Viking Electronics E-32 Stainless Steel Handsfree Speaker Phone with Dialer
The Viking Electronics E-32 is a telephone-line-powered, flush-mount handsfree speaker phone built for demanding entry-control applications — parking structures, industrial facilities, correctional environments, and outdoor vestibules where standard intercom hardware simply doesn't survive. The E-32 (often searched as E 32) draws power directly from the phone line, so there's no separate power supply to wire, no transformer to mount, and no AC outlet to find in a concrete wall. If you're specifying an entry intercom for a location that already has a POTS or analog PBX extension run to it, this is the most straightforward path to a vandal-resistant, weather-hardened solution.
Overview
Designed for flush mounting in a standard double-gang electrical box — minimum 3.65"W × 2.84"H × 2.25"D — the E-32 integrates cleanly into door-jamb and wall-panel installations where protruding hardware is a liability. The 14-gauge 316 brushed stainless steel faceplate isn't cosmetic: 316-grade alloy resists chloride corrosion, making it suitable for coastal, food-processing, and chemical-exposure environments where 304-grade hardware discolors and pits within months. Permanent laser-etched graphics ensure markings remain legible after years of UV exposure and cleaning cycles that would fade painted or printed labels.

Key Features
- Telephone Line Powered (24V DC minimum, 20mA loop current): The E-32 draws everything it needs from the phone line itself — no wall wart, no DC power supply, no conduit home-run for power. On a long cable run, verify your PBX or POTS loop can sustain 20mA at 24V DC; if you're losing voltage over distance, a line booster fixes it without changing the device.
- IP67-Rated Internal Switch: The internal switch is sealed to IP67 — full temporary submersion. The EWP assembly carries IP66, protecting against powerful water jets. In practice, this means a pressure washer aimed at the faceplate during facility cleaning won't damage the unit. If you're specifying for dock doors or wash-down zones, this is the spec to verify against your facility's cleaning protocol.
- -30°F to 170°F Operating Range (-34°C to 77°C): This is a real differentiator for unheated stairwells, outdoor enclosures, or rooftop equipment rooms. Most residential-grade intercoms fail below 32°F or cook out above 120°F in direct summer sun — the E-32's rated range covers both extremes.
- 316 Brushed Stainless, 14-Gauge Faceplate with T-10 Torx Security Screws: The heavier-gauge 316 SS resists denting and tampering, while T-10 Torx fasteners deter casual removal with common tools. Faceplate, mic, and speaker gaskets work together to maintain the IP ratings even after repeated access for service.
- Programmable Dialer — Up to 5 Numbers: The built-in dialer can be programmed to ring up to five destinations in sequence or by selection. For a loading dock that needs to reach a guard station, a backup security desk, and a facilities manager in rotation, this eliminates the need for an external auto-dialer or a hunt group at the PBX.
- Automatic Noise Canceling (ANC): Built-in ANC compensates for high-ambient-noise environments — compressor rooms, manufacturing floors, outdoor locations near HVAC equipment. Without this, an entry phone in a mechanical room typically produces unintelligible audio on the receiving end.
- Auto-Answer Selectable: When enabled, the phone answers incoming calls automatically — useful for guard stations that need to monitor an entry point passively, or supervisor-to-door intercom check-ins that don't require user interaction at the door.
- Blue Off-Hook LED Indicator: A visible status indicator confirms an active call, which matters in high-traffic or noisy entry areas where the user may not be able to hear a dial tone. Guards monitoring from a distance can see call state at a glance.
- Self-Draining Mic Mount: Water ingress through the mic port is the most common failure mode for outdoor speaker phones. The self-draining mic mount channels water out rather than pooling it against the microphone element, extending service life in rain-exposed installations.
- Mylar Speaker: Mylar speaker cones are dimensionally stable across the rated temperature range and resist moisture degradation better than treated paper — a practical choice for the environments this device targets.
- Gel-Filled Butt Connector Terminations: Connections are made with gel-filled butt connectors that seal against moisture intrusion at the splice — a correct approach for outdoor and high-humidity wiring that avoids the corrosion failures common with unprotected crimp splices.
- REN 0.5A, 25VAC RMS Minimum Ring Voltage: With a Ringer Equivalence Number of 0.5, the E-32 draws minimal load on the phone line and will ring reliably on lines that can deliver 25VAC RMS — standard for POTS and most analog PBX ports.
Integration and Compatibility
The E-32 connects to any analog POTS line or analog PBX extension — it is not a VoIP or SIP device. If your environment has migrated to a SIP-based phone system, Viking offers the E-32-IP as a parallel model designed specifically for VoIP entry phone deployments with PoE. For analog infrastructure, the E-32 integrates without additional hardware: wire the two-conductor phone line to the gel-filled butt connectors, program the dialer, and commission. The unit mounts into a standard double-gang box — a 4" × 4" × 2.12" plastic electrical box is included to simplify rough-in. Pair with a door access control system or electric strike for full entry management, or use standalone for call-only entry notification. For sites requiring a complete entry solution including video, review the entry phones and intercoms category for companion products.
Frequently Asked Questions
Q: Does the E-32 require an external power supply?
A: No. The E-32 is telephone line powered, drawing everything it needs from the phone line itself. The minimum requirements are 24V DC talk battery and 20mA loop current — standard on most POTS lines and analog PBX extensions. No separate AC or DC power supply is needed.
Q: What is the IP rating on the E-32, and can it be used in wash-down environments?
A: The internal switch is rated IP67 (sealed against temporary submersion), and the EWP assembly carries an IP66 rating (protected against high-pressure water jets). This makes the E-32 suitable for wash-down zones and outdoor installations exposed to direct rain and cleaning spray. Verify your specific cleaning pressure and angle against the IP66 definition if the unit will face direct high-pressure washdown regularly.
Q: What is the operating temperature range of the E-32?
A: The E-32 is rated from -30°F to 170°F (-34°C to 77°C), covering unheated outdoor enclosures, cold storage entry points, and high-heat environments such as rooftop equipment rooms or sun-exposed exterior walls.
Q: How many phone numbers can the E-32 dialer be programmed to call?
A: The built-in dialer is programmable to call up to 5 numbers. This allows sequential or selectable ring-down to guard stations, backup desks, or management contacts without requiring an external auto-dialer or PBX hunt group configuration.
Q: Will the E-32 work with a VoIP or SIP phone system?
A: No — the E-32 is designed for analog POTS lines and analog PBX extensions only. For SIP/VoIP environments, Viking offers the E-32-IP, which is built for SIP VoIP phone systems with PoE.
Q: What is the warranty on the E-32?
A: Viking Electronics provides a two-year limited warranty on the E-32.
The E-32 is the unit I reach for when someone describes a location that has killed two or three other entry phones already — loading dock doors, outdoor stairwells at cold-storage facilities, coastal utility entries. The combination of 14-gauge 316 stainless, IP67-sealed internals, and a -30°F to 170°F operating range isn't marketing copy; it reflects what the device is actually engineered to survive. If you're specifying for a location with an analog line already run and no PoE infrastructure, the E-32 solves the problem without pulling a new power circuit.
Technical Highlights:
- Telephone Line Power (24V DC / 20mA minimum): No power conduit, no transformer, no outlet — if the analog line reaches the door, the unit runs. On long cable runs in large facilities, confirm loop current at the far end; 20mA at 24V DC is the floor, and voltage drop over distance is the most common commissioning issue.
- IP67 Internal Switch / IP66 EWP: The switch itself survives submersion; the enclosure assembly handles sustained high-pressure water jets. For food-processing or pharmaceutical entry points with regular chemical wash-downs, this is the relevant combination — IP66 alone covers most scenarios, and IP67 provides the backstop if water finds a seam during cleaning.
- 5-Number Programmable Dialer with Auto-Answer: The dialer sequences through up to five numbers, and auto-answer lets the far end open a listen-in or talk-down session without user action at the door. In correctional or secure-entry applications, that combination removes the requirement for a cooperative user at the terminal to initiate contact.
Deployment Considerations:
- The E-32 mounts into a standard double-gang box — a 4" × 4" × 2.12" plastic box is included. Confirm the rough-in box depth in your wall assembly before ordering; the unit itself is 5" × 5" × 2.25" overall and needs the specified minimum box dimensions (3.65"W × 2.84"H × 2.25"D) for proper seating and gasket compression.
- This is an analog-only device — 25VAC RMS minimum ring voltage, REN 0.5A. If the site has already migrated to SIP or hosted PBX, the E-32 will not register; spec the E-32-IP instead. Mixing analog and VoIP endpoints at the same facility is the scenario most likely to generate a support call on this product.
The E-32 is the correct specification for industrial and institutional analog entry points where the environment is genuinely hostile — not just 'outdoor rated' in the marketing sense, but sub-zero winters, chemical spray, and aggressive physical contact. Food processing plant entries, cold-storage dock doors, and coastal parking structures are the deployment scenarios where this unit's build quality justifies itself over cheaper alternatives inside of the first winter.
