware. For PoE planning, the Class 1 draw means standard 802.3af switches are sufficient — no PoE+ budget required. Review your PoE switch port count and power headroom if you're deploying multiple stations on a single IDF. The 100Mbps full-duplex network interface fits any current managed or unmanaged Fast Ethernet or Gigabit edge switch without autonegotiation issues. Wire terminations accept 19–26 AWG conductors up to 0.082" insulation diameter — re-use existing field cable on retrofits wherever gauge falls in range. For new installations, review the VoIP emergency phone selection guide for SIP trunk sizing and call routing considerations relevant to multi-station deployments. The companion model E-1600-TP2IPEWP adds a second call button for applications requiring dual-destination routing from the same station — useful where a single back box must serve both a security dispatch and a facilities emergency line.
Frequently Asked Questions
Q: Does the E-1600-TP-IPEWP physically replace Talk-A-Phone ETP-series units without new back box work?
A: Yes. The E-1600-TP-IPEWP is documented as a direct physical replacement for Talk-A-Phone ETP models and is designed to flush-mount in the existing Talk-A-Phone back box — no new rough-in or wall modification required on retrofits.
Q: What PoE standard does the E-1600-TP-IPEWP require, and how much power does it draw?
A: The unit is IEEE 802.3af/802.3at/802.3bt compliant and draws under 4 watts (Class 1). Standard 802.3af PoE ports are sufficient — no PoE+ budget required.
Q: What wire gauge and insulation diameter does the E-1600-TP-IPEWP accept?
A: The unit accepts 19–26 AWG conductors with a maximum insulation diameter of 0.082 inches. Most existing Talk-A-Phone field wiring in the 22–24 AWG range is compatible without re-pulling cable.
Q: What is the operating temperature range for outdoor installations?
A: The E-1600-TP-IPEWP operates from -40°F to 140°F (-40°C to 60°C), making it suitable for unheated outdoor enclosures in northern climates and sun-exposed southern installations.
Q: Can the E-1600-TP-IPEWP trigger a door strike or auxiliary device during an emergency call?
A: Yes. The unit includes a relay output rated at 2A @ 30VDC / 250VAC maximum, which can drive a door strike, magnetic lock release, or strobe directly without additional interface hardware.
Q: Is the E-1600-TP-IPEWP ADA compliant?
A: Yes, the E-1600-TP-IPEWP is ADA compliant, satisfying accessibility code requirements for emergency communication stations in commercial and institutional facilities.
The spec I keep coming back to on the E-1600-TP-IPEWP is the -40°F lower temperature limit paired with under-4W PoE Class 1 draw — that combination tells you exactly what this unit is engineered for: long cable runs to outdoor emergency stations in harsh climates, powered entirely from a central closet switch with no local power infrastructure at the endpoint. On a university campus or transit authority with 40-plus stations spread across open plazas and parking structures, that's the whole installation model.
Technical Highlights:
- PoE Class 1 (<4W): At under 4 watts, a single 30W 802.3af port can support up to seven stations simultaneously — critical for closet switch budgeting when IDF locations are sparse and you're home-running multiple emergency phones to one switch.
- -40°F to 140°F Operating Range: The 180°F total swing means one SKU covers both a Minnesota parking ramp in January and an Arizona surface lot in August — no region-specific variants to track in your project BOM.
- Relay Output (2A @ 30VDC/250VAC): The onboard relay handles direct door strike or strobe loads up to 2A — eliminates the relay module you'd otherwise wire into the panel just to get a local annunciation output at the station.
Deployment Considerations:
- Confirm your SIP call manager supports the VoIP profile Viking uses before commissioning — test call setup, teardown, and relay trigger behavior in a lab environment before field deployment across a large station count.
- The 0.082" maximum insulation diameter is the one spec that can surprise you on retrofits: oversized plenum-rated jackets occasionally exceed this. Measure before pulling the old station — you may need to re-terminate a short tail rather than land existing cable directly.
This unit is the right call for campus-wide Talk-A-Phone retrofit projects where the back boxes are already in place and the goal is converting to SIP VoIP without a construction change order. The mechanical drop-in fit and the Class 1 power profile make it a straightforward line item for facilities teams that have already committed to a SIP PBX platform.
