Aiphone JOS-1F - Entry Security Intercom Box Set with Vandal Resistant, Flush Mount Door Station, 7" Touchscreen (JO-DVF, JO-1MD, PS-1820UL)

The JOS-1F ships as a complete one-door system: the JO-DVF vandal resistant flush mount door station, the JO-1MD 7 inch inside master station, and the PS-1820UL power supply. What isn't in the box is wire. Aiphone calls for 2-conductor, low capacitance, non-shielded cable (their #871802), and if you're driving a lock you'll need the strike or maglock and, on anything past a small draw, an RY-18L relay. Everything else to talk to the door and see who's there is included.

Wire gauge sets the limit. From the door station to the farthest master station you get 165 feet on 22AWG and 330 feet on 18AWG. That's the run length, not the straight-line distance, so count the vertical drop and any conduit detours. On a two-story building or a long lobby-to-office pull, go 18AWG from the start. Cable is 2-conductor, low capacitance, non-shielded (Aiphone #871802).

Yes, there's a door release built in. It's a normally open dry contact rated 24V AC/DC at 500mA. That handles most low-current electric strikes directly. A maglock, a higher-draw strike, or anything running at a different voltage needs to go through an RY-18L relay rather than off the station contact. Wire the lock power separately; the contact is switching only, it doesn't source power to the lock.

One door and up to two inside stations. That's the ceiling on the JO Series, so it suits a single main entrance with a monitor at the front desk and a second in a back office. The JOS-1F set ships with one inside station, so a second monitor is a separate add. Note that the JO-DVF door station in this set is not sold on its own, so if you ever want a second door position the part to order is the JO-DV. Buildings with several entrances or more than two answering points have outgrown this platform.

The JOS-1F uses the JO-DVF, a flush mount station, which means it sets into the wall and needs a back box cut into the substrate. That's the choice for new construction, a masonry or drywall entry where you can open the wall, and anywhere you want the station sitting close to the face for a cleaner look and less to grab. If you're mounting to a finished wall you don't want to cut, to a narrow entry column, or to glass or metal storefront framing you can't recess into, a surface mount door station is the easier install. Decide that before ordering, because the two aren't interchangeable once the wall is closed up.

The camera is a 1/4 inch CMOS covering 2 feet 1 inch vertical by 3 feet 1 inch horizontal at a 20 inch distance. In practice that frames a face and shoulders of one person standing at the station, not the whole vestibule or a group behind them. If you need to see a delivery cart, a second person hanging back, or a vehicle, this is a visitor identification camera and not a surveillance camera. Mounting height matters more than usual with a field that tight, so set it for the face of an average adult standing at the door.

It's classed as commercial. The door station is the vandal resistant version, which is why the set exists as a separate part number from the standard JO door station, and that matters at a tenant entrance, a school door, a multi-family lobby, or any opening where the station is reachable from a public sidewalk. Property managers running a small building can absolutely use it, but the hardware is specified for a public-facing entrance rather than a private front door.

No, and this is the one that catches people out. The JO Series accommodates one door, not two, so a second entrance can't be added to a JOS-1F system. The JO-DVF door station in the set is also not sold separately. If you know you'll eventually cover a second entry, size for that at the start with a platform built for two doors rather than buying this set and expecting to expand it. Adding a second inside station is fine, up to two total.

Both are available. The JO-1MD inside station runs hands-free (VOX), so a receptionist can keep working and just answer, or you can switch it to push-to-talk (simplex) where one side talks at a time. Push-to-talk is the setting to use in a noisy lobby or near HVAC equipment, because VOX will chop the conversation when background noise keeps the channel open. The inside station uses electrostatic touch buttons rather than mechanical keys.

Yes. The JO Series does video identification and monitoring, so from the 7 inch LCD inside station you can call up the door camera on demand and look at the entry rather than waiting for a visitor to press the button. That's the function property managers and front desk staff use most after the initial install: check the door before unlocking it, or look at a noise outside. Bear in mind the camera's view area is 2 feet 1 inch by 3 feet 1 inch at 20 inches, so monitoring shows you the door face, not the parking lot.
