Viking E-40-WH Satin White Entry Phone Telephone Line Powered

Viking Electronics E-40-WH Satin White Entry Door Phone

Overview

The Viking Electronics E-40-WH is a compact, telephone line powered, handsfree door entry phone designed for commercial and light-industrial access points where you need two-way audio without running a separate power supply. The E-40-WH draws power directly from the phone line — minimum 18V DC at 20mA — so there is no transformer to wire, no AC outlet to find, and no power run to budget. It installs into a standard single-gang box or surfaces mounts with an optional VE-3x5 adapter, keeping rough-in costs minimal.

The satin white powder-paint finish over an 18-gauge 304 stainless steel faceplate (4.875" x 3.125" x 0.18") gives the unit a clean, professional appearance suitable for office lobbies, apartment building entries, and school vestibules. For the full Viking Electronics entry phone lineup, including bronze and other finish variants, see the brand catalog.

Key Features

• Telephone Line Powered (18V DC / 20mA min): No separate power supply or low-voltage transformer needed. As long as the line delivers at least 18V DC and 20mA, the phone operates — simplifying rough-in and eliminating one potential failure point in the field.
• IP67 Sealed 316 Stainless Steel Push Button: The call button is fully rated for dust-tight and temporary submersion protection. In a covered outdoor vestibule or a wash-down corridor, the button itself won't corrode or fail from moisture intrusion. Solid 316 stainless resists chloride environments better than the more common 304 alloy.
• Operating Range -30°F to 150°F: This range covers unheated exterior vestibules in northern climates and sun-baked metal enclosures in southern ones. Most competitive entry phones are rated to -4°F or 0°F — the E-40-WH's lower limit gives integrators more confidence in cold-storage facility and northern-exposure installations.
• 62 dB Speaker Output at 1m: Loud enough for a noisy loading dock or a windy exterior entry without distortion. The unit also includes microphone and speaker volume controls, so you can tune for quieter interior lobby installations without a separate attenuator.
• Automatic CPC Disconnect (300ms min): The phone monitors for a CPC (Calling Party Control) signal from the PBX or CO and disconnects the call automatically. No caller has to manually hang up, and the line clears reliably — relevant anywhere you need auditable call termination or are integrating with an auto-attendant.
• 25V AC RMS Ring Voltage, REN 0.8A: Compatible with standard POTS lines and most PBX analog ports. The 0.8 REN draw is well within the typical 4-REN per line limit, so combining this phone with other endpoints on the same line is straightforward.
• Flush or Surface Mount: Fits a standard single-gang electrical box for a clean flush installation or mounts surface with the optional VE-3x5 adapter. For planning your intercom and entry phone installations, verify gang-box depth before rough-in — the phone body extends 42mm (1.65") behind the faceplate.
• Weather and Vandal Resistant Construction: 18-gauge 304 stainless steel faceplate resists impacts and tampering. Combined with the IP67 button and sealed enclosure, this is a durable choice for exposed entries that see regular physical contact.

Integration and Compatibility

The E-40-WH connects to any standard analog telephone line or PBX analog extension. It does not require a proprietary controller — if your PBX delivers a standard POTS-compatible analog port, this phone works. Door strike or electric lock control is handled by the connected PBX or a relay module, not built into the unit itself. For installations requiring door release integration, pair this entry phone with a compatible access control relay or door controller. The CPC disconnect feature requires that the host PBX or CO supports CPC signaling; verify with your telephony platform before specifying.

The E-40-WH is also available in a bronze finish (E-40-BN) and with an enhanced weather protection option (E-40-WH-EWP) for more exposed outdoor locations. If you need a broader look at entry communication options, the entry phone category covers both analog and IP-based systems.

Frequently Asked Questions

Q: Does the E-40-WH require an external power supply?

A: No. The E-40-WH is telephone line powered and operates from the line voltage itself — minimum 18V DC at 20mA. No separate transformer or power supply is required.

Q: What mounting options are available for the E-40-WH?

A: The E-40-WH installs flush into a standard single-gang electrical box or can be surface mounted using the optional VE-3x5 adapter. The phone body depth is 42mm, so confirm gang-box depth during rough-in.

Q: How cold can the E-40-WH operate?

A: The operating temperature range is -30°F to 150°F (-34°C to 65°C), making it suitable for unheated vestibules and cold-storage facility entries in northern climates.

Q: Is the push button on the E-40-WH weather resistant?

A: Yes. The push button is IP67 rated and constructed from solid 316 stainless steel, providing full dust-tight protection and resistance to temporary water submersion.

Q: Will the E-40-WH work with my PBX?

A: The E-40-WH connects to any standard analog telephone line or PBX analog extension. It draws 0.8 REN, which is well within standard per-line limits. CPC automatic disconnect requires that your PBX or CO supports CPC signaling — confirm this with your telephony platform.

Q: What is the difference between the E-40-WH and the E-40-WH-EWP?

A: The E-40-WH-EWP adds enhanced weather protection (EWP) for more exposed outdoor locations. The E-40-WH is suited for covered entries or indoor locations; choose the EWP variant when the installation is directly exposed to rain or driving weather.

The E-40-WH is one of those devices that earns its place specifically because of what it does NOT need — no power supply, no transformer, no extra conduit run. The telephone line powered design (18V DC minimum, 20mA) is the whole value proposition for retrofit installations where pulling a new power circuit isn't in scope.

Technical Highlights:

• IP67 Push Button: The 316 stainless call button handles full dust ingress and temporary submersion — a meaningful step above IP54 or IP65 buttons common at this price point, especially in wash-down corridors or coastal environments where 304 stainless would show surface rust within a year.
• -30°F Low-End Rating: Most entry phones bottom out at -4°F to 14°F. The E-40-WH's -30°F floor is a genuine differentiator for cold-storage loading dock entries and northern-climate exterior vestibules where alternatives simply fail in January.
• CPC Disconnect at 300ms: Automatic call termination on CPC signal prevents abandoned open lines on the PBX extension. In multi-tenant or high-traffic entry applications, that line-clearing behavior keeps the system clean without relying on caller discipline.

Deployment Considerations:

• The phone body is 42mm deep (72mm x 46mm x 42mm overall) — verify gang-box depth before rough-in. A standard 2-1/8" deep single-gang box is typically sufficient, but shallow retrofit boxes will not work.
• CPC automatic disconnect is only active if the connected PBX or CO delivers a CPC signal on hang-up. Analog ports on some hosted VoIP systems do not generate CPC — test your platform's analog FXS behavior before finalizing the design.

For a covered apartment building vestibule or a school main entrance on an analog PBX extension, the E-40-WH (also searched as E 40 WH) is the right call: line-powered, cold-rated, and built to take daily physical contact without corroding.
