Viking Electronics E-1600A-RTM-EWP ADA Emergency Phone for Ramtel Applications

The Viking Electronics E-1600A-RTM-EWP is a telephone-line-powered ADA-compliant emergency phone built for demanding outdoor and industrial installations — specifically engineered to flush-mount into Ramtel columns, towers, wall mounts, and 924/904 boxes. At 6.50" x 8.50" x 2.0", it fits the Ramtel Mini footprint cleanly while delivering the environmental resilience — IP66, 100% humidity tolerance, and a -30°F to 170°F operating range — that mass-transit platforms, parking structures, and industrial campuses actually need. If you're speccing emergency call stations for Ramtel infrastructure, the E-1600A-RTM-EWP is purpose-built for exactly that application.

Overview

The E-1600A-RTM-EWP belongs to Viking's 1600A Series, a line designed around reliable, no-frills emergency communication. The phone draws power entirely from the telephone line — no separate power run, no transformer, no local supply to fail. It requires a minimum 24V DC talk battery voltage and 20mA loop current from the connected line equipment, which is standard for any properly provisioned analog emergency line. The enclosure is 14-gauge Marine Grade 316 stainless steel: the alloy that handles coastal salt air, industrial chemical wash-downs, and UV exposure over a multi-decade service life without pitting or structural compromise. Optional Enhanced Weather Protection (EWP) — included in this model — adds foam rubber gaskets and sealed connections specifically to meet IP66 ingress standards. The result is a station that won't fail because condensation worked its way into a connector.

Key Features

• Telephone Line Powered (24V DC / 20mA minimum): No local power infrastructure required. The phone draws everything it needs from the loop — reducing installation complexity and eliminating a common failure point in outdoor call-station deployments. As long as the telco line is live, the station is live.
• IP66 Enhanced Weather Protection: IP66 means sustained water jets from any direction won't penetrate the enclosure. The EWP designation adds foam rubber gaskets and sealed connections beyond the standard enclosure — relevant in environments with pressure wash-downs or driving rain. Not rated for submersion; if below-grade or flood-prone installation is planned, a higher IP-class product is required.
• Marine Grade 316 Stainless Steel, 14-Gauge: 316 stainless is the standard for coastal and chemically aggressive environments where 304 stainless pits. At 14-gauge, the enclosure resists vandalism loads and physical impact without deforming. This isn't cosmetic stainless — it's structural.
• Operating Temperature -30°F to 170°F (-34°C to 77°C): That range covers virtually every North American outdoor installation, from northern Minnesota parking ramps in January to exposed desert rooftop enclosures in August. Most competing stations top out at 140°F; the 170°F ceiling matters in direct-sun enclosures without ventilation.
• Up to 100% Humidity Tolerance: Rated for full saturation — relevant for car wash bays, covered but open transit platforms, and coastal marine environments where standard electronics corrode within months.
• ADA Compliant: Meets ADA requirements for emergency communication devices, which is a non-negotiable specification for public-access installations in the US. Confirm local jurisdiction requirements for mounting height and reach-range compliance during rough-in.
• Flush Mount for Ramtel Infrastructure: Designed specifically to flush-mount to Ramtel Mini columns, towers, wall mounts, 924 and 904 boxes — no adapter plates, no custom fab. If your project is Ramtel-based, this eliminates the fit-up issues that come with generic phone hardware.
• Compact Form Factor (6.50" x 8.50" x 2.0"): The Ramtel Mini footprint keeps the station unobtrusive on columns and towers where physical profile matters. Shipping weight is 2.8 lbs — light enough for single-person installation on overhead or elevated Ramtel mounts.

Integration and Compatibility

The E-1600A-RTM-EWP operates on a standard analog telephone loop. It integrates with Viking's optional BLK-4 Control Module, which accepts 120V AC input and provides a 12V DC / 500mA output — useful when local power is available and additional control functions are needed at the station. The phone's signal requirements (minimum -22 dBm signal level, 7 busy pulses minimum, 300–2000 Hz frequency range, 450–550ms ON/OFF timing) are compatible with standard analog PSTN and analog PBX/PABX line equipment. No proprietary line card or VoIP gateway is required for basic operation, though SIP-to-analog adapters can be used to connect to IP-based dispatch systems if the project requires it. Verify loop current delivery at the farthest station when designing multi-station emergency call systems — the 20mA minimum is a hard floor, not a guideline.

Frequently Asked Questions

Q: What mounting infrastructure does the E-1600A-RTM-EWP require?

A: The E-1600A-RTM-EWP is designed to flush-mount specifically to Ramtel Mini columns, towers, wall mounts, and 924/904 boxes. It is not a surface-mount or standalone unit — Ramtel back box infrastructure is required.

Q: Does the E-1600A-RTM-EWP require a separate power supply?

A: No. The phone is telephone line powered, requiring a minimum 24V DC talk battery voltage and 20mA loop current from the connected line equipment. The optional BLK-4 Control Module (120V AC input, 12V DC/500mA output) is available if additional local power functions are needed, but is not required for basic operation.

Q: What is the IP rating on the E-1600A-RTM-EWP?

A: The E-1600A-RTM-EWP carries an IP66 rating through its Enhanced Weather Protection (EWP) package, which includes foam rubber gaskets and sealed connections. IP66 protects against sustained water jets from any direction but does not cover submersion.

Q: What temperature range is the E-1600A-RTM-EWP rated for?

A: Operating temperature is -30°F to 170°F. This covers the full range of North American outdoor deployments, including high-sun enclosures where interior temperatures can exceed 140°F.

Q: What material is the enclosure?

A: The enclosure is 14-gauge Marine Grade 316 stainless steel — the same alloy used in coastal and chemically aggressive environments where standard 304 stainless is insufficient.

Q: Is the E-1600A-RTM-EWP ADA compliant?

A: Yes. The E-1600A-RTM-EWP is ADA compliant for emergency communication applications. Verify mounting height and reach-range compliance with local jurisdiction requirements during installation.
