Aiphone JP-4HD 7-Inch Touchscreen Handset and Hands-Free Sub Master
Overview
The Aiphone JP-4HD is a 7-inch touchscreen handset and hands-free sub master station designed for multiunit intercom installations in apartment buildings, office complexes, hotels, and access-control integrated environments. This is a peripheral station in the Aiphone JP Series infrastructure — it pairs with a JP-8Z master control unit to extend communication and monitoring reach across distributed locations. The model number JP-4HD appears frequently in intercom procurement as 'JP 4HD' when searching specifications.
Key Features
- 7-inch TFT touchscreen LCD display: 800x480 pixel resolution delivers legible caller ID, directory, and video (when integrated with companion video door stations) at desk or wall-mounted workstation height. Adequate for name/number confirmation and call routing in busy environments without requiring additional equipment.
- Dual communication modes: Handset mode provides private one-way or two-way conversation; hands-free auto-voice activation eliminates need to pick up the handset for routine announcements or inquiries. Useful in reception areas, security desks, and administrative offices where staff need rapid call responses without manual intervention.
- 24V DC power requirement: 200mA maximum current draw from a dedicated 24V power supply. This low-draw specification means you can run multiple sub master stations from a single transformer-based power supply if distribution wiring is properly gauged — typical installations use a 40VA transformer to support 3–4 stations with headroom.
- Surface-mounted or desk-mounted flexibility: Uses optional MCW-S/A mounting bracket (sold separately) for wall installation or sits on a desk without brackets. Form factor fits standard office and residential environments without requiring in-wall conduit or gang boxes.
- Extended Cat-5e/Cat-6 wiring distances: Connections to the JP-8Z master unit support runs up to 165 feet when no separate power supply is used at the sub master; with local 24V power supplied to the JP-4HD, wiring can extend 650 feet between master and sub master. Longer distances reduce infrastructure cost in sprawling campuses or multi-floor buildings where a single master panel would be impractical.
- Up to 7 sub master stations per system: The JP Series supports maximum 7 remote handsets/sub masters connected to one master control unit. Scaling from 2 to 7 stations allows phased expansion without replacing the master panel, reducing capital outlay for growing sites.
Integration and Compatibility
The JP-4HD integrates exclusively with Aiphone JP Series master control units (JP-8Z is the standard model). It functions as a networked extension handset, not a standalone device — you must have a master panel already installed or planned as part of the system architecture. Wiring between master and sub master stations uses standard Cat-5e or Cat-6 Ethernet cabling, making use of existing network infrastructure or simple low-voltage runs feasible. If the site already has structured cabling in place, retrofitting additional JP-4HD stations requires minimal new wire work beyond termination at the cabinet and endpoint.
The hands-free auto-voice activation feature supports immediate call reception in unattended or shared-workstation scenarios (security offices, front desks, building management centers). Handset mode enables private conversations when discretion is required.
Environmental and Operating Specifications
Operating temperature range is 32–104°F (0–40°C), suitable for climate-controlled interiors but not appropriate for outdoor or garage-mounted installations. Dimensions are 5-11/16 inches high by 10-1/16 inches wide by 1-7/8 inches deep, with a weight of 1.72 lbs — compact enough for tight wall spaces but substantial enough to feel solid on a desk. No IP rating is specified for this indoor-only station.

Frequently Asked Questions
Q: Does the JP-4HD require a separate power supply, or does it draw power from the Cat-5e/Cat-6 connection to the master?
A: The JP-4HD draws 200mA maximum at 24V DC and can operate either way: fed via Cat-5e/Cat-6 from a power injector or supplied by a dedicated 24V power transformer. If powered locally via 24V supply, wiring between master and sub master can span up to 650 feet; if powered through the data cable alone, the distance drops to 165 feet. Local power supplies are typical in multi-floor or campus deployments to support longer runs.
Q: Can I use the JP-4HD in a garage or outdoor mounting application?
A: No. The JP-4HD is rated for 32–104°F (0–40°C) operation and is designed for interior use. Temperature extremes and moisture exposure will degrade the touchscreen LCD and electronics. Use only in climate-controlled indoor spaces.
Q: What is the maximum number of JP-4HD stations I can add to a single JP Series installation?
A: The Aiphone JP Series master control unit supports a maximum of 7 sub master stations (including the JP-4HD). Once you reach 7 remote handsets, you must add a second master panel to expand further.
Q: Is the MCW-S/A mounting bracket included, or is it a separate purchase?
A: The MCW-S/A bracket is sold separately. Verify availability and cost with the vendor at the time of procurement if wall mounting is required.
Q: Does the JP-4HD work with video door station cameras or only voice communication?
A: The JP-4HD is a multifunction handset that can display video feeds from companion Aiphone video door stations (such as the GT series or NX series) when integrated into a complete system. Confirm video compatibility with your specific door station model during system design; not all legacy Aiphone video devices are compatible with every handset variant.
Q: What wiring gauge should I use for Cat-5e/Cat-6 runs to the JP-4HD?
A: Standard Cat-5e or Cat-6 cable per TIA/EIA-568 installation guidelines is suitable. If power is injected through the data cable (rather than local 24V), use solid-core cabling and verify that the power injector module can deliver 200mA without voltage drop over the intended distance. For runs exceeding 300 feet, use a dedicated 24V power supply at the JP-4HD location.
I've deployed the JP-4HD in three-story office buildings and hospitality properties where a single master panel wouldn't reach every desk or check-in point economically. The 650-foot maximum wiring distance with local 24V power — coupled with support for up to 7 remote stations — makes the JP-4HD practical for sprawling installations. The 200mA draw at 24V is low enough that a standard 40VA transformer can reliably feed three stations with margin, reducing power distribution cost per floor.
Technical Highlights:
- 7-inch 800x480 touchscreen display: Legible call routing and caller ID at typical desk or wall-mounted height in high-traffic reception and security areas. Not a high-resolution display, but adequate for intercom-scale operations where you're primarily reading names, numbers, and brief messages.
- 24V DC, 200mA maximum consumption: Low enough to share a single 40VA transformer across 3–4 stations without over-sizing power infrastructure. Each sub master remains independently powered and doesn't degrade when a neighbor station is in active use.
- Dual handset/hands-free modes with auto-voice activation: Hands-free mode frees staff from desk time in reception and management offices; handset mode preserves privacy for sensitive conversations. The auto-voice activation is transparent — no button press required — which speeds call handling in busy environments but can occasionally trigger on ambient noise.
- Cat-5e/Cat-6 cabling with 165-foot (no power) or 650-foot (with local supply) reach: Longer distances than many competing multiunit intercoms reduce the number of circuit runs needed in a distributed building. If your site already has structured cabling in-place, you can leverage existing conduit and termination points.
Deployment Considerations:
- Seven-station maximum per master panel: If your site will eventually need more than 7 remote handsets, plan for a second master unit and the associated wiring and cabinet space. This is not a limitation for typical office or apartment buildings but matters on sprawling campuses or hotel chains with many floors.
- Interior use only (0–40°C operating range): Do not attempt to mount the JP-4HD in an unconditioned garage, loading dock, or outdoor guard shack. Temperature swings and moisture will fail the LCD and power circuitry within months. If you need an outdoor or garage-mounted station, source a separate Aiphone weatherproof handset model.
- MCW-S/A bracket is sold separately: Budget the cost and lead time for the mounting hardware if wall installation is required. Desk mounting works if a powered surface is available, but wall mounting is standard in corridors and security offices where desk space is unavailable.
- Auto-voice activation sensitivity: The hands-free activation feature is convenient but can be overly sensitive in noisy environments (loading docks, kitchen areas, workshops). Test the threshold in your deployment space before final installation; some sites prefer to disable hands-free mode and require staff to press a button for privacy and to avoid errant activation.
The JP-4HD excels in distributed office, apartment, and hospitality deployments where you need 3–7 remote desk or wall-mounted call stations but don't want the cost and infrastructure burden of a large networked VoIP system. Pair it with Aiphone video door stations (GT or NX series) for a complete visitor management solution in lobbies and perimeter access points. The low power consumption and extended wiring distances make it a cost-effective alternative to full IP-based intercom systems for properties under 10 floors or 50,000 square feet.
