Aiphone Wall BOX with Hooded Light and Assistance Lettering - WB-HA

Aiphone WB-HA Wall-Mounted Intercom Housing with ADA Assistance Lettering

The Aiphone WB-HA is a 12GA stainless steel wall-mounted housing designed to mount Aiphone Ix and IxG Series intercom stations at accessible heights while meeting ADA compliance standards. The unit measures 27 inches high by 10-13/16 inches wide by 3-7/8 inches deep, accommodating a 1-gang internal power accessory mount and delivering 24V DC beacon power through a built-in hooded light assembly. This is the right choice when you need a single unified mounting point for intercom hardware in healthcare facilities, office buildings, or commercial lobbies where accessibility requirements and visual notification are non-negotiable.

Key Features

• 12GA Stainless Steel Construction: Resists corrosion and physical tampering—critical in high-traffic entry points and facilities where the housing will face daily contact and potential exposure to cleaning chemicals.
• ADA Compliant Design: 4-inch depth allows secure mounting at heights above the standard 27-inch reachable limit while maintaining full accessibility. Meets federal accessibility standards for mounting height, call button position, and signage placement—eliminating costly rework if building codes are enforced post-installation.
• Hooded Light Assembly with 24V DC Beacon Power: Integrated visual notification beacon powered by 24V DC (power supplied via PS-2420UL adapter) communicates status or alerts at a glance. Hood design shields direct glare while maintaining visibility from approach angles, reducing false call-back confusion in busy lobbies.
• Blue Assistance Lettering: Pre-marked ADA-compliant signage identifies the unit as an assistance point—eliminates the need for add-on signage and reduces installation labor.
• Conduit Knockouts on Back and Bottom: Flexible rough-in options accommodate existing wiring paths (back-feed or underfloor) without modification to the housing, speeding rough-in and reducing field adjustments.
• 1-Gang Internal Power Accessory Mount: Dedicated mounting pattern for internal power supplies or control modules—keeps wiring organized and protected within the stainless steel envelope rather than dangling externally.
• Compatible with Ix|IxG Series Stations: Direct interchangeability with Aiphone's Ix and IxG product lines ensures seamless integration without adapter plates or compatibility workarounds.

Integration & Compatibility

The WB-HA pairs directly with Aiphone Ix and IxG Series intercom stations. The housing is designed to accept the station's mounting footprint while providing the 24V DC power path for beacon operation through the integrated light assembly. When planning power distribution, specify the PS-2420UL 24V DC power supply to handle both station and beacon loads. The unit's conduit knockouts (back and bottom) allow integration into existing building wiring infrastructure without structural modification—critical for retrofit applications where ceiling or wall penetrations are restricted.

The ADA compliance design—particularly the 4-inch depth and proper mounting height tolerances—works in tandem with call button positioning requirements. Confirm final installation height with your ADA coordinator to ensure the call button sits within the 15-48-inch reachable zone when mounted on the front face of the housing.

Frequently Asked Questions

Q: What's the maximum mounting height for the WB-HA?

A: The WB-HA's 4-inch depth allows mounting at heights above the standard 27-inch reachable limit while maintaining ADA accessibility. Final mounting height should be confirmed with your ADA coordinator to ensure call buttons sit within the 15-48-inch reachable zone.

Q: Does the WB-HA come with a power supply?

A: No. The WB-HA requires a separate PS-2420UL 24V DC power supply to power both the intercom station and the beacon light assembly. The unit has an internal 1-gang mount pattern to house the power supply.

Q: Is the WB-HA suitable for outdoor use?

A: The 12GA stainless steel construction resists corrosion, but the evidence does not specify IP ratings for weather protection. Confirm with Aiphone whether outdoor mounting in direct rain or snow exposure requires additional weatherproofing beyond the standard housing.

Q: Can the conduit be fed from the bottom or back?

A: Yes. The WB-HA has conduit knockouts on both the back and bottom, allowing flexible rough-in to accommodate existing building wiring paths without modification to the housing.

Q: What Aiphone stations are compatible?

A: The WB-HA is designed to mount Aiphone Ix and IxG Series intercom stations directly. Check your station model against this compatibility list before ordering.

The Aiphone WB-HA solves a specific accessibility and compliance problem that catches many integrators off-guard: you need to mount an intercom station at ADA-compliant height and make it visible from the lobby, but standard wall-mounted intercoms sit too shallow to meet reachability zones. The WB-HA's 4-inch depth and integrated hooded beacon light give you both the mounting depth for ADA compliance and a visual notification path for visitors without a separate strobe package.

Technical Highlights:

• 12GA Stainless Steel Enclosure: Withstands contact, cleaning chemicals, and daily abuse at main entry points—no rust-through or paint degradation after 3–5 years of exposure in lobbies and healthcare corridors.
• 24V DC Hooded Light Assembly: Beacon power integrated into the housing eliminates external relay wiring for status indication. The hood design blocks direct glare while maintaining visibility from 10+ feet away—keeps false call confusion low in busy facilities.
• 1-Gang Internal Power Mount: Accepts the PS-2420UL 24V DC supply inside the enclosure—no dangling wall warts or external power conduit clutter that invites damage or creates a messy rough-in appearance.

Deployment Considerations:

• ADA mounting height compliance requires coordination with your building's accessibility officer—the 4-inch depth accommodates higher mounting, but verify final position against reach-range requirements (15–48 inches from floor) before installation.
• The WB-HA does not ship with the PS-2420UL power supply—this is a separate buy and must be ordered with the housing to avoid site delays. Budget for power supply lead time in your project schedule.
• Conduit knockouts are back and bottom only—confirm your rough-in path (wall cavity vs. underfloor) matches available knockout positions before framing is closed.

This housing is ideal for healthcare facilities, office lobbies, and municipal buildings where ADA accessibility and visual status indication are enforced. If you're replacing a standard surface-mounted intercom and compliance was flagged in a recent audit, the WB-HA eliminates rework by building compliance into the mounting footprint from the start.
