Viking Electronics E-1600-GT-IPEWP VoIP Emergency Phone for GAI-Tronics Back Box
The Viking Electronics E-1600-GT-IPEWP is a SIP 2.0 VoIP emergency phone engineered as a direct physical replacement for GAI-Tronics Red Alert installations — letting you migrate aging analog emergency call points to an IP network without cutting new conduit or replacing back boxes. It flush-mounts into the existing GAI-Tronics enclosure and brings Enhanced Weather Protection (EWP) that pushes humidity tolerance to 100%, making it viable in wash-down zones, outdoor enclosures, and industrial environments where standard IP-rated phones wash out.
Overview
Facilities teams managing legacy GAI-Tronics ADA emergency phone infrastructure face a familiar constraint: the back boxes are already in the wall, the conduit runs are done, and ripping them out for a modern VoIP system is expensive. The E-1600-GT-IPEWP solves that directly — it drops into the existing GAI-Tronics back box (12.0 x 10.0 x 2.0 in. HxWxD flush-mount footprint), connects to your SIP call manager over a single VoIP network cable, and delivers ADA-compliant emergency calling with no structural rework. For facilities with dozens of stairwell, parking structure, or industrial-floor call points already roughed in, the per-unit labor savings are material.
Key Features
- Direct GAI-Tronics Physical Replacement: Sized and configured to flush-mount into the GAI-Tronics Red Alert back box — no new rough-in, no patching, no custom adapter plates. If you are converting a campus or facility with an existing GAI-Tronics footprint, this is the fastest path to SIP without construction cost.
- Enhanced Weather Protection (EWP) to 100% Humidity: Standard IP66 covers rain and dust ingress, but many industrial and outdoor-adjacent installations see condensation cycles that exceed that threshold. The EWP designation extends humidity tolerance to 100% non-condensing-to-condensing conditions — relevant for loading docks, covered parking, mechanical rooms, and coastal installations.
- IP66 Ingress Protection: Rated to withstand powerful water jets and total dust exclusion, so the unit survives hose-down cleaning cycles in food processing, manufacturing, and transit environments without requiring a secondary protective housing.
- PoE Class 1 Power (<4W): Draws under 4 watts from a standard 802.3af PoE switch port — well within Class 1 budget. That means a single CAT5e/6 run delivers both data and power, and the unit won't strain a mid-density PoE switch. No local power supply, no outlet hunting, no separate power conduit.
- 95 dB SPL at 1 Meter: Loud enough to be heard over ambient industrial noise or a busy parking structure without a separate amplified speaker. For environments with continuous background noise above 70–75 dB, 95 dB SPL at 1m gives roughly 20 dB of headroom — the difference between a call that gets answered and one that doesn't.
- SIP 2.0 RFC 3261 Compliance: Registers to any standards-compliant SIP call manager — Cisco Unified, Avaya, Asterisk, FreePBX, Microsoft Teams Direct Routing via SBC — without proprietary middleware. Your existing SIP PBX infrastructure handles routing, recording, and escalation logic.
- G.711u / G.711a / G.722 Audio Codecs: G.722 wideband audio (7 kHz) is worth noting for emergency use: speech intelligibility improves noticeably over G.711 narrowband in noisy environments, which matters when a caller is stressed and background noise is high. G.711u/a ensures compatibility with nearly every SIP platform that doesn't support wideband.
- 2-Amp Relay Contacts (30VDC / 125–250VAC): The onboard relay handles door strike, gate, or beacon control directly — up to 2A at 30VDC or 1A at 125VAC, 250VAC maximum. That lets a single unit serve as both the emergency call point and the access release trigger, eliminating a separate relay module in the back box.
- 3x Gel-Filled Butt Connectors: Field connections use gel-filled connectors rather than bare wire nuts, providing moisture-sealed terminations that resist corrosion — consistent with the EWP design philosophy and appropriate for outdoor or damp-location wiring.
- -40°F to 140°F Operating Range: Covers unheated parking structures in northern climates and sun-exposed outdoor enclosures in southern ones. Most VoIP endpoints rate to 32°F minimum — this unit operates 72°F colder, which matters for any installation that isn't climate-controlled year-round.
- CE / FCC Part 15 / Canada ICES-003 Class A Regulatory Compliance: Ships compliance-ready for US, Canadian, and EU deployments — no additional homologation work required for standard North American and European projects.
Integration and Compatibility
The E-1600-GT-IPEWP connects via a single RJ45 10/100BASE-TX port with auto-crossover, simplifying field wiring. It registers as a standard SIP 2.0 endpoint (RFC 3261), making it compatible with the full range of enterprise and hosted SIP call servers. The 100BASE-TX connection is sufficient for the G.722 wideband audio stream at well under 100 kbps, so it can share infrastructure with existing data drops where necessary. The relay output — rated at 2A/30VDC or 1A/125–250VAC — integrates directly with door hardware, motorized gates, or visual alerting devices, eliminating the need for a separate control module in most deployments. For sites already running access control systems, the relay contact can tie into an existing door controller input without additional interface hardware.
The automatic polling and programming software included with the Viking Electronics product line allows remote provisioning, which is relevant when deploying across multiple call points on a large campus — you provision once and push configuration rather than programming units individually at each location. For facilities considering a broader emergency phone deployment, the 1600-IP Series covers multiple back-box configurations beyond the GAI-Tronics footprint.
Frequently Asked Questions
Q: Is the E-1600-GT-IPEWP a true drop-in replacement for a GAI-Tronics Red Alert unit?
A: Yes. The E-1600-GT-IPEWP is documented as a direct physical replacement for GAI-Tronics Red Alert installations, designed to flush-mount into the existing GAI-Tronics back box (12.0 x 10.0 x 2.0 in.) without structural modification.
Q: Does the E-1600-GT-IPEWP require a separate power supply?
A: No. It draws power over the network cable via 802.3af PoE (Class 1, under 4 watts). A standard PoE switch port is all that is required — no local AC outlet or power injector is needed.
Q: What SIP platforms is the E-1600-GT-IPEWP compatible with?
A: It implements SIP 2.0 per RFC 3261, which is the industry standard. It is compatible with any standards-compliant SIP call server, including Cisco Unified Communications Manager, Avaya, Asterisk, FreePBX, and similar platforms. Proprietary middleware is not required.
Q: What does the Enhanced Weather Protection (EWP) designation mean in practice?
A: Standard IP66 covers rain and dust. The EWP rating extends humidity tolerance to 100% — including condensing conditions — making the unit appropriate for wash-down environments, outdoor enclosures subject to temperature cycling, and coastal or high-humidity industrial facilities where standard IP66 endpoints may corrode internally over time.
Q: What is the operating temperature range of the E-1600-GT-IPEWP?
A: -40°F to 140°F (-40°C to 60°C). This covers unheated parking structures, outdoor enclosures, and industrial facilities across most North American climate zones without supplemental heating or cooling.
Q: Can the relay output on the E-1600-GT-IPEWP control a door strike or electric gate?
A: Yes. The unit includes relay contacts rated at 2A at 30VDC or 1A at 125VAC (250VAC maximum), suitable for directly controlling most door strikes, magnetic locks, and motorized gate inputs without a separate relay module.
The spec I keep coming back to on the E-1600-GT-IPEWP is the -40°F cold-start rating combined with 100% humidity tolerance — that combination is genuinely uncommon in SIP emergency endpoints and it's what separates this unit from standard VoIP phones dressed up with an IP66 label. Most of the sites I see deploying this are converting multi-building campuses with existing GAI-Tronics infrastructure, where the back boxes are already in concrete stairwells and parking decks that see everything from -20°F Minnesota winters to summer condensation cycles.
Technical Highlights:
- 802.3af PoE Class 1 (<4W): At under 4 watts, you can run 24 of these off a single 100W PoE switch without approaching budget limits — relevant when wiring a multi-story parking structure where you want one IDF closet per floor serving 12–18 call points.
- 95 dB SPL at 1 Meter: That output level is enough to cut through a parking deck with active traffic (ambient typically 70–80 dB) with meaningful headroom. The difference between 85 dB and 95 dB is not subtle when a caller is yelling over a running engine.
- G.722 Wideband Audio: Emergency call intelligibility under stress and background noise improves measurably with 7 kHz wideband versus 3.4 kHz narrowband G.711. If your call manager supports G.722, enable it — the codec negotiation is automatic per the SIP stack.
Deployment Considerations:
- The flush-mount footprint is 12.0 x 10.0 x 2.0 in. (HxWxD) — verify your GAI-Tronics back box dimensions before ordering if you have mixed generations on site, as older Red Alert enclosures may differ slightly from current production.
- The relay contacts are rated at 2A/30VDC maximum — confirm your door strike or gate controller draw is within spec before wiring direct. Heavier loads (high-current magnetic locks) will need an interposing relay.
This unit is the right call for university campuses, transit authority facilities, and large industrial plants that are mid-cycle on a GAI-Tronics analog infrastructure replacement — where the back boxes are sunk costs and the goal is SIP migration without a construction budget.
