Aiphone AT-306 – Frequently Asked Questions
1) How far can I run the wire between an Aiphone AT-306 handset sub station and the master station?
Wiring distance depends on gauge. In a 2-station set, the AT-306 runs up to 2,300 feet on 22AWG or 5,250 feet on 18AWG. If you're expanding, the run from the master to a 3rd sub station drops to 1,350 feet on 22AWG or 3,100 feet on 18AWG. Use 2-conductor, overall shielded cable, such as Aiphone 822202. On a campus or warehouse pull, that gauge choice is what decides whether the run makes it, so size the wire off the longest leg in the system, not the average.
2) Will the Aiphone AT-306 work with any Aiphone intercom, or only certain systems?
The AT-306 is built for the AT-406 Series intercom system and is meant to be wired into that system's master station. It is not a standalone intercom and it will not operate on its own, so you need an AT-406 Series master in place for it to do anything. If your building runs a different Aiphone platform, the AT-306 is the wrong sub station for it.
3) If someone calls from the AT-306 sub station, who does it ring?
The AT-306 rings the master station only. It cannot call another sub station directly. That's the routing model to plan around: every call from a sub goes to whoever is sitting at the master, which works for a front desk, a nurse station, or a guard post, and does not work if you need staff in two back rooms talking to each other without going through the master.
4) What's the difference between a handset sub station and an open-voice speaker station for an intercom?
A handset station like the AT-306 puts the conversation on a handset rather than a speaker, so nobody standing nearby hears the other end. It is full duplex, meaning both people can talk at once without pressing a talk button, the way a phone works. Pick the handset where the conversation is confidential, a pharmacy window, a records office, an HR room, an admissions desk. Pick an open-voice station where hands-free matters more than privacy, like a loading dock or a shop floor.
5) What do I need to order besides the AT-306 to get an intercom working?
The AT-306 is one sub station, and it is white. On its own it does nothing. You need an AT-406 Series master station for it to ring, plus 2-conductor overall shielded cable, such as Aiphone 822202, run between them. Order the cable to the gauge your distance demands, 18AWG buys you the longer run. If you're covering several rooms, each location needs its own sub station.
6) Can I add more than one AT-306 sub station to the same AT-406 master?
Yes, the AT-406 Series is a multi-station audio intercom network and the AT-306 is designed to sit in it as one of several subs. Note that the wiring budget tightens as you expand: master to a 3rd sub station is rated to 1,350 feet on 22AWG or 3,100 feet on 18AWG, against 2,300 feet and 5,250 feet for a simple 2-station set. Plan the cable runs for the expanded configuration you'll end up with, not the two stations you start with.
7) Does the AT-306 handset station need a shielded cable or will regular intercom wire do?
Shielded. The AT-306 calls for 2-conductor, overall shielded cable, and Aiphone's own 822202 is the wire named for it. On long runs through a commercial building, that shield is what keeps the audio clean past nearby power and lighting circuits, and the published distances, 2,300 feet on 22AWG and 5,250 feet on 18AWG for a 2-station set, assume that cable type.
8) Is the Aiphone AT-306 rated for commercial use or is it a residential intercom?
Commercial. The AT-306 is specified for commercial installations, and the typical settings are office buildings, schools, hospitals, retail, industrial and warehouse space, multi-tenant residential properties, and government buildings. Multi-tenant residential shows up on that list because the station lives on the management or staff side of the building, not in individual units.
