Aiphone NI-BA – Frequently Asked Questions
1) Will the Aiphone NI-BA sub station work with any intercom master, or only certain ones?
The NI-BA is an NIM Series sub station and it talks to an NIM master station. Call-in and 2-way audio both run through that master. If the head end in the building is not an NIM master, this is not the sub station to hang on it. Anyone extending an existing NIM system, though, can add NI-BA stations at the room or door end without changing the master.
2) How far can I run wire from the master station to an Aiphone NI-BA sub station?
Up to 650 feet using 18AWG. That distance is what decides whether one master can cover a full floor plate or a warehouse annex, so measure the actual pull route and not the straight-line distance between rooms. Go smaller than 18AWG and you are outside the stated rating.
3) What kind of cable does an Aiphone NI-BA intercom station need?
3 conductor overall shielded wire, with Aiphone #821803 called out as the specified type. The overall shield is the part contractors skip; plain unshielded 3-conductor will pass audio but it is not what the station is specified on. Pull the shielded cable during rough-in, since going back for it after the walls close is the expensive version of this job.
4) Does the Aiphone NI-BA mount on a wall or does it need a back box in the wall?
Surface mount. The NI-BA fastens directly to the wall face, or sits on a desk, so there is no cutting in and no recessed back box to set. That makes it the practical choice in block walls, existing finished corridors, and retrofits where opening the wall is not on the table.
5) Is the Aiphone NI-BA hands-free, or does someone have to pick up a handset to answer?
Hands-free, both directions. A person at the station can call in and hold a 2-way conversation without lifting anything, which is the reason these land in patient rooms, clean rooms, and any spot where the user's hands are busy or they cannot reach a handset.
6) Is the Aiphone NI-BA rated for commercial use or is it a residential intercom?
Commercial. It is used in office buildings, schools, healthcare facilities, retail, industrial and warehouse space, multi-tenant residential properties, and government buildings. Housing is plastic, which keeps it light on a surface mount but means it is an interior, protected-location station rather than something to hang on an exposed exterior wall.
7) Can I use the Aiphone NI-BA as a nurse call station?
The NIM Series it belongs to is deployed as a nurse call system, and the NI-BA is the sub station end of it: a resident or patient presses to call in and speaks hands-free to staff at the NIM master. Aiphone publishes an NIM nurse call system brochure covering how the stations are laid out across a facility. For a room where the occupant cannot reach a wall station, plan the station location and any pull-cord accessory accordingly, since the NI-BA itself is the surface wall or desk unit.
8) Does one Aiphone NI-BA cover a whole system, or do I order one per room?
One per station location. The NI-BA is a sub station, not a master, so it has no capability to select or supervise other stations, it calls in to the NIM master. Count your call-in points, order that many NI-BA units, and run each back on its own 3-conductor shielded home run within the 650 foot limit.
9) Is the Aiphone NI-BA audio only or does it have video?
Audio only. It is an audio intercom station: call-in plus 2-way voice. If the application needs to see who is at the point of call, such as an entry door where staff must identify a visitor before releasing it, an audio sub station will not do that job and a video door station is the right product type.
10) How do I order the Aiphone NI-BA, are there finish or option choices to specify?
There is a single configuration, model NI-BA, so there is nothing to spec on the order beyond quantity. The cable is the separate line item to remember: 3 conductor overall shielded, Aiphone #821803, plus the NIM master if the system is new rather than an expansion.
