Viking E-40BN-EWP Oil Rubbed Bronze Entry Phone IP67 EWP

Viking Electronics E-40BN-EWP Oil Rubbed Bronze Entry Phone with Enhanced Weather Protection

The Viking Electronics E-40BN-EWP is a single-gang, telephone line powered entry phone built for exterior door and gate applications where aesthetics, durability, and genuine weather resistance are non-negotiable. Finished in oil rubbed bronze over an 18-gauge 304 stainless steel faceplate — with a 316 stainless steel push button — this unit is engineered to hold up in coastal, industrial, and high-humidity environments that corrode cheaper hardware within a season. The E-40BN-EWP (often searched as E 40BN EWP) ships with Viking's Enhanced Weather Protection (EWP) package, pushing the enclosure rating to IP66 while the push button itself carries an IP67 rating. No separate power supply, no separate wiring run for power — the phone draws everything it needs from the telephone line itself.

Overview

Compact enough to flush mount in a standard single gang electrical box (2.25" deep x 2.00" wide x 2.84" tall) or surface mount with an optional VE-3x5 enclosure, the E-40BN-EWP fits retrofit and new construction alike without requiring oversized rough-in. The faceplate measures 4.875" x 3.125" x 0.18", sitting nearly flush against the wall — a clean look that works in upscale residential lobbies, commercial building entries, and gated community call boxes. The blue LED indicator gives visitors clear visual confirmation that the unit is active, reducing misdialed calls and support calls about whether the system is working.

Key Features

• IP67 Push Button / IP66 EWP Enclosure: IP67 on the push button means the switch itself survives temporary submersion — relevant for recessed installations that collect standing water. IP66 on the EWP housing stops sustained, high-pressure water jets. Together these ratings make the E-40BN-EWP a legitimate choice for covered exterior entries, parking structures, and marina gate posts where a standard weatherproof label would fall short.
• Operating Range -30°F to 150°F: This is a real-world spec that separates entry phones. At -30°F, Minnesota loading docks, mountain ski resort lodges, and northern Canada gate installations stay operational without heater options or seasonal removal. At 150°F, the unit survives Arizona summer sun on a west-facing wall that standard units can't handle.
• Up to 100% Humidity (EWP Model): The EWP treatment seals against condensation, steam, and fog — conditions that kill unprotected electronics over a single winter. Critical for indoor-outdoor transitional spaces: greenhouse entry, car wash bay access, pool house call stations.
• Telephone Line Powered (18V DC min, 20mA min): No low-voltage home run, no PoE switch port, no plug-in transformer. If there's a POTS line or a line-simulating PBX port at the door, the E-40BN-EWP runs off it. This makes retrofitting legacy door phone infrastructure straightforward — swap the old unit, done.
• 62dB Speaker @ 1m: Enough output for a sheltered entry or small lobby vestibule. This is not a loud-venue paging speaker — in a busy loading dock with ambient machinery noise you may want an amplified model. For standard commercial entry, 62dB at one meter is workable without distortion.
• 316 Stainless Steel Push Button: Grade 316 (marine-grade) stainless is specified for the button because buttons take finger oils, cleaning chemicals, and direct moisture contact every day. Using 316 rather than standard 304 on the high-contact surface meaningfully extends corrosion resistance in coastal and chemical-exposure environments.
• 18-Gauge 304 Stainless Steel Faceplate: Thick enough to resist casual impact and vandal prying. The oil rubbed bronze finish is applied over stainless, not aluminum or zinc die-cast, so dents expose steel rather than a softer substrate — the unit retains structural integrity even after physical abuse.
• CPC Auto-Disconnect (300ms min): Calling Party Control disconnect prevents the entry phone from holding a telephone line open if the called party hangs up without explicitly releasing. In multi-tenant buildings this matters — a stuck call can block the line for the next visitor. 300ms response is fast enough that end users never notice a delay.
• REN 0.8A: A Ringer Equivalence Number of 0.8 means this device consumes 80% of the one-REN budget on a typical POTS line. If you're pairing it with other ringers on the same line, budget accordingly — one E-40BN-EWP plus one standard phone leaves 0.2 REN available before the line's ringing capacity is consumed.
• Ring Voltage: 25V AC RMS minimum: Confirms compatibility with standard telephone ring signaling. Relevant when connecting to newer VoIP ATAs — verify the ATA's ring voltage output meets or exceeds 25V AC RMS before installation.
• Available in Four Faceplate Finishes: Oil Rubbed Bronze (this model), Brushed Stainless Steel, Satin Black, and Satin White. If the architectural spec changes after rough-in, the faceplate is interchangeable within the E-40 family without re-wiring.

Integration & Compatibility

The E-40BN-EWP connects to any standard analog telephone line, POTS-line-simulating PBX port, or VoIP ATA that delivers the minimum 18V DC talk battery and 25V AC RMS ring voltage. It does not require a proprietary controller, hub, or app — the call goes out as a standard telephone call to whatever extension or number is programmed at the PBX or ATA. This simplicity makes it compatible with virtually any phone system that provides an analog FXS port: Cisco, Avaya, Mitel, Grandstream ATAs, Algo, and comparable platforms.

For installations requiring a surface-mount enclosure rather than a single gang box, pair with the Viking VE-3x5 surface mount enclosure. For coverage planning on entry phone systems, consider the full Viking entry phone family for multi-door or multi-tenant deployments.

If your project also requires video at the entry point, review our outdoor IP camera selection to pair with this audio-only entry phone. For access control integration and door release wiring, see our access control category for compatible electric strike and magnetic lock options.

Frequently Asked Questions

Q: What is the IP rating on the E-40BN-EWP, and does it cover the entire unit?

A: The E-40BN-EWP carries two separate ratings: IP67 on the push button switch (dust-tight, survives temporary submersion) and IP66 on the overall EWP enclosure (dust-tight, protected against high-pressure water jets). The EWP (Enhanced Weather Protection) treatment is what achieves the IP66 enclosure rating — the base E-40-BN without EWP does not carry the IP66 enclosure rating.

Q: Does the E-40BN-EWP require a separate power supply?

A: No. The E-40BN-EWP is telephone line powered and draws everything it needs from the connected telephone line, requiring a minimum of 18V DC talk battery voltage and 20mA loop current. No transformer, no PoE, no external power run to the door is needed.

Q: What phone system or PBX is required to use the E-40BN-EWP?

A: Any system that provides a standard analog (FXS) port with at least 18V DC talk battery and 25V AC RMS ring voltage will work. This includes traditional POTS lines, analog PBX extensions, and VoIP ATAs (Grandstream HT series, Cisco SPA, Algo, etc.). Verify your ATA's ring voltage output before installation — some low-cost ATAs output less than 25V AC RMS.

Q: Can the E-40BN-EWP be surface mounted, or does it require a wall box?

A: The unit flush mounts in a standard single gang electrical box (minimum 2.25" deep x 2.00" wide x 2.84" tall). For surface mounting without a recessed box, Viking offers the optional VE-3x5 surface mount enclosure as an accessory. The faceplate itself measures 4.875" x 3.125" x 0.18".

Q: What is the operating temperature range for the E-40BN-EWP?

A: The E-40BN-EWP is rated -30°F to 150°F (-34°C to 65°C), making it suitable for both extreme cold climates and hot sun-exposed installations without supplemental heating or cooling.

Q: Is the oil rubbed bronze finish the only option, or can I get this model in other finishes?

A: The BN suffix designates oil rubbed bronze. The E-40 series is also available in Brushed Stainless Steel, Satin Black, and Satin White finishes. All share the same stainless steel construction and EWP options — only the faceplate finish differs, and faceplates are interchangeable within the family.

Ted Perry

The E-40BN-EWP is one of those products where the spec sheet details matter more than the headline. What catches my attention is the dual IP rating structure: IP67 on the push button and IP66 on the EWP enclosure. That distinction is deliberate — the button is the highest-abuse point on any entry phone, and Viking spec'd marine-grade 316 stainless for it specifically. Most competitors use a single blanket rating that doesn't differentiate the component most likely to fail first.

Technical Highlights:

• Telephone Line Powered (18V DC / 20mA min): No home run for power. On retrofit jobs where conduit is already pulled for a POTS line, this eliminates a change order. The 20mA minimum loop current requirement is well within what any functioning analog line delivers — I've never seen this be a problem in the field.
• CPC Disconnect 300ms: Calling Party Control at 300ms means the line clears fast when the called party hangs up. In multi-tenant or high-traffic entries, a slow CPC disconnect creates a queue of frustrated visitors — 300ms response keeps the line available for the next call immediately.
• -30°F to 150°F Operating Range: This is a genuine differentiator. At -30°F, most entry phones either fail to ring or produce degraded audio. At 150°F on a west-facing bronze panel in Phoenix, many units throttle or distort. The E-40BN-EWP's rated range covers both extremes without supplemental hardware.

Deployment Considerations:

• The single gang box requirement (2.25" deep x 2.00" wide x 2.84" tall) is standard, but confirm depth before rough-in — shallow old-work boxes that are only 1.5" deep won't accommodate the phone body (72mm x 46mm x 42mm). Use the VE-3x5 surface enclosure if depth is constrained.
• REN of 0.8A means this device is a meaningful load on the line's ringing capacity. On a shared analog line with other ringers, confirm total REN doesn't exceed the line's capacity (typically 5 REN) — and verify your VoIP ATA outputs the required 25V AC RMS ring voltage before you close the wall.

This unit is the right call for upscale multifamily entries, gated community call boxes, and commercial building lobbies where the architect specified a bronze or dark finish and the installation team needs a phone that won't need replacement after the first hard winter or summer.
