Viking Electronics E-70-BK-EWP Textured Black Entry Phone with Proximity Card Reader and EWP
Overview
The Viking Electronics E-70-BK-EWP is a telephone-line-powered, two-way handsfree entry phone with a built-in 125KHz proximity card reader, engineered for access-controlled entry points that need audio intercom and credential validation in a single flush-mount unit. The textured black powder-coat finish over an 18-gauge 304 stainless steel faceplate gives it the durability profile of commercial exterior hardware — not a residential intercom dressed up for business use. With IP66 weather protection on the EWP housing and IP67 on the push button switch itself, this unit handles direct rain, hose-down environments, and dusty industrial sites without additional enclosure work.
Key Features
- Telephone Line Powered (18V DC / 20mA minimum): No separate power supply, no PoE run, no 12V transformer — the existing POTS or VoIP line delivers everything the unit needs. That simplifies rough-in on retrofit projects where pulling a new power circuit is expensive.
- 125KHz Proximity Card Reader, 26-bit Wiegand: Compatible with Viking PRx-C, PRx-C-ISO, PRx-FOB, HID, and AWID credentials — the four most common card formats in commercial access control. Read range of 1.25" to 2.0" is typical for proximity, keeping tailgating risk low while remaining usable with a gloved hand.
- IP66 Housing / IP67 Push Button: IP66 means sustained water jets won't penetrate the enclosure — appropriate for building exteriors, covered loading docks, and covered parking structures. The IP67-rated push button adds submersion tolerance at the highest-wear contact point.
- Operating Range -30°F to 150°F, Up to 100% Humidity: This operating envelope covers unheated northern vestibules in winter and sun-exposed southern facades in summer without special provisions. Most competitive units cap out around 140°F, so the extra headroom matters on west-facing walls.
- Dual LED Indicators (Red and Blue): The blue LED provides visual call-in-progress confirmation; the red LED signals access-granted or system status. On a busy entry point this gives users immediate visual feedback without needing to hear an audible tone in high-ambient-noise environments.
- Automatic CPC Disconnect (300ms minimum): The unit monitors loop current for a CPC (Calling Party Control) signal from the connected phone system and automatically disconnects after 300ms — no manual hang-up required on the door-side, which matters when the remote station operator controls call termination.
- 62dB Speaker at 1 Meter: Loud enough for most covered entry points with ambient noise. Not designed for open outdoor loading docks with heavy equipment — for those scenes a supplemental amplifier or different model is worth evaluating.
- Dual Mounting Options: Flush-mounts into a standard double-gang electrical box (faceplate: 4.875" x 4.938" x 0.17") or surface-mounts with the optional VE-5x5 enclosure. The flush option keeps the profile minimal on finished wall surfaces; the VE-5x5 works on masonry, concrete, and locations where cutting into the wall isn't feasible.
Integration and Compatibility
The E-70-BK-EWP (often searched as E 70 BK EWP) connects to any standard telephone system that provides a minimum 25V AC RMS ring voltage and supports CPC disconnect signaling. The 26-bit Wiegand output from the card reader integrates directly with access control panels that accept standard Wiegand input — no proprietary controller required. Verify your panel supports 26-bit Wiegand and that your card inventory matches one of the supported formats (HID, AWID, Viking PRx family) before ordering.
Frequently Asked Questions
Q: What card technologies does the E-70-BK-EWP proximity reader support?
A: The reader operates at 125KHz and supports Viking PRx-C, PRx-C-ISO, PRx-FOB, HID, and AWID credential formats using 26-bit Wiegand output. Most standard commercial proximity cards and fobs in these formats will work at a read range of 1.25" to 2.0".
Q: Does the E-70-BK-EWP require an external power supply?
A: No. The unit is telephone line powered, requiring a minimum of 18V DC at 20mA from the connected phone line. No separate power supply or PoE infrastructure is needed.
Q: What is the weather protection rating for the E-70-BK-EWP?
A: The EWP (Enhanced Weather Protection) housing carries an IP66 ingress protection rating, and the push button switch is independently rated IP67. IP66 covers sustained water jets; IP67 adds short-term submersion tolerance at the button itself.
Q: What mounting options are available?
A: The unit flush-mounts into a standard double-gang electrical box using the 4.875" x 4.938" faceplate, or surface-mounts using the optional Viking VE-5x5 enclosure for masonry and concrete installations.
Q: What is the operating temperature range?
A: The E-70-BK-EWP operates from -30°F to 150°F at up to 100% humidity, covering most North American exterior installation environments without additional thermal management.
Q: What phone system ring voltage does the unit require?
A: The unit requires a minimum ring voltage of 25V AC RMS. Verify your phone system or VoIP ATA meets this threshold — some low-voltage ATAs used in SIP deployments may fall short and prevent the unit from ringing.
The E-70-BK-EWP stands out in the single-gang entry phone segment primarily because of its thermal envelope: -30°F to 150°F at 100% humidity covers genuinely harsh exterior conditions where cheaper units fail within a season. That combined with the IP66 EWP housing and IP67-rated push button means you're not adding a separate weatherproof enclosure to hit a code requirement — the unit ships ready for exterior installation as-is.
Technical Highlights:
- 26-bit Wiegand Card Reader: The 125KHz reader at 1.25"–2.0" range outputs standard 26-bit Wiegand — direct wire to virtually any commercial access control panel without a protocol translator. HID and AWID compatibility means existing card inventories almost always carry over.
- Telephone Line Power (18V DC / 20mA): Eliminates a separate power run entirely. On retrofit projects with existing POTS infrastructure, this is a meaningful labor saving — particularly in retrofitting older apartment entries or industrial access points where conduit capacity is already tight.
- CPC Auto-Disconnect at 300ms: The CPC loop-current detection lets the remote station operator terminate the call cleanly without the door-side unit requiring any action. This is a real operational detail in high-traffic entries where call management falls to a front desk or guard station.
Deployment Considerations:
- Confirm your phone system or SIP ATA delivers at least 25V AC RMS ring voltage before deploying — some budget ATAs in SIP retrofits run low and will prevent the unit from ringing despite otherwise valid line voltage.
- The 62dB speaker at 1 meter is adequate for covered vestibules and indoor lobbies but will be marginal on open exterior loading docks with forklift or HVAC ambient noise — factor in the acoustic environment before specifying.
This unit is the right call for exterior access points on commercial buildings, multifamily properties, and industrial facilities where the installer needs a single device to handle intercom, card credential, and telephone-system integration without pulling a dedicated power circuit.
