Viking Electronics E-60-SS-EWP Double Gang Stainless Steel Entry Phone with EWP
The Viking Electronics E-60-SS-EWP is a telephone line-powered, vandal-resistant entry phone built for demanding access points — loading docks, parking structures, correctional facilities, industrial plants, and any outdoor location where conventional intercoms fail within a season. It flushes into a standard double gang box or mounts on a surface, and with the included Enhanced Weather Protection (EWP) enclosure, it carries an IP66 ingress rating that keeps wind-driven rain and airborne debris out of the electronics entirely. The push-button switch itself is independently rated IP67 — submersion-grade — so a pressure wash or standing water in a recessed mount won't kill it.
When This Is the Correct Choice
Deploy the E-60-SS-EWP where you need a station that survives without a dedicated power run. It draws everything it needs from the telephone line: minimum 18V DC talk battery and 20mA loop current are the only requirements. If your site already has POTS or a PBX loop run to the door, this installs with two gel-filled butt connectors — no panel, no transformer, no power supply to mount alongside it.
The operating range, -30°F to 150°F, covers walk-in freezer vestibules, sun-baked desert guard shacks, and northern outdoor installations in the same SKU. The 100% humidity tolerance under the EWP enclosure means condensation cycling won't degrade the electronics over time.
Key Features
- 18-Gauge 304 Stainless Steel Faceplate (4.875" x 4.938"): 304 SS resists corrosion in coastal and industrial environments. At 0.17" thick and only 2.84" x 1.8" x 1.65" for the phone body, the profile stays flush and clutter-free on a finished wall.
- 316 Stainless Steel Push Button and Mounting Hardware: The call button and all 6-32 x 3/4" mounting screws are marine-grade 316 SS — the alloy used on boat hardware and offshore equipment. Where salt air or chemical washdowns are routine, 316 resists pitting that would corrode standard 304 fasteners within months.
- IP67 Push Button / IP66 EWP Enclosure: IP67 means the switch withstands temporary submersion. IP66 for the full enclosure means sustained high-pressure water spray won't penetrate. Together, these ratings handle pressure washing, flooding, and zero-maintenance outdoor operation.
- Telephone Line Powered (18V DC min / 20mA min): No separate power supply, no conduit run for 120VAC, no UPS to maintain at the door. The phone draws from the loop — meaning it stays live during a power outage as long as your PBX or central office is up.
- Automatic Disconnect (CPC, 300ms minimum): When the called party hangs up, the phone disconnects automatically via CPC signal. This prevents stuck-open calls from tying up the line or leaving the microphone live at the door — important in any access-controlled or secure facility.
- Blue LED Indicator: The blue LED gives visitors a clear visual confirmation the unit is active and powered, reducing repeated button presses and nuisance calls at busy entry points.
- 62dB Speaker @ 1m: Loud enough to be understood in moderate ambient noise — a covered loading dock, a parking garage, or a busy lobby vestibule. Not a PA speaker, but sufficient for a clear two-way conversation at arm's reach.
- Carbon Fiber Reinforced Plastic Speaker Screen: CFRP resists the flex and crack that defeats polycarbonate screens under impact or thermal cycling. On a vandal-target entry point, this matters more than it appears.
- REN 0.8A: Standard ringer equivalence — compatible with the vast majority of PBX analog line cards and central office lines without any special loop configuration.
- Ring Voltage: 25V AC RMS minimum: Confirm your PBX or analog gateway delivers at least 25V AC ring voltage. Most enterprise systems do; some IP-to-analog adapters (ATAs) ring at lower voltages — verify before deploying on a VoIP analog port.
Integration and Compatibility
The E-60-SS-EWP connects to any analog POTS line, PBX analog extension, or FXS port that meets the 18V DC talk battery, 20mA loop current, and 25V AC ring voltage minimums. It is not a VoIP device — for SIP/VoIP integration, Viking offers the E-60-SS-IP-EWP variant. Pair with a relay-equipped access control panel or a Viking door strike controller if you need door release on answer. The two gel-filled butt connectors supplied handle the wiring termination without a punchdown block.
For entry phones and door intercoms, the double gang flush mount keeps the installation compliant with ADA-height requirements when positioned correctly. Surface mount is available for retrofit where cutting into a finished wall isn't practical. The optional VE-5x5 enclosure provides the EWP-rated housing included with this SKU — no separate purchase required for weather protection at this model level. Review the full Viking Electronics intercom and access line for companion controllers, door strike interfaces, and multi-button expansion units.
If your project involves coordinating entry phone placement with camera coverage, consult a camera selection guide to ensure the door entry point is covered by an appropriately placed IP camera — entry phones and surveillance cameras are frequently co-located at access control points. For switch infrastructure to support any IP devices at the same location, see the PoE switch category for powered port options.
Frequently Asked Questions
Q: Does the E-60-SS-EWP require an external power supply?
A: No. The E-60-SS-EWP is telephone line powered, drawing from the analog loop. It requires a minimum talk battery of 18V DC and 20mA loop current from your PBX analog port, POTS line, or FXS gateway — no separate power supply or AC wiring to the door.
Q: What is the ingress protection rating of the E-60-SS-EWP?
A: The push button switch is rated IP67 (submersion-rated). The full enclosure with the EWP (Enhanced Weather Protection) housing is rated IP66, meaning it withstands sustained high-pressure water spray. The unit also tolerates up to 100% humidity in the EWP configuration.
Q: Will the E-60-SS-EWP work with a VoIP phone system?
A: The E-60-SS-EWP is an analog telephone line-powered device — it connects to a POTS line or a PBX analog extension (FXS port). For native SIP/VoIP integration without an analog adapter, Viking offers the E-60-SS-IP-EWP, the VoIP variant in the same E-60 family.
Q: What is the operating temperature range?
A: -30°F to 150°F (-34°C to 66°C). This covers cold-climate outdoor installs, walk-in freezer vestibules, and high-heat environments such as sun-exposed desert entries or equipment rooms.
Q: What mounting options does the E-60-SS-EWP support?
A: The E-60-SS-EWP flushes into a standard double gang electrical box or surface mounts using the optional VE-5x5 enclosure. The VE-5x5 provides the Enhanced Weather Protection housing and is included with this EWP-designated model.
Q: What hardware is the faceplate and push button made from?
A: The faceplate is 18-gauge 304 stainless steel. The push button is 316 stainless steel — marine grade, with higher chloride and corrosion resistance than 304. Mounting screws are also marine-grade 316 stainless (6-32 x 3/4").
The E-60-SS-EWP is one of those products I recommend when the site already has analog infrastructure and the integrator doesn't want to add a power supply at every door. The 18V DC / 20mA loop minimum is achievable on essentially every enterprise PBX analog card I've encountered — so you run one pair of wire, terminate with the two gel-filled butt connectors, and you're done. The automatic CPC disconnect at 300ms is the spec most people overlook: without it, a door phone on a shared line becomes a liability in any secure facility.
Technical Highlights:
- 316 SS Push Button and Hardware: 316 stainless is the alloy used in marine and chemical processing environments. Specifying this for a coastal parking garage or a food processing plant entry isn't over-engineering — 304 fasteners show rust staining within 12-18 months in salt-air conditions; 316 does not.
- IP67 Switch / IP66 EWP Enclosure: These are independently rated — the button survives submersion, and the housing survives a directed hose-down. Pressure washing a dock entry area won't compromise either. Up to 100% humidity tolerance makes this viable in car wash facilities or covered outdoor entries with condensation cycling.
- -30°F to 150°F Operating Range: This is a wide enough band that a single SKU covers northern outdoor winters and sun-baked southwestern mechanical room entries. It's also the reason this unit works at walk-in cooler/freezer vestibule doors without a heated housing.
Deployment Considerations:
- Verify your ATA or IP-PBX FXS port delivers at least 25V AC RMS ring voltage before deployment. Some lower-cost ATAs ring at 20-22V — the E-60-SS-EWP won't ring reliably on those ports without a ring booster inline.
- If the door release function is required, you'll need a separate relay board or Viking door strike controller — the E-60-SS-EWP itself handles only the voice path; there is no built-in relay output in this model.
This unit is the right call for industrial and municipal entry points — water treatment facilities, correctional perimeter doors, cold-storage warehouse entries — where analog infrastructure is in place, power at the door is unavailable, and the hardware needs to outlast the building's maintenance cycle without corroding.
