Platform service
Elwin Security repairs and replaces Zenitel intercom stations at Bay Area multifamily and commercial properties. That covers the Turbine Compact TCIV+ and TCIS stations, the TEIV-1+ and TEIV-4+ door stations, the ZDD-1 and the Zenitel Slim Door ZSD-1.
Use case
A dead station, a discontinued model and an entry that has outgrown its station each have a different fix.
Zenitel's Turbine start-up page says to connect the LAN port of the device to a PoE port on the network switch. When the switch, the cable or the server registration is the cause, the fix is at the network, not in the panel.
Zenitel's wiki marks the TCIV-3 and TCIV-6 as discontinued and names the TCIV-3+ and TCIV-6+ as their replacements. The ITSV-1, ITSV-2 and ITSV-3 indoor stations are discontinued, with the ITSV-1 replaced by the ITSV-2, the ITSV-2 by the ITSV-4 and the ITSV-3 by the ITSV-5.
Zenitel's door entry brochure (2025.04) describes the TEIV-1+ as a keypad door station with display and scroll for multi-tenant visitor solutions, and the TEIV-4+ as a one-button station with mechanical space for a third-party card reader inside the intercom.
Service focus
The first job is to identify the model, the item number, the platform it registers to and the shipment date.
Elwin configures the mode to match the server the station registers to: Zenitel Connect Pro, ICX-AlphaCom, IC-Edge or SIP.
Zenitel's Turbine+ board connectors page lists the SPDT relay contact at a maximum of 250 VAC or 220 VDC, 2 A and 60 W. Elwin tests the PoE source, the cable run, the relay contact and the strike or maglock power supply before replacing a station.
Zenitel USA's terms and conditions (Rev. September 2026) warrant each Zenitel Product for 36 months from the shipment date, under normal use. Where the return time or the repair cost does not make sense, Elwin replaces the station with the Zenitel model the wiki names as its replacement or with another video intercom.
Service check
A Zenitel label on the front plate is not enough. The item number, the PoE class at the switch, the mode the station runs in and the shipment date decide which Zenitel procedure, part or return path applies.
Which relay drives which door or gate, where the strike or maglock supply comes from, and the shipment date.
Scope details
The front plate is what visitors see. The board behind it, the PoE path, the relay and the server it registers to are what a repair touches.
Zenitel's TCIV+ product sheet lists the TCIV-2+ with a stainless steel front plate and the TCIV-3+ with a black thermoplastic front plate. The TEIV-4+ (1008318240) product page lists options for wall or flush mounting. The ZSD-1 (1008325010) is mullion-mounted at 197 x 48 x 31 mm, and the ZDD-1 (1008510101) measures 281 x 176 x 44.5 mm.
The TCIV-3+ and TEIV-1+ product pages list IEEE 802.3af and 802.3at PoE with 3.5 W idle and 12 W maximum draw. The ZDD-1 product page lists 802.3bt Type 3 Class 6 (51 W), maximum power consumption of 30 W and 2 x RJ45.
The TCIV-3+, TEIV-1+ and TEIV-4+ product pages list a change-over relay (NO+NC+COM); the TEIV pages rate it 2A, 60W, SELV. Where a Zenitel relay releases a maglock or an exit door, the fire marshal or local AHJ decides what egress hardware is acceptable.
The TCIV-3+ wiki page lists four modes: Zenitel Connect Pro, ICX-AlphaCom, IC-Edge and SIP.
Process
Elwin ties repair decisions to Zenitel's published data sheets, wiki pages, release notes and terms of sale.
Record the model, item number, PoE source, cable run, mode and relay wiring. Test the call, the camera stream and the release at the panel.
Result: The quote names the exact Zenitel procedure, firmware version, part, factory return or replacement model, not a generic intercom repair.
Match the failure to Zenitel's release notes and security advisory, its warranty terms, or the replacement model its wiki names.
Result: The property knows what the fix costs and what it leaves in place.
Mount a Turbine Compact station on the TA-1 on-wall box or the TA-5 bracket, set the mode and test each relay.
Result: The entry works and the property can see how its station is configured.
Field proof
Zenitel's support page, terms and conditions and wiki state its spare parts, warranty and discontinuation notices.
Zenitel's support page states that it offers spare parts up to 10 years after a system was purchased, and its general terms of sale (March 2026) warrant the availability of spare parts, meaning any item listed in the current Zenitel spare part price list.
Zenitel USA's terms and conditions (Rev. September 2026) give a 36-month warranty from the shipment date, with repair or replacement at Zenitel's option as the sole remedy, and state that the warranty is afforded only to the Buyer and is not a warranty to the Buyer's customers.
Zenitel's general terms (March 2026) require the Buyer to uninstall a defective product returned to the factory and reinstall it after repair or replacement, and state that for a repair done on site, Zenitel approves the company or technician doing the labour on its behalf.
A surface closer, a frame-mounted sensor, a cable-fed lock and a wall keypad at a mesh entry door.
A wooden slat pedestrian gate with a surface-mounted closer arm across the top rail.
Zenitel's wiki names the TCIV-3+ as the replacement for the TCIV-3. Zenitel's TCIV+ product sheet states that the TCIV+ packs HD video technology within the same form factor as the Turbine Compact (TCIS) range. The TCIV-3+ wiki page lists the TA-1 on-wall box and the TA-5 bracket for US 2-gang back boxes; Elwin checks the existing box first.
Service request
Tell Elwin what is not working, what systems are already on site, and which access points matter most. The next step is a scope grounded in the building, not a generic product list.
