Aiphone JVS-1F Flush Mount Door Station
The Aiphone JVS-1F is a 7-inch surface-mounted door station designed for multi-unit residential and commercial intercom installations where hands-free or push-to-talk communication is required at entry points. This unit integrates into Aiphone's JV series architecture, connecting master stations and expansion stations across wire runs up to 330 feet — depending on gauge — to centralize visitor screening and door access control.
Overview
The JVS-1F (often searched as JVS 1F) is a flush-mount door station with a 7-inch TFT LCD display, operating on 24V DC power drawn from a dedicated PS-2420UL power supply. It mounts in a standard 3-gang electrical box, using flame-resistant polycarbonate and ABS resin construction rated for indoor environments (32–140°F operating range). The unit measures 5-1/8 inches wide by 9-1/16 inches tall with a minimal 3/16-inch depth, making it suitable for applications where wall real estate is constrained or aesthetic integration is a priority.
Key Features
- 7-inch TFT LCD display: Bright, color video display for real-time visitor identification and two-way conversation initiation. Size sufficient for legible caller identification without requiring a separate video monitor at the door station itself.
- Hands-free VOX mode or push-to-talk: VOX (voice-operated exchange) eliminates manual button pressing for routine interactions; push-to-talk option available for environments where hands-free operation causes false triggers or privacy concerns.
- Dry contact door release output (N/O, 1A @ 24V AC/DC): Low-power relay contact directly drives electromagnetic locks or buzzer circuits without intermediate relay modules — simplifies wiring in small access control installations.
- Option output (N/O, 1A @ 24V AC/DC): Secondary relay contact triggers auxiliary devices (gate opener, light, siren) from the same station, reducing junction box complexity in multi-function entry scenarios.
- Request-to-exit dry contact input: Accepts N/O contact closure from exit buttons or motion sensors, enabling hands-free door release or integration with push-button-initiated unlock sequences on the master side.
- Wiring distance: 165 feet (22 AWG) or 330 feet (18 AWG): Copper gauge flexibility accommodates site constraints; larger gauge maintains signal integrity on longer runs, critical when master/expansion stations are remote from the entry point. Voltage drop across cable is the limiting factor, not distance alone.
- 24V DC single power source (PS-2420UL required): One power supply services the entire JV series network; draws 100 mA standby and 780 mA max under peak audio/video load, allowing budget calculation for backup battery or UPS sizing in access control designs.
- Flame-resistant PC + ABS enclosure: Meets material safety standards in commercial/multifamily installations; not UV-stabilized, so avoid prolonged direct sunlight outdoors or behind south-facing glass.
Integration & Compatibility
The JVS-1F operates as a slave device within an Aiphone JV series system architecture. It connects to a master station (typically an Aiphone JO-1MD or similar) via a 2-wire twisted pair at distances up to 330 feet. Expansion stations extend the network topology, allowing multiple door stations to report to a single master or distributed group of masters. The unit does not support ONVIF, SIP, or modern VoIP protocols — it is purpose-built for closed, self-contained intercom networks and cannot integrate with modern unified communications systems or third-party VMS platforms without gateway intervention (which is outside the scope of the base JVS-1F).
The dry contact relay outputs (door release and option) are rated for resistive loads only; do not switch inductive loads (solenoid locks, motors) directly without an intermediate relay or snubber diode to protect the internal switching circuitry.

Frequently Asked Questions
Q: Can the JVS-1F be mounted outdoors?
A: The JVS-1F is rated for indoor use only (32–140°F operating range, no IP rating provided). For outdoor entry points, you will need an outdoor-rated Aiphone door station such as the JO-1MD or a weatherproof enclosure, which is outside the intended deployment of this model.
Q: What power supply does the JVS-1F require?
A: The JVS-1F requires the Aiphone PS-2420UL 24V DC power supply. The unit draws 100 mA on standby and up to 780 mA under peak load; calculate total system draw if operating multiple stations before selecting backup power capacity.
Q: How far can the JVS-1F be wired from the master station?
A: Maximum distance is 165 feet using 22 AWG cable or 330 feet using 18 AWG cable, assuming a single interconnection. Voltage drop across the cable length determines practical limit; consult the wiring diagram in the Aiphone JV series manual for your specific configuration.
Q: Does the JVS-1F support SIP or VoIP integration?
A: No. The JVS-1F operates only within proprietary Aiphone JV series networks using analog signaling over twisted pair. It does not support ONVIF, SIP, or modern IP protocols.
Q: Can I use the JVS-1F's relay outputs to trigger a solenoid lock directly?
A: The dry contact relay is rated for 1A resistive load only. Solenoid locks are inductive and require an intermediate relay or snubber diode protection to avoid arcing and internal circuit damage. Do not switch inductive loads directly from the JVS-1F.
Q: Is the JVS-1F NDAA Section 889 compliant?
A: No compliance certification is stated in the available technical documentation for this model. If NDAA compliance is a requirement, confirm directly with Aiphone or your reseller before procurement.
The Aiphone JVS-1F is a solid choice for multi-unit residential and light commercial intercom retrofits where you need a compact, flush-mount door station with integrated video display and don't require IP networking or modern VoIP stack. The 7-inch TFT display and dual communication modes (hands-free VOX plus push-to-talk) cover most access screening scenarios, and the 1A dry contact relay outputs let you trigger buzzer releases or gate openers without cascading relay boards. The JVS-1F model is built around the constraint that it's a closed-system device — all networking happens over a single twisted pair, limited to 330 feet maximum run length depending on cable gauge.
Technical Highlights:
- 24V DC single supply (PS-2420UL): 100 mA standby, 780 mA peak load draw — sized budget for small UPS backup or transformer capacity; no second power rail to manage.
- Wiring distance up to 330 feet (18 AWG): Acceptable for campus-style multifamily or office building entry clusters; voltage drop is your real limit, not distance itself. Larger wire gauge necessary on longer runs.
- Dual dry contact relay outputs (1A each @ 24V AC/DC): Door release output plus optional auxiliary output — enough for buzzer or light trigger but not high-current solenoid locks; inductive loads require snubber protection.
- Hands-free VOX or push-to-talk communication: VOX works well in quiet lobbies; push-to-talk preferred in high-ambient-noise loading docks or mechanical rooms where false triggers are an issue.
Deployment Considerations:
- Indoor only (32–140°F): no IP rating, no UV stabilization. Avoid direct sun exposure or outdoor mounting; this is a vestibule/lobby device.
- Closed system architecture: The JVS-1F does not bridge to ONVIF, Milestone, or modern VMS platforms. If you need intercom + security camera integration on the same infrastructure, plan a separate system or gateway.
- Relay contact load rating is resistive only; solenoid locks are inductive and must use an intermediate relay to avoid contact arcing and circuit degradation over time.
The JVS-1F is purpose-built for traditional analog intercom networks in controlled indoor environments — apartment lobbies, office building entries, or small commercial access points. If your project demands outdoor exposure, IP networking, or integration with modern video management, step up to an IP-based intercom or hybrid solution.
