Viking Electronics E-1600-52A-EWP Emergency Phone Parts Kit with Enhanced Weather Protection

Overview

The E-1600-52A-EWP is a replacement parts kit for Viking's 1600A Series analog emergency phone line — designed specifically for field repair and component-level servicing rather than full unit replacement. It includes a circuit board, two buttons (EMERGENCY and INFO), a speaker, and a wire harness, all built to the Enhanced Weather Protection (EWP) standard. That EWP rating means the internal components are sealed for environments with up to 100% relative humidity, making this the correct service kit for outdoor installations, covered parking structures, elevator lobbies exposed to weather ingress, or any coastal or high-condensation deployment where a standard-humidity replacement kit would degrade prematurely. The unit is telephone line powered — no batteries, no external supply — requiring a minimum 24V DC talk battery and 20mA loop current from the connected analog line.

Compatibility

Designed for the Viking 1600A Series emergency telephone platform, specifically servicing the E-1600-52A model — a two-button, handsfree, ADA-compliant analog emergency phone compatible with standard Central Station Monitoring equipment. The two-button configuration (EMERGENCY + INFO) supports dialing up to three non-emergency numbers from the INFO button in addition to the primary emergency contact. This kit is appropriate for any E-1600-52A unit deployed on a standard PSTN or analog telephone line. It is not intended for the 1600-IP Series VoIP platform or the E-1600A-BLT-EWP tower model, which use different internal assemblies.

Installation Notes

The EWP wire harness is rated for continuous exposure up to 100% humidity — a meaningful upgrade over standard 5%–95% non-condensing limits. Operating temperature range extends from -30°F to 170°F, covering most North American outdoor installations year-round. The E-1600A Series enclosure it services measures 5.25
